Gonna venture it's for the drone valves in the exhaust?

There are two groups that will want/need this.
1. In the need category you have the C7 crowd. Some of the guys that road race are burning up the AFM valves. This has been an on going issue with no apparent proper resolution from GM. It has lead to many interesting solutions... none of which are elegant. The AFM actuators are controlled by the chassis control module so we cannot disable the codes that cause a check engine light. The CCM is looking for certain things to keep from setting codes.
2. In the want/need category you have people that want to change out their exhaust setup. Some vendors properly offer setups with AFM valves and mounts for the actuators (for more $$). Some vendors do not AFM support at all. This can exclude certain aftermarket exhaust setups. These modules will allow you to remove the valves and actuators completely with no codes.
My modules are not a simple passive circuits. If it was that simple someone would have done this over a year ago. They are active circuits that have the proper protection for the automotive power environment. I am also using the exact same connector supplier GM does (with weather seals). The final product will have the PCBs properly potted in electronics epoxy so there will never be moisture issues. I don't under design.
I'm working on the revised schematic and layout as we speak (or type) and hope to have them out the door tomorrow morning for fab.
