hey guys, i'm having a hesitation at around 3,000 rpms. Local rx7 guru said it's probably due to me needing another ground for my ecu, i've got the plate pulled exposing the ecu, but i can't find the ground wire. Anyone that knows where I can find it please post some info.
thanks everybody, josh

 

i have an 87 tII

 

You may want to add an extra engine ground. If that doesn't help let me know.

 

Thanks for the reply,
I was wondering what you mean by engine ground. Just a ground from the engine to the frame? I put in a fuel cut defenser and boost gauge and air fuel ratio. Now my turbo is not boosting up to expectations(only 3 lbs). I read the post about putting the fcd and it says to locate the top left brown wire on the harness. But i did that. I think it is the black wire on my harness. But I am going to try grounding the black wire and if that does not work I am open to any suggestions you have. Thanks again for any help.
