i wouldnt drive your car like this, this can just mess up your motor, since your not running the right ecu for it.

yeah think about it. ECU waiting for signal that VTEC is engaged.. but never gets it. So ECU says "Somethings wrong!" and stops it there. up until VTEC engaging, or beginning to, the engine is running fine. After that point the ECU is protecting the engine, because it thinks that you have a VTEC head thats malfunctioning somewhere.

Rep Power: 273 there is a vtec controller that does that but its useless if you car aint running right to begin with.... it only works as a bypass if you have a dx/lx ecu running an ex motor.. then you can use the controller to control it like that also
