I have a 93 CIVIC SI just swapped in my LS/vtec swap. Im using a P28 ECU. I just had my Vtec controller installed.. Problem is.. My cluster is not working.. Ever since i got this civic Shell. Just got the motor in like 2 weeks ago.. Still havn't felt vtec. Vtec activates but no vtec. Every thing has been Triple checked. Could it be that my CLuster is not working to make the VTEC not engage? How could i fix my cluster Every thing is plugging in where its supposed to be. Anyone have a diagram for the cluster layout? Please help me!
