ECU change.

Hi all,

Just wondering if a early generation Versys ECU will work in a 2015 model?

I have a restricted version and just wondered if the ECU swap woud be a simple derestrict.

Thanks...

The 2015 has an updated ECU, and I don't think it is compatible with earlier versions. For example, the 2015 has a different TPS voltage range. I believe you would need to have the 2015 ECU flashed/reprogrammed to remove all restrictions.

Thanks for that info... have to admit even restricted it does seem to have ample power for general use.

No need to replace your ECU... You just have to remove a screw on the throttle cam, and remove the restrictor loop connector.

As far as I am aware, the 2015 / 2016 versions are different to the previous models. My 2015 has not got a loop connector and have been told they need ECU reflashing to derestrict by my dealer.

Ah well... Who knows? Do you have that limiter screw on your throttle cam?

Yes it's there, I haven't bothered to remove it as someone else with a 2015 removed it and made no difference.

You just need to find and remove the looped ECU restrictor connector in the back, under your seat near the tailight, and also remove the screw on throttle cam with T20 Torx tool.

Removing the screw should definitely make a difference, as it will allow full throttle. I would think the versys would not power wheelie with the restriction screw. See if you can power wheelie in first gear with the screw in place. Accelerate to 4000rpm, throttle off to dip the front, and then go full throttle to lift the front. Then remove the screw, and try again. The difference should be obvious.
