I have the Vortex ECU from PR2 on a 2016 KTM 450 XCF with 490 big bore kit. Have been running powder map 7 with fuel settings at 5, 5, 7 for low, mid and high. This recommendation came from a shop in BC where they ride at lower elevation compared to my location in the Rockies. I'm usually riding at 7500ft to 10,000ft. I feel like there should be more power and snap on the low end from the big bore and have heard of people running leaner settings on their Vortex ECU in the area (eg 2, 3, 5 for low mid high settings on powder map 7). Wondering if anyone else has recommendations for vortex settings with big bore kit at similar elevations?
Can you use an O2 sensor or EGT sensor with the Vortex ECU to get realtime adjustments as you change elevation? or at least use it to tune the settings to avoid going too lean.
