Yes, it can be, but it reduces engine torque so much it it's not worth it.great data, thanks for posting that up. Out of curiosity, can the nozzle position/cmd be set less than 10% ? I assume emp is getting pretty high at that point so maybe it's not worth setting any lower. Also does pw% and nozzle % trend linearly?
It's definitely not a linear relationship due to the angles of rotation and arm lengths. But it doesn't matter since you're going to let the controller find whatever position matches your boost target. I should note that the stock GTD2060VZ actuator is a "dumb" actuator so it requires an H-bridge to run it. I didn't want to fuss with that so I swapped another Hella actuator that already has it's own internal H-bridge and feedback control. It just requires 140hz PWM to work. The arm wasn't clocked right so I carefully drilled out the E-beam weld and tacked it with a MIG. Hasn't fallen off yet!
