Depending on which software you use, the ELM327 will give you live MPG. There's lots of software choices for it, many open-source.
Hey, just wondering, what software will tell me my MPG, nothing seems to do so?
I have the ELM327 1.2a
I have a 1994 Honda Civic EX and need to know my MPG, but dunno what software to use, Sorry and thank you. I also have a MAP sensor which I think may be causing programs to not show me, but something must.
I mentioned names of ELM327 programs in a response to you in another thread, so I won't bother here. Regarding MPG readouts...I haven't been able to test them all because my cheap chinese knockoff ELM327 1.2a doesn't work with most of them, and the ones it does work with don't seem to be able to show MPG.
