first off its a gsr built for turbo with ctr cams. Im using a chipped p28. I had a the vtec cels on but wired the vtec up and they r off now. i have cleaned the soleniod out and made sure the soleniod was good. I have used even my friends ecu chipped as well to make sure it wasnt the ecu. First starting the new engine but i have a map sensor cel and in the manual it says vtec relies on the map to be working so i can really used some help on getting the vtec to engage please thanks
