Honda CRF110F ECU Flash / Re-Map / Tuning Service 2019+

Our CJR Performance Custom CRF110 ECU Flash is configured to match the modifications installed on your build. Since 2019, we have spent countless hours on the dyno and track testing various setups to make each of these individual custom tunes. Here at CJR, we have built maps for almost EVERY combination of intake, throttle body size, manifold design, camshaft, injector, cylinder head, piston, and exhaust found on the market today. This makes us a great choice when choosing your next modification with peace of mind that we'll have your new tune covered for your future upgrades. 

The CJR Performance ECU Flash has been created on our top of the line Dynojet 250i. Since the beginning of 2019 we have had well over 5,000 dyno runs on the CRF110’s alone which has now created over 500 different tunes to choose from!

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 AND Ignition adjustments for each modification and differ per each intake or exhaust system 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 street motorcycles do. So if you are to make a change to your modification, you will need to get an ECU flash or fuel controller.
