i am trying to get my v-tec working i have a b18a1 with a 99 si head on it. I need to know what ecu pins to hook the vtec solenoid,vtec oil pressure sensor, and the knock sensor on a pr4 ecu any help would be nice thanks guys and girls

 

I dont think you can run vtec on a pr4 ecu...isnt that an ls ecu?

 

look up LS VTEC conversions, they tell you how to wire your vtec head for VTEC.

 

you will need a pr3 to run vtec but i would suggest running ODB1 and getting it tuned cause the fuel maps are different..
