VATS bypass.....my key reads 5.91 on mulitmeter....
I just went to radio shack and got my 1 key tested. It reads 5.91 on the multimeter. From here http://shbox.com/1/4th_gen_tech2.html#pass_key that puts me in the number 12 pellet code range (5798 to 6302).
Then, we made up a resistor using a 5.6K (2% var.) and (2) 200 ohm resistors to make up a total of 5.95K resistance (5950). Now, I realize this is higher than what my key reads (5910) but will it work???. They didnt have any 160 ohm resistors in store otherwise we could have made the exact, or a closer match.
What do you guys think??? I can get them to order the 160s, so thats not a problem.

In that link, the pellet range is 5798 - 6302 with the ideal reading 6040. If the actual reading of your resistors is 5950 there should be no problem.

If u have the correct size resistors and it didnt work dont worry about it yet. It took us a couple of tries with putting the resistors in differant ways before we got it to work.

The VATS does two things:
-enables the starter to crank
-sends a fuel enable signal to the PCM for it to allow the fuel injectors to operate
Programming the VATS out of the PCM only remedies/bypasses the fuel enable for the injectors.

Hey guys,
I am doing a lot of learning about the LT1 so sorry if this is the wrong place to ask (should I start a new thread for this?)....
I have taken a 94 LT1 from a Caprice (computer and all) that was a police cruiser and will be putting it in an 86 IROC. It used the round key for everything (door, trunk, ignition). Is it safe to assume that a fleet vehicle doesn't use VATS? Or do I need to learn about VATS also and do this resistor mod?
Thanks for teaching me,
Jim

I tried bypassing my VATS with the resistor mod, but my security light still stayed on.
Another way to bypass the vats is to jump (splice) the yellow and purple wire together in this diagram - http://shbox.com/1/pass_key.jpg then have the fuel shutoff tuned out of your PCM.
This completely bypasses the VATS without messing around with resistors.

Then what's the point of that? It's like saying, "Hey, now you can flip this light switch, but it still won't light up the room" If you can't run it, then why start it?
