Just read through my last post and didn't like how it seemed to imply that this is a full on replacement for the solenoid - I don't think it is... I think it will work well on some less critical installs (like my OS .37SZ) but I think the solenoid will still be beneficial in a lot of cases.

As it is built now if the power lead is plugged into a mid stick fixed output - It strictly acts like muffler pressure - the RC range 1000 - 2000 ms can add a 20% bias either way to do simple mixture adjustment but 1500 is the fixed curve set by the program with RPM input.
