ECU Chiptuning Power Tronic V4 Yamaha YZF-R125 from year 19 (RE39/RE40)

The"PowerTRONIC V4" is one of the most advanced "piggyback control units" with full range of functions for motorcycles currently available worldwide. "Piggyback" in this case means that this control module is used in addition to the original control unit. 

The PowerTRONIC ECU connects in minutes and delivers improved performance, through user-adjustable fuel and ignition assignments. Tuning professionals also have the option of programming  the ECU themselves via the appropriate app (Windows or Android). Those who prefer not to program themselves can also download pre-made maps.

Features

Plug & Play

Easy installation in about one hour. No special tools need to be used.

Improved throttle response

Particularly in the part-load range or at low engine speeds, the engine's throttle response is significantly optimized, allowing for sportier and thus more pleasant driving in this speed range.

Power & torque increase

New injection and ignition curve programming maximizes engine power and torque in every load range. Two mappings are pre-installed, these can be changed by a connector on the wiring harness.

High-quality components

Of course all components are of the highest quality and of course water & heat resistant.

Expandable with Race Dynamics Quickshift Sensor & Handlebar Switch

The sensor detects movements of the shift pedal and automatically throttles the injection to allow clutchless shifting (only recommended for experienced drivers!). Two different maps are pre-installed on the ECU. By an additionally available handlebar switch, the map can be changed without having to work on the wiring harness.
