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...
Hi everyone, I'm new here. Alpa (that you'll find in the collection) it's me :) So I can help if you have questions I'd like to find mark944turbo, I lost his...
Hi, I've just subscribed. May be some of us know me, 'Alpa' on many forums. Some usefull infos at my page: http://apavlov.club.fr/motronic/motronic.html I'm...
... Hi Alpa - great to have you here. Your algorithm for the AFM curve helped me a lot - thanks! Do you have an idea how the curve is scaled? I tested it on...
No idea about scale. The internal calculations use 2 or 3 bytes values. This value is corrected with the air temp and pressure to get the mass flow and then...
... I did some measurement with AFMs to get the flow curve. I used a well known MAF with a mass/volume conversion to measure the air flow (green). Takeing the...
Great stuff! Do you know where this map is in the 1987 944S BIN file? I have several uploaded into this forum. We are working on the Autothority.bin. ...
