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. 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!Ģ017-2020 HONDA GROM AVAILABLE TUNES - CLICK HERE!Ģ014-2015 HONDA GROM AVAILABLE TUNES - CLICK HERE!Ģ019-2021 HONDA MONKEY AVAILABLE TUNES - CLICK HERE!ĬJR Performance has been working around the clock on the street as well as the dyno to bring you the most refined ECU tunes. We tend to do all the development on our own bikes, this means we can spend as much time as needed to get the data we require and also test different modifications on the bike to understand how they will effect engine function. As we’re all petrol heads at BHP UK it also means we have nice fleet of bikes to ride and test at weekends.Unlock the full potential of your Honda Monkey/Grom/Super Cub* 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. We will run and monitor the bike in all the engine modes available thus building a complete picture of the bike’s standard mapping. On many occasions we find that the manufacturer has restricted throttle opening or imposed torque limiters in the mapping in an attempt to sedate power delivery or meet emissions standards. The data we collect gives us an idea of how the manufacturer has set the bike up and where improvements are possible. Some of these parameters we can log through the bike’s OBD while others will require external analogue output sensors. We also need to take other measurements including, throttle position, spark advance, throttle plate position, knock detection, engine oil temperature, engine coolant temp, exhaust gas temperature and injector duty cycle. We use our Dynojet 250i to run the bike and measure power output. We will attach our own lambda sensors to monitor Air Fuel Ratio (AFR). When we develop a remapping strategy for any motorcycle we will run the bike on our dyno and monitor every possible aspect of engine function. Remapping will save the expense of buying a tuning module or “piggy back ECU”.Whenever a bike is modified with aftermarket upgrades such as an exhaust system or air intake is essential to remap the ECU to ensure the engine is running correctly.Īll our remaps are developed in house by us at our fully equipped facility in the UK. We do not use base maps from other companies and simply tweak them to run on your bike. Many bikes will have the power restricted in certain gears and certain engine RPMs to meet increasingly restrictive emissions regulations.ĮCU remapping is the science of altering the parameters in the ECU to make the engine run optimally. The ECU will also have torque and power limiters to limit the power produced in certain situations. The Motorbike ECU (Engine Control Unit) is now a very sophisticated computer and controls every aspect of engine function including fuelling, spark advance, throttle plate opening and closed loop lambda monitoring. All of our remaps are developed by our in house team of map writers. Expert Motorcycle Remapping & Bike TuningīHP UK has over 20 years of experience in the ECU remapping industry (also known as chipping, flash tuning and ECU tuning).
