anyone able to shed some light on the process of re-burning your eprom, the guy who owed my car before me claims he did it, for a 10% increase.(he owns an IT company and his brother is a mechanic,they got together an did it) personally i think he's full of sh*t. anyone got some info?

It is possible with some ECUs (eg VL) but I dunno for the Magna.. is it possible to by replacement "Chips" from Chiptorque etc?
If not then I doubt it, cause that is pretty much all they do for commonhores as far as I can work out. From everything i've READ however, U need a piggyback for Mitsu vehicles... i know u do for lancers! :redface:

PROM: Programmable Read Only Memory - written once at manufacture, then to change it, you buy a new one.
EPROM: Erasable Programmable Read Only Memory - written at manufacture, then to change it, you expose the chip to UV light, and re-write all the stuff.
EEPROM: Electonically Erasable Programmable Read Only Memory - Hook it up to your computer, and edit the **** out of it.

To edit EPROM, you need to expose the chip to UV light, which erases the chip's memory. To write to the chip you short the appropriate junctions to give the desired output. There is software (and obviously associated hardware) that will do this for you, the kind of thing an IT specialist store will have.

Interprating what the current EPROM has is kind of like backwards engineering a well set out digital circuit (with AND and NOR gates and the like). Something an IT expert will be more than capable of doing.

Sounds interesting - anyone else thinking of buying a nerd they know a case of beer to bring their lap top and a UV light round for a few hours on the weekend??

But seriously - you drive the car now.... does it have an "extra 10%"? if so, why do you want to know how to do it??? you reckon there's some more ponies that can be unleashed?

spend some money under the bonnet and you'll find them me thinks.

Apparantly, all cars can have their ECU flashed once.. it's permanant and if you wanna add mods and tune again, you will need a new ECU...

Anyone can confirm this?

Most new ECU setups can be re-programmed, but only if the coding has been unlocked.
Manufactures use unique security codding to stop people tampering, but of course pople have had success simulating the "handshake" (signal telling the ECU it is hooked up to a factory interface) allowing them to modd at will.

I know you can re-program/edit the software on the DELCO ECUs in the VN-VR commodored as much as you like, same goes for the GenIII 5.7 in the newer holdens using the LS1 edit software. The new BA Falcon ECUs havn't been cracked yet so you are stuck with piggyback systems.

As for magnas I'm not sure, maybe they are of the old type that only get programmed once??? or maybe no has really tried playing with them due to low aftermarket demand (untill last couple years where everyone is modding Magnas :D )

i drive the car everyday, feels quick. raced another TH an killed it, think it was an auto though. i don't wanna know how to do it, i just wanted to know if it was possible. the guy actually said he got 10% out of it but was able to get 30% if i wanted but my fuel economy would be around 16lt/100km, at the moment its about 12lt/100. he also said he had a cd with the info on it, might hit him up for a copy, see if he's tellin the truth. this guy was a bit of a toss, said the car was lowered by ralliart too. even though i didn't believe much he said about the car i still bought it cause it was exactly what i was after. :D

Does a Software Engineering degree with a Digital Electronics minor count? :D

I played around quite abit a while back only to find the TE's are not OBD II compliant - that was when I gave up with my ECU efforts. I am tempted to have a good look at the guts of one though.

BOOYA: do you still have your stock TE ECU sitting around? If you could take some hi-res shots of the front and back of the boards that would help me a lot. The part numbers on the IC's will give me everything I need to see what can/can't be done.

-Dan

the TE+ should be OBD II compliant... the TH's are and its pretty much the same engine... and all cars from 96 are to have it by law, in Japan i'm sure they were using it earlier!!

i'm not sure what the chip in the Magna's are, but from what i've researched (and as Mitsiman said) no one has reverse engineered it yet, searching the Jap sites and no one has done it there either!!

Dingo,

last year I did quite alot of research into this.. in the end I built my own OBD II interface to read data from my car. I had plans of an LCD display with all the different sensor readings, RMP, km/h etc etc.
Anyway, all the reading I ever found says that from 1996 cars had to be OBD II compliant in the 'states and europe, but in Australia we have never had such a law. I found a board where other people have tried the same thing.. I know for certain the 96 Diamante IS OBD II compliant, but could never find out about our Magnas. The TE+ do have an OBDII connector, but my interface was never able to achieve any communication with the car.

I never did try it on any other car though, so I never was 100% certain that it was the cars fault (it could be my soldering at fault) - although the board I built has a self-diagnostic which passes, so I think the board is fine, it's the car.

If you can provide me with any more/new info on this, I would be greatful. How do you know for certain the TH's are compliant?

Can anyone find out for 100% if the TE+ Magnas are OBDII compliant?

-Dan

Thats right the OBDII laws where for the states originally.

The only hope we have since the Diamantes are ODBII complient and were made here, that we also use the same ECUs in the local market Magnas. But I have a feeling Mitsu might have gone cheaper and used a lower spec ECU :confused:

Well if no one has really bothered to try hacking around with the ECU, well lets do it! :D

yo Grecy, we'll go find an abandoned TE+ ECU and do a bit of logic reverse engineering. This would be a good time to test my new osciiloscope :P


BLKMAG: If the guy is telling the truth, grab the CD off him, we'll need all the info we can get.

This sounds like FUN :D

I'm definately up for it, but I've done everything I can in terms of the OBDII interface. Unless someone can tell me categorically they are or are not compiant, I'm kinda at a dead end.

First thing for me to do would be have a look at some hi-res shots of the board so we can see what they are using. Also it would be great to get some wiring diagrams or the internals of the ecu (highly unlikely).
Maybe someone who is in with Mitsubishi can help us out.

-Dan

My local Mitsubishi dealer claimed to have reflashed my ECU firmware with the latest version when I took my TJ to them about an auto 4>3 kickdown issue.

Ever since they've done this, my trip computer's average fuel display starts instantly calcuating usage after a reset now*. Where as before, the average fuel would not be displayed for the first couple of minutes after resetting the trip stats.

Where's some info on building a OBDII display? That would be a cool rice mod :D


------
*(And since it's calcuating an average using so little data, it normally displays some scary figure like 30L+ average! - then it drops back to normal after a few minutes of driving)

Well I don't have access to a 3rd gen Magna as of yet, so I don't even know if they use an ODBII interface or a proprietry diagnostic interface. However the Diamantes over in North America does have ODBII because its a requirement for all vehicles built after 1996 to have one.

Grecy: Did you know theres actually three different types of ODBII interfaces? You might have tried to use the wrong one, and so it didnt work. I'm planning on getting one of these interface IC's (http://www.elmelectronics.com/thehome.html somewhere in the middle of the page) once I do know which one we are after. Should we safely assume that since DaimlerChrysler were one of the major owners of Mitsu that they would have used the same OBDII interface as the Daimlerchryler's vehicles???


If the Aussie Magna's don't use the OBDII interface, then this whole thing wont work, and we would need to go low level into the ECU to work out ways of interfacing and getting data.

i'm keen to work it out once and for all.... i was told by my mechanic that the TH was OBCII compliant as he could plug his computer thingy (those specially made for mechanics that fit all cars) so i'm just going with what he said... maybe its a different version,i dunno..... i got a test tomorrow and thursday so i wont be doing much till the weekend, but i'll definately chime in then!!

That interface is exactly what I built. I found a page a one time that was a registry for people to list what kind of interface their car was. I found out the 96 Diamantes in Japan and the US were all OBDII ISO compiant. If I remember correctly, Mitsubishi have never used anything other than ISO.
That is the interface I built, and it didn't work with my TE.

Next meet I should bring it along and try it out on a TH or TJ to see if we have better luck.

I've been chasing info on the ECU for the 2 auto types and found out some stuff this arvo.
Mitsu told me to ring EMF the ECU repair place that they use.
I spoke with Trevor (very helpful) and he told me that they repair heaps of TR/S ECU's but without the Mitsu MUTII they can't do anything with the later ones.
However they are OBDII and you should be able to hook in and view diag stuff.
I asked about changing the "Firmware" and his response was "the software is encrypted :mad: and loaded into each ECU in the car to match the car. Can't do anything with them out of the car, yet.

I don't really know what OBDII is so I didn't know the best questions to ask so if you guys want his phone Number it's (07) 3000 4000 Trevor (most helpful) or Brett but prehaps just one of you could ring otherwise it may get a bit much.

Phil - did you ask him about the tiptronic buttons question?

I asked about changing the "Firmware" and his response was "the software is encrypted :mad: and loaded into each ECU in the car to match the car. Can't do anything with them out of the car, yet.

According to him they are ODBII complient so thats good. But what is potentially even better is that according to him it IS possible to re-program the ECUs if you possesed the correct key to gain access to the programming. Now to find someone interested in spending time to 'crack' the Mitsu ECUs and make some software that allowed re-programming (eg: ECUTEK for subarus, LS1edit for GenIII Holdens etc..). But I don't htink that'll happen anytime soon (if ever) as there really isn't that much aftermarket demand.....but you never know :P

Hey,

Thanks for the info. I'm very interested to hear they are OBDII compliant.
If I wasn't so busy right now I'd give that guy a call and have a chat with him.
When I go back home in a few weeks I'll dig out my old OBDII interface and see what I can figure out.

The news that the ECU *is* reprogrammable is very interesting. I'm beginning to wonder if the acess to the chip is encrypted (like can be done with PIC mircos) or just the data on the chip is encrypted.
What I'm thinking is that if it's just the data, and you can still flash it, then you could ROM dump a ralliart, and flash that onto any third gen. Of course your ECU then assumes you have the cams etc to go with it all - but it's definately a big start.
After that for fully custom work it would be a matter of breaking into the ROM - which in theory shouldn't be all that difficult - it's just a matter of time and patience really.

-Dan

i'm excited!! damn exams :rant: i wanna play!

(turns around and walks back to desk to study :cry: )

Go for it, I'm following with interest.

Behind the audio system.

totally forgot about this lol

i'll send this bloke a message tomorrow

I have an old SOHC 12v 6G72 ECU sitting in my room if someone wants to have a go at that.

I'm willing to let someone have a go at it, but if it gets ruined you will have to pay for it as I could get money for selling it.

Hope that's fair and reasonable...

i won't be touchin it lol

Greetings All.

Interested and following closely!

called and messaged the guy today, he said he'll call me tonight.

i won't be touchin it lol


LOL that's ok mate, thought i'd throw the offer in.

I've been meaning to do a bit of reverse engineering on the ECU's myself, as I have the expertise in finite state logic devices. However I just don't have any funds at the moment to buy a second ECU.

KB I might take your offer, but I was hoping to get hold of a 3rd gen ECU rather then a 2nd gen ECU. They have quite a number of different features, and for the fact that the 3rd gen ECU has some sort of handshaking algorithm to verify the uniquely identified BCM and security module.

Just so ya'all know what I have been thru with ECU's

Had some problems with my 3L TF manual after putting a dose of octane booster in it. With a gutful of Optimax. And Injector cleaner.......don't do it peoples.... ended up that I destroyed the dizzy or something....
anywayz

The Mitsu dealer tech said that there were some fuel curve issues in the 3L manual TF when cold (lumpy running, especially when 'on choke') so they 'flashed' a new fuel curve into the computer with the mitsu computer hookup thingy.

They had a old ECU out the back that had not been flashed, since mine had been done. They decided if they couldn't work out the issue with my car, they would drop an unflashed ECU into it to check it out....

You MIGHT (and I stress might) be able to pick up some old ECUs from dealers. Especially if you get your car serviced there. It might only cost you a token amount to take them away. My then mechanic at the dealership said he had multiples in a pile(!) and they were taking up space.

Another ECU question: a number of us use GReddy E-manages, has anyone used anything else more exotic for that computer, like an Apexi PowerFC? Just wondering what all the options are. I like to take a path sightly less travelled myselfs...

I believe Booya is running an Apexi of some description in his gold beast.

Cheers, will PM him to find out more.

Anyone else? Anyone got Wolf's, MoTec's, Haltech's, etc?

Booya has a Haltech, I believe :)

Yes, Booya is running a Haltec...56K or something like that!

who else does aftermarket/replacement chips for Magnas?? ive got a 89 TP elante.
i had a look at the ChipTorque website and they only do performance chips for Lancer and Galant Turbos.

any help pls?

booyas ecu is the E6K.

I know you can re-program/edit the software on the DELCO ECUs in the VN-VR commodored as much as you like,
so if u can reprogram a vn ecu can u reprogram it to run an a astron 2.6 :confused:

so if u can reprogram a vn ecu can u reprogram it to run an a astron 2.6

Surely can - so long as you fit the appropriate sensors onto the astron...

(I'm almost done converting the VN ecu to my VH 202....)

Cheers,

Dave

on the point of ECUS i have a Haltech E6K like booyas for sale BRAND NEW

pm me

Behind the audio system.

in the 2nd gen thats the auto transmission computer, the ecu is on the passenger side above the kick panell (mounted on the chasis next to the glove box)

well its offical, the guy i bought my car from is full of sh*t! nothings been done to my computer.

the wanker tried to tell me that his mate has a brand new magna thats worked as with a "phase III" chip, when he took off at a set of lights the seat snapped with him in it lol :gtfo:

i didn't listen to a word he said when i was buying the car, i let the RACQ test do the talking.

sorry to get your hopes up guys, but who knows it could be possible but i doubt it
