94 cx with jdm b18c bla bla bla, anyway vtec is definatly working, i can hear it pop on, it runs great, but when i hit vtec the cel comes on, it still runs ok, but if i turn it off and turn it back on, no cel until i hit vtec again, and no i'm no abusing it, i take it real easy into vtec no wot or anything, then when the cel comes on i slow it down, could it have anything to do with my ghetto rigged wiring, i have wires sticking in the pin holes until i get some real pins, the only ones i have rigged are the vtec pressure swtich, vtec solenoid, and the knock sensor, but i've heard of other people doing it that way with no problem, but i dunno, any ideas?

 

ok it does not come on when i hit vtec, i comes on when i SHOULD hit the secondary runners, but i have a skunk2 manifold, could that be the problem, if is what can i do to remedy the situation?

 

Well, can you pull a code? Probably has to do with the pressure switch, since it comes on when you hit vtec.

 

Nevermind, probably the IAb it's looking for. JDM GSR right?

 

which ecu, what's the cel code?

 

i can't pull a code, it dosn't give one, once i shut it down and turn it back on the cel dosn't comeback till the iabs are supposed to come on, yes its a jdm gsr, i'm using the jdm p72, so if it is the iabs what can i do to fix it?

 

Get it, or another ECU with the right maps chipped not to look for them.

that's definitely an option, but there is no reason you can't get the code. Even if it goes away everytime you start it, it'll still read the code. Either you didn't jump it right, or your ecu is messed up.

 

The ECU stores a code, even though the CEL goes away. A scanner that plugs into the OBD port should be able to pull it.

 

if it stores the code, why can't i pull it by the jump service connector method?

 

code can be a few things.Vtec pressure switch, vtec solenoid,or your knock sensor.
