Title: Re: help start mapping Post by: TurboWarrior on July 03, 2015, 02:21:36 AM I too is the in the same boat mate, To power the me3.8.3 you would need the following (this is my setup) a power supply unit I used the one out of my old computer, a MPPS lead (ebay special) and some sort of crocodile clips.
Note: If you was to use an old power supply unit (PSU) you would need to jump the actual unit on most PSU it's the Green and black wire touching to actually power the PSU up I've posted the ME3.8.3 diagram That's all I have so far mate Title: Re: help start mapping Post by: TurboWarrior on July 03, 2015, 02:24:12 AM Sorry wrong Diagram ???
Correct one below Title: Re: help start mapping Post by: turboat on July 03, 2015, 04:56:12 AM m3.8.3 is a bit a pain because you cannot read it over odb. Some ecu's you can write over odb, it depends what revision they are.
See this threadhttp://nefariousmotorsports.com/forum/index.php?topic=8568.0title= there is a big thread on m3.8.3 tuning, search and you'll find it. Title: Re: help start mapping Post by: Ga3T on July 03, 2015, 05:48:24 AM thanks for this info
so do i need to de solder or just to remove the ecu and just connect to this pins? if i need to de solder, what type is the chip as i have programming tool from my robot project thats uses a51c89 chip.

Typically M383 uses AM29F200 PSOP44 flash eeproms. You can desolder it to take OEM file, or you can check it using ID procedure with MPPS and look for OEM file in the net.

Title: Re: help start mapping Post by: tjwasiak on July 04, 2015, 06:36:07 AM The one you prefer. It does not matter as long as you are able to apply changes properly and then to recalculate checksum.
Title: Re: help start mapping Post by: Ga3T on July 04, 2015, 07:33:55 AM Which one do you prefer its just i dony know any
Title: Re: help start mapping Post by: tjwasiak on July 04, 2015, 08:56:31 AM If you want to stay legal and do not spend huge money on software your options are pretty limited - TunerPro or just any free hex editor. Checksum could be solved also using free tools but it depends on which exact ECU are we talking about.
