Hey folks, I’m about to pick up a 2018 yz450 and a Camso kit for this winter, and I was wondering if/when the PR2 is available for it. I’ve heard nothing but positive reviews about the PR2, and seems to really let the bikes run to their potential. Also, if/when using the PR2 ecu, does that mean we lose the ability to use the fancy wifi smartphone tunabiltiy the 2018 YZ’s have ?
So far all I have on the list of mods are handguards, thermostat, engine blanket, and probably a snorkel type intake.
Will probably have to put stiffer springs in the forks yet for my 230lb butt.
Completely new to snowbikes, I welcome any and all info.
PR2 is just a Vortex ECU with their custom maps installed. I have a generic Vortex ECU and saw all the gains that people talk about. PR2 will sell me their maps for $135 but I don't think there is much value in that, I think just getting rid of my restrictive factory ecu was the biggest bump I can expect.
Like others have said you almost positively won't need an aftermarket ECU with that bike. That bike is not locked down and restrictive like the ECU in my bike was (husky 501). For example just putting a pipe on my bike would cause it to run really lean and run terribly (flame outs), but I couldn't just go in and remap the ecu, so I had no choice but to go to an aftermarket ECU if I wanted to run anything other then stock configuration. (I didn't)
With the setup that comes from the factory on the YZ, it is not lean from the factory because they are not trying to make those bikes street legal and can easily be tuned by their built in tuner, so if you do go to an after market pipe and you are running lean, you can go in yourself and fatten it up quite easily
to sum up, ride the bike first, use the built in tuner, if still not happy look at other after market ecus, if PR2 doesn't have a version for your bike a YZ vortex is a good option, if you go this route and later on PR2 make maps for your specific bike, you can buy their maps from them later on.
yes better springs or the add on air compensation tool is what the local YZ guys run. I know on my bike better springs were cheaper and easier to install so I went that route
I would add a thermo-bob or thermostat and then you can use slider panels to block air flow to the rads if you are getting too cold on cold days
