I can build a fairly decent F/I system but not even close on spark.. so I decided instead of bypassing and tricking sensors and still not getting enough spark advance I better learn the innards of the PCM. Little did I know what I was getting into.. ;D
Its getting too hard to find affordable old cars in good shape and of course with new cars and smog laws etc. you better be able to fine tune your setup if you want to add any goodies and pass...
So.. what are you looking to get (or give) from here?
