Malossi PVL Inner Rotor Ignition - MHR II (SMALL TAPER)
MHR Team II ignition is a great innovation!!!
Manages multiple maps simultaneously without having to resort to a hand-held device, with just a simple click. Ability to shift the selected map by moving the OFFSET (± 2°).
The inner rotor ignition systems designed by Malossi are based on the state-of-the-art technology applied to racing. Such a new system resulted from the need to overcome the technical limitations imposed by conventional flywheel ignition, which cannot ensure consistent performance over 10,000 rpm and causes severe setting-up problems for racing vehicles.
We made the control unit even more immune to interferences developing an uP STM8 - 8 bit microprocessor with processing speed of 20MIPS, guaranteeing spark timing with greater accuracy than prior versions!
TheMHR Team IIincludes anot adjustable with 3 trimmerscontrol unit with variable spark advance timing:
the first trimmer (MAPS) is for selecting the spark advance timing map
the second trimmer (OFFSET) allows you to shift the selected map ± 2°
the third trimmer (LIM) used especially for 4-stroke engines, permits you to vary the rev limit between 11.500 RPM to 14.300 RPM and also allows you to disable the rev limiter
It also features8 preset mapsdescribed as follows:
1 variable spark advance maps for 4 stroke engines
6 variable spark advance maps for 2 stroke engines
1 fixed spark advance map
Other essential components have also been revised, such as the high voltage coil, now able to deliver a maximum discharge voltage >40 KV for normal engine speeds from >3000 RPM and an extraordinary ramp up time @10bar> 1750 V/uS. One of the most important novelties is the new rotor/stator unit, featuring a completely redesigned static component in terms of mechanics and electronics!
The installation instructions graphically illustrate the best spark advance setup for different engines.
Electrical performance improved by 20%. Minimum start-up speed reduced from 450 rpm to 370 rpm. The effects of this latest evolution translate into increased voltage supplied to the spark plug, at the same speed, which is anything but negligible compared to the previous model.
