I have a 91 civic dx std with a obd1 b16a. I swapped a 94 gsr cluster into it. I have seen shit tons of how to's to do this swap. All of them are on non vtec engines. The electric vss works in conjunction with the vtec switch. I have no vtec. I tested my computer,vtec pressure switch, and vtec solenoid on my buddies car. They all work fine. Any help would be appreciated.
