K i have a 98 civic hatch with an obd2 ls/vtec motor and a 97 gsr ecu. Im bearly breaking it in,so im only revving to 3500rpm. My question is, the ls bottem end dont have CKF sensors, and since im using the 97 gsr ecu which is looking for it (since gsr's do have CKF sensors)and giving me the code, is this going to effect the VTEC activation in any ways? -paul
