you know some information on what car? engine? year? obd? are all nice things to know because just saying you blew a fuse and won't go past 5500 RPM doesn't help much

Sounds like you fried the turbo encabulator, just go over to Honda and ask for a new one, they will hook you up.

I myself have a similar problem. I have a 2000 automatic integra. I converted it to manual with a b20z and a type r lsd tranny. Car revs fine with auto ecu obd2.However I converted it to obd1 with an obd2b to obd1 harness alongside a 1995 obd1 p75 manual ecu. And now the car wont rev pass 5500. It hits 5500 but then just goes down and picks up again. The problem only persists while with in obd1?

How do I fix this?

Thanking you in advance
