BGM PRO CDI for IDM retrofit ignitions
Original look combined with an optimized ignition curve for touring engines.
THE PROBLEM OF THE ORIGINAL IDM CDI ON TOURING ENGINES
All IDM-based ignitions (Vespatronic, Malossi VesPower, Polini IDM, Varitronic, Pinasco Flytech, Parmakit etc.) use the same CDI. Their ignition curve is designed for high-performance engines with late power input and high engine speeds. On touring engines with early and high torque, this ignition curve is rather counterproductive. It often leads to engine judder in part-load operation due to the ignition timing being too early for the low engine speed. However, due to the large adjustment range (8°) of the original CDI, the ignition timing must be selected early. Otherwise, the performance in the upper speed range suffers, as the CDI already reduces the ignition timing considerably at this point.
ADVANTAGES OF THE BGM PRO CDI ON TOURING ENGINES
The BGM PRO CDI has a fixed ignition timing. It offers ideal working conditions for engines with a similar power/torque curve to an original engine. There is no need to adjust the ignition timing, the engine runs more quietly and smoothly and also develops more power, especially in the range above peak power (overrev). The result is an engine that is much more touring-friendly and is usually even a little faster.
FURTHER ADVANTAGES OF THE BGM PRO CDI
Compared to an original IDM CDI, the ignition cable can also be screwed in. Ideal if the CDI is to be positioned differently or the ignition cable simply needs to be replaced.
