Heast Master G200 update

Really good...figured out this fall that my brother had loaded a new program in the controller a couple years ago (it had a glitch) and he should have recalibrated the O2 sensor afterwards, but didn't...been running that way since, until this past November...seems to be running more efficiently again, like it did the first year...still wasn't terrible like it was, just not as good as it could have been.
