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!!!!!
no other effect on the car. but if you build your 1zz (turbo or NA ), or even just put in stronger valves and valve springs (MWR equipment), you'll be able to rev past the 6850 fuel cutoff
not yet, I found it this morning, and I have an email into MWR about how safe this would be, because they have a huge Turbo MRS that they said they rev to like 8300 rpm!!!, so when they email me back I'll know better
