These CRF110’s run very lean when adding just an aftermarket exhaust, which gets worse with an intake. The CJR ECU Flash has revised fuel and ignition timing to target the most powerful, yet most reliable tunes available. It is important to keep in mind, one tune does not fit all. These ECU’s need different fuel adjustments for each modification so it is important to have a tune to match. The CRF110F runs a fixed open loop fuel map utilizing a MAP sensor. This means without an O2 sensor on the head or exhaust, it does not have a learning system to make slight changes for engine modifications like most motorcycles do. So if you are to make a change to your modification, you will need to get an ECU flash or fuel controller.
