Most bikes either have no sensors or just narrow-band sensors. If you’ve got no sensors, the computer doesn’t know how much fuel the bike needs or not. It feeds in the fuel or withdraws from it based on the pre-programmed system.

Dynojet, on the other hand, provides you with wideband sensors that can tell the system exactly how much fuel it needs to give or take away from the engine.

That aside, when you modify the bike, the stock ECM will have trouble figuring out the bike’s need. That’s where the Power Commander comes to play, as the auto-tuning kit will help it to figure out the system with the data.
