Added the Banks iDash SuperGauge using their lower mount grab bar Stealth Pod. Really easy, really clean install.
Being connected to the ODBII port, much like a JScan, not only can it read codes without having to turn the Jeep off and go into a diagnostic mode (like is required by the Tazer), which can cause some intermittent codes to disappear (such as what happened to me on my old JL when the locker sensors were acting up), but it can also display up to 8 vehicle parameters at a time (from a selection of up to 300 parameters, depending on the vehicle). So, I've currently got it setup to show Engine Coolant Temp, Engine Oil Temp, Trans Temp, Oil Pressure, Battery Voltage (the 5 gauges that display on the Off-Road Pages app), as well as Ambient Air Temp and RPM. It also has a programmable "shift light" (which I've set to bright red) where you can have it alert you to shift when approaching a certain RPM; in my case, it's great because when I want to "bark" the exhaust on a shift at high RPM when I'm driving by the back of the former HOA president's house, I see a red light in my periphery and I don't have to take my eyes off the road.
Banks really did a nice job with the Stealth Pod. Has that factory stippling look to it, and fits securely in the grab bar. I did have to remove the lower CMM mount I had there, but I have a CMM mirror mount on the upper side of that grab bar, with a ball mount, so not a big deal.
