Info is scarce, it definitely is lacking there. The website is not updated often and the manuals are cryptic, but once you get a handle on it, it's a very nice system.
OE LSX coils However, you can run the distributor based system if you like the mopar stuff but will need an ignition box (msd 7 etc.)
I have hooked the 2.2 tps up to it without issue. And the ais is just a GM 4 wire in the stock throttle body. I use an accufab 75mm tb on my car with the ford tps and gm ais. The BS3 wont control a PWM based idle motor.
Ask anything you like Mike, I'd be glad to help!
