I finally got to use TuneECU on Android. Short story I purchased a Nexus 7 tablet off EBay. They can be had for $60-80. Plus an OTG adapter (usb to usb micro) for a few dollars to use a USB CAN BUS adapter and you have all the hardware you need. The final part of the puzzle is the TuneECU app. If you have a 2013+ model you can get the TuneECU Lite version which only suports Bluetooth and diagnostic it costs $4.49. If you have a pre-13 model and want to load maps then get the standard TuneECU app which is $10.99
So I was able to read my map and all my sensors in a compact easy to use tablet. This beats my laptop by a mile. Now I can carry an inexpensive tablet in my toolbox instead of an expensive tablet. It seems to have all the same functions. The only thing I couldn’t find was an ignition map table. Everything else I could recall was there and worked as easy and fast as my laptop. Total cost for everything should be under $100 if your patient and shop. If you already have a cable and/or an Android device that’s supports USB OTG you are most of the way there already.
If you have a pre-13 model you can us a wired connection. You’ll need a VAG-COM CAN Bus USB adapter. Something similar to this. I don’t have this one so I can’t vouch for it.
They look like this.
Now you need a way to connect the large USB connector to the micro usb the Android device has. These are what are called OTG Adapters.
Because I’m using this for track side I wanted as small as possible so I got this style that I can leave in the usb connector all the time.
If you’re trying to use this with a 2013+ model then the only way to do that without locking up your ECU is to connect with a Bluetooth CAN-BUS adapter. This will allow you to do al maintenance and diagnostics but you can not load or read maps off the 13+ models regardless of how you connect to them. The Bluetooth adapter also works with pre-13 models they just don’t support map editing on those models where you can with a wired connection.
This is the one I just got and I can verify it works.
