alright i got a question for all you pros at doing the mpfi thing. I have a 90 hatch that i did the mpfi swap to last year. I think somewhere in my wiring is screwed. I have followed all the links on here i have found for the swap but now i have one question. At the ecu, pin c2 origanally had a white wire going to it. I think that white wire was for the crank angle sensor. WHen you do the mpfi swap you are suposed to put the blue/yellow wire from the dizzy in position c2. Now my question is where do you put that white wire? I think i have my wiring routed wrong because since i have done the mpfi swap the motor wont take a full 100% rev without boggin and i have been goin through distributors like gas. Any clues. I've searched and cant seem to find anyone with my same problems

 

BUMP

hey man, thanks alot. I think you just helped me figure this out. I think i acutally rode around for a year with that white wire hooked up at c2 when it should have been at b12. I dont see how the car was even running. Thanks Alot

 

B10 and B12 are your cyl pos sensor wires. So the white would go to B10 i believe and orange to B12. c1 and c2 are your crank position sensor wires.
