If you have a wr450 you need this

Night and day difference. This kit changes the bike. So happy with the power. Be careful removing the stock fuel screw. It has a security torx.

Worth every penny

Bought this unit for my 2015 WR450 to wake it up a little bit and make it easier to start. Made a big difference with the stock map installed and is very easy to modify with the GYTR tuner.

Best purchase

The competition ECM is amazing, feels like I have a whole new bike now. The instructions are simple and easy to follow, this is a must do for the 18' WR.

Awesome Upgrade

This kit really opens up the bike. The throttle is much more responsive and opens wider with the shorter screw. It's pretty hard to beat this upgrade for the price.

2015 WR250F

Best money you can spend on this bike! Also comes with step by step instructions on how to remove the exhaust baffle restriction and air intake restriction. All easy to do for the average Joe.

Unreal improvement

Bought this after a friend bout the tuner and his ecu, unreal improvement the tuner is a must also. Totally changes the bike, best 100 bucks I've spent in a long time

Definitely Worth the Money

Pretty easy to install (especially the ECU) the only thing that the directions don't tell you is that you will need a T-25 security torx bit, not a regular torx bit as implied in the directions.

Installation was aided by removing the header to access the stock throttle screw as this provided more room to work.

Throttle range was greatly increased, and it will be great to start playing around with various programs to see how performance improves.

My 2015 WR450F now starts up easier as well which is an added plus.

Best $100 you can spend

I bought this for my 2017 WR250F. Stock this bike is great but lacks a little bit in low end torque. I purchased and installed the Competition ECU and removed the stock intake restrictor. This is a totally different bike now. The throttle response improved drastically and power is instant throughout the entire RPM range. What's better is all the additional aftermarket performance parts I have added since are getting their full potential. This has been the best money I have spent on my bike.

Must have for wr250f

This ecu and the new throttle stop screw made my wr250f fun to ride. Night and day difference in power and throttle response. Get one you won't be disappointed!

A: As of right now it looks like this will not. We have to correct ones for the 250 all the way to 2018 but the 450 fitment stops after 2015 so something must have changed. the correct partnumber you need is 2GC-E9500-V0-00. That's for the 16-18 WR450
Q: Is it necessary to get new aftermarket exhaust?
1 year 8 months ago
Is it necessary to get new aftermarket exhaust or can you use stock pipe? Right now my 2015 WR250F just has no mid-range and not much low end range for beginner level riding. Will the preloaded maps help address that along with removing the throttle stop? I'm hoping this will enable me to ride slower on the trails when putt putting with the little one!
Q: How do u tell the stock ecu and the gytr ecu apart from each other?My 15 wr450f already has the short screw but I'm not sure if the ecu has been cha.

Q: Does this ECU come preload?ed with a map? will it allow the use of an aftermarket muffler

A: Yes it does come preloaded with a map. If it doesn't work well with your aftermarket exhaust, you may want to use a different map.

If you don't own a GYTR Power Tuner, your local bike shop should likely be able to load a new map for you for free or a very small charge (watch the videos on how to do it, it takes almost no time at all to load a new map).

Also don't forget to buy a set of "security" torx bits to remove the original throttle stop.

A: Yes it comes preloaded with a basic map. It works fairly well too.

And yes, it will work with a new exhaust system.
