Malossi Mhr team II 5519630 internal rotor ignition for horizontal and vertical Minarelli.
It manages multiple maps at the same time without having to resort to PDAs, with a simple click. It allows you to translate the selected map by moving the OFFSET (+ or - 2 °).
Malossi ignitions concentrate in themselves the maximum of technology applied to competitions. The new internal rotor ignitions arise from the need to overcome the technical limitations of the original flywheel-ignition groups, which above 10,000 rpm do not guarantee a constant performance, causing considerable and sometimes insurmountable tuning problems.
We have made the control unit even more immune to disturbances, developing a microprocessor based on uP STM8 - 8 Bit with higher computing capacity @ 20 MIPS to guarantee a much higher spark accuracy than the previous version!
The MHR Team II range is equipped with a non-remappable variable advance control unit with 3 trimmers:
the first (MAPS) to determine the selection of the advance map
the second (OFFSET) allows to move the selected map + or - 2 °
the third (LIM) indicated especially for 4-stroke engines, allows you to vary the intervention of the rev limiter (from 11,500 to 14,300 Rpm + limiter excluded)
It is also equipped with 8 preset mappings which are divided into:
1 for 4T variable advance engines
6 for 2-stroke engines with variable advance
1 with fixed advance
The other key components have also been revised such as the high voltage coil, now capable of delivering a maximum discharge voltage> 40 KV for normal engine speeds from> 3000 RPM and an extraordinary rise time @ 10bar> 1750 V / uS.
One of the most important innovations is the new rotor-stator group, whose static component has been completely redesigned from a mechanical and electronic point of view!
In the assembly instructions all the graphs will be provided in order to best set the advances on the different engines.
Electrical efficiency improved by 20%. Reduction of the minimum starting speed from 450 rpm to 370 rpm.
The effects of this latest evolution translate into an increase in the voltage delivered to the spark plug, with the same rotation speed, of anything but negligible significance compared to the previous model.
