Rev Cut is there for a reason... so, unless if u have rebuild ur engine... it's best to leave it.

i know..but i have do some modified to this engine...i have change higher compression piston,porting.metal gasket...
is more powerful than standard...
so the rev cut come too early..
so i choose to replace the chip to maybe 8500-9000rpm...
so does it got any chip for this ECU....?

answer is NO...since this is a Step 0 ECU which used Co2 adjuster...cannot be rechip. Not extension slot...if Step 1 ECU can...but that's only available in SGTi which used o2 Sensor

If i am not mistaken, your rev cut is at 8500 RPM which after redline...

Alternative you may wanna go for standalone ECU like Haltech
