vtec issue please help.
ok so i did a gsr swap in my Eg hatch and now im having vtec issues. I am getting Cel 21 thats t6he spool valve also knowen as the vtec solenoid. I did all my continuity checks and everything is good. I am running a chipped P06 that i got done by Shawn at Ramey built so i know thats good.i wired everything up to the right spots on the ecu harness.
I am not getting any power to the oil pressure side of the vtec switch wich is good but as soon as i turn the key on im getting 12v to the soleniod is this right? Some one help me out here im running out of ideas

If I remember, the ECU sources 12V to the solenoid, and the solenoid is ground referenced, so you shouldn't have anything on that wire until VTEC engages.

Re: vtec issue please help.
So you put a known-good ECU in the car, and it works but you get a solenoid CEL. Therefore you have a solenoid (or solenoid wiring) problem. I'm assuming the ECU is doing fault detection when it tries to activate the solenoid, which many/most ECUs do.
Anyway, it sounds like you know where to look.
