CDI derestricted Rieju MRT / Vent RR / Sherco SM Euro 4 / 5 after 2018 (24 pins)
incl. tax, plus shipping
Description
open CDI AM6 Euro 4 and Euro 5
Derestricted CDI unit without rev limiter. The CDI has an optimized power curve and the elimination of the rev limiter means that you can reach significantly higher top speeds. Can be used plug and play, but is also suitable in combination with other tuning parts.
Why use an open CDI?
The CDI unit on original 50cc two-wheelers is usually restricted by the manufacturer in order to meet the applicable emissions standards, in this case the Euro 4 / Euro 5 standard. This limits the vehicle in terms of power and top speed.
To increase performance and top speed, you can install an open CDI to remove this restriction.
Please note: It will also be necessary to replace the CDI if you install a sports/racing cylinder or performance exhaust.
Installation of CDI module AM6 E4 / E5:
Installation of the open CDI is extremely simple, as it is a plug & play system. Unplug the old CDI, plug in the new one and the installation is complete!
- Plug with 24 pins
Suitable for Rieju MRT / Drac / Tango / RS3 Euro 4 / Euro 5 from 2018, Sherco Euro 4 / Euro 5 from 2018, Fantic Casa Euro 4 / Euro 5 from 2018, Vent Baja / RR / Derapage Euro 4 / Euro 5 from 2018
Attention: To be on the safe side, please compare the plug of the vehicle with the picture before ordering !!!
CDI and coil
The CDI (for Capacitor Discharger Ignition) and the ignition coil are an essential part of the ignition. While the coil is actually just an energy storage device that supplies the ignition spark to the spark plug, the CDI module is a more complex component that controls the engine speed at which the spark should occur. It can therefore have an effect on engine behavior and performance.
Open CDI
Many riders equip their 50cc geared mopeds and scooters with open, i.e. derestricted CDIs. In most cases, the original CDI throttles the maximum achievable engine speed, which significantly reduces performance and top speed.
To remove this rev limiter and thus increase maximum speed, you can install a CDI without a rev limiter instead of the original CDI.
Beware! When using an open CDI, the carburetor must be readjusted, so it is best to order new jets as well.
Programmable CDI
Programmable CDI control units are available for tuned racing engines on 50cc scooters and moorcycles as well as for motocross bikes. These CDIs are designed for more experienced tuners who want to optimize the settings of their two-wheeler as much as possible.
With a programmable CDI, the ignition timing is dynamic so that the spark always jumps at the optimum time at both high and low engine speeds. This leads to a better increase in speed, higher torque and an overall increase in maximum power.
4-stroke engines with fuel injection are equipped with an ECU (Electronic Control Unit), which also controls the fuel injection. When tuning a four-stroke engine with an electronic injection system, a programmable CDI is therefore an absolute must in order to avoid breakdowns and engine damage.
Symptoms of a defective coil or CDI
If these two elements fail, the symptoms are usually very easy to recognize: no spark at the spark plug, so the engine will not start.
It is best to proceed in sequence: First change the spark plug, then the spark plug cap, then the coil and only then consider the CDI or the ignition itself as the source.
