... I was surprised to find mine had crept up to 5.3% when I hooked TuneECU up this morning. 2003 Tiger, K&N, TOR pipe, tune 10121.
I'm pretty damned sure it was 4.3% when I last looked. Seems to be running just fine, though a good blip when warm shows a puff of black smoke. Thoughts?
Mine went the other way, i set it at 4.6 went for a run, checked the next day, 4.2 :icon_scratch
beats me but most things do :? :lol:

Thoughts are you're not running your O2 sensor closed loop... lower every single fuel-trim on your AF maps below 14.5... 14.45 or 14.4 works fine.
Then, re-set your LTFT...
This will knock the O2 sensor out of the equation and only run the values you input, so it should never change.
