Service
ATV SWAP
Professional ECU calibration after engine replacement or modification.
We will match the electronics to the new unit to ensure it operates with full power and reliability.
About the Service
At MotoStrefa MS-PERFORMANCE, we specialize in tuning and calibrating ATV vehicles after engine swaps.
Engine replacement or modification of intake and exhaust systems requires precise adjustment of fuel, ignition, and throttle maps to ensure an optimal mixture and safe operating conditions.
Thanks to our experience working with various ECU platforms (Keihin, Bosch, Denso, Siemens, Mitsubishi, Magneti Marelli, and others), we are able to tune any project — from lightweight quads to extreme track builds.
Every modification is verified on the road and off-road, guaranteeing real and repeatable results.

Effects and BENEFITS
Why MS-PERFORMANCE
Because we understand that a swap is not just mechanics, but also electronics.
We don’t limit ourselves to ready-made maps – we analyze each configuration individually.
Our facilities (load dynamometer, WinOLS 5, AFR loggers, wideband sensors) allow us to achieve perfect tuning even in the most unusual projects.
