So it is important we set you up on the tune that fits your build the best. A Hindle exhaust vs a Yoshimura exhaust for example have drastically different fuel tables.
#BOSS RACING ECU FLASH MODS#
Disable EVAP Canister Check Engine Light (For removal of the emissions canister)ĭuring checkout, specify your mods so the proper flash can be applied to your sale. Optional Side Stand Delete (Often used for racers when deleting kick stand Optional Decel Fuel-Cut (Less engine braking, smoother on/off throttle) Great for stunt riders that would like to be able to raise their idle without having the it creep up while riding!) Optional Learning System Disable (A fixed open loop map, for intake/exhaust bikes only. 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 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) 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. OEM ECU 2014-2015 OG Grom AND 2017 SF Grom = 0-64% Closed Loop Flashed ECU Target 60-100% TPS = 12.8-13.2 AFR for optimal performance
Flashed ECU Target 0-60% TPS = 14.7 AFR for optimal fuel economy This flash retains the stock learning trims for idle/partial throttle, with open loop (no autotune) wide open throttle Custom RPM Limit with "Race Limiter" (Faster/Smoother RPM Limit) These tunes would fall in line with the average ECU flash needed for day to day use. It includes a custom tune specific to your build. This is our basic tune option for budget friendly performance. The other option is to purchase a brand new OEM Honda ECU in which we flash that comes with a 1yr warranty and receive a return credit for the used stock ECU you send back to us for $50 (customers within the USA). You have the option you mail in your current ECU for us to flash to your modifications. 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! THIS ECU FLASHING SERVICE IS COMPLETELY CUSTOMIZABLE. A CJR tuned monkey with an aftermarket intake and exhaust nets 10hp at 8,000rpm and 9hp at 9,000rpm. What does this ECU flash improve? Let’s look at the graph and talk numbers - A Monkey for example, with a stock intake & exhaust makes 8hp peak at 6800rpm and 6.5hp at 9,000rpm.
We are partnered with our family Honda dealership right next door which allows us quick access and affordable prices. 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. CJR Performance has been working around the clock on the street as well as the dyno to bring you the most refined ECU tunes.
