Hey guys, just about to chuck in a 1j into my cressida. Single turbo, auto. I have a 1j engine loom and ecu just need to know how to run it all. Do I splice the 7m loom and 1j loom? Can the 1j ecu be tuned to run the gt35/40 at a higher boost or do I need to run a piggy back setup on the 1j ecu? Dont really want to go full aftermarket ecu yet. Cheers.
