Any ideas for this VATS issue?
I have a 1985 Corvette which of course came with no VATS. I installed a 1986 harness, and a 165 ECU. My harness has the VATS control module and as I understand it all 165 ECUs (with Corvette chips) have VATS enabled in the PROM.
I do not have the ignition key from the car that the harness came out of. My ignition switch is not capable of reading a VATS key as it is the original '85 switch.
So, I can't do the resistor bypass because I don't know the resistor value of my VATS module. I have no key to read to find out what it is. What would be the easiest way for me to bypass the VATS system so when I am ready to fire up my car the VATS will be disabled?
thanks,

VATS does both. If the wrong value resistor is used, VATS will not close the start enable relay which interupts the current to the starter solenoid AND it sends a signal to the ECM to not exercise the injectors so a thief cannot push start the car.

IMO, the easiest solution with this is to send the prom to someone like tjwong or Alvin and have the vats disabled. I did this to my 86 basket case which I recently built...I was able to start it without dramas, and I know I will NEVER have the dreaded vats syndrome. (while the chip was being worked on, I put a spare in and found that I actually had a defective vats module!) Best $35-40 you are likely to invest in your vette...
