I think that there is a problem with Group N calibration for FN2 in FlashPro. My car detonates when engine enters VTEC @3800rpm. I think that it is not the same calibration which was used in Group N reflashed ECU. And it seems that there is a flat spot at 2500-3500rpm.

My mods: Toda header, Milltek sport stainless steel exhaust, Hondata heatshield gasket, FlashPro, Toda hi-power clutch/flywheel kit.

With that mods Group N Reflashed ECU worked fine.

Soon I'll make datalog and put it here.

Here is my datalog. When I press accelerator slightly during entering VTEC @3800rpm my car jerks from 3800 till 4200rpm and there is some detonation heard in exhaust system. When I press accelerator harder during entering VTEC there is no so much jerking and detonation.
Maybe you can see from datalog what is wrong?
