I'm collecting supporting mods for the Fab9 turbo build on my 13 Club. On my last turbo project I used a Pioneer app radio paired with dash Command and a OBD2 dongle to view gauge right on the radio. It was super clean but a major PITA to get it up and working every time you start the car. The radio would mirror the phone which had to be connected to the dongle and would disconnect when you turned off the car. Ugh. Don't follow the exact steps and no dash command gauges. It was super cool when you did it right.

For this build I'm considering utilizing a Maestro RR with a compatible double din radio and the question is what data will be available from the car's ECU/ OBD2? I like the Maestro RR bc its hard wired to the OBD2 which means I should also be able to have the ECUTEK ProECU Connect dongle plugged in at the same time!

Your 2013 should have just about all of extended PIDs available. My 09 Sport is missing a few, like steering angle. I've been running the torque app on track with nothing but coolant temp, knock retard , and air:fuel ratio. The more things you display, the slower the response time becomes for each channel.

 

Same on my 13 cluv/EFR6758 setup. I just use an android phone and the torque app with the scan tool OBD2 plugin running the Pro Mode 22 PID. Jason and Speeps along with others have done great work on this and it works like a champ.
