I bought the Programable CDI from http://ignitech.cz/en/ . I really efficient company, well informed sales team and fast delivery by DHL. It plugs directly into the original wiring loom, they supplied me a copy of their programme on a CD, even though it could be downloaded from their website. The whole process was incredible undramatic.

The biggest stumbling block was to find out the original advance curve as a base line setting, I searched high and low but no joy so in the end I used what I thought would be right, wired up the CDI and fired up the XTZ. I spent a while adjusting the parameters in my workshop before venturing out. To fine tune I used a local hill and a pieces of flat road, basically I went up and down the hill adjusting after each run and used the flat road for acceleration and top speed testing. I used my Gps to verify the results. I adjusted more for torque than HP. So after a couple of afternoons playing around with CDI and re jetting the carb it runs really sweetly. I did set the rev limiter 1500 RPM above the original setting just to give a bit more power if a really need it but I must admit I have hardly used it.

There are some functions that I have not used so far but I plan to use soon, the most important one is a rev counter output, followed by a shift light.
