Having got my MOT (passed 
) at the weekend I've had a chance to see what the EJK box has done to the actual performance of the bike now and give an update.
Â
Overall, I'm really pleased and feel it was worth it (for me).
Â
My particular bike seemed the most jerky I've had (this is my third niner) - not sure why or if they changed fueling etc (it's a 2007 model) but the on/off throttle is pretty bad.
Â
So, while it's still got a little of the on/off character, which is impossible to remove without a remap as it's due to the injectors cutting out on deceleration, the overall fueling is definitely improved and it's more like the previous TDMs I've had, much smoother and pulls great across the rev range.
Â
I wouldn't say it's added much power, certainly not enough to make the "bum dyno" notice, but the fueling is much nicer, and I know it's not running lean anymore. I think the jerkiness probably was from being too lean in that case, so I'd probably say if your bike is running fine and you've no concerns, just enjoy it, but if you're having issues or worried it's lean after changing silencers etc, then this is a nice easy option over the more expensive power commander.
