Pin Assignment
The pin assignment of our CDIs is as follows:
 | 1 = +12 volt on-board power supply (via fuses, ignition switch, and kill switch) 2 = Side stand monitoring 3 = Ignition coil 1 4 = Ignition coil 2 (pin is not used with cdi650) 5 = Pulse generator 6 = Battery minus (chassis) |
If there is a jumper on CDI, it connects pins 2 and 6.
Wire jumpers
 | Our CDI for XL600V (PD06) und XRV650 (RD03) have a yellow wire jumper. This wire exists because Transalp models without side stand monitoring (year of manufacture 1987) have a slightly different pin assignment. The jumper must remain intact for these models. For other models, the jumper must be cut (e.g. with a side cutter) to activate monitoring. |
 | Our CDI for the NX500 (PD08), NX650 (RD02/RD08), and XR650L (RD06) have a blue wire jumper. This wire exists because models without side stand monitoring exist that have a slightly different pin assignment. The jumper must remain intact for these models. For other models, the jumper must be cut (e.g. with a side cutter) to activate monitoring. |
Two CDI Types
Our CDIs are available as dual-line or programmable versions. The two CDI types are described below.
|
|
|
| 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). |
 |
| Mode 1: To activate the legacy ignition map, the jumper is inserted into the two upper pins of the left 3-pin strip. This ignition map corresponds to the original CDI and is conservatively designed for the octane number of standard gasoline (91 RON). Using this configuration makes sense, for example, if you fill up with low octane gasoline abroad. Mode 2: The advanced ignition map is the recommended setting and is optimized for today's octane rating of Super Petrol (95 RON or 102 RON). To activate it, the jumper is inserted into the lower two pins of the right 3-pole strip. If this mode is activated, the torque, power and efficiency of the motor increase. |
| Please note: Regardless of the activated ignition map, the jumper between the lowest two pins of the upper 5-pin strip (see grey marking in the picture) needs to remain in place. It ensures that the microcontroller functions correctly in the event of electromagnetic interference and must not be removed. |
| 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. The CDI 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. By the way, our CDIs can be reprogrammed during operation (e.g. useful for measurements on the test bench or with a stroboscope). Links and further information can be found here. | |
