Hello, A late response: As far as I know, the output voltage of the AFM is a (natural) logarithmic function of the airflow. So in the motronic the inverse...
Hi Sander. Thanks for the input. Yes it looks like a logarithmic function. If you get the points into excel and draw them on a logarithmic base, you get a...
Hi, Does anyone have any knowledge of DME Bosch part no 0 261 200 060. I have chased all over the net, trying to gain some information of this unit. It is...

Based on the information you provided, I would say that the 060 dme is for the euro 3.5 engine. (No O2, no cat.) The 059 unit was fitted to the US 3.5's. ... ...
Thank you for that little pearl of wisdom Glenn Whitchurch P.S Something I had not thought about To: BoschDME@yahoogroups.com From: jmc1590@... Date:...
Guys, I have a chance to read a Firehawk 944S2 chip. (yes, I will post it when I have it) but I need to know if it is a 27C64 or something else. Anyone have...
... 944 ... The Chip in the M2.1 S2 Box is a 27C256. The ML3.1 Box uses a 2732 with 24 pin configuration and a 2764 with 28 pin configuration. Looking forward...

Hello, I have problem which my motronic - mixture on idle 13.8-14.1 AFR. I tried change the master fuel map in SW on engine idle and have not result - lambda...
Hi, If your lambda corrects it to 14.1 than look at your lambda, not Motronic. Or for air leaks inside exhaust. Where do you read lambda and with which kind of...
Hello one more time. I have no air leaks, it(SW) be tested on some engines. This SW is for car with catalitiń converters, rich idle. I am read lamda from...
There *is* no map that regulates this, that is why it is called closed loop. There may be a single value that the closed loop targets for. 14.1 is hardly rich...
Narrow band lambda sensors cannot control to much other than stochiometric (14.7:1) or very close to it. It looks for a switching frequency and tries to keep...
... stochiometric (14.7:1) or very close to it. It looks for a switching frequency and tries to keep it switching. Very different from wide- band. Of...
No, program it to vary on 14.7, that should work. If that doesn't work, it's in the code of the motronic, not in your original lambda probes. Faking wrong...
Hi, I've already given you my opinion, your only chance is to disassemble. Another point is that Audi have always used special Motronics. Even when based on...
Guys, Has anyone ever seen a 16K chip in a 944S2 DME box?? I read it several ways and as a 32K, the top 16K is all ff. I thought these were supposed to be...
I have never seen anything else than a 27256 in a M2.1. But since the whole code is in the chip, it is possible to shrink it into the lower 16k. You may place...
... What is the Bosch number on the chip? It will start with B57xxx You can look up the number to determine what type of EPROM is in there. Mark D'Sylva...
Hi Mike, Your 944S2FCS.BIN is the first half of chip 126735229. Your 90944S2.BIN is the second half of the code. The code has no errors except someone put it...
That looks funny... The first half is 1267356229 code. The second half is 1267356132 code. Nothing modified so far, but the images are from two different ...
HI all, It is not a joke, just my bumbling chip reading. I do not mean to mislead anyone. So just so I can get it straight, the 944S2 chips are 32K size...
