P01 or p59 crankshaft input modification
Has anyone been able to locate where the crankshaft signal is first processed in the PCM? I'd like to intercept the signal before it's processed

Which OS? I think its connected to an interrupt, you should be able to get the entry point from one of the external interrupt vectors near the start of the bin.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396

Are you asking for a location on the circuit board, or in the code?
It's pin 12 on the blue connector if that helps:

Please don't PM me with technical questions - start a thread instead, and send me a link to it. That way I can answer in public, and help other people who have the same question. Thanks!
