Ecu Hardware Modifications

I would be very interested in seeing these BDM diagrams, especially for the P12. I can tell you with 100% certainty that the BDM pin locations are different for the two boards, as I have compared the two boards and they are different. I have been unsuccessful in finding a BDM diagram for the P12.
An image showing you where to connect your BDM interface to a PCM. https://wikipedia.org/wiki/Background_d ... _interface
Have you read the FAQ? For lots of information and links to significant threads see here: viewtopic.php?f=7&t=1396

Cool, thanks Antus!
Sounds similar to debugWIRE on the AVR micros. Sometimes I get lost in all the TLA's.
