That's good. Help people understand this stuff. I don't know any production vehicle that would supply a wide-band stock just because of the $$ difference. If our narrow bands are accurate there good enough. The fuel milage issue is at stoich/part throttle(less than 20%). What they run at wide open throttle has little to do with mpg just hp. KTM surely didn't care how accurate they're at WOT settings as my stock map was 11.8/1. Very safe, but not good for hp. I am also wondering about the ignition timing. I don't have much experience when it comes to timing at part throttle settings. KTM maps run alot of tim ing in the area of 50+ degrees at part throttle settings. At some points in the 3-4K range under 20% throttle there is 48-52 degrees of timing. I'm wondering if this could be changed to more fuel and less timing to smooth the throttle out.
