I am looking for a ECU upgrade mainly to raise the rev-limiter just a little. I run the car in Honda Challenge and I need just a little more RPM. Most guys simply put in the PG7 out of an 88 integra and they get a little better Fuel curve along with about 300 more RPM. I tried this but when I start the car with the PG7 it idols very rich and won't rev over 3500 RPM. Any ideas? Thanks in advance for your help.
