FWIW, this is a supercharged gas motor (3.6l pentastar). The TVS supercharger is water/air intercooled and bolted to a stock motor. It peaks at ~9.5psi @ redline.
I plan to run pure water ~80% of the time and occasionally swap out the jet(s) to run 50/50.
thanks!
edit: this is a non-DI motor.

The blue wire of the green harness has two functions with one single signal:
1. hi/lo crossover failsafe
2. trims flow
I believe you are referring to the failsafe. In this case, WBO" signal will be a better bet. At the same time, you can active the flow trim/supplement based on the AFR. (this option requires some soldering work).
