Maybe a tuner can help me out
I have a P28 that is setup to run a turbo B16
I had it on a turbo LS and it ran fine after we grounded the A4 wire
I now have it on another LS with the same wire grouded and it still throws a check engine code 21 for VTEC

Can somebody help me

 

are both ls the same setup? regardless that chip combo will not work on an ls. Depending on the editor, vtec can be disabled. ofcourse its looking for vtec parameters, its on a vtec chip/map and ecu. Why are you not using the correct ecu? It could possibly damage the ecu in the long run.

 

both are the same setup
It ran fine on the other car that it was in
it was in a 95 civic DX with an LS swap
now it is in a 94 Integra LS
thats all the same stuff
I just cant figure it out
