I have a s13 sr20det red top with a power fc.
Tuned on 740cc blitz turbo z32 maf.
I was doing some repairs and forgot to re connect the coil pack pulse.
It was cut by p/o so it was live and I believe shorted. It’s a thick black wire.
Anywho now my #3 injector is fouling causing the cylinder to not fire properly.
I swapped coils. Swapped injectors. I have coil pulse and signal to all cylinders
And injector pulse to all 4.
When doing this test I noticed #3 signal pulse from ecu was much stronger leading me to believe the injector driver is shorted and causing a fuel spray imbalance. Is it possible A’PEXi to repair this or just buy another ecu and reload my old map?
Thanks!
