Thanks again to Karl Britz (Karl411) for finding and posting this excellent article by the great Mike Hollar! (Mike Hollar has done much to advance our combined Knowledge re: fuel efficiency and along with Ron deserves all acclaim IMHO)
There is so much great research/reference material about ECU sensor tuning I felt it deserved a place in the Index. It dovetails closely with so much Ron has taught us, and it's concise. I'm adding it as a link to the original article at MPG.org
