can u use one of those proform shift lights to activate vtec? is so how, just by spliceing into the light wire?

why would you wanna do that? the ecu controls vtec so much better by adjusting the fuel and spark curves

Sinner

yea could, splice the light wire to a relay and use the relay to turn on the vtec.

you can, but you're better off with a v-tec ecu or a V-afc (is what they are trying to say ^^^)

naw im staying obd0 i dont wanna mess with all that sensor ----, im just going to buy a msd switch but was wondering if i could just use a shift light.

bambooseven

you could, but you are better off with a vafc, that way you can correct for fuel in v-tec

if you wanna ghetto rig it i think a rpm switch would be cheaper then a shift light

bambooseven

summit sells those dial shift lights now for like $30 they are pieces of ---- though, my proform one only works when it wants to.

bambooseven

I'll trade the proform light for a rpm switch if you really want the light function with it

hook it up to ur shift light then when v-tec hits it'll lean out cuz it doesn't have the ecu to add xtra spark n fuel during vtec. almost like a timebomb.. the vtec is the ticking noise u hear before BOOM! lol jk but i dont think it would be as effecient as vafc or a vtec ecu
