    Stock 2016 ECU flash

    After a lengthy, informative phone call with Steve I decided to ship off my ECU from my stock 2016 to Shoodaben Engineering mainly to smooth the annoying on/off nature of the throttle. The Postal gods smiled on me with two day shipping to Florida.  Steve received my ECU on a Thursday and to my delight I received an email saying it would be shipped back to me Friday, the next day! I received my flashed ECU Monday morning. Round trip from New Hampshire was 7 days. I reinstalled the ECU, reset the idle speed and headed off on a 500 mile trip through the Adirondacks to help care for my ailing mother.
    My first impression was how smooth the engine ran. The 5K rpm vibration was greatly reduced and the throttle roll off progressive. I must admit that I still felt the throttle roll on was still kind of on/off. I did some parking lot practice and while the throttle was much improved it wasn’t totally refined. Two weeks later, mother on the way to recovery, I rode the 500 miles back home.
    During that ride I remembered Steve’s instructions included with the ECU included adjusting the throttle cable slack. I finally got around to doing that two days ago. Yesterday I rode up to Portland, Maine and back; about 130 miles. All I can say is WOW! Taking the slack out of the throttle cable gave me the refinement Steve promised. Now from start up, through back roads, interstates, twisties and parking lots power delivery is silky smooth and predictable throughout the power band.
    Next up is installing tall velocity stacks per Steve’s suggestion. I forget the particulars from his tireless explanation, but I trust that the improvement will be positive and noticeable. I feel very fortunate that I stumbled upon such an amazing bike that is supported by talent like Steve’s. Thank you!

     Glad you like it Deepsea!

      Adjusting throttle cables is a maintenance item that is commonly overlooked. The reason it helps so much with EFI is that when there's slack in the cables there's a long twist before anything happens. The rider doesn't get good feedback and doesn't know how much throttle to apply, and inevitably applies to much. You can't be subtle or controlled. I hope more folks will start adding throttle slack adjustment as a regular maintenance item, all bikes will benefit from keeping the cables properly adjusted with little slack.

    I was out riding this weekend and remembered this comment. I noticed a bit of slack in my throttle cables, so I stopped to tighten everything up.  Throttle control was much improved. 

    Thanks for the reminder!

    Interesting !

    Do propose to remove any slack at all ?

      I think you're asking about removing all the slack? Better be careful with that. It can be done, but if you overtighten to the point turning the bars raises the rpms, you're not going to like it when you're riding and the engine speeds up on it's own.
