Having that data and the ability to change ECU fuel map and ignition timing maps would give you the same tuning capability as pro circuit racing teams. I don't have a machine with the aftermarket exhaust to compare to, but maybe some can provide input.From what I have read you are better using a wide band a/f data logger than a dyno so you can take the real world numbers and tune accordingly.Ī dyno tune is a simulation and not a very good one at that,tuning with a data logger tells you what is really happening when you are actually riding the bike. Imagine a UTV desktop dyno, it would be a cool app, but probably expensive. Sometimes, the latest & greatest components would either give you a depreciation or improvement in this curve based on the sum of the build.

This would give you a general idea of how your build should perform. You could plug various components into it and get a generated HP/Torque curve. I think the aftermarket exhaust would 'breath' better and hence perform better around the 30-40 mph and up.īack 20-30 years ago, when I use to rebuild engines for fun, I had a desktop dyno. I did the stock exhaust tune and the torque seems increased 0-25 mph a lot and 25-50 mph is more linear. It could be the old school gearhead in me, but I think the back pressure from the stock exhaust gives great low end & mid range torque, but tapers off on mid to top end performance.

I may be forgetting some areas I wanted to discuss, but if anyone that has this ECU flash or Weller Racing wants to mention any points, please feel free to do so. It's Proper Protective Equipment to protect your lips after they put a smile on your face with their product. I now know why they send you a complimentary chap-stick.

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. I could go on about different driving scenarios with my results, but let's end with a quick summary. I don't know how they managed to do it, but this alone is worth it's weight in gold. In fact, throttle responsiveness doesn't get any better in my honest opinion.

Their adjustments in this area not only remove any unwanted throttle fluctuating inputs, but also do not negatively affect throttle responsiveness. Trying to find that peddle sweet spot either while driving on trails or doing controlled maneuvers in the tight and technical.Įven 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. If you have a X2/X4, then you know how annoying the throttle inputs/results can be. 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. As I did several runs by myself, then took the wife and did the same runs again, I had the same results. What was surprising was it performed the same under a 'more load' condition. With Weller also increasing the Rev Limit and the Speed Limit removed along with their tuned 847cc, I did several high speed runs from a stopped position.Įven with the stock exhaust, this motor feels more powerful and responsive.

Plus with Cooling fan activation lowered by 10 Degrees. This tells me that they really hit the spot while also staying within safe operating parameters. 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). The fuel/timing improvements really bring this motor to life with what us motor heads call Peak performance. I feel the Weller Racing tune has really hit the sweet spot on this 847cc parallel twin. 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.Īfter some testing and thought, I wanting to keep my review simple and to the point. I've read reviews of members with the ECU flash with the aftermarket exhaust, but I don't recall any with the stock exhaust.
