I added both CPU and Eprom datasheets in the file section ... I read 80c537, 80c517 and 80c517A datasheets and the RESET pin is pin number 10. Are you talking...
Get a spare ECU if you want to "play" with it. your daily car won't run otherwise. Also, make certain you know how to deal with the IMMO box if you are going...
8051 and its derivates that come in a DIP40 package have pin 31 asgined as "EA-". If this pin is grounded the internal 4k ROM of the microcontroller is not...
... Don't expect a lot. It's like if you were saying: I don't understand what's inside an engine but I'm working with guys who design them so I'll be able to ...
I like your way if thinking, I agree with you. Anyway, thanks to all of you. Now, I know what I have to do and I will email you when it will be done. Bye ...
... It would be great to keep us updated. To my information the B58468 device is a SAB80C517. The tablegroup selection is done by the DPSEL SFR (92H). You...
Hello, new here and I am wondering if anyone knows what determines which timing map is used when? ie does the TPS solely determine when Its switches at 60% or...
what car, what ecu exactly? Don't mess with zener diodes, change the maps. If the ECU doesn't work out, either reprogram it or use a megasquirt or another...

Anyone know the FQS ignition retard values for the 944S & 944S2? I have fuel values on the table, still no idea what the ignition. Anyone? 944S 6274h: 80 84 7C...
Hi all, I was staring at a 944 turbo DME with the 24 pin eprom. Since it is known that the 28 pin conversion is the B700 jumper and the extra Eprom pins, I...

Guys, I need a fact check on this one. After looking at a 924S disassembly that was posted on the net, I saw references to overboost in the disassembly. That...
Hi Mike. Yes - you're right. The lower 4k are identical in all 924S, 944 and 951 ML3.1 boxes. Including 968TS. You can easily identify non-turbo systems by the...
