If you purchased a Procom CDI/ECU with the nine settings or that is fully reprogrammable, you can choose a setting based on your riding experience as well as aftermarket modifications. Please refer to the instruction sticker located on the back of our CDI/ECU.
* Think of a minor modified machine as one that has aftermarket parts that can easily be removed such as a slip on exhaust silencer, spark arrestor, etc.
* Think of a generally modified machine as one that has aftermarket modifications that are not very easy to remove such as full exhaust, air box, etc.
* Think of an aggressively modified machine as one that has aftermarket modifications that are permanent parts of your machine such as engine modification kits, dual exhaust, aftermarket clutch, etc.
