Our solution for IDM CDIs for touring engines
All IDM-based ignitions (Vespatronic, Malossi VesPower, Polini IDM, Varitronic, Pinasco Flytech, Parmakit etc.) use the same CDI. The ignition curve of this CDI 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 the partial load range 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, performance suffers in the upper engine speed range, as the CDI already reduces the ignition timing considerably at this point. We have addressed this problem and developed a solution:
Advantages of our bgm PRO CDI for IDM with touring setup
The bgm PRO CDI has a modified, optimized ignition curve. It offers ideal working conditions for high-torque touring engines that have a similar power/torque curve to an original engine. The adjustment of the ignition timing is significantly less, 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.
The technology of the bgm PRO CDI is housed in the vehicle-specific ignition coil housings of the period. Despite the modern technology, the beautiful old look for classic Vespa and Lambretta is retained. In contrast to an original IDM CDI, the ignition cable can also be screwed in. Ideal if the CDI needs to be positioned differently or the ignition cable simply needs to be replaced.
CONCLUSION:
Perfect addition for high-torque tuning engines that need to be even better.
