Is there another strategy or OS that works with these cars that will get rid of the 7500rpm limit? I applied the rev limit patch, rescaled every table I can find that should have any remote importance, tried raising rev limit settings in 100 rpm increments, dialed in the speedometer settings and it still cuts at 7450-7500rpm. It sounds like the car is slowly dropping injectors one at a time and is anticipating as low as 7150rpm, nothing in the logger changes when the limit occurs other than IDC drops. Car has a CJ manifold and supporting parts to rev and power is still climbing on the dyno.
The attached file was last effort to get past the limiter even disabling fuel/spark cut torque ratios and moving limiter settings as high as 10,000 but had zero affect on anything which I found odd..
Maybe I'm missing something. Tune still needs work and I'll be setting things back to normal ranges.
