They have their place. As that they are a one off purchase, compatible with at least the 2006 CRD and give a myriad of information.
They are very capable but the CRD is not blessed with many sensors. Compared to the lights on the dash, the numbers tell me a whole lot more.
SO; I have one - not for long but no issues.
Straight up comms established (connection), subtle mounting with auto power down with ignition off and auto light level settings, I am running a splitter to 2 parallel com ports - one for the general stuff that I will get from the UltraGauge - mine cycles through 15 gauges on a number of screens - is compact and will give me a very good snapshot of what is happening.
If I forget my phone,
I still have data.
ALSO:
I can mount it in parallel with an Elm scan (Wifi) device and smart phone - I know the baude will be lower but I can wear that or if I need more data logged I can a few options .
These vehicle are shy of sensors in the right places.
Plan is to eventually compensate for the extreme shortage of essential sensors through the Kiwi system of daisy chaining desired sensors over and above the hard wired ones I already run like EGT, Boost, intercooler air in and out (dual gauge display). I now have a check on boost. I could treble hook many gauges but the vehicle itself is the limitation.
The problem with the whole vehicle is if you are a data fiend, there are just not enough sensors supplied at the outset to get the most from whatever system you employ against what CJD provided us with.
The Smartphone and Pro Torque App can provide me with data logging and if I need to I can couple the AE in the system for much data logging should I run into trouble...that would give the phone and the AE data logging to let me monitor PIDs that glitch.
It is time for a trade-up in phone to a Smartphone due to family circumstances and this is how I will decided on the SmartPhone.
IMPORTANT NOTE: No evidence yet of the ScanGauge interrupts to a happy and contented ECU.
I now have a device that should serve as an Evic in the Ultra-Gauge package but that it the bit I haven't yet set up, nor the many warnings....but I tend to drive by the numbers which are easy to read and can be positioned at a comfortable level - I have just worked out a change that will allow a mount right next to the instrument panel giving continuity of data panorama.
It is a matter of deciding what YOU want. If I have an issue will go close to knowing what's cooking.
I don't have to touch a mobile phone to get data - and we al know how that is going - but I can if I need/want to and I don't have to carry my laptop with me.
I would've had too many gauges to fill in for those missing sensors.
Rules are harsh in Australia about touching a phone whilst driving.
You do not need to touch an Ultra-Gauge once set up.
