Cleaning out my garage and transitioning to KTMs a bit for the next few years.
I have a Vortex ECU on the shelf for 2010-2017 YZ450Fs and 2014-2019 YZ250Fs.
These ECUs do not work with the electric-start YZF models --- they evidently changed the generation on the ECU when updating to electric start.
Mapping-wise, this unit has standard Votex maps for the 2014-2018 YZ250F, but can obviously be reprogrammed by your tuner of choice.
XPR Racing, Twisted Development, and TZR Racing have been good to me on ECUs --- just this to them and get exactly what you want!
$285 shipped CONUS.

The below pic is for the Vortex unit programmed for the 2016-2017 YZ450F for reference. The other unit for the YZ250F looks exactly the same but it will be shipped bare / no Vortex box (cant find it) but WILL have the map list.

Following.
Looking at picking up an 22 YZ450F.
Still have it ?
Is the yz450f ECU still available? DM'd
I still have one of these Vortex ECUs for the 2010-2017 YZ450F and 2014-2019 YZ250F.
It has standard Vortex maps for the 2014-2018 YZ250F but can be reprogrammed to your liking by your favorite tuner / for your specific bike.
This Vortex ECU work on all of the kickstart EFI Yamahas --- but not the electric start models.
$285 shipped --- come get it!

Do you still have the vortex for a yz450f
Still have?
Yes, I have 1 Vortex ECU unit left for the 2010-2017 YZ450Fs and 2014-2019 YZ250Fs.
The unit I have has 250F maps in it currently but these ECUs work on both bikes.
