I own a 2021 Duke and probably read more than my fair share of ECU information and reviews. I'm pretty much settled on the PowerTRONIC, based on functionality, performance, support, and cost. I've also looked into their newer FuelX devices and questioned why someone would install both. I connected with a few folks from PowerTRONIC and this is the most detailed explanation I've received. I hope this helps the forum, and I'm curious as to thoughts from others regarding why the ECU isn't "enough" on its own.
"FuelX is a fuel optimizer that is focused on refining and enhancing the motor to ensure it runs smooth and is happy. It autotunes the engine to its best optimal parameters constantly monitoring, learning, and adapting to the conditions of the engine like wear and tear, riding style, mods like exhaust/air filter as well as external weather conditions and altitude. It can control the AFR completely, as well as reduce stalling, jerking, and bogging in the initial throttle range and provide a better throttle response.
As a result, the engine will be running in an optimal condition, much cooler operating engine temperature and lesser gear shifts incidentally resulting in performance gains at the lower RPM and throttle percentage region. This initial response helps the engine to eventually pushes more at higher revs and throttle percentages and provides overall performance.
Whereas the PowerTRONIC is a piggyback ECU, its major role is to improve the overall performance of the motorcycle by controlling fueling and ignition. For the open-loop control, you can use the PowerTROINIC which is a piggyback Plug-N-Play ECU that comes with 2 pre-tuned maps. (Map 1-Race, Map 2-Race+). It controls both Fuel and Ignition. You can load the current map as the base map and relatively change the Amount of fuel (in%) and Ignition timing (in degrees) of the bike with the help of R-Tune software."
