    Have u had the wires ran to your computer for the v-tec. If not u have to run the V-tec solenoid wire which is green and yellow (one wire) to your computer. Use pin A4. V-tec oil pressure switch, light blue wire gets ran to (one wire) to pin d6. Then the black and red (one wire) gets grounded somewhere. Also if u have a knock sensor on your motor u need the prelude plug off of a harness and then u have to run the wire to pin d3. If u have already had this done then I really don't know what your problem could be.

    Is the check engine light on? It sounds like you're in limp mode...
