Hows the rev limit on EFI raised (FRST management, OFAB)

as above really

On the RST MFI, you need to change some bits in the fuel ECU, well FRST management doesn't have one so anyone know how its done ?

Anyone who's actually had it done ?

From what ive heard some chips will do it but u need solid lifters (don't actually know what they are, lol) and a balanced bottom end.
Life moves pretty fast. If you don't stop to look around once in a while, you could miss it.

surely it will be in the map?

above such and such a revs equals no igntition, above such and such more revs no igintion or fuel? or something along those lines?

thats how i thought it worked but im not 100% on it

exactly, stu will have set it in the chip.

Mik3y - that has nothing to do with it. if you are revving to certain rpm you may need to change the lifters, anti-pump should be fine to 7200 before you get valve bounce, after that you would need to get solid lifters and a cam that can suitably use solid lifters, but the rev limit is in the chip.

I'm currently running in and I have a 5k rev limit and 6.5psi boost limit, it just cuts everything out after that.
