VATS bypass module is intended for use when installing a GM engine equipped with VATS (Vehicle Anti-Theft System) into a vehicle missing the BCM (Body Control Module), when resistor type bypasses just wont work, or for use with remote starting applications involving stock vehicles equipped with VATS. Our VATS bypass will also work to bypass failing VATS systems.
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. Normally it costs between $150 and $300 to have this feature deleted from the PCM. By using our module you will accomplish the same function for less and you won't have to ship your PCM/ECM to have it reprogrammed.
Module will work with:
GM 'F' body type vehicles from 1989 and up
93 and up LT1 with some exceptions after 95
98 and up LS1 with some exceptions
All VATS equipped GM (Buick, Chevy, Oldsmobile and Pontiac) vehicles from 89 to 02 that originally had the black resistor pellet in the metal part of the ignition key
All VATS equipped GM vehicles from 89 to 95, some engines made from 89 to 93
All VATS equipped GM vehicles from 89 to 02 that has a wire to the PCM labeled VATS, Fuel enable or Circuit 229
Module is a simple four-wire interface (power, ground, standard signal and 30Hz signal) and if installed with a detachable connector, it can be removed to enable the factory anti-theft system to protect your car over night or at the car show. You can't do that if you programmed that feature out of your PCM/ECM.
This module comes equipped with a status LED that indicates that it is functioning.
Dual Frequency VATS Bypass generates both Standard VATS Signal as well as the 30Hz Signal all in one module.
Other Features include:
Microcontroller based for reliability and accuracy
Specially designed circuit board with 14bit processor.
Works on any 12V Ignition or Accessory wire (operates from 7V to 24V)
Reverse voltage protection in the event of incorrect power connections
Short circuit protection on all outputs to 12V or ground
Dual frequency: Standard VATS and 30Hz VATS
Light weight (.5oz)
Small package (0.8in by 0.5in by 0.12in)
