So I have a 92 civic with a Ls Block Gsr Head....i have the stock wire harness and i manually wired up the vtec to a p28 ecu with Hondata..i am running a turbo setup....we just dyno'd it and i am havin a problem...the car hits vtec....but as soon as it does it throws a cel...i checked it once..it gave me code 21...we tried it on 2 diff ecu's and 2 diff hondata's...i will smash on it in 1st and it will go into vtec....go into 2nd...hit vtec...as soon as i let off it throws the cel...or i can just hit vtec in 1st gear...let off and it throws the code....i tried changing the solenoid...and i tried goin back and checkin the wires and soldering it and making sure it is all good....i still have the same problem....any idea's anyone?
