At 750 RPM to 1500 -064 adds 2 points at 0% throttle which slightly enriches the startup. The following is -064 compared to -002, Top row is Throttle % open and left column is RPM Hope it comes thru...

-064 is leaner in some areas so you want to listen for pre-ignition ping. I have used the Accelerator Pump Utility to eliminate ping. From Power Commander Site:
The Power Commander V has a feature called Accel Pump. This gives you the ability to add, or remove fuel for a short time when the throttle is moved quickly. The three options need to be configured to accomplish what you want to achieve.
Trigger is the amount of throttle movement. A value of 20 means if the throttle is quickly moved 20 percent or more, the Accel Pump is activated.
Duration is the length of time the Accel Pump would be active. For example a value of 83 would give about one second of fuel at 5000 rpm, and two seconds of fuel at 2500 rpm.
Fuel Adjustment is the percent of fuel to add, or remove. Positive numbers add fuel, negative numbers remove fuel Power Commander Accessory Issues

No, you can't change the way it works - that is a function of the factory ECM needing to see the Crank signal. When you key up, the system is awake and ready to go. When it doesn't see the crank signal, things shut down in the EFI system. Then when you crank, the PC interrupts the crank signal that is needed to fire up the factory EFI. If the PC was not there, the factory ECM would see the signal immediately. Just hit the starter before the light goes back out and you should be ok.
