Determining BSFC map from logged OBD2 data

[theholycow]

Yup, my 2008 VW is almost certainly wideband O2 equipped.

Such concerns are probably the major thing holding me back from spending on a SG now. I'd like to fine tune my driving more accurately than any OBD device can due to being unable to read actual measured fuel rate. I may get one anyway to use for live data from available sensors.

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.

The ranks of the financially embarrassed might be bigger than you think. And the reality of the national debt means we should all feel financially embarrassed (I realize some members of this forum are outside the US; obviously I don't mean you). But I realize that's not much consolation. Anyway, I send you my best wishes for health and prosperity. Hopefully better times are ahead.

I appreciate your kind words.. Thank you.

Our physical health is actually pretty good for our ages right now but several emergency surgeries that somehow ended up not being covered by insurance have left us in poor financial health.. A tip, read your insurance policies carefully and with an extremely cynical eye. In one case whether or not a surgery was covered was determined by a single "and" in a long and complex document.

I'm well aware that we have a lot of company here in the poor house, just about everyone I know is struggling right now.

In the short term I foresee worse times, probably medium term too.. The long term has so many imponderable variables that it really is impossible to make even a SWAG about what might happen.

SG has a load (LOD) instantaneous reading which may be useful in this.

I suspect all of you are way ahead of me on this, but I didn't see it mentioned.

I am trying to figure out how to create a BSFC chart on a motorcycle, where no OBDII interface is present. I use an SG in one car, and really like it. I'm upgrading to the SGII currently.

First post. There is some good info on this forum.
