IT INVOLVES 2 THINGS WHICH I WONT EVER DO .. EVER
CUT ground wire to dist connect it to str8 to rpm signal wire on S-afc .im not very good with electrical so you might still have to coonect to wire goin to ecu to something.
your rpms should still show on s-afc but your cluster nor your ecu wont know whats goin on..
this is based on theory and i would not try it EVER.
IF THE ECU doesnt know what rpms your at it shouldnt have a limiter an this would be based tried on b13,p10 wiring harness.. again.. dont fukin do this.. call CALUM its dirt cheap with fukin quality work. dont be gay. an risk lossing hp due to chopped harness.
