MOTEC is your answer they've already done the work for this engine using their system.
M5_SMG said:I'm doing an engine transplant and am considering dumping the factory electronics (DME) in favor of a full aftermarket computer. Makes things simpler in some ways (ditch the MAFS, EWS etc.), but of course more difficult with having to setup all the base parameters (cold start, idle etc.). Doing the actual AF tuning isn't too much of a worry, but the cam timing is. Does anyone have a lookup table of the actual VANOS cam adjustments? Or does anyone have a piggy-back ECU capable of logging this information? Any possible info. from OBD?
This is my biggest hesitation with ditching the stock ECU as I'd rather have a base to start with the cam timing rather than doing it all from scratch.
If anyone is wondering why I don't hook-up the aftermarket ECU to the factory DME and log the cam positions, its because getting everything to work in stock form would require EWS, DME, I believe instrument cluster etc. which I don't have. In that case, I might as well go with the stock setup. Any info. or nudges in the right direction would be helpful. Thanks! :thumbsup:
