I just finished dropping in a obd1 GSR swap into my obd1 LS shell. I fallowed the instructions on phearable.net to rewire vtec to the ecu. I have the vtec solenoid wired to A4 and the pressure sensor wired to D6. And i still cannot get vtec to pop. The car is throwing a knock sensor code. Someone told me that the knock sensor could be the reason but at least 3 people have told me it shouldnt matter. Any help will be greatly appreciated! and repp'd.


Oil level is fine.
Car was always at operating temperature.
The car has an original obd1 GSR ecu.
The swap popped vtec fine in the car it was in b4 the LS body.
I tried replacing the solenoid with another known working one and nothing.
