VATS Questions
 

First let me say hello since I am new to the forums.

Some background info:
1983 Camaro Z/28, 1987 IROC 5.0l TPI Engine, Aftermarket TPI Wiring harness, Engine converted from MAF to 90-92 Speed Density system, ECM #1227730 EPROM #16163139

Since the body is a 1983, I have no wiring from the ignition cylinder for VATS, I have no wiring coming from the door lock cylinders for VATS, I have no VATS module or any other wiring. I know the stock EPROM comes with the VATS enabled. I am going to double check the wiring harness, but if I remember right from when I put it in, there is no wiring for the VATS.

Questions:

1. If the ECM/EPROM has nothing to communicate to or from, is the VATS a factor? I hate to have to buy all kinds of stuff just to bypass the VATS (I'm on a tight budget here).

2. Do I need to have the stock Eprom reprogrammed to have the VATS disabled to avoid all the problems with VATS?

3. If there is no associated wiring for the wiring, can I just ground the starter enable relay and not have to worry about the VATS on the eprom?

I would really like to know before I plug in a 210 dollar eprom and try to start the car and possibly damage the eprom.

Thanks for your time and input on this:thanks:

Quick update: I double checked the TPI harness, the 32 pin green ecm connector has no wiring for the VATS (GF10) is empty.

You should be able to tune out the VATS. I'm running a Caprice Cop chip and the VATS is disabled. Guess the Cops are too worried about somebody stealing their car.
