Note:
If you buy the $18 ELM knock off from Ebay like I did, the documentation is wrong. A little web searching shows the bluetooth passkey is 6789.

After that it works fine. Lots of choices. The MPG seems accurate for the last tank.
Found that doing 60 or 70 is better than 65MPH. Must be an engine curve thing.
Also learned around 35 is a bad spot for FE, whoda thunk it? Maybe high RPM without lockup?

Thanks for telling us about this. Really nice screen. Way better than a scan gauge.
Reads DTC as well. Looks like my bank 1 O2 sensor 2 is going. The fuel trim is way off the others. Bet replacing it pays for the adapter in a month.
