Post a link to the one you bought. Others may be interested. I actually have 3 (don't ask me why), 2 standalone and my ScanGauge E also doubles as an OBD2 reader.

I have a Scangauge II that is perminently connected to the OBD port, I use it for the gauge functions rather than the fault code reader.

Me too, but you could if you needed to.

I have one of those small blue bluetooth ones lying about, I think it was around £2.50 direct from China a few years ago.

At the time, I bought it to work with a Ford using the J1850 PWM protocol but it wouldn't connect to the ECU - despite the protocol being listed in the spec. I took it apart and found that the pins weren't even wired up for it - different protocols use different pins in the OBD plug. It does, however, work perfectly with the Jazz.

The car had no MPG-ometer, so I was going to set up a similar device to the Scangauge, connecting it to an Android app such as Torque, or there are some other apps which are very similar indeed to Scangauge. The OBD hardware for the Scangauge is basically one of these, connected to a bespoke unit with the software and an LCD display.

I have collected various diagnostic tools over the years, all clone type laptop cables for VW/Audi, Nissan, Peugeot/Citroen, etc., and a couple of generic OBD readers too. I couldn't begin to guess how much these have saved me over the years.

Although those cheap generic ones will only access live engine data and trouble codes, and not the other systems on a Honda such as ABS, gearboxes, etc., I would say it would be the best £3 you will ever spend.

I have a Bluetooth dongle, but had issues trying to get it to talk to my laptop. I also have one of these,

but have never needed to use it.
I don't have a Smart phone, in fact it is barely a couple of IQ points brighter than me.
