Help! 6500 rpm fuel cut off on a GSR engine
Hi, I have a 98 Integra RS with a GSR motor.
I just swapped the P75 stock ECU with P72 today, hoping to get more HP and higher fuel cut off.
But now my car runs really sluggish and the fuel cut off kicks in at 6500 rpm, which is even lower than it did on P75 at around 7k rpm.
I tried resetting the ECU but it had no effect.
Help!

- VTEC solenoid valve

Is it throwing a check-engine light?
