I am looking for the TB 4 igniton module with no rev limiter. Is the rev limite function on TB 4 an external component or is it built into the module?

I need it to be all in by 3000 rpm and provide 20 degrees of advance. This topic seems to come up a lot but I could not find any links to part numbers and advance curves.

My application is Blown 502. I tried the V6-14 module and the base had to be set at 21. Idled poorly and had bad manners.

The rev limit for all TB IV' s is an external component and not built into the modules. It only comes on blue engines.

The 20* module is a V8-HP and is no longer available. You will have to look for a used one.
