ok im in the middle of doin the dpfi to mpfi swap in my 91 std hatchback. ive read and printed the faq out already and ive found a diff in mine to the print out. ok when your swapping ecu's it says b10 and b12 should b empty well mine has b10 empty but b12 is occupied what should i do??

 

bumpppp
plzzzzz helppp!!!!!!!

 

b12 sometimes has a wire in it. if so your fine! just one less wire to pin in that spot. cut it and run it to where the instructions say to.

c1 & c2 are cam angle and if i remember right b10 and b12 are crank.

 

ok thank you.
its extremely appreciated !!!

 

when we were doing the swap we noticed this thing bolted up to the driver side of the intake manifold in the back, its not the iacv but there is nothing on the DX harness to plug into this thing
