    How do I adjust PE in Tunerpro RT?

    I've been searching but can't find any tutorials on how to adjust PE in Tunerpro RT. Truck runs good at steady speeds but when you hit the gas it jumps like it wants to get up and go then falls on its face a little and the WBo2 shows lean.

    Adjusting the PE parameters to a lower AFR will add fuel to PE. For example if the current PE AFR is 13.5 AFR, lowering to AFR 13.0 will add fuel. Adjust PE AFR's to a higher number to lean the PE fuel.

    Except for acceleration enrichment, the fuel parameters are based on correct numbers in the VE tables. PE values tell the computer what AFR to deliver, and the delivered AFR should be close to the WB displayed AFR. If the engine tries to get up and go then falls on it's face when snapping the throttle, and the WB is showing much leaner than commanded AFR, it suggests the VE cells for high MAP need adjustment.

    Hey Jimmie, I've been following your threads because we are experiencing the same problems. I think my knock sensor is the problem. I unscrewed it and installed it hand tight (just enough to stop coolant from leaking) and it made a big difference
