The YOUCANIC UCAN-GO is a Bluetooth 5.1 performance dashboard for your car. It streams live speed, RPM, coolant temperature, engine load, and battery voltage from your ECU to your phone, times acceleration runs, mirrors a heads up display onto your windshield, and logs every drive. It also reads and clears check engine codes. No subscription. Your factory cluster shows you a fraction of what your car already knows. UCAN-GO shows you the rest. The gauge cluster your car should have come with Plug UCAN-GO into the OBD2 port, pair over Bluetooth, and your phone becomes a live instrument cluster reading straight from the engine control unit. Speed, RPM, coolant temperature, engine load, intake air temperature, manifold pressure, throttle position, and battery voltage, all updating in real time. Not estimated from GPS. Not averaged. The actual numbers your ECU is working with, at the moment it is working with them. Three ways to watch your car Gauge dashboard. Analog style dials for RPM, coolant temperature, and fuel rate with a large digital speed readout. Full screen drive view. Landscape twin dial layout with speed and RPM front and center, temperature and fuel rate along the bottom. Live curves. Any parameter graphed over time, so you watch trends instead of snapshots. Coolant temperature climbing on a grade. Fuel trim drifting. Voltage sagging. Time every run Built in performance testing measures acceleration directly from the ECU rather than estimating from GPS. Run [[CONFIRM: 0-60 mph]] pulls and see what your car actually does, then run it again after the intake, the tune, or the tires and compare real numbers instead of butt dyno impressions. The gauges your dash never gave you A real coolant temperature number. Most factory gauges are damped and sit dead center across a huge range, and plenty of modern cars deleted the gauge entirely for a warning light that comes on too late. UCAN-GO shows actual degrees and the trend, which is how you catch a failing thermostat while it is still a $30 part. A tachometer, if your car never had one. Base model trucks, work vans, and economy trims finally get an RPM readout. Live battery and charging voltage. Watch the alternator work. A slow slide in charging voltage is the warning you get before the no start. True speed after a tire change. Bigger tires make the factory speedometer read wrong. UCAN-GO reads what the ECU calculates. Engine load under tow. Load and coolant temperature side by side on long grades, so you back off before something expensive happens. Every drive, logged automatically Trip history records distance, duration, hard braking events, and rapid acceleration counts without you touching anything. Review the drive after a spirited run, keep a record for rideshare and small fleet use, or hand a new teen driver an honest report card. And when the check engine light comes on UCAN-GO reads and clears engine trouble codes with a built in database of 35,901 codes and AI code search that explains what the code means and what to check first. Freeze frame captures the exact sensor conditions at the moment the fault set. I/M readiness monitors tell you whether the car will pass emissions before you drive to the station. Mode 6 shows on board test results before a code ever triggers. Stated plainly: UCAN-GO reads and clears engine (check engine light) codes only. It does not access ABS, airbag, transmission, TPMS, or body modules. For full system diagnostics, active tests, and TPMS programming, that is the UCAN-II-D Pro. Who UCAN-GO is for Enthusiasts who want live gauges, HUD mode, and real acceleration numbers their dash never offered Anyone driving a car whose cluster hides more than it shows Drivers who want to understand the check engine light before calling a shop Parents and small fleet owners who want every trip logged automatically Who should skip it: if you need ABS, airbag, or transmission codes, active tests, or TPMS programming, no Bluetooth dongle does that job well. Go straight to the UCAN-II-D Pro. How do you set up the UCAN-GO? Download the free OBD-AI app for iOS or Android. Plug the adapter into the OBD2 port, usually under the driver side dash near the steering column. Turn the ignition on and pair over Bluetooth. You are watching live gauges in under two minutes. No wiring, no tools, no account required. One note: the OBD2 port stays powered even with the ignition off, so unplug UCAN-GO if the vehicle will sit unused for more than a few days. Not another ELM327 clone Live gauges are only as good as the data behind them. The cheap adapters flooding online marketplaces run counterfeit or trimmed ELM327 chips that drop connections on modern CAN vehicles and return unreliable numbers, which is worse than no gauge at all. The YOUCANIC UCAN-GO is built on a genuine Microchip PIC18F25K80 automotive controller with Bluetooth 5.1 and supports all nine OBD2 protocols. Which vehicles does the UCAN-GO work with? UCAN-GO works on vehicles built to the OBD2 and EOBD standards: United States: 1996 and newer Japan: 1998 and newer Europe: 2001 and newer gasoline, 2004 and newer diesel Rest of Asia: generally 2008 and newer If your vehicle has a 16 pin OBD2 port within reach of the driver seat, UCAN-GO connects to it. Gasoline, diesel, and hybrid Gasoline: fully supported across all model years listed above. Diesel: supported Hybrids: supported Electric vehicles: Most EVs do not report standard OBD2 engine data. Expect limited or no support at all. A note for hybrid owners On a hybrid, the gasoline engine shuts down whenever the vehicle is running on battery power. When that happens the RPM gauge reads zero and engine data pauses, even while you are moving. That is your car working correctly, not a fault with UCAN-GO. How does the UCAN-GO compare to BlueDriver, FIXD, and OBDLink?

No sleep mode. Warranty 1 year YOUCANIC warranty Frequently asked questions Does the UCAN-GO work as a heads up display? Yes. HUD mode mirrors speed and RPM onto your windshield when the phone is placed on the dash, designed for night driving and for vehicles without a factory heads up display. Can the UCAN-GO show coolant temperature if my car only has a warning light? Yes. UCAN-GO reads the actual coolant temperature value from the ECU and displays it in degrees, along with a live trend graph, on vehicles that report it. This is one of the most common reasons owners install it. Does the UCAN-GO show a tachometer on cars without one? Yes. Engine RPM is read directly from the ECU and displayed as a live gauge, so base model vehicles without a factory tachometer get one. Can the UCAN-GO time 0 to 60 acceleration? Yes. Performance testing measures acceleration from ECU speed data rather than GPS estimation. Do I need a separate app to see live gauges? No. The gauge dashboard, HUD mode, live curves, and performance timing are all built into the free UCAN-GO app. Several competing adapters require a paid third party app to display live data. What model years does the UCAN-GO support? US market vehicles from 1996, Japanese market vehicles from 1998, European gasoline vehicles from 2001, and European diesel vehicles from 2004. Vehicles in the rest of Asia are generally supported from 2008 onward. Any vehicle with a standard 16 pin OBD2 port can connect. Does the UCAN-GO work on diesel vehicles? Yes, on European market diesel vehicles from 2004 onward. Does the UCAN-GO work on hybrid or electric vehicles? Limited support Why does my hybrid show zero RPM while I am driving? Because the gasoline engine is off and the vehicle is running on battery power. Engine data resumes as soon as the engine restarts. This is normal hybrid behavior, not a connection problem. Will the UCAN-GO turn off my check engine light? Yes. Read the code, make the repair, then clear the light from the app. If the underlying fault is still present the light returns, which tells you the repair did not hold. Does the UCAN-GO read ABS, airbag, transmission, or TPMS codes? No. UCAN-GO reads and clears engine codes only. For full system access, active tests, and TPMS programming, use the UCAN-II-D Pro. Does the UCAN-GO require a subscription? No. You buy it once and own it. Free app, free updates for life, no premium tier. Where is the OBD2 port on my car? On nearly every 1996 and newer vehicle it is within reach of the driver seat, most often under the dash near the steering column. Some vehicles place it behind a small trim panel or inside the center console. Can I leave the UCAN-GO plugged in between drives? For a vehicle you drive regularly, yes. If your vehicle will sit unused for more than a few days, unplug it. UCAN-GO draws a small amount of power continuously whenever it is connected, because the OBD2 port stays powered even with the ignition off. Will the UCAN-GO drain my car battery? Not on a vehicle in regular use. UCAN-GO draws 240 to 360 mW, roughly 20 to 30 mA, and normal driving replaces that easily. On a vehicle that sits for weeks, a stored classic, a seasonal vehicle, or a car with an older battery, unplug the adapter between uses. It takes two seconds and removes the question entirely. Does the UCAN-GO work with iPhone and Android? Yes, both. What warranty comes with the UCAN-GO? Every UCAN-GO is covered by a 1 year YOUCANIC warranty, backed by our US team in Towson, Maryland. Who supports the UCAN-GO if I need help? YOUCANIC's US based team in Towson, Maryland, the same people who have answered YOUCANIC repair questions for over a decade. Page last updated 08-2026
