UPDATE
Today i've tried over 20 maps, with and without soft launch limiter and nothing. (Soft launch limiter VNMX,DNMAXH,ITNMXH,NMAX,TMOTNMX,TNMXH)
THe only one result is with soft launcher disabled, and FTOMN to 0014 with this settings:
Scalar: LaunchRPM changed from 16384 RPM (0xFFFF) to 4500 RPM (0x4650).
Scalar: RPMThreshold changed from 16384 RPM (0xFFFF) to 5500 RPM (0x55F0).
Scalar: IgnitionCutDuration changed from 1310700 (0xFFFF) to 200 (0x000A).
Scalar: AccPedalThreshold changed from 100 (0xFF) to 90 (0xE5).
Scalar: SpeedThreshold changed from 512.02 km/h (0xFFFF) to 3.30 km/h (0x01A6).
Only "pops" and little boost (8-9psi) on 4500rpm and go fast to redline. Disassemled launch.php in first post and searched for results in bin output with an hex editor and all seems to be good.
