1 wire v-tec????

[JDM DA9]

I have a DA with an ls v-tec. im using an obdo ls ecu thats chipped with chrome, and had a buddy hook up my v-tec (its just the v-tec selenoid wire going to my ecu through a relay!) he sais my v-tec should engage at 4800 rpm and it doesnt! any suggestions?

I think you have to wire up a VTEC pressure switch, although some JDM heads didn't have the pressure switch.

For one, Chrome only works on OBD1. If it is OBD1, chances are the VTEC transistor is not even installed.
