Since adding the corn I've only been seeing readings of up to +1.5 here and there and not every time I go WOT. I'm much more comfortable with that than the consistent +4 on every WOT.
Thanks everyone for all the help, it's greatly appreciated.
Your calibration has slightly over advanced timing for the fuel it was setup for since adding ethanol reduced the KR.
But I would've have stressed about it anyway, that's why the knock sensors are there
If your mycal device has end user options like SCT you could pull a couple degrees globally instead of having to add ethanol all the time.....That's really a bandaid anyway since your tune isn't really setup for higer E content. The more E you add the more your stft's and ltft's will deviate since you are changing the stoic point of your fuel.
