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. ...
... I can not get this file. Give me your bin, I'll find the address. What's the goal of Autothority.bin ? All the bins are different. ... Mine :) I either...
My 3D plot was measured on a 2L 8s 147HP Alfa engine. http://apavlov.club.fr/alfa75/motro.html ML4.1 is close to ML3.1 in main calculations. The abs 'load'...
... I was just wondering that there is a constant scaleing factor for the whole curve to let it fit to the physical values. I want to replace the AFM with a...
Alexis: BIN file attached. I am converting from the vane air door (VAF) to a 0-5V Ford Mustang MAF sensor. To do this right, I need to know where the...
Mark: Wow. That was quick. What did you use to find it? Also, my ECU part number is 0 261 200 080 but the Porsche number is the same as you said below....
I'd like to point at an important detail I discovered last week. While I was playing with the maps (I use the Bosch map access code) I discovered their code...

... Does not help in the moment. My actual problem is the idle stabiliser. The MAF is not read often enough. ;-( ... ok ... ok ... ok I wrote an interface to...
... part number is 0 261 200 080 but the Porsche number is the same as you said below. That transfer function your point out is to convert from air density...

... Yes. It runs. But not perfectly. The MAF is very sensible and the AFM sample frequency is to low. ... In the ML3.1 for the 944 Turbo it is just 88 Hz. ... ...
... That looks interesting. The M2.1 seems to have a very similar table handling like to ML3.1 - but with support of multiple table sets. And there are a lot...
