VATS Module Bypass for 88-2002 Camaro & Firebird, Dual Frequency, shipping is not included, call or email for shipping.
The VATS bypass module is intended for use when installing a GM engine equipped with PASSkeyII type VATS (Vehicle Anti-Theft System) into a vehicle missing the BCM (Body Control Module). The bypass module generates the signal normally sent from the BCM to the PCM/ECM when the proper key is detected. Without this signal, the fuel injectors will not work.

This bypass module generates the 'key OK' signal normally sent from the BCM, sometimes called the VATS decoder, to the PCM/ECM when the proper key is detected. Without this signal, the fuel injectors will shut down within the first 3 seconds.
This module will work with:



* All VATS equipped GM (Buick, Chevy, Oldsmobile and Pontiac) vehicles from 86 to 02 that originally had the black resistor pellet in the metal part of the ignition key
* All VATS equipped GM vehicles from 86 to 02 that has a wire to the PCM labeled VATS, Fuel enable or Circuit 229


This module is a simple three-wire interface (power, ground, signal).

This module comes equipped with a status LED that indicates that it is functioning

 

Bump for Picture

 

Where does it plug in or do you need to hard wire it in?

 

The device gets wired to the Vats wire of the ECM, ground, and power. I added the molex connector so the box can be removed when not in use or as an extra security feature.

 

How do you set the resistance value?

 

Sounds like this actually generates the singnal instead of merely using a specific resistance to complete the circuit.

Like this: You could have the right resistor in the wires under the dash for the car to start, but it wouldn't make a difference if you didn't have a BCM in the car. It essentially fools the PCM into thinking the BCM says it has the right key, instead of the resistor telling the BCM the key is right, and then going to the PCM.

If that made any sense LOL

EDIT: Or maybe im completely wrong. =p

 

You are completely right it gives a 50hz signal to the bcm
