Peitro
let me add some thing to you PCM comment
GM, Ford, Toyota, Honda, Ferrari, Porsch etc.
All thier PCM are propriatary and more so copyrighted and trademarked along with assigned Intellectual property rights. Yes yes, Bosch, Delphi, Efi Technologies, Motron might manufacture the physical PCM but with the contracts they have in place and huge NDA's along with breach of contract clause. Not happening! They can be rev-engineered as in the end, it is a 0 or 1. How many 0 or 1 and in what order is the magic number but the 3.6, hell any new car does not have anything special that can not be controlled by a full fledge standalone. I should know as I have a MoTeC M800 that I swap in and out of the car all the time for fueling testing and some other stuff I work on the side. Full contorl of the DBW system, "VVTi" and CANBus communication to ISO comms.
