The Ultra Gauge EM Plus can display 78+ possible standardised gauges. Gauge selection is completely customisable. The actual gauges available are vehicle dependent. If your vehicle supports any of the gauges listed, then the gauge will be available for display by Ultra Gauge.
The Ultra Gauge EM v1.4 PLUS is a very useful tool for any regular, or tuned vehicle. Where some vehicles come with just a few, or even no dashboard gauges, the Ultra Gauge allows you to access a huge range of live, accurate readouts.
With 78 possible readouts, readiness monitors and performance measurements, this inexpensive gauge is must have. Fitted in less than 5 minutes, this could save your car should you have a malfunction and otherwise have no idea on things like water temperature.

I bought a cheap (sub $10) ELM 327 Bluetooth clone OBD-2 diagnostic adapter on a local "ebay-style" market where the seller specializes in car diagnostics and has several thousand positive reviews (read: I guess this seller would not provide anything really harmful). The adapter is labeled with an "ELM327 v1.4" sticker and the device identifies itself as an "ELM 327 v1.5" over serial. I know v1.5 does not officially exist in the original ELM.
The adapter was able to pair with a European 2006 Volvo XC90. I ran through a few free diagnostic apps (namely 5 of them: Torque free, OBD Car Doctor free, DashCommand, ScanMaster and OBD Auto Doctor) while some of the apps connected to the car successfully to show OBD info, some could not connect. I was using the diagnostics for about 30 minutes.
A few hours later, the car had problems with starting the engine - a kind of "engine error" light flashed on the dashboard, but the car computer (the text display) did not display any problem. The car did not start on the first attempt but it did on the fourth. There was also low fuel in the tank which could have caused the bad start but probably not the "engine error" light (this light then disappeared).
My question is simple - can there be harm caused to any car or its electronics in general by using the OBD-2 diagnostic port? I know one can also write messages to the CAN bus with it but I have no idea what consequences some bad writes can have.
It is highly probable that the reason your car was reluctant to start was that the time you were running diagnostics had sapped some of the charge from the battery. The battery on the car will not charge unless the engine is running.
With certain generic OBD-II port reader dongles plugged into the diagnostic port of the Ferrari 430, the Traction Control System goes offline. This was noticed at a track day by an owner who was using a bluetooth OBD-II dongle for logging.
On the Volkswagen Immo3 security system, new keys are added using a piece of software called Vagtacho. This software uses the OBD-II interface to connect to the instrument cluster and add new transponder codes. This software also allows features such as illuminated dials to be enabled. It works be reading the complete e-prom of the cluster and allows users to poke new values into this data extract then upload it over the top of the existing e-prom. It is possible to do real damage to a car if you get this wrong.
So, in theory, if one of the applications you used with this device tried to perform an unsupported operation which the car misunderstood, you could damage the car. However, this is incredibly unlikely to happen given the activities you have described.
To my knowledge there is no way a scanner can cause issues with your computer electronics. This device is a read only device. It doesn't change anything in your computer. It does, however, communicate with the computer. Through this communication it can give the computer commands, such as to clear the codes. This doesn't write anything to the computer, but rather instructs the computer what to do.
Absolutely. If you hook a welder up and juice the PCM through the OBD with a gagillion amps, you will fry the electronics of the PCM through the OBD port. (NOTE: Would you do this? Probably not on purpose, but it is possible.) If you use a tool to remap the fuel curves within the PCM and pull the cable before the entire remap is written, you will cause damage to the PCM. There are probably a million (on the conservative side) different ways you could possibly damage your PCM or anything on the CAN Bus electronically through the OBD port. The probability of it happening depends on what you are doing and how you are doing it.
It could possibly cause harm, but the probability of this happening is remote. I'm sure there are about a 100,000 of these devices being used out there, by whatever manufacturer. It is meant as a read-only (meaning, it will communicate with the PCM and read parameters) device, not as a device used to reprogram the PCM or other components which ride on the CAN Bus. Could someone utilize this device in such a manner? Yes, no doubt. If you are using the device as prescribed, you have not done any tampering, and you are utilizing the device programming as provided, the chances of anything happening to your PCM or other electronic devices on the CAN Bus are extremely remote. When I say extremely remote I mean the chances are just above nil. If it were to electronically short circuit, anything is possible.
Just this morning I connected an ELM327 to a '05 Volvo XC90. After only 1km, the message was displayed for "Anti-skid service required", and then "Anti-skid temporarily unavailable". I removed the ELM, and went home, and checked the car on the laptop based Volvo VIDA/DICE. This showed a BCM fault, CAN network communication error with SAS (steering angle sensor). It had only a single error count. The car has no history of this fault, and it has not reoccurred after I cleared it this morning. It seems to me that the ELM327 can possibly cause CAN based faults, as it seems happened in the Ferrari example above.
I recently purchased a 'ebay' obd2 dongle. Plugged it into my 06 Mercury mountaineer, to check a CEL code. I was using the Torque app. Drove with it for a few miles and the Wrench symbol came up on my display. Truck went into a limp mode. I turned the truck off, removed the dongle and returned home. Next day used the truck and it was fine. Jump forward a few days later. I plug the dongle into my wife's 04 toyota rav4. Get some real time data, but then notice the VSC and ABS lights are lite up on the dash. Turn the car off, turn it back on and now it has a rough idle and actually shuts off if I don't give it gas. Remove dongle and car returns to normal. Jump forward 2 weeks, today. Plug dongle into mountaineer to read a CEL, bad O2 sensor. Got distracted and leave dongle in. Wife goes out in mountaineer, calls me saying the truck is acting weird and the wrench symbol is on. I told her to shut truck off remove dongle and she'll be fine.
I just had a problem using one of this OBD2 Bluethoot module on my Chevrolet Trax 2015, where my Traction Control System stop working (Engine and TCS dash lights came on), also the transmission wasn't able to shift gears. I even have to push the car back to the parking spot. No air conditioner, no MPH reading, no fuel efficiency info. Unplugged the OBD2 Bluethoot module but no luck. Waited a few hours and everything went back to normal. Dumped the OBD2 Bluethoot module and deleted the app.
I am writing an OBDII app for Android and my extensive testing has showed that Yes it can have a negative impact on the cars performance. I have had test outcomes where all the lights on the dash light up and the engines torque is reduced. I believe this could be related to overloading of the OBD circuitry with constant commands being issued from an app. I'm sure that most/all current OBDII apps out there have undergone extensive testing for this and I would recommend that you do not expose your cars multi thousand dollar circuitry to a $10 adapter that is driven by a $2 app. Maybe look for guarantees and/or evidence of extensive live testing. Most of these apps are written with OBD simulators, which of course will not show any engine/circuitry degradation.
my car was working fine, until I decide to plug in my obd reader while driving on the motorway, where it came to a near complete stop, I plugged it out quickly and took off again, everything seemed fine until I got off the motorway, and was driving in limp mode, I stopped the car and tried reset the ecu, to no avail, so I went to the nearest motor exit with a down ramp and built up a enough speed to get somewhat home, after stopping on the motorway, my car was reving in gear but no movement, until I stuck the obd sensor in and now its back in limp mode and moving.
Xc90, 2008. I was driving and using Torque app and plugin to make a chart for boost/rpm. For 5 km everything was OK. Then i stopped, switched the ignition off and checked my tire pressure for maybe 2 minutes.The car started OK, moved maybe 2-3 meters and then i felt something like kicking or like one tire slipped on the asphalt. Then Antiskid system errors + automatic gearbox switched to limp mode (showing "-" instead of "D").Ignition off, chinese elm327 out of the OBD, ignition on - everything was OK.Then i checked with VIDA for errors:BCM-0115 Communication between control units communication problems with SAS signal missingBCM-0148 Communication between control units Wrong configuration IDTCM-e000 Control module communication Faulty communication
Of course you can damage a car by plugging in a something into the OBD2 port. You're attaching an electronics device to an electronics port. Broken devices can create all sorts of problems, shorts being just one of them.
I just got back from a Kia dealer as I was having a variety of electrical issues with my 2011 Kia Sedona (160000 km). I have a vGate OBD-2 bluetooth adapter and run Torque Pro on my 7" android head unit. The MIL lights that were coming on were as follows: battery and brake light and a corresponding drop in voltage measured by Torque Pro. Then, if the voltage dropped enough, the head unit would power down and restart. A few days later, the ABS, ESC and engine light came on. My speedometer needle started bouncing wildly. At this point, Torque pro started displaying erroneous data for such things as my oil temp, transmission temp and many other sensors. I disconnected the battery for 10 - 15 minutes to clear codes and reset but didn't think to remove the adapter. After a reconnect and restart, all the same MILs reappeared. In short, all errors returned. The Kia tech said that leaving the adapter in for extended periods of time can cause these errors. Removed the adapter and reset the ECU and everything is back to normal. I did a 40 minute drive and no MIL lights returned. So, I believe that leaving the adapters in can cause, minimally, temporary issues. The Kia tech said it's not an issue to use the adapter, but it's good practice to take in out when not in use.
