s13-4 nightmare

[aga]

wassup guys! i just bought a 200sx (s13) with a s1 s14 engine... in not running condition. the guy was selling it with no turbo, and forged engine with zero miles, an abandoned project. i flew 500kms, put it together with a friend with a gt2860, and fired it up after we adjusted cam timing etc. it fired, but was running uber rich.

the guy has a mine's ecu and a z32 maf and was saying that it was running ok but i'm not buying it. :facepalm:

anyway i bought an s14 power fc , plugged it in hoping that i'll tune it and select the z32 maf and we are go but the ecu didnt even have power. after a lot of looking around we found out that the wiring was a hell of a mess. as we speak my mate is tearing apart the loom and rebuilding it from the start.

so what is the question . i believe i have the right power fc, the engine is a blacktop with the big plug , and on the side of the power fc ,on the serial number it says PFCS14blahblah... i cannot understand how the car ran with the mine's ecu and the fc didnt even have power... any ideas? am i doing the right thing redoing the loom? (i guess you would agree ,if you saw the rest of the fabrication done on the rest of the car :cj: )
