I have a running issue with my ls and I was trying to troubleshoot a slight hesitation or miss that I can hear when I rev the car. It's a standalone harness and then a 0411 Ecu. I hooked up hptuners scanner and tried to disable injectors one at a time but I have found that they don't correspond to the the cylinder number.
C1 is injector 8, C2 is I5, C3 is I1, C4 is I2, C5 is I3, C6 is I4, C7 is I6, and C8 is I7...... Basically when I disconnected the cylinder 1 injector clip I had to disable injector 8 on hptuners scanner for it to actually turn off. I have a little noid light that I use to watch each injector turn off one at a time.
I then checked continuity from the injector wire to the correct Ecu pin and they are correct. Injector 1 goes to injector control 1 and so on...
I'm not really sure what else to check at this point. Can I change the injector assignment in hptuners or does anyone have any idea what might be going on?
