well i got my jdm d15b single stage vtec wired FOR vtec. wired the solenoid into A4. ive read that on the d series vtec motors you cant actually "Hear" the vtec kick in. yes...ive done searching lol. my kick in point is 4.4k...i cant feel it....does that mean thats the perfect spot for vtec? i checked the solenoid with the 12v lead trick...it clicked. i plan to wire a little light in tomorrow at the ecu so ill know if the signal is actually coming out of the ecu. im just wondering...should i be able to hear it?
