We have successfully developed and tested Stage 1+ tuning for the new Loncin XWolf 1000 ATVs, which feature an electronic throttle and the Bosch ME17.8.10 ECU. Our tune features a completely reworked torque model, air-fuel mixture settings, ignition timing, electronic throttle control algorithms, and more. This results in a significant increase in power and torque, linear throttle response across all operating modes, the elimination of abrupt jerking, and stabilized engine performance at medium to high RPMs. Additionally, the maximum RPM limit has been raised, speed restrictions in L, H, and R modes have been removed, and the Overdrive button function has been disabled.
