Good thing I warned you, eh!
RSR 555 wrote:Can do. According to app info, I'm running 1.8.199 I'm guessing that is the latest?
Yes as far as I can see. Here is the
Torque changelog page. Note the next release (beta 1.8.202) will log the 'events' (fault codes) in a separate file- should be useful.

Actually generally it shouldn't be accessing the "ROM" (Read Only Memory) ços that's where the programming is stored. The OBD-II should be accessing the various parameter variables stored in RAM that constantly change. And yes, these should be "readback-only" although you may be able to program (write) them through proprietary protocols.
However as the OBD-II port is mandated and set up in every car since ~2004 in Oz (and earlier O/S) and OBD-II only specifies a certain number of the pins for its use across several protocols, naturally the manufacturers used the already supplied port using the other pins for their own proprietary comms. Alternatively they can use different protocols/speeds on the same pins so long as it doesn't interfere with the OBD-II data.
Because the manufacturer can access the car, your appropriate software and hardware (your Snap-On scantool for example) will access these proprietary protocols so far as it is able. These give access to all the modules in the car and usually allow reprogramming, modification, ROM flashing/upgrades, etc. It is quite possible to 'brick' your car electronically if you do the wrong thing! See for example for Subaru
Scoobyrom and
romraider, both of which I never got into.

I agree it is unlikely that the bluetooth OBDII dongle will allow more than one connection (not sure though) but other Bluetooth devices can and do...including car ones. I have had both my phone and tablet connected to my Jabra standalone unit in my older Mazda 3(phone for, well, phone and tablet for music relay through FM to the stereo) and I think I've had the tablet/phone combo again connected to my newer Mazda 3's head unit.

If by icrap you mean Apple devices, then I don't like them either

BUT firstly they do run Bluetooth and secondly the generally are more tightly controlled than Android devices. Bluetooth is merely a data communications protocol/method between devices just like wifi. What is transmitted across it depends entirely on the devices/applications using it. The main issue with wireless protocols is they enable you to access something without physical access. So if there is a security flaw in a system then someone could access the vehicle without actually gaining physical access to the vehicle. Also they can execulte the wireless equivalent of identity fraud- listen to your communications and 'spoof' (imitate) them, hijacking your communications. Not that I think this is likely unless the KGB/FBI/worse is after you!
Also remember that cars do have to be 'on' all the time now to a certain extent- for example they must 'listen' for the remote fob transmissions to unlock the car. They must monitor other functions. For example, our Mazda 2 runs various motors after stopping & locking dependent on what's hot- one is the cooling fans, the other is (I think) a transmission cooler pump after I've caned the car around the local hilly area.

I'd like a Dolomite Sprint myself. Noticed a couple on gumtree in WA recently too.
