Icon9 H22a1 rev problem

I have a slightly built h22a1 with a chipped p28 ecu and the rev limit was set at 7100 on the ecu and it worked for a while now the revs are cutting out at 6200. My vtec engages at 4200. When the car is driving for like 20 minutes I get a CEL and when I turn my car off and back on again it turns off for like 5 mins. Can you diagnose the issue while the car is on? Obd1 so I'm using a paperclip in the diagnoser.

Re: H22a1 rev problem

And my tach is not wrong. I tuned the ecu to crack at 4200. The 6200 rev limit is fun in the rain because it just bounces super easy but I feel like I'm missing out on some power. Should I just take my ecu in to get reprogrammed or is it something mechanical.

Is VTEC engaging when it hits the limiter at 6200? I had a plugged up VTEC solenoid screen once and it stopped my VTEC from operating. When it did that the car would hit the rev limiter around 6200.

Nope. I plugged In a new gauge cluster and it fixed my problem. Vtec engages at 5500 and rev cut at 8200-8400
