Inner Rotor Ignition MALOSSI

MHR TEAM, for MINARELLI LC
adjustable

FOR RACE USE ONLY

MHR Team 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 dramatically modified the control unit to create two new Inner Rotor Ignitions: MHR and MHR Team.

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!

The MHR version includes a control unit with variable spark advance timing, not adjustable.

The MHR Team includes a control unit with variable spark advance timing and with 3 trimmers:

  • 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 features 8 preset maps described as follows:

  • 2 variable spark advance maps for 4 stroke engines
  • 5 variable spark advance maps for 2 stroke engines
  • 1 fixed spark advance map

The installation instructions graphically illustrate the best spark advance setup for different engines.
