| Digital Double-CDI for |
| Made in Germany |
Our CDIs are produced in Germany and have evolved into a true success story over the years.
| Digital Design |
Our ignition boxes are DC-CDIs and a complete redevelopment of the original CDIs, where many analogue and meanwhile ancient parts were replaced by modern and more robust components.
Advantages of our digital design
Modern ComponentsOur digital ignition boxes are DC-CDIs with modern components that have not been available yet when the original CDIs were designed. A sophisticated protection circuit using a special IC protects our CDIs against overvoltages. Thyristors connecting the ignition capacitor with the ignition coil to trigger the ignition were replaced with a modern IGBT. The bipolar transistor of the voltage converter was replaced with an FET with significantly lower switching losses.
Optimized for Super PetrolThe ignition map of the original CDIs is conservatively designed for normal gasoline (91 RON) or worse. Our CDIs allow you to choose between the original map and another one optimized for super petrol (95 RON). With this configuration, torque, power and efficiency of the engine increase noticeably.
Constant Charging VoltageThe charging voltage of the ignition capacitor remains constant even when the engine reaches maximum speed. In the original CDIs,s a significant voltage drop can occur since the time frame for recharging the capacitor between ignitions decreases.
Efficient Voltage ConverterOur built-in voltage converter is highly efficient. If the battery voltage falls below a critical threshold (e.g. due to cold temperatures, wear and tear, or long idle times), our CDIs compensate the low voltage with a moderate reduction of the ignition voltage instead of a rigorous increase in the resulting current.
Overvoltage ProtectionOur CDIs feature an integrated protection circuit using a special IC. While the analogue CDIs can be critically damaged by faulty voltage controllers, our CDIs are protected against overvoltages, voltage reversals, and other risks (such as loose connector contacts).
Easy Fault DiagnosisAll our ignition boxes are equipped with an indicator light (LED) which lights up for 1 ms with every ignition. From about 2000 RPM upwards, the human eye perceives this as permanent light. When the LED lights up, it is ensured that the CDI is powered by the on-board power supply (fuses, ignition switches, kill switches, plugs etc. are therefore OK) and that the pulse generators function. An error in the ignition system can then be excluded with a high degree of certainty. One obvious conclusion would then be that the fault is in the gas/air mixture (test with start pilot recommended).
Two versions available
Our CDIs are available in two versions. Please select the version you want to order from the drop-down list above.
|Type: dual-line |
This is the "plug & play" version of our CDI and the recommended version for normal motorcyclists - just install and go. The CDI is compatible in all respects with the original Honda CDI, but comes with an optimized ignition map. If desired, it is possible to switch between the preset advanced ignition map and the standard ignition map of the original CDIs by moving the jumper on the CDI (see picture).
|1) The standard ignition map corresponds to the original and is conservatively designed for the octane number of regular gasoline (91 RON). It makes sense to use this configuration if you are travelling abroad and use gasoline with a low octane rating. |
2) The advanced ignition map is the recommended setting and is optimized for today's octane rating of Super Petrol (95 RON). In the medium speed range, the ignition is triggered earlier, which gives the twins noticeably more power.
|Type: programmable |
For technically experienced users, we also offer the CDI as a programmable version. This version can be configured from the computer or laptop via the USB interface within predefined limits. Our software allows adjusting the ignition map, ignition voltage, pulse generator switching edge, sensor type and its parameters as well as the side stand monitoring. Our programmable CDIs can in principle be used in all motorcycles where either a CDI system already exists or in which such a system can be installed.
|CDI Converter USB cable Laptop/Computer with Windows|
|In order to program the CDI, it is connected to a computer with Windows operating system via a converter and USB cable. To do this, plug the converter into the six pins of the CDI and connect it to a USB port of the computer via the connection cable. We offer converters and cables separately in our shop, since only one set of accessories is needed for programming several CDIs.|
|The CDI is programmed with our software CDI Tuner. The software is freely available for download together with the required drivers and can be accessed without purchasing a CDI. There are predefined profiles for all supported motorcycles, which can be modified as desired. Links and further information can be found here.|
|Please check the legal situation regarding modifications. We do not assume any liability for damage or violations of the law.|
|Just like with the original CDIs, spark plugs with an integrated resistor must be used, recognizable by an R in the designation (e. g. NGK DPR8EA-9).|
|The case dimensions of our CDI are slightly different from the original. |
Dimensions (without plug): 130 x 93 x 21 mm (5.12 x 3.66 x 0.83 inches)
|And last but not least: We are always happy to help you with any questions you may have. Do not hesitate to contact us.|
