I am currently running all stock and haven't removed the EGR components. For details on how UltraGuage is working with the EGR system removed, ask Growler. Currently our UltraGauge are using MAF for its calculations and since our first calibration entries, things are looking much better. Time will tell... either way the UltraGauge will work with or without the EGR. It's also my understanding using the MAF is more accurate than using the MAP for calculations.

I know it's been years but do you still like the ultragauge or not?

I still have mine and it is now hooked up to my 2015 GSW DSG.

It does not show boost on this car, but it does tell me the EGT numbers (so I can see when a regen is happening) and the coolant temperatue, I am using it for those functions.

up until april of this year I had it plugged into one of my two ALHs since I got it and it always worked just fine. once you get past the initial calibration process, it just works and stayed pretty accurate for my needs. I always kept good track of my tank mileage on Fuelly and the UG was always within an acceptable tolerance when I was paying attention (mostly during calibration and the occasional tank spot check)

it did get to the point where resetting it every tankful was a bit of a hassle (not sure if it would be an issue on your 2012 jetta, the UG may pick up that the tank got refilled from that car) so I just let it turn into a "lifetime average" and a short trip average.

FWIW its half price or so of an Scangage, but on my 2015 common rail engine I cannot get boost info and since my dash already has one inacurrate MPG counter, I havent felt like messing with a second one to get it accurate.. yet.

Can't believe its been this long but Yes, I still like my UG. After the initial calibration process as Growler mentioned, it just works and stays pretty accurate for my needs also.

I haven't been so good about using Fuelly to kept good track of my tank mileage but I have an app that does and its pretty close. It does everything I need it to do and to date is still providing me read outs.... )

I have the UG Blue (BT/Android). I have had several go-'rounds with calibration with unsatisfactory results. :-(
The UG always worked well with my gas vehicles, but not with my '06 Beetle TDI. I'm back to calculating MPG the old fashioned way and that's been fine.
I just wish I could get accurate MPG numbers with it; it's fun having the other gauges and the ability to customize them.

I love my Ultragauge. It was a real pain to set up properly--you have to follow the directions to the letter, even when they seem nonsensical--but since I got it set up, it's been great. I love the accurate engine temp readout, speed/rpm, etc. And my mpg readings are accurate and consistent over 2 years, in my 97 Passat glx/96tdi wagon.
