2 Stroke Ignition - Configuring Zeeltronic programmable ignition

Warning: This is not a 12,000 rpm video! What I'm looking at here is the theory and thinking behind ignition mapping for the TZR 250 using the Zeeltronic programmable CDI. Full Playlist https://www.youtube.com/playlist?list=PLZS-FDeuf2R3ENz2aWMUTko9niMdZlXA4 At 2:00 I mention you do not get the connectors if buying direct - this is wrong! Zeeltronic do supply with the connectors fitted now - Thanks for the correction Borut! Two stroke tuning is an ancient and mysterious art, but using spreadsheets I can visualise some of this and understand how Yamaha have gone about restricting the TZR for the home market - and most importantly, learn how to derestrict it! I have bought this myself and am not sponsored for my views!
