Hi guys, I'm familiar with the Pw0 mugen program, I believe its 4400RPM VTEC with no rev limiter. I bought an integra a month or so ago, and pulled the ECU to check things out and the chip sais mugen on it. However, VTEC still kicks in at 5100 +/- and the rev limiter is still set at 8200 RPM as I found out at the last solo. Any thoughts? Are there slight variations?
