I have a 2014 ES with ECU dyno tune/flash, Arrow header, modified oem muffler (larger tailpipe with oem spark arrestor assembly removed, screen re-attached), Uni-Filter NU 6235 dual stage air filter & heat tape wrapped air box. ECU flash is the single most beneficial & impactful engine mod for the S10....it will adjust fuel, throttle & deceleration maps, remove the restrictions in the 1st 3 gears <5,000 rpm & adjust the fan on/off temp lower by 10 degrees (eliminating the oem retarded timing that occurs during the oem temp settings) + custom throttle maps (Sport now 1:1 ratio providing crisp throttle response & strong acceleration, Touring mode has been optimized for low speed & in town riding & becomes 1:1 @ 4k rpm eliminating need to change modes should full power/response be wanted/needed). Oem O2 sensors are retained with the 2WheelDynoWorks flash. Flash can be done via mailing your ecu... Anthony Corcella avc8130 on the Yamaha Super Tenere...
