Hey everyone! I just finished installing my JB4 Pinout (yes I know pinouts are dinosaurs) and I'm having an issue.

Upon car startup the RPMs start to bounce on a steady tempo from about 600 to 1100. My car is in limp mode and wont go past 23 MPH.

Any ideas on what I should do?

I'd send pictures to BMS for advisement but it's likely a pin not fully seated.

Pin out is obsolete and no longer supported. Do the PNP harness upgrade for $180.

Even if the harness was originally a JB3 harness I can swap it for $180?
