Tuning performance CDI for SYM Pure 50 year 1997-1998
With this further improved, open CDI unit (without speed limitation and with optimized ignition curve you can exploit the full potential of your cylinder kits and exhaust systems.
The speed limit for original ignition units is approx. 8,000 - 9,000 rpm.
In this area, many exhaust systems or cylinder kits are just starting to unleash their power. In addition, the optimally adjusted ignition curve brings a further increase in performance.
Can also be used on untuned engines to dethrottle the vehicle.
But this only makes sense if the dethrottled engine manages to turn in the speed limit of the original CDI.
A must for tuned engines.
