Without combing through previous threads, could you tell me what the goal is and what the current status is? Is the goal to use the existing software and...
George: I want to access maps and tunes so I can change them. I would also like to be able to change the software functionality to use a hot wire anemometer...
You are going to need a Hardware EPROM Emulator for this work. Burning EPROMs, trial and error is too slow. EPROM emulators look like EPROM to the ECU, but is...
I have a listing that compiles with one compiler (ASM51), but needs just a little more modification to compile with Phyton MCA51 compiler. My goal is to get it...
George: Wow. Sounds like some great progress. This is looking very promising now. Thanks for all your help! I am not sure if the 911 schematic is the same...
Right, I need to make sure that I have an assembly listing that can be combiled back to the original binary file. That is the starting point to making software...
I thought FRwilk's page had schematics of the 944? On schematics, be aware that there are three types of memory access in the various M2-M.31 units. Mike D....
If you find the schematics let me know. I looked on the website and I couldn't find them. Also, I need the schematics for the version of ECU that I have the ...
George: Try this page: http://svn.sourceforge.net/viewvc/*checkout*/opendme/trunk/doc/ml3.1/readme.html The old http://frwilk.com/944dme/ml31dwg.htm page is...
OK, just want to give you an update. I finally got the diassembled software compiled and running. Seems like this should have been really easy, but I fell into...
Airflow mods! Airflow mods! I have some web hacks that seem to point to the right areas for spark. I will forward them to you if you get me an email address ...
George: Fantastic! I am thinking B: find the tables and figure out units. I wish there was a way to convert it to C but maybe I just need to learn assembly....
I just uploaded it now if other people want to play with it. You'll find it's not very readable. When you diassemble code, you don't get any real variable...
I want to make sure we take notice that the work by George is exceptional. The one question I have that I have not dug into is the compatibility between the...
Dear New guy with the head full of knowlege, What is the exact version of the 8051 chip in the 3.1 DMEs???? I thought I have seen both Phillips and Siemes...
I don't actually have an ECU. This is all reversed engineered and assumed based on the ROM file. Also, I don't think it matters which manufacturer. I've used...
Could anybody tell me the CPU type that was selected for the disassembly in the files section? Some symbols are cpu specific. I would like to compare the...
... Hello Mike, sorry it took so long to respond. I don't know the exact version, but I treat it as an 8052. That's what I think it is. I don't think there ...
... I ... helpful. ... but ... there ... very ... other ... It seems to be a normal 8051. I replaced the CPU with a 8031 in several units without a problem....
I really need a Bosch/Motronic schematic for the 944. I don't think it's the same as the 911 on the site here. Does anyone have access to such info?...
There is a sechematic the earlier Motronic internal on FRwilk's website. You are correct, there are a few resistors and caps different than the 911. I put...
We recently found some schematics that match the 944S ECU (0 261 200 080) better. They are from an Opel Omega. It is the same as the 944S except the extra...

There is a provision on the Motronic cars (944 and 911) to make small adjustments to the fuel mixture (injection pulsewidth) and the ignition timing in order...
Hi, It's good to see a site like this. People starting to gather information about the motronic and it's "secrets". And especially to to reveal those...
