Best Bang for the Buck!

Best mod you can do to your bike for the price. I have a 2014 WR450f . Very easy to install HOWEVER, you need a special bit to get the stock throttle screw out. You need the torx bit with the nipple divet( not sure what the official name is ) . I had one at work that i was able to use.

If feels like a real 450 now. COMPLETELY different bike/power. By comparing the stock throttle screw to the one that came with the ECU. Id say its roughly a 65-70% increase.

Amazing product

Replacing the stock ECU with the programmable one plus removing the throttle stop made a huge difference. I'm relearning the power band all over again, and this upgrade is worth every penny. I had no idea how choked up the stock set up is. You wont regret it. Best spent $100.00

A must have! With this and the power tuner, you can map the bike how you want to ride it, completely opens up the power!

For the love man, get this for your WR!

Unless you like having a 450 that runs like a 250 there is no reason not to get this ECU for your bike. Grab the power tuner while you're at it or at least find a friend that has one. Install was very easy for the ECU, getting to the throttle screw involved removing the exhaust system to get to it, but really no big deal. It has made my bike insane and it starts more easily as well!

Worth ever dime!!!

The moment I fired up my 2012 wr450 I immediately felt the differences without any loaded maps. It doesn't run as lean after I put my q4 pipe on. Still playing with maps and I can only imagine how much more I can unleash the monster out of my engine just because the ECU competition kit!

A must Have

Woke my 2012 wr450f up. Starts easier, throttle response is crisper, and has more power. This is a must have it you want to uncork your WR. Its plug in play took me 5 min to install that's including removing the throttle stop. (throttle stop takes a security torx).

The 2014 Wr450 for sale in Canada has this programmable ecu in it already from stock? Or do I require a gytr?
Do I need this upgrade if I have a Canadian bike?

Your Canadian version already has a programmable ECU. All you need is a gytr programmer.
