I am putting a ls3 427 in my 69 camaro and would like to know if it would be possible to use the GM VATS system from a 93 camaro, it is a stand alone module. it does not have to cut off the injectors like original, I was thinking it could cut the power to the MAST motorsports e90 ECM so it would not start. the research I have done i come up with the vats system sends out a pulse width modulated signal to the original gm emc to turn off the injector pulse, would this work to turn on or off a relay that connects power to the ecm to turn it on and off. I like the factory system and do not want to put a A/M **** alarm on the car. any help would be great

 

You should be able to change the vats signal the PCM is expecting from serial to PWM and use the old style Vats

 

Any other help please

 

Try posting this in the hybrids section. There's probably more experience over there doing this.
