Since I eliminate the rev limiter of my 360 to take advantage of the ported head and exhaust and a hot cam. The engine was proved in another car and tour assurance to 7000 revs,But in this car to 6200revs are activated revs limiter (The ecu is of one b200f)

The rev limiter could be in the renix (coil unit) or you could have a dizzy with a rev limiter rotor arm fitted.

Yes you'll need another renix. Somewhere here in the forum was a list of all the renix unit numbers. Try to find that and i hope that you find what you are after.
