Ok just swaped a jdm b18c into a 92 integra rs, and the vtec silenoid is getting constant power at idle? if i let it warm up with it unplug then plug it back in it idles fine, possible bad ecu? anyone else run into this one before?

i was playin with my b20 vtec teg when i first got it started, adn the idle didnt change under vtec. I know vtec was in because for now it has to be hotwired to work at all.

eh this one sure did have a bad idle with it on, either way it turned out to be that the ecu was for a Automatic which has a different ECU pinout then the manual p72 ecu.
