Malossi Team II Inner Rotor Ignition for Aprilia / Piaggio / Vespa

If you have removed or held a factory flywheel in your hands before, you’d know how heavy they are. Each time the throttle is applied, the crankshaft has to forcibly spin up the weight of this giant engine anchor which is hanging directly off its side. Inner rotor ignitions essentially work in the reverse, having a super light flywheel built into a the inside of the stator rather than rotating around the outside – keeping the heavy part of the system un-driven, and the driven part of the system as close to the centre of the crank as possible to reduce the effect of centrifugal force. This allows the engine to far more rapidly rev, as the flywheel is providing far less resistance to the engine changing rapidly in RPM.

TECHNICAL FEATURES

CDI

Control unit with variable ignition timing and 3 trimmers:

MAPS trimmer: selects the ignition timing map
OFFSET trimmer: shifts the selected map by ± 2°
LIM trimmer: selects the rev limit (16 possible settings)
8 preset maps:

1 variable ignition timing map for 4-stroke engines
6 variable ignition advance maps for 2-stroke engines
1 fixed ignition timing map
The system is based on a uP STM8 – 8-bit microprocessor with a processing speed of 20MIPS (Million Instructions Per Second).
Reduced processing time, improved precision and stability of ignition timing.
Hardware architecture with improved immunity to interference.
105°C temperature class cable.
Compensation of the flywheel installation error of ± 2° with 0.5° steps via an external trimmer.
8 ignition advance tables, selectable via an external trimmer
Vector ignition advance tables with 24 interpolation points and linear interpolation.
Adjustable speed limitation via an external trimmer with 16 settings.
The soft-cut function ensures that the speed limit is gradually switched off.
15 settings for adjusting the speed limit between 11,500 rpm and 14,300 rpm in steps of 200 rpm as well as a setting for deactivating the speed limiter.
