I've looked all over the internet but I haven't found a definite answer for this yet
Not sure where to throw this post, but figure this is as good as any.
I see the Android app Torque gives good feedback, Boost, voltage, acceleration etc. However, I am looking at which Bluetooth OBDII device to get, they range from $35-100. I understand the most expensive one is "supported" but is there a risk with using a cheaper version? If you are simply monitoring the engine, I can't imagine it causing problems.
Just wanted to see if anyone is using this.
