I just put a z6 head on my d15b7. I have the vtec wired and set up correctly with a p28 ecu. But when I hit 6k rpms i throw up a check engine light suggesting that im not cracking v. Is there a sensor or something im missing making me not get oil to my vtec solenoid??
Thanks!

 

Seems obvious. Pull the code for the CEL and stop guessing.

Quick question, did you remove the oil jet in your block?
