i have emailed the chaps in the usa re a program to edit the ecu

they have asked for pics of ecu's and in particular the chip inside the case

does anyone have some pics of tj2/tl ecu's and chip/board that they couyld post plse

regards

simon

there is a mob in the USA that has written or has access to the factory mitsi software codes (or has written an equuivelent) - and they claim that its possoble to reprogram the std ecu . .. .ie modify fuel/ign curves and adjust oter engine parameters - like rev limits, auto change points etc etc etc

they need to know what the inards of the std mitsi ecu look like to answer IF the aussie magna ecu's are reporgamable .. .

hence if anyone has some pics of the ecu chips/boards - plse post

rgds

simon oaten

Theres a fellow on this forum that may be able to assist. Why bother sending it to the USA to get it done. Hopefully he will chime in.

have contacted Jason - and he is going to try and get some pics of the inards of the ecu's. . . . he lives quite some way from his car. . .so will be difficult.


anyone else have a tj2 or tl ecu lying around that they would take the top of and post pics of boards/chips .. . . ..


one would think that there would be a reasonable market - and at reasonable cost (?) of modifiing the std ecu rather than using a piggyback or replacement ecu


anyone else have any interesting ideas out there

regards

simon

I have just taken some pics of a 2002 TJ 3.5 exec computer. I will upload pics for u soon

Simon here some TJ Exec ECU board pictures as requested:

Jason, all others interested

thankyou Jason!

Nice, have they given an approximate price for this software?

I'm interested! Keep the info coming.

Any news on this thread..........am very interested on hearing about reflashing original 3rd Gen ECU's

Keep us posted!

Me too! i'm interested

I think this has been visited before and the word from MMAL was that the software/maps are encrypted and good luck getting the key.

The encryption isnt the problem, mine was cracked in under 5minutes (admitedly by a mate in R&D) :D and the word was back in 2001 that software "was" going to be made available but no one could or would say when.

Jason,

Sorry to be a pain, but is there any way you can get a higher-res pic?

What I really need is everything that is written on each individual IC. (ie, letters, numbers, brand etc).

Maybe you could write it all out then indicate which it belongs to.

Thanks mate,

ooh hang on a tic, I thought I'd crosscheck my board with the pics Jason put up, and they are different :redface:

The code on my board is : JE331B53804B

Jason: I'm assuming you have an ECU for a manual trannie there?

Yes the pics i put up were for a TJ manual ECU, i just noticed the chip has a different number between the auto one you have put up and the manual one that i put up. The manual chip number is MH8206F your auto one seems to have MH8305F written on it.

Simon stated in a pm to me sumthing along the line that the guys in the USA can reflash the "MH8206F" chip. Hopefully simon can look at ur pics and ill try and work it out with the yanks with the software.

guys

the chap in the usa got back to me last night

"

I am not sure about the auto or manual, since I don't have these ECU's here.
Also you can order an interface cable thru us at www.mynesperformance.com and we will ship it to you. When the software is release, you would be able to download it for free off our website. The chip MH8206F, our software will work!"



so - this will make piggy back ecu's semi obsolete!

the factory ecu is a very good unit (as are the old delco boxes in various holdens).

i can see a bulk order of cables comming up!

anyone in melb wasnt to chat abt - pm me

rgds

simon

sounds cool. any idea on price

So is this the EcuTek software, or one of the others?

Hmm - the plot gets thick :)

If these guys in the US can re-flash the Evo ECU's, I'm starting to think it's going to work on the Magnas. Chances are the Evo's are encrypted too.

The website posted above shows this pic (http://www.mynesperformance.com/shop/images/productimages/cable-ecu.jpg) of an Evo ECU, which looks very very similar to the TJ ECU pics posted by Jason.

The connector on the right of the pic shown also looks very OBD-II ish to me. Anyone?

I'm doing some reading around about the MH8206F chip - which seems to be an interface of some type.

I'll post back as I learn more.

-Dan

Well that sounds promising since I've got a TH manual unit in my own car, so it might also use the MH8206F, which means I won't need to swap out the ECU now :D

If these guys in the US can re-flash the Evo ECU's, I'm starting to think it's going to work on the Magnas.

I had that very same thought a few weeks back, but never followed it through. It makes some sense to think that MMC globally follow some kind of strategy for all their engine management systems, given that the ECU wiring harness is the same, the Evo uses the same MAF sensor, etc - but on the other hand, the Evo is a very different car. 2 less cylinders and a turbo for a start.

I'll be pleased if it does work, and will have to seriously look at ditching my E6X and returning to factory management.

I've been looking for a while for other models that might use the same ECU as ours, namely the FTO's and Eclipse's, but I never thought about checking out what ECU the EVO's used because of the same reasons, the engine in those things are so different to ours.


It looks like they may be using OpenECU as a development tool. This could be interesting.

Doing more reading - but now I have to do work.

The MH8206F is just a microcontroller (like a PIC) - 200MHz, some RAM and an EPROM.

This makes me think even more that it's the same in the Evos and Eclipse. Mitsu simply have different firmware they flash onto the chip for different cars - but my guess is the hardware is nearly identical.

OpenECU does look very very interesting.

-Dan

Been reading more and more...

IT CAN BE DONE!

I'm going to MRT Performance (whom are probably the biggest ECUTek dealer in Australia) in about a week or two. I'll have a word with the ECUTek techies there.

If all it is is a microcontroller with RAM and EEPROM, once the initial coding has been cracked I don't see any reason why it couldn't be reprogrammed the same as a PIC... Just take some time to crack I would assume....

I'm willing to be a guinnie pig with my TJ II, might have to bring it to the Adelaide dealer and see what they have to say.

OK has anyone got any rough pricing for ECUTEK

i got a few quotes around $1500-$2000 so NO cheaper than running piggyback system

Did they definately confirm that it will work?

Also, for that money - what do you get? ie cable and software to be able to flash yourself at will - or only a one time flash?

-Dan

wicked!

I posted on openecu.org about our ECU to see what support they have...
reply below.



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


So the software to read/flash and modify roms is all totally free (open source) and the cable is $90US.
If my TE supported OBD II I'd buy this for sure. Any one else?

-Dan

hell yeah i would buy

no not yet

im going in on monday/tuesday to have it check

all they are doing is plugging it in and see if they can read the ECU and do a few checks, if so they are going to download the current maps then send it to the UK and wait for a re-tuned map and see how it goes, if all go well they will tune from there workshop

i asked what i got for the $1500 they said nothing BUT the license for the ECUTEK software on my ECU, no cable, no other software, nothing, 1 time only

on MRT website they have 3 different maps for the WRX and EVOs they charge there base price of $1400 i think that gets you the base map (more power than stock i guess) and if u wanted another map at a later date u pay approx. $200 for a reflash

so pricing is a bit steep

no not yet, im going in on monday/tuesday to have it check


Looking forward to the results alot mate!



so pricing is a bit steep

I would say that depends on the performance. if they could get 20kw from a new map - maybe its worth it bang for buck wise.

Something I've been reading on the openecu forums is that once you've had ecutek flash your car, you'll never use any other software again. They lock it down by changing the bootloader so you can't read or flash it with any other software other than ecutek.
Just FYI.

I'm going to buy an openecu calble tomorrow and will post the day it arrives.

-Dan

That is a huge IF.

and don't try to tell me it's possible because stock EVO's are getting 20kW out of a tune. Turbo cars in general are very responsive to such tuning (hell - I know a bloke who claims to have tuned 45kW into his modified XR6T with a piggyback system), I would imagine this would be especially true for Japanese performance cars, most of which are grossly de-tuned to reach the 'gentlemens agreement' of 206kW.

i have ewmailed them the other pics of the chip that was posted (thanks to Jason and the other chap)


the software will be free, cable has to be bought .. .

would suggest that there would be minor gains from a std motor - 5-8 kw at the most......

this would be due to

getting closer to max power lambda (12.7 - 12.9 afr) compared to 12.1 approx - misti appear to have set the car up rich under WOT and full load, probably to try and keep the chamber, ex valves cooler?????? - hopefully saomeone from mitsi can let us know????


i will let people know ASAP as they get back to me re manual/auto chip's

simon

That is a huge IF.

Sure, I like to think in extreme cases.

It helps me put a scale on things. Instead of just saying "No way would I ever pay $1500 for an ecu tune" I can look at it and say, well , maybe there are massive power increases to be had so maybe it is worth it.

Of corse, i never say how likely maybe is.

-Dan

For the average joe who throws in a panel filter and some extractors, you will be unlikely to get a decent return on the extra $$ spent on the ECUTek tune up. But if you're looking at doing something like myself or Jason have done, or some hard core turbo conversion, the extra convenience of keeping your factory ECU and all of its niceties is almost certainly worth the additional expense.

Couldnt agree with you more. :D

Im so glad i have no need for a aftermarket ECU, cos my car is really like a stocker to drive around town (within reason of course) and i still get really good fuel economy on a long trip.

I would think that the reason why they have a 12.1 afr is probably due to detonation. If you're using premium then you can run the leaner ratio as detonation is much less likely to occur. But from the factory mitsu would assume that most people will run their car on the normal unleaded, so the fuel map has to be set up for that.

detonation is :"the uncontrolled ingnition of the air -fuel mixture" - usually as a result of very high cylinder pressures, and is different to "pre-ignition"

lean in AFR the other way . .. .above stoich of 14.2 +/- .. . . .

lambda = 12.7 - 12.9 is the "normal" max power range

the ignition map is quite flat at WOT and load (MAF) - implying they (mitsi) didnt deem it nessecary to pull ignition timming out of the thing to reduce this tendancy . .. . .

you CAN run a high comp engine (say 10.5 - 11.0 :1 CR) on crap fuel (89 - 91 RON) and not have them ping (or detonate).....

9.0:1 CR is not going to generate that high a cylinder pressures that this will be an issue that 2-4 RON points is going to make any difference .. .


hopefully someone from mitsi can confirm that the factory engerneers set the car up deliberatly rich and the reaons why (cooling cat converters is usual reason......), would be nice to know why....

simon

Others have posted pre and post tune dynos showing a stock WOT AFR in the 10:1 range which is just crazy for a stock car. My car on the other hand was lucky to hit 12.5:1 at WOT bog stock. Mind you, this was run in hot (30+C temps) at low atmospheric pressure (high above sea level). Perhaps the factory conservativeness is to work around the different conditions in different parts of the country.

Mind you.. the ECU may have a pressure compensation map.. have to wait for Jason to respond to this one. My Haltech certainly does.

FWIW, my engine is running quite high compression. At least 11:1. Ignition advance is actually a problem at these levels. The guy tuning my engine couldn't advance the ignition very far before detonation started occuring. I don't have the exact figures to hand but I can pull them out of the map and post them if you're interested. My engine was tuned on 95 RON fuel.

i chased up some SAE (society of automotive engerneers) papers from FORD .. . .

they also tend to run rich at WOT and load,

the reasons stated in the papers were

to cool the catalytic converter

cooling ex valves

the company in the usa - now has a FREE downloadable version of the ecu-flash software on their website - see early posts (mylesperformance.com)

the following may be of interest

http://forums.evolutionm.net/showthread.php?t=202422

for those interested - the software converts hex-decimal into numbers, and then (if anything is edited) converts back to Hex .. . for those that have used a delco box - this is how it used to be done (in tyhe old days)

confirms the following:

mitsi map's are loaction speciofic,

can edit mail fuel/ign tables/ open & closed loop tables/ idle/rpm limits etc

for what it is - i found it to be a very thourough effort!!!!!

on the evo forum in us - looks like it works fine .. . . . .
