So you just bought a Kheper v3 unit and you want to know how to use it? This little tutorial is made you. Kheper V3 is a CDI device that controls the exact timing when to trigger the spark according to a user defined profile (called here curves). Prerequist: 1-Check that you scooter is compatible here Is it compatible with my scooter? You have 2 different ways to load to define the curve you want : LEVEL 1: The plug and play experience:
- Just use the selection wheel (next to the USB, turn it with the little included screwdriver) to select your scooter model as following : 4-PX125, 5-PX200, 6-PK-ET3, 7-V.TRONiC, 8-Lambretta, 9-MOD, A to E-Race.
- Please check that you stator is at the position and get more detail about presets herer :
1-Go to http://editor.kheper-scooter.com and edit curve 1, 2, 3 to your needs. This only works with IE, Firefow and Chrome, NO support for Safari.
2-Once your done with the editing click on “Download” at the bottom of the page, it will download a file named “kheper3.csv”. Drag and drop the file on the kheper drive (the selection wheel have to be in ‘F’ position)
3-Unplug and plug the USB for at least 5 seconds, if it worked you should have now a file “sucess.txt” on the drive You now have curve 1, 2, 3 loaded with your presets (presets for 4 to E are still available), to use it just select the selection wheel to 1, 2 or 3.

This is the ANdroid and IOS application to install:
Now that your Kheper V3 is programmed you can install it on your scooter: Left to right you have to connect the colors to Kheper in the following order: White (ground) – Red (pickup) – Green 1 (Alternator) – Green 2 (Alternator) You can connect the green wire to Green 1 or Green 2 this is the same as they are internally connected together.:
Remember that as your motor will reach higher RPM, you would like to increase your carburetor jets by a few points. I also recommend that you check your exact stator initial position using a stroboscopic lamp.
