951 DME Schematic
I tried search but didnt come up with anything. Wondering if anyone has a DME schematic for a late model 944 Turbo. I have an 89 turbo.
The issue I am having it that I am converting to turbo cup chips by copying a set. My father who is an electronic engineer seems to think that the chip may be a custom chip made by Bosch that has custom pinouts?? Not sure what that means. Anyone have any insight if it needs a custom chip or if a standard 28 EPROM will work?
Thanks
Brian

Nope, it is a standard 28? pin EEPROM... what matters is the size of your file and the addressing it is stored at in the prom... as long as the base table is stored at the same address as your base chip programming, you should be GTG... try it and see if it works... I am currently running a Ostrich2 from Moates, but MIGHT eventually bun the image to a PROM to move the ostrich to my other car...
I can check when I get home tonight to see if I have the file size and starting address for a cup car, but I don't believe so.. if you have a reader just read the entire chip as a larger chip (try 128K to start) it will read ALL teh addresses on the chip, and let you know where the data starts, then when you burn the new chip, just make sure the immage starts at the same starting address...

I have schematics somewhere I'll look tomorrow.
You might find this site interesting especially the DME sections

sorry the only schematic I have exceeds the forum limit by 150kb .pdf
