no more 1zz fuel cutoff

This is courtesy of c2gas. he doesn't spend much time over here, and I've been trying to get him to post how to get rid of the 1zz fuel cutoff point...Just figured I'd give him FULL CREDIT before I posted.

How to remove the rev-limiter in the 1zz -fe engine:
On the pic below change out the 16 mhz crystals to 18 mhz, and eureka...no more fuel cutoff point!!!!!

does it affect anything else in the car?? And i wouldnt see much reason for this unless someone has a fixed up engine, doing this for a stock 1zz is thumbsdown rofl

no other effect on the car. but if you build your 1zz (turbo or NA grin), or even just put in stronger valves and valve springs (MWR equipment), you'll be able to rev past the 6850 fuel cutoff
