I'm developing a cylinder deactivation system for the 4.4 V8 Wendover based on a custom engine lua file. While trying to figure out how to simulate cutting off half the engine, I stumbled across the "scaleOutputTorque" function. Added a call to that function in my lua, and it partially works. During low-load cruising, half of the engine will shut off. However, stepping hard on the accelerator doesn't reactivate all 8 cylinders as it should. The Wendover is extremely sluggish accelerating, as it is essentially a 2.2-liter inline-4. In addition, cylinder deactivation doesn't cause the horrible exhaust boom that I expected to hear (I coded a muffling reduction in as well) Uploaded the file, can someone take a look?
