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.
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: Do you have fuel maps for aftermarket exhaust or will the standard tune work?
A: We do have tunes to support the aftermarket exhaust systems. They are now available to select from the drop down menus when ordering as well.
Q: Does this reflash require 91 octane and is there any deceleration backfire as a result of this mod?
A: The flash is optimized to run with 91 octane and minimal deceleration backfire if any at all.
Q: What needs done to make an x2 go 60-65mph? Just a ecu flash?
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 ?
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?
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.
