I hate piggybacks so I ditched the snow controller and will use tuner studio to set up the pump control. I talked to steve and he and I are looking at which pin out to be ideal for the solid state relay to control the variable speed motor. Work in progress and right now I'm watching some ms3 pro vids about meth injex. If anyone has already done this please chime in. If not this post can serve as a ref for anyone wanting to use the ECU gn in that fashion.
