I just got some examples of the DS89C450 in my hands. These 8051/52 clones are impressivly fast. Around 10 times faster than a standard 8051 at the same clock...
... The ECU is a ML3.1 Motronic as used in the Porsche 911,944 and 944 Turbo. The schematic should be available in the files section. Hardware does not seems...
The schematic is similar to the ones in the file section, but they are not the same. Jim and I traced some routes with a meter and we could not find a ...
Mine is a 944S so it is different than regular 944 and different from 951 (944 turbo) also. ... From: George To: BoschDME@yahoogroups.com Sent: Sunday, July...
... Some assignments of the ports are wrong in the schematic. The serial line circuit possibly too. But that does not affect the problem of 'in- code-timing'...
Very interesting ! I quickly read the datasheet and didn't understand if the ALE pin can behave like before (to feed ADC) while the core is running 10 times...

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...

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...
