This ECU flash is well worth the money even on stock vehicles as the lower fan activation temps, bypassed speed limiter, and reworked drive-by-wire adjustments benefit any X2/X4. You will notice better power in high load situations such as going uphill. I recommend doing exhaust and the flash first before any clutching if you plan on changing exhaust.

2019 X2; Stock Exhaust; Stock Clutch I wanted to keep the stock exhaust for the quietness, so I didn't think I would see the significant gains as others with aftermarket, hence I regressed from purchasing the flash upgrade. I could not of been more wrong. I feel the Weller Racing tune has really hit the sweet spot on this 847cc parallel twin. The fuel/timing improvements really bring this motor to life with what us motor heads call Peak performance. This performance is noticeable throughout the entire RPM range and I don't notice any symptoms or indications of LOP (lean of peak) or ROP (rich of Peak). This tells me that they really hit the spot while also staying within safe operating parameters. Plus with Cooling fan activation lowered by 10 Degrees. Even with the stock exhaust, this motor feels more powerful and responsive. What was surprising was it performed the same under a 'more load' condition. As I did several runs by myself, then took the wife and did the same runs again, I had the same results. The Throttle and Drive by Wire adjustments also contribute to the above performance a lot, but I also want to touch on a few other noticeable areas. If you have a X2/X4, then you know how annoying the throttle inputs/results can be. Trying to find that peddle sweet spot either while driving on trails or doing controlled maneuvers in the tight and technical. Even though I own and love my Throttle Max peddle for the comfort it provides and helps with the throttle issue as a 'work around', the Weller Racing tune has completely resolved any issues I had. Their adjustments in this area not only remove any unwanted throttle fluctuating inputs, but also do not negatively affect throttle responsiveness. In fact, throttle responsiveness doesn't get any better in my honest opinion. I don't know how they managed to do it, but this alone is worth it's weight in gold. I could go on about different driving scenarios with my results, but let's end with a quick summary. I feel the Weller Racing ECU Flash has not only tuned the engine to Safe and Peak Performance levels, but manages to take the driver inputs and synchronize everything together to give the driver the best experience.

Did the Weller Racing ECU flash upgrade along with an HMF Titan QS exhaust, I am very pleased with the noticeable power increase. I added heavier tires and thought a little power bump would be nice, with Weller's plug and play ECU re-flash it gets no easier. great communication from Weller, they answered all my questions. Worth it!!!

Questions and Answers
Q:
Does this flash add more HP to the wheels with all stock set up. Also what is the top speed with the stock 26 inch tires? Thanks for the help.
Asked by:
Ryan
- 10/5/2018
A:
With stock clutching and tires we saw the max speeds come in around 56-57 mph without having to increase the RPM limiters to unsafe levels. Minor power increase with all stock vehicles but we are able to improve on throttle response maps.

Q:
What needs done to make an x2 go 60-65mph? Just a ecu flash?
Asked by:
Kevin
- 10/31/2018
A:
With the ECU flash the vehicle in all stock form (tires, clutching etc....) will run to about 57-58 mph. With oversized tires you will gain speed but it all depends on the size you decide to run. With our machine running 28" tires we are able to reach speeds of 63 mph on the stock clutching. Clutching modifications will be made available as well in the near future to allow added speed as well.

Q:
Interested in what to expect with the exhaust and ECU flash. Running stock tires right now but am looking to go up to 28". Is the clutch kit from Yamaha sufficient or do you recommend something different ?
Asked by:
Jon
- 12/18/2018
A:
Going to 28" tires and then pairing with the ECU flash/Exhaust will offset any power loss you would have with the tire change. The kit from Yamaha comes with some pretty light weights which generally cause the RPM's to run on the high side. With the added power from the Exhaust and Flash the vehicle will actually perform better with the stock weights over the Yamaha oversized tire kit.

Q:
Are there any downsides to a 2018 wolverine 4SE that I can expect such as noisier operation, or rough running etc that I can expect?
Asked by:
Lynn
- 12/31/2018
A:
With the ECU flash we do not reprogram any items that negatively effect the operation of the vehicle. The cooling fans are activated sooner than they are from factory settings so you may notice they run sooner than before but they will not increase the noise of the vehicle. Fuel/Timing tables have been adjusted slightly for a better air/fuel mixture which does allow the engine to also run slightly cooler but will not cause any rough running symptoms.

Q:
I have a x2 on order I also ordered it with 27" x10 tires on 14 inch wheels/ and I am having the clutch kit from Yamaha installed before I pick up the side by side. Is the flash still a good Idea. I saw on another post that stated the clutch kit wasn't needed.
Asked by:
Bert
- 3/2/2019
A:
The clutch kits from Yamaha are a bit on the light side and cause the RPM's to run a little bit on the high side so you notice the engine noise quite a bit more. We still are able to modify and improve on the stock ecu tuning however even if this kit is installed.

Q:
Does this completely remove the speed limiter or just raise it? I think mine tops out at 52mph. I would like to be able to do 55-60.
Asked by:
Ryan
- 4/7/2019
A:
We do remove the speed limiter completely which then limits the speed only by RPM's and allows us to see the additional increases.

Q:
purchasing big gun evo u exhaust and want to know if the ecu reflash will work with this exhaust and if i needed to purchase the big gun cdi or is the reflash good enough. also will be getting the jbs clutch kit and will be running 29-30" tires
Asked by:
Michael Lightell
- 2/19/2019
A:
We do have tuning written for the Big Gun exhaust and it will also work with stock or modified clutching. Within the ECU we are able to modify more areas to allow more power and response than just the standard fuel controllers can access.
