WR450 Computer Adjustable CDI

2 posts in this topic

I was surfing yamaha -racing.com, checking out the factory 2003 YZ450FM race bike specs, and it mentioned that the bike had a YRRD Computer Adjustable CDI. Basically, hook-up your laptop and program your own ignition map to suit your riding style. This, for me, would be the next evolution to the grey wire mod. Has anyone out there in TT world heard of such a unit available to the public ?

Sound interesting. I have a power commander for My R1 that allows Fuel injection mapping and CDI timing adjustments throughout the rev range. That would be cool to have that control on the WR450. I do not know if I would feel comfortable advancing the timing on a dirtbike.
