![]() ![]() 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. 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. Bespoke ECU Tuning and Programming for Triumph Motorcycles - Global Digital Delivery, Domestic USA and International Mail-In Options Available. ![]() The data we collect gives us an idea of how the manufacturer has set the bike up and where improvements are possible. Have a concept for a motorcycle that you’re itching to make happen, speak to us about making that a reality. 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. Discover Exclusive and World First protocols available for bFlash users: Mercedes 8G-DCT Gearbox. 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. It would on my Aprilia for sure because I have no O2 feedback on that bike, but Chris and Emmanuel's Triumphs would likely realize no benefit down low, and as I recall in another thread, that is the performance area Chris would like to improve.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). In terms of relevance to this thread, Tune ECU maps might have no effect at those lower revs. ECU Flashing, Tune Fuel Maps, Ignition Maps and other Advanced Settings in your Motorcycle ECU. The red line is what’s called Stage 1, with just an ECU flash on an otherwise stock bike. In fact, I would not be surprised to see mid-to-low 14s throughout the majority of the rev range if half-throttle or less was maintained. The blue line is the baseline run with the completely stock bike. If you’re looking to become a Viezu Approved Dealer or you are a current Master File writer. Our ECU tune software is all written in-house by our highly skilled and highly experienced remap support team. I am not surprised to see mid-14s on modern motorcycle engines down low. Viezu offers the very best in- car tuning software and support, including ECU tuning & Remapping files. With zirconia oxygen sensors generally only accurate from about 13.8:1 upwards of 15.1:1, it is imperative these systems maintain stoichiometric efficiency during closed-loop controls. In addition to taking input from the rider’s wrist, the ECU also receives signals indicating lean angle and acceleration from the Inertial Measurement Unit, traction control system input, and in some cases ABS signals to name a few. That is typically where EPA measures for emissions compliance, and most systems maintain feedback controls until above 4K at WOT. The Engine Control Unit is only one of several control units on a modern motorcycle. However, I would suspect if these graphs are accurate at all, the lower end is pretty close. Maybe so, sort of like every torque graph intersects HP line at 5250 RPM due to the formula. With the press of a button, it will flash your motorcycle’s ECU. ![]()
