Going to break the new engine in with the factory setup first. Will be running a S4 N/A engine ported, removed aux. sleeves and the transition smoothed with the entire engine de-smogged. This is a fuel only computer so I need to figure out how to keep the factory ignition working. Its been done so I know its possible. Just a matter of finding the right person.

 

the ignition on the fc is pretty simple. the cas sends its signals to the ecu and then that fires the coils. bascially you could leave the stock ecu in there giving it power, tps, coolant temp, and the cas signal and it should work fine
