ok i have a 91 integra with a b16 swap. I just got around to wiring my ecu for vtec. I connected up the vtec solenoid to pin a8, and Im still getting a CEL for code 21(vtec solenoid). I checked wiring/connections and there are no problems with it. I disconnected the solenoid wire and connected it directly to my vtec controller, and no problems, works perfect, so I try ecu again and I still get CEL. I reset the ecu and tryed again, and It still pops up that cel light. what could be wrong? when i have it connected to ecu, and lights on, I have no vtec. PYR Chipped PR3(obd-0) also tried stock pr3 and it does the same.
