Unlock the full potential of your Honda 2019-2021 Honda Monkey with a CJR Performance ECU Flash! With OVER 100 DIFFERENT CJR CUSTOM TUNED ECU flashes to choose from, we will make sure your bike is paired to your exact modifications in addition to custom preferences. The best part, with so many options to choose from, as you upgrade your bike, we’ll likely have a tune ready for your new parts! CJR Performance has been working around the clock from the dyno and to the street to bring you the most refined ECU tunes. We have over 6,000 dyno runs with just groms/monkeys alone! We currently have 4 test bikes that we interchange components with to offer additional flashes and/or diagnose any issues a customer may be having. 

Want to flash the ECU yourself and have our tunes emailed directly? Purchase a Dynojet PV3 and it comes with a FREE CJR Spec tune to match your build!

What does this ECU flash improve? Let’s look at the graph and talk numbers - On our Honda Monkey with a stock intake & exhaust we see it make 8hp peak at 6800rpm and 6.5hp at 9,000rpm. A CJR tuned monkey with an aftermarket intake and exhaust nets 10hp at 8,000rpm and 9hp at 9,000rpm. That is a 2hp peak and 2.5hp at 9,000rpm, although that doesn’t sound like much, that makes for a 20% increase over stock! Want the best big bang for the buck? Add in a high lift camshaft and an average 30% increase will bring 10,000rpm up to a solid 12whp!

CJR PERFORMANCE ECU FLASH -
This is our basic tune option for budget friendly performance. It includes our off-the-shelf custom tune specific to your build. These tunes would fall in line with the average ECU flash needed for day to day use.

- Revised Fuel Map
- Revised Ignition Map
- Custom RPM Limit with "Race Limiter" (Faster/Smoother RPM Limit)
- This flash retains the stock learning trims for idle/partial throttle, with open loop (no autotune) wide open throttle
- Revised Closed Loop areas -
-- Flashed ECU Target 0-60% TPS = 14.7 AFR for optimal fuel economy
-- Flashed ECU Target 60-100% TPS = 12.8-13.2 AFR for optimal performance
(OEM ECU 2019-2021 Monkey = 0-90% Closed Loop at 14.7 AFR)
-- We revise the autotune areas from the factory 0-90% down to 0-60% throttle for all models, this dis-allows the closed loop to have an affect on the open loop portion of the map which causes the bike to lean out after learning miles for wide open throttle.
- Optional Fast Idle Valve Delete - (For those that may not like the loud cold start in a quiet neighborhood, you can also unplug your gray sensor on the throttle body)
- Optional Tip Sensor Delete (A lot of racers will delete the tip sensor to save weight along with some stunt riders relocating their sensor for a subcage)
- Optional Learning System Disable (A fixed open loop map, for intake/exhaust bikes only. Great for stunt riders that would like to be able to raise their idle without having the it creep up while riding!)
- Optional Decel Fuel-Cut (Less engine braking, smoother on/off throttle)
- Optional Side Stand Delete (Often used for racers when deleting kick stand
- Disable EVAP Canister Check Engine Light (For removal of the emissions canister)
- Revised Tip in Fuel Tables
- Revised Tip in Ignition Tables
- Revised Injector Timing
- Revised Oil + Air Temperature Settings
- Includes 1 yr warranty

During checkout, specify your mods so the proper flash can be applied to your sale. A Hindle exhaust vs a Yoshimura exhaust for example have drastically different fuel tables. So it is important we set you up on the tune that fits your build the best.
