This thread is now for dicussion of Magna ECU Flashing

forget about putting diamante ecu's into our cars, ive realised we're running the same or similar ecu the diamante so it would be a pointless excerise

Theres a whole mess of different engine configurations for a Diamante, I'm sure most if not all of them are DOHC or DOHC Mivec variants - So i'd imagine it would have more inputs and parameters for running.

apparently alot of the 3rd gen shapped one are SOHC... i no there are other engines but a SOHC ecu?

Can't see why not. If engine configs were identical, it should be a matter of plug and play, unless the Diamante had extra functions in the ECU for emissions and even then...

true story... just had great success with ecuflash on my evo ... very easy to use. and the same platform supports diamante's.. was thinking about finding one an having a go with it in my TH...

Why not? If you've got or can get one it'd be worth a try.

Might or might no help you, but I know for a fact the Dimante ecu can be reflashed. Theres alot of funky stuff you can do with it.

yes i no, hence the interest

what even more interesting is that i just found this out

DIAMANTE 99 Elec Cont Unit (ECU); (center dash), w/o traction control
Ident: MD354193
BOSCH F005 E0 0022

now i thought the problem here was that we used bosch ecu's and the rest of the world had something else.. it appears not

im starting to think steve knight hasnt cracked anything what so ever and has just caught onto the very thing that i have too...

he flashes evo's, as do i, and i reckon he has also caught onto the fact that ecuflash works with diamante's aswell so now he uses diamante rom's and definitions to read and re-flash our local magnas... thats my guess


im guna try read my TH on ecuflash with diamante definitions.. ill let u no how i go... might have a cheaper alternative for you guys posting your ecu's to steve knight :)

If you saw the "flash" tool that he uses on the evo's and the one he uses for the magnas then you would see there vastly different to eachother.

As a side note, you can read a magna ECU with the simple link cable and software BUT the program upload is where it seems to fail.....

whats he using for magna and whats he using for evo flashing?

is he using ecutek with evo's? if so thats rubbish... why not use ecuflash?

ill let u no how i go...

He doesnt use ecutek at all (as far as i know), he uses MMC software and some link cable (open ecu?) etc for the EVO's.

For the magna he uses the genuine MMC/MMAL flashbox setup (looks like a small breifcase) and a laptop that he bought direct from engineering when the magna was replaced by the 380 (the 380 uses a different ecu setup)

mmc software for the evo's eh? interesting....
openecu are the guys who created ecuflash... the cable he has its what i use.. its from limitless (they are linked to openecu in a way)


interesting about the flashbox setup for magnas...

ill prob fail with ecuflash but its working on diamantes so i need to try it for myself to get the idea out of my head

No harm in giving it a try. The biggest hurdle so i was told is unlocking the security codes that the aussie magna ecu has on it, once that is done its easier.

All so all pre 2000 (approx) model magna/verada ECU's used hexdecimal coding where as the later 2000 onwards used the easier numerical coding

intersting info man. cheers...

i might hit up one of the aussie guys whos heavily involved with openecu. see if his interested in having a go with the magna...


makes me wonder who locked the aussie ecu and why?...

I guess anything can be achieved if time is devoted to it, but being a magna it of course gets thrown into the "too hard" basket and people just get back to flogging off commodore crap

The ECU lock was done by the nips to hold control over them damn aussies LOL :io:

From Openecu re: flashing austrlian magna: (havnet got the actual pics sorry)

USERONE:
Pics of the Magna ECU board can be seen
here, here, and here.

Higher res shots showing the main IC details can be seen here

It appears the manual transmission cars use "MH8206F" while the auto's use "MH8305F".

The ECU board from this car looks almost identical to one shown here of a Mitsubishi Evo ECU. Another member of my car club has also been in contact with Mynesperformance.com in the US and they think that as long as we're running a "MH8206F" flashing will be possible using the EVO-supported version of OpenECU

USERTWO


Yes. I can't promise anything, but that is the same processor (SH7052) that is used in the Evo 7/8. If it's like everything else we've seen from Mitsubishi, the init sequence will be the same, and you should be able to read / reflash it without any problems. Be sure to post your ROM image once you do!

Colby,

Thanks for the reply !

For a long time here in Australia we've all believed we couldn't flash these ECU's because they were "encrypted".
(I don't think anyone's actually *confirmed* this)

Recently I've also gotten info that the so called "encryption" is related to the factory immobilizer

That makes more sense the more i think of it because when the MUT-II is hooked up to my car it comes up with immobilizer link broken and i was told by a reliable source that that then means my ECU can be fitted into any 3rd Gen manual magna and the car will start/run as per normal due to the immobiliser link being "switched" off to my ECU.

Have you thought about ringing Steve and asking him about the hows and whys of late model magna ECU encyption?

havent man... but i might


just to let u no, same issue with evo ecu.. u cant just chuck it into another evo, immob. will stop u.. BUT can turn off the immob. in ecuflash in 5secs on evo... change one paramater and the immob. check is turned off..

possibly the same on the magna ecu..

ill plug in my tactrix cable (same cable as steve's) to my laptop tommorow and fire up ecuflash and let ya no how it responds...

this is very interesting information, will be watching closely to see how this progresses.

Yep thats the same as the magna, i have 3 ECU's that have the immobiliser switched off and they can all be used on my car with no trouble

doin well gremlin! keep it up!

more info.. the mitsu eclipse used same ecu as magna as some point in time (dunno which magna, dunno which eclipse)

but

eclipse has had:

4g63T at one point (evo motor)
6g72 24 valve at one point (3rd gen 3.0L)
6g75 aswell (380 motor)

ppl are also flashing eclipse's left right and centre

to much work on today to try the TH... but will definitly try tonight

so far we have confirmation that evo 7&8 ecu share the same processor chip as a magna in one model (that bloke who compared the two didnt list what model magna he had).....

be funny if the magna ecu is basically the same ecu re-tuned to run the 6 cylinder magna :D ..

Jason, can you give me any more detail on the changes of ecu's throught the 3rd gens life?

im starting to think i may have better luck with a later model TJ than my TH as the TJ is the same age as evo 7 & 8s.. where as my TH is 99, is same as evo6 ... and even the openecu guys are having a harder time with the evo6... althought i believe guys are writing to them now..

i wonder if the TE, TF, TH magnas share the ecu of the evo5&6 and as a result are a bit harder to crack?

whereas the TJ, TL,TW might share the ecu of 7 & 8s which would mean easy to read and write too

TJ+ is also non hexidecimal IIRC?


im hitting the wreckers this weekend if i find a tj ill rip the ecu out for ya

TJ+ is also non hexidecimal IIRC?


im hitting the wreckers this weekend if i find a tj ill rip the ecu out for ya

good idea! shouldnt cost much for an ecu should it?

besides the immob. (which i can get around without even starting the car, if same as an evo),a TJ ecu should run a TH right? ..my car is 3.5L manual so no autobox to worry about

guys minor progress..

jason_vrx has mentioned that ppl have read magna ecu's but are unable to write to them.. i can confirm this.. i just read my TH Magna... i selected evo 5/6 from the list of cars and it downloaded the ecu rom to my pc... it is attached for your interest.. right now i cant do anything with it as i dont have a xml definition file to suit that allows me to modify parameters of the ecu.. im on the hunt for a compatible xml as we speak .. im thinking evo 5/6 or an eclipse of some kind...

now Jason has told us ppl have read them before but couldnt write back to them.. info from openecu might explain this... (bit of background info.. the most popular cable was the openport 1.3..its what i have...theres a new one out that fixes the problem decribed below)....

"we will not be able to release a version of EcuFlash for the Mitsubishi H8 processor family of ECUs that works with the Openport 1.3. The reason being that the Openport 1.3 power supply circuit that generates the ~16V the ECU needs to supply the regulated reflashing voltage to the CPU does not have a sufficient current capacity, causing this voltage to drop to levels insufficient to safely flash the CPU (the CPU goes into a protection mode to prevent you from even trying). The Openport 1.3 does generate a voltage large enough to cause the processor to startup in boot mode, which is why you could read and compare in past versions, but unfortunately, it just isn't usable for reflashing. Later processors like the SH2 and M32R generate this reflash voltage internally, and have minimal current requirements, which is why the Openport 1.3 works with the Evo 7/8/9 without a problem."

in simple terms what it saying is early ecu's cant be written to because of the current capacity issues of the cables power supply... BUT later ecu's generate the voltage internally hence why they have been working fine with the 1.3 version of the cable.. the newer cable is able to flash older ecu's...

if i can find an xml to work with this rom off my TH i will then buy the cable and im pretty sure ill be able to flash my TH ecu... even if i cant find a xml ill ask our australian openecu friend if he'll write me one..ill send him the TH hex file and see what he can do..

any programming guru's feel free to grab the hex file and see what you can do with it..

i initially tried selecting evo 7/8 from the list to use.. this hung ecuflash

attempted again with evo 6 as the car and it worked.. interesting how TH came out in 99 and so did the evo 6 :)

*****cant we attach files these days? anyone who wants it PM me your email and ill send it***

sounds awsome mate, can you send me the file?
i have a mate who is a decent programer, ill give it to him and see wat he can do with it.
oh and if you need a spare TH ecu to work on/experiment i have one you can borrow :)
EDIT: PM sent

email sent mate...

more info

non of which is any suprise to me

read 2 TJs tonight.. both read using evo 7/8 init codes..

so TH uses evo6 init codes.. both evo6 and TH are 99 model cars

TJ uses evo 7/8 init codes.. both evo7/8 and TJ are 2001-2003 cars

considering the difficulty flashing evo6s and the ease of flashing evo7/8s im 95% sure i can flash a TJ and not to sure about a TH or older.. maybe with the new cable i will be able to...

forget anything about being locked.. i dont believe that one little bit anymore.. there on about the immob. code which is so easy to override its not funny

i'll let u no when i flashed a TJ.. wont be long now..

also man i have a spare ecu as well.. really unsure of what it is outta but its a 3.5... ill get the part number off it tomorrow and post it up, may be some help if its a newer ecu for you to play with!

edit.. just went and got it now.. part number is MR507346, above it, it says TJ9S42

so id guess its a tj.. so you have a spare tj ecu here too if ya need it!

im really in need of a tj ecu hey!

ill be in touch so mate

thanks

this is starting to look interesting, will be monitoring this thread for updates!

ive managed to locate the rom id's for all 3 rom's i have pulled... its at the same address on the ecu as every other mitsu rom so far, no suprise there i guess hey

interesting find already.. TJ series 1 sports and a series 2 exec are different.. well, they're the same rom but the series1 sports its running the original 87250000 and the series 2 exec is running 87520005 .. so revision 5..

ive also managed to pull the stock fuel map out of it.. the scaling on the map is a bit of a mess but the AFR's are all readable.. suprisingly the stock TJ fuel map is a lot leaner than i expected for a factory car... this might explain why people aren't seeing massive inreases in power from piggybacks as most tuners gain alot from leaning the car out but if the stock TJ map is quite lean already it kinda takes away from those gains that other factory cars see with a tune.. obviously gains are there to be had when re-tuning for 98oct but not as much as other cars i dont reckon.... havent got timing maps yet, still working on em...

also got access to the immob. code.. havent located code to turn it off yet.. BUT this mean i could move your immob. code to antother ecu.... in other words, if you wanted to put another TJ ecu into another TJ i can move your immob. code so u can keep your BCM, barrells and keys... pretty much what mistu would do when they "code" your ecu to your keys etc....

all info currently pulled from the rom has been done using eclipse 3litre definition files...

so to recap.. the TJ magna ecu is talking the same language as a evo7/8 & 3g eclipse (3g eclipse and evo7/8 are same setting in ecuflash) ...definitions are a bit more precise as they start addressing fuel, timing, idle etc etc on the rom.. therefore obviously an evo definition wont work as the car has a very different engine setup.. whereas the 3.0litre eclipse is damn close to our cars....

have you tried writing the tj rom back to the ecu yet?

have you tried writing the tj rom back to the ecu yet?

not yet... afraid to atm as neither of the TJ's are my cars.... i dont wana stuff someone else's car... then im in deep trouble

i want to get my hands a on TJ ecu.. plug it into my TH and read write etc etc.. not big deal if i bugger a spare ecu.. and not big deal if TH is off the road for some period of time if everything turns out bad.. got the evo to drive to work in worst case scenario :)

might be a silly question mate but if you can fiddle with the ecu settings does that mean you can get rid of the speed limiter?

Yes it does. The speed limiter and rev limiter are both stored in the ECU I believe.

i would find advancing the ignition timing and running it on 98 RON would be of greater benifit :)

i would be VERY interested in a tune to 98RON :woot:

ok now a how to would be good lol. im mechanicly minded but..... need a push in the right direction. im disapointed my manual has the speed limiter it just feels like it wants to keep going but alas in comes the limiter.

well this is what chris (gremlin) is trying to find out, but its a matter of telling the ecu by playing with the settings, to ignite the spart slightly earlier in the compression stroke.

:nuts: :nuts: :nuts: are you saying you regularly take your car over 200Km/h??????

perhaps you ment the rev limiter? which i would leave on, to avoid engine damage. no point having a stock engine, with stock cams, reving that high as its only going to loose power

:nuts: :nuts: are you saying you regularly take your car over 200Km/h??????


:hmm: :ninja: NO! :disgusted

:hmm: :ninja: NO! :disgusted

The speed limiter doesn't soften your acceleration, it merely a cap set at 2XX (whatever it is).

So unless you are actually traveling that fast, then you will never have even encountered the speed limiter.

The rev limiter is a different story, however, it pretty noticeable once you hit it, and i assume you aren't pinging off it every day ?

guys yes i will be able to remove the speed limiter and increases or remove your rev limiter if you wanted ... if i can find those addreses on the ecu rom.. they're there... its a matter of finding them and then we can modify them..

im working guys.. those ppl who have PM's me asking for the rom's, ill get them to you asap.. there on my laptop.. my laptop isnt with me right now..

On public roads?

i offer my tj as a "guinea pig"... well sorta... i need it to drive... LOL. but i mihgt just go look for some tj ecu's for you as i am interested in the tune also!!!

hey guys, im still working away.. ill update when i get any useful info....

we are basically at the position now the evo's were a couple of years back before openecu guys worked hard and located all the address' for the different paramater... in saying that, to this day there still finding new stuff and new features for the evo's...


obviously first objective is to define the address' for fuel and timing maps so we can do some basic tuning of the car (tune for 98oct as ppl are suggesting)... this on its own will make the unichip's etc obselete....

other things the evo has that id like to see on a magna is launch control (stationary rev limit)... great for fwd drive.. if car is less than set speed (normally 10km/h) the ecu switches to a secondary rev limit that u can set.. my evo is to to 5,500rpm.. so at the drags to launch is,all i do is put my foot flat to the floor, the car sits at 5,500rpm.. lights go green, i pull the clutch out and get awesome launches .. makes launches far more consistent... of course, once the car has left stand still the ecu goes straight back to normal rev limit so u can winde out first gear to 7,000 rpm.. not sure what would be good for a magna, maybe 3,500rpm? anyway, rpm is something u set so pick whatever rpm u like

sounds awsome mate, cant wait!
stuff getting a new aftermarket ECU, for our cars, when we can easily flash our stock ecu, while still leaving it in the car, rather than sending the ecu off to another state.
but you say you cant do TH ECU's????? or is it still on the playing cards?
if so i could stick that spare TH ecu into my TF, any that would work, as TFs dont have BEM's

Gremlin this is awesome work man, very proud of what your doing.

TH is in the same basket as evo 5,6 and the older eclipse (1999ish)... there just getting them going now on openecu.... i will need a new cable though no matter what cause of the voltage problem... i'll get a cable...

but i mean, worst case scenario would be stick a TJ ecu in it.. (since the e7,8 ecu's have been flash able all the evo 5,6 guys put evo 7,8 ecu into there cars)..

i put an US evo8 ecu into my brothers jap 6 for him.. worked a treat ..we flashed it with ralliart timing and fuel maps (taken off a geniune plug and plug ralliart ecu by someone), turned the rubbish factory immob. off, turn the speed limiter off, set the launch control and his loving it.. cost him $300 AUD installed into the car.. talk about bang for buck.. the best $300 mod ive seen done to any car to do date :) .. because of the ralliart maps, he was able to take the boost from 1bar to 1.5 bar (ralliart maps are designed for this). the car went from running 13.8 to 12.7 overnight.. dropped 0.9sec off his 1/4 mile time for $300!! :)

yeah almost 1 second gain for $300 thats awsome value, well hope you can sort out the TH/TF ecus, that would be even easier, if you cant, i wounder how much TJ ecus are? but would they even work, ie plugs all the same?

hey mate, just sent you e-mail, found a program that looks interesting, did a search on the TH CPU model number and came across it. worth a look.

hey mate, for jason_vrx confirmed for me that TJ ecu fits straight into TH

not bad.. but its guna be a long road ahead.. this will be like weeks away.. not days... i have so much respect for what the guys have done on the evo ecu after seeing how involved this is..

dont worry, my spare time is being spent on this.. we will flash magne ecu's soon, believe me

so gremlin what would be involved in cracking the ECU and is there some way i can learn how,reason i ask is have a lot of time spare at work which is in my car and i'd like to help if i can,PM if you like.

got any programming background?

nah i don't is it hard to learn? i have an auto TW so would i need a 1.3 or a 2.0 cable to write to the rom?

mate, im in IT.. and im having fun with all this.. prob a bit hard to learn computer science then ecu reverse engineering all one one go aye? :)

thanks for the offer though mate...

lol no worries mate,keep us updated

hey, i realise u got job and a life and etc, but was just wondering if there was any progress?

LOL

im holidaying in california at the moment.. i get back in june so not much will happen until then..

but just to let u no, before i left i was able to write back to a TJ... so.. i flashed the car.. all that has to happen now is get the tables into ecuflash for our cars.. this is a painful/difficult thing so it will take some time..

but in simple terms i can read and write from a TJ ecu..

i already have the fuel map in front of me so if i wanted to i could adjust the fuel maps..but of course i dont want to be mucking around with fueling yet so i havent done that

Very impressive gremlin,

If you don't mind, are you able to post a list of the equipment we will need to do this, the cables that you used.

have a look at this site it should answer most of your questions.

correct

So how did you go with trying to unlock a TJ ECU?

he is still in the USA, but as far as i know, he was able to read and im pretty sure was able to write, to the TJ ecu.
he just needed to figure out what paramaters needed to be changed.
as far as TH goes, thats a bit harder, as apparently there is a voltage drop using the current setup, and its not fully powering up the ECU, enough to write to it.
but it may be possible in the future

he just needed to figure out what paramaters needed to be changed.
as far as TH goes, thats a bit harder, as apparently there is a voltage drop using the current setup, and its not fully powering up the ECU, enough to write to it.
but it may be possible in the future

plus TH and before models use hexdecimal coding so are a bit more of a pain to write to.

TJ onwards (and the very very last of the TH models) use normal numeric coding which is alot easier when data "writing"

hi guys

just got back from from california holiday

as lowrider has said i have read and written to TJ magna ecu's..

TH should be possible with the later version of the cable (they're in the same basket as evo5/6)

i will continue working on this now and post any updates here

What is the difference between the Hexadecimal ECU and the numeric coded one as I have a late model TH and whould like to check it.

There is no pyhsical difference between them in looks and if you were to have them side by side you wouldnt know which is which. Its only when you download the ECU files that you will see if you need to "write" in hexdecimal or numerical coding back to the ECU.

hi mate just wondering where u got the rom's from???

Hey, i have never seen a sohc 6G72 (3l) or 6G73(2.5l) in any jap made imports, they are all DOHC as far as i know, i see HEAPS at wreckers and pic a part.
Oh ill go tommorow and get a ECU from a jap spec diamante and take pics for ya. will that help?? hell ill send ya a few if ya want!!. there would be 2 or 3 there at a time, plus the 1st gen diamantes are there, AWD etc

hi mate just wondering where u got the rom's from???

i pulled them off the ecu's myself

Extracted the files sounds better lol

Hey mate,

Love your dedication- getting flashed ECU's to the magna owners!

Have you made any progress since your last post?

Love your work Chris, interesting read. keep it up mate :)

Does anyone know if Gemlin is able to be contacted..MY ECU is crapped and the new one needs to be flashed and I think he is close enough to get to to have it done..Thanks in advance

Why does the new one need to be flashed? Because of the BEM?

hey mate, whats the go with ur ecu? is it dead? whats the car doing to make mitsu/you think its the ecu?

if i can still read your old ecu i can pull the immob. code off it and flash it to the new ecu you wish to put in the car...

do you have a new ecu already? i have an ecu here suitable for KJ/TJ 4 speed tippy WITHOUT traction control... is this what your car is?

chris

Hi Chris.. Been at mitsu since November..Got a matching numbered ECU for series 2 KJ,has 5 speed and t/c...They had the old ECU tested and it is faulty.Car will start cold then not as soon as the ecu has power go through it till cold again...They tried the matching numbered ecu this morning,I have had to do every thing they are useless and family life in my little run around accent is sending me mad..
I need the new/second hand one flashed for the existing gear..if possible..Where actually are you and is it possible to drive to you with the old one and have you do the new one or leave it there..If I stop it when I get there you have it for the day till it cools down..Looks like about $800.00 labor from Mitsu and they have actually fixed nothing..

i havent read whole thread yet, so hope this post isnt pointless. There are the jap spec 3rd gen shape diamantes here in NZ, they all run DOHC 2.5l 0r 3.0l DOHC engines, some MIVEC, some GDI, some with VERTICAL VORTEX (different head design for a leaner mixture burn i think), there are also Aussie built 3rd gen Diamantes (magnas,veradas) like mine. I dont see many aussie ones around, alot of jap spec ones. I havent come across a Aussie 3rd gen at pickapart, all japspec ones (why you love me lol) but if i do, i will send you an ecu if your interested. Also, i can get the numbers of my ECU (KE Diamante 3.5l auto) if you like for comparision.

Thanks robbsei..Problem seems that it may be solved in a few days..Been an ordeal but hopefully with the help of Gremlin I should have the missus back on the road and my sanity back in check..

Ha good luck, with a women you will never have any sanity lol (im married:happy:), any way i read the thread and realised i did offer gremlin an ECU last year. would be keen to see if this works.

This truly is BS...rang to see if they had put the old ECU in and started so I could pick up and they tell me the car will not go now and they will have to "" REDIAGNOSE "" the problem to fix that before I can take the car to fix the "" original "" problem...Then went through the speach about how a simple bump may have caused the problem and travel with the courier may have made it worse..Are these cars or model planes..Man I have had Mitsubishi techs..They suck..More money,no results,no repairs yet..

I wouldnt pay them a cent- get your car out of there

If it would go it would be gone!.It went in there working,albeit only when the ECU was cold..Now no go full stop..

So waht was the initial problem in the first place

When the car started cold no worries..If you drove anywhere it would not start for a few minutes..This gradually got longer and longer till it began to take hours to half a day..I got sick of chasing the wife to either try to start the car or pick her up..So a mates mechanic used to work at mitsubishi and had a computer to plug in so I went and saw him...When I arrived the car was going and he plugged the computer in,no problems showed.I turned the car off and tried to start it and no go so he plugged the computer in and would not comunicate..He was stuck with it for the night..Next morning same again so he sent it to his electrician mate and same deal so they said the only people could read it was Mitsu so away we went.Same happened to them and then it started.2 weeks to diagnose the problem as they had to test everything that led them back to the ECU ,eventually..When it got warm and would not start the ecu went in the fridge for 5 min and away it went...Then the quote to replace as you know was astronomical,so they had an ECU "guru" in Sydney who may be able to repair it so another 2 weeks later still no joy he could not fix it but said there was a fault.
Suddenly,although I asked at the beginning if a second hand could be used and told no,suddenly they were looking for a second hand one..2 more weeks later and sick to death I began doing my home work and found you guys who have been helpful and started searching myself for a second hand one..2 days and I found one..These guys are supposed to be the experts and I am doing their work and teaching them.
Any way I tried to get it out of there and to Gremlin but now they say it will not start at all even with the old ECU.It was atleast working before they started on it now no go at all..

Didn't they try another ECU? Seems like a no-brainer to me!

Is not quite as simple as throwing in another ecu

I am surprised that they just assume ecu is buggered, assumption is the mother of all fu....oops mistakes

very interested in this. i will deffinately be monitoring this for any more news :)

out of curiosity though, once everything is understood about the ecu you have been working on [TJ?] will that information be able to be used on other models? TL for instance? i understand the TH and older require different equipment, but the newer models are simpler to write to?

also would this whole process need to be done on each individual type? ie TJ manual, TJ auto, TL manual, TL auto, FWD, AWD etc?

OK..A couple of days to recover from the ordeal and here is the result..A half hour visit to Gremlin and the problem was solved with the ecu..Nearly two months at Mitsubishi dealer and not even near a result..So I learned a very valuable lesson..Hope that is obvious to all...
Car going great and the wife even thinks it is better,in her head I believe but while she is happy then I am..
