Determining BSFC map from logged OBD2 data

[fumesucker]

I guess I'm guilty of assuming that anyone who really needs to save on gas lacks the financial wherewithal to purchase one of the newer vehicles that have wideband sensors.. That's why I didn't address wideband sensor equipped cars in my last post.

Other than some of the lean burn Hondas I'm not sure all that many cars which the financially embarrassed community to which I belong have wideband sensors. Frankly, when you don't have a lot of money it's hard to put yourself in the shoes of someone who does.. Thanks to astronomical medical bills my wife and I have no serious hope of ever getting out of debt and I'm guessing that most people who are really serious about saving gas are also part of the forgotten lower middle class in America.

Mea maxima culpa.. It simply didn't occur to me to include wideband sensor equipped cars in my thoughts.
