Technical features
CDI MHR Team II
Control unit with variable spark
advance timing and with 3
trimmers:
• trimmer MAPS: selects the spark
advance timing map
• trimmer OFFSET: shifts the
selected map ± 2°
• trimmer LIM: selects the rev limit
(16 possible settings)
• 8 preset maps:
» 7 variable spark advance maps
for 2 stroke engines
» 1 fixed spark advance map
• System based on a uP STM8
- 8 bit microprocessor with a
processing speed of 20MIPS
(Million Instructions Per Second).
• Reduced processing time,
improved spark advance
precision and stability.
• Hardware architecture
with improved immunity to
interferences.
• Temperature class 105°C cable.
• Compensation for flywheel fitting
error of ± 2° with 0.5° increments
via an external trimmer
• 8 spark advance tables
selectable via an external
trimmer
• Vector spark advance tables
comprised of 24 breakpoints
with linear interpolation.
• Adjustable rev limit via an
external trimmer with 16
settings.
• Soft cut feature insures a gradual
rev limit cut-off .
• 15 settings to adjust the rev limit
between 11,500 RPM and 14,300
RPM with 200 RPM increments
plus a setting to disable the rev
limiter.
