The "PA ENABLE" wire must stay powered with 12 volts to use this feature.
This is the same wire used to trigger the internal logger,so triggering the logger with your tbrake will not work as you will drop the signal when released.
add a switch to flip after your burnout.
With the said.
go online hit "F6" make sure the "PA Mode Enable" box is checked off
Make sure the "PA Fuel Tables" box is NOT checked off.
and set the activate and deactivate RPMs.
this may seem backwards but its not.
The Deactivate RPMs is a LOW shutoff point(in case you your RPMs drop below),so be sure its lower than the activate or it will not work.
Hope this helps
