Hondata

I recently had a s100 system installed & tunned at my local hondata dealer. with the interface box and romulator pluged in the vtec ran great on but with the s100 and the the the same proram burt to eprom, the car runs the same but I have no vtec, there is no CEL showing. Any Ideas?

Are you sure there is no VTEC, or is there a possibility that it's a smooth and unnoticable transition into VTEC?

Im pretty sure there's no vtec, it was good and loud durring tuning (on the dyno) and now I hear nothing? I guess I could jack up the front of the car and rev it to vtec with no load with a test light in the vtec wire to check it, but I almost certain theres not.

well I stuck a test light in the vtec wire and there is definatly no vtec comming on at all, not sure why. Anyone have any ideas?
