jdm p30 ecu, chipped but still hits speed limiter.

got chipped and tuned, speed limiter was disabled but still tops out at 120mph. wont let me go any faster than that.the rpm in fifth gear at 120mph are at 7000.
ive heard that the jdm p30 ecu is different than the usdm obd1 p28.

i got tuned with crome pro fyi.
someone give me a lil insight please.

No kidding, they are 2 different ecu's!!

P28 is for a SOHC 1.6L vtec

P30 is for a DOHC 1.6L vtec B16A

The difference between jsm and usdm is usually the fact the jdm ecu "has" the speed governor

Damn, why would you want to go faster than 120mph in fifth gear? Trying to reach the land speed record? I hope you have good tires and are doing this at a race track.
