Installation

!!! WARNING !!! Before working on your machine, make sure it is parked on a level surface with the transmission in park and/or the parking brake engaged.
Do not work on any machine with a hot engine or exhaust.  Allow time for all parts to cool in order to reduce the risk of burns.

The Power Commander Fuel Controller (PCFC) will come pre-loaded with multiple maps including a custom map for an HMF exhaust specific to the machine.  

The "BASE" dial controls which map is active and will be preset from HMF to the specific map for the HMF exhaust (typically the next map position after the listed maps in the DynoJet instructions).

Follow all other directions from DynoJet for the specific installation of the PCFC.(See Figure #1)
