Description

Force Master is renewed!

Besides its improved fuel curves, efforts from Malossi’s technical staff resulted with a rev limiter increase of 1,000/1,500 RPM depending on the vehicle, making Force Master 2 an even higher performing ECU!

Force Master 2 allows to change the injection in order to fit perfectly the new Malossi 4-stroke cylinder kit.

This CDI has been scheduled with 4 different maps so as to be coupled perfectly with your vehicle whatever its setting is!
