i'm doing a mini me with a y8 head but how do i get the v-tec to work?

 

theres two ways. one is ghetto, the other is the right way.

running obd0 youll need an rpm activated switch that spools the soleniod at whatever rpm you want, but it will not adjust the fuel maps so your goign to lean out everytime you hit vtec, this is not good.

convert the car to obd1 and use the p30 ecu thats meant for that head, and a 150$ jumper harness obd0->obd1 and the vtec will come on and give proper fuel, plus long term there is more tuning options for an obd1 car.

search on here for "mini me" with archive checked

theres tons of threads about it.

 

There are 3 good ones in my thread

ok i have the civic si body so is that obd1 or obd0?

 

All 88-91s are OBD-0

 

KNOW ANYONE WITH A P30 ECU?

 

if you want to save money you could get a chipped obd0 ECU (i have one) with a fuel and timing map set at a certain RPM and get a rpm activated switch that will give voltage to the vtec solenoid at that specific RPM.
