Post up your OBD-I fuel consumption via the MPGuino or similar!
 

As well as engine displacment/idle rpm if possible. Just cuz I'm curious! I've read that many older vehicles, even going back as little as five years, see significantly worse fuel consumption compared to displacement and I was wondering if anyone else had an real world experience regarding this. :thumbup:

I have a '92 Mazda b2600i 2.6L Manual. The (Now calibrated) MPGuino states that I get 27.8 mpg averaged over a 50 mile freeway commute. Idle RPM is in the 600 rpm range.

I'll try and remember to post my results once I get my 'guino dialed in. In the meantime, you could look at the fuel logs. I'm sure it would take some time to sort it all out, but that's one source...if I understand what you're looking for correctly.

Doh, I forgot to mention that I'm looking for idle fuel consumption. :o

MPGuino does not have a GPH display on it yet that I know about. It could easily be put in the custom screen from what I have seen. How about it?

Actually it was in the last update.

But I think meatsicle is looking for the data from the EOC/idle screen (left twice from the custom screen)

Ok, since I had to re-program the settings anyway (Weird lockup) I updated. It is telling me .55 GPH in idle, warmed up, lights off, neutral.

Thanks for the info!
