I have an exhaust cut out that is vacuum controlled and snaps open using a vacuum solenoid activated by a switch on the throttle. I'd like to have the ECM control it so that is doesn't open until 4000 RPM. I've got a healthy cam and when the exhaust open at lower RPM I loose torque and it sounds rice-ish. So the algorithm would be "if TPS > 80% and RPM > 4000 = output. I've tried using the Air Pump Circuit but the parameter in the expanded 6e XDF are all "or" based for example 4000 RPM or LV8 > 90. The EGR circuit table are duty cycle and only go up to 2000 RPM so I cant use them...anyone know how I can accomplish this with the ECM?
