Bypassing VATS On My 1993 Corvette LT1 (First Start!)
In this video I bypass vats on my 1993 corvette with the lt1.
NOTE: This method will work for 1986-1993 Corvettes. 1994-1995 will need an obd1 tune, and 1996 will need an obd2 tune. All years will require the theft deterrent relay (TDR) to be bypassed after disabling VATS in the PCM. This method is how to COMPLETELY remove VATS.
I explain a little information on PASS-KEY, PASS-KEY II and VATS. This is the fix for whenever the resistor trick does not work. When the theft deterrent module goes bad, this is the fix to bypass the security system. Feel free to comment and ask any questions about the VATS system as I have answers to your questions!
Also, the engine in this car is brand new with hardly any miles on it at all since the rebuild. I was not expecting it to start when it did and therefore did not spend time priming the oil pressure in the system, and the first start had some lifter tick. But after a few seconds the oil got to the entire engine and the noise went away. Also discovered another issue that was causing a rough idle at first.
