Looks like some good stuff. Has anyone ever disected or mapped out the pcm circuit board to see what pins go to what and how it translates to the sensors?

If some gifted EE and Computer Engineer could work together to make an emulator for the PCM circuit board and sensors you could pretty well map out the entire code line by line and run simulations for various sensor settings. That would be hardcore cool. Just input sensor readings and predict what changes would result with tune changes. You could really fine tune down to every last sensor reading.

We run emulators in school and it makes learning a lot faster than trying to run real life simulations and risk ruining hardware or worse in the case of cars.. an engine. I've built various computer circuits on simulators and run assembly on emulators too but I don't know enough about all that EE stuff yet to figure out the circuit board on the PCM.

I may have to buy an extra pcm someday and bring it to school with me to find some EE guys that need a challenge
