There are a few little oddities that one has to remember. I don't know if these are unique to my brand, or common to OBD II readers. First, if I leave the OBD II tool plugged in continuously, the Check Engine light will not come on when there are new codes. You have to unplug the tool between uses for the check engine light to work. Second, for the device to work, there is a specific sequence that must be followed, when plugging in the device, turning on the ignition, and making the Bluetooth connection with my smartphone.
The other downer for some, will be that this device will not work with Applie (iOS) devices. They have never went to the expense of certifying their device for iOS.
Mine only cost $13, but when I just looked on Amazon, it is now listed for $23. But I've seen what looks like the same device, but with a different brand label, priced for about $11.
Too bad that the one you got already quit working. Hope you can get one that works for you.
I actually ordered a bafx one last night, it appears that there's quite a few negative reviews for the vgate one I got. There was something like 500 good reviews and almost 200 bad ones. I did a little more reading on it and it's a cheapie Chinese clone of a better device. Must have just got a dud.
When it did work for all of 5 minutes it was pretty useful and something I'd like to have to monitor coolant temp, manifold pressure, instant mpg and such. Even put a bracket on my dash so I can see it easily without taking my eyes off the road.
I looked at getting an ultragauge but heard tons of great things about the bluetooth setups, my brother has one and it works great and they're much cheaper.
Hopefully the bafx device functions as it should.
