93 motor in 93 s13
All 8 injectors firing
New KS's
Harness by JSimpson
Deleted egr and iavc
All pcv lines vented

Starts up fine every time, hits a nasty rev limiter around 4k rpms. Really fast like anti lag. Not maf limiter. Tried multiple ecu's also.

Timing? No shit, my project fired up every time to, and it was off a link....seems like the ECU is pulling timing when you rev it?

You could try pulling the TPS and see if it changes the behavior to rule that out...you check coilpack resistance?

I haven't tested coilpacks. I will try unplugging tps and see it it makes a difference, but yes ecu is doing something retarded

Yea definitely check the coilpacks. Unplug and plug each one separately to see if they are still good.
