vLinker MC+ Bluetooth OBD2 Car Scan Tool for iOS, Android, Windows

I have a JL Wrangler which suffered from a glitch with the auto headlight function after using FlashCal. The Vgate vLinker MC+, when combined with JScan, fully resolved the issue. The device itself is easy to use. With Bluetooth Low Energy, I didn't even have to pair it using traditional Bluetooth. You just plug the device into the OBD-II port, then launch whichever diagnostic app you have, select the BLE option and it connects within seconds. It's small enough that I can just throw it into the glove box or the center console and just dig it out again whenever I need it. It was fully compatible with my vehicle and I was able to change a lot of functions using it--far more so than I could do with FlashCal. It worked pretty well, although there were a few hiccups when trying to save some of the altered settings where the app became stuck while trying to save the changed settings, but I was able to resolve that issue by restarting the app and cycling the vehicle's ignition state. Note: For any 2018 and newer FCA/Stellantis vehicles, you will need to have the Security Gateway (SGW) bypass module connected to make any programming changes. That's not a limitation of the vLinker or JScan. That's just FCA/Stellantis gatekeeping everyone--even dealerships--from accessing the computer system in their vehicles for free. The official product that FCA/Stellantis dealerships have to use is wiTech, and aftermarket programmers need AutoAuth to unlock SGW, and both of them need annual subscription. You can find SGW bypass modules on Amazon for about $30. If you own a JL Wrangler and have issues where you have malfunctioning auto headlamp feature, I have the tutorial on how to fix that issue below: FlashCal and Tazer users, including myself, have reported the two products introduce a glitch with the JL Wranglers' auto headlight function, where the headlight will automatically turn on when the ambient lighting is low but refuse to automatically turn off when it gets bright, which commonly happens when you're driving through a tunnel or at an extended stop under an overpass. Some people have suggested replacing the ambient light sensor by the windshield, which I tried and that did not resolve the issue. What seems to happen is when you use FlashCal and Tazer to change any of the settings, they seem to cause a bug where invalid value is entered for how the BCM reads the voltage from the ambient light sensor. The way the ambient light sensor works for JL seems to be resistor-based where being exposed to brighter ambient lighting will cause it to read lower voltage and vice versa. FlashCal and Tazer do not have a way to read and adjust the data to and from the ambient light sensor. JScan, on the other hand, goes fairly in-depth with not only reading the voltage but allows you to adjust, as well. After you plug the device into the OBD-II port, you can use Bluetooth Low Energy on your phone to establish connection to the JScan app. That only takes a few second, and you don't even have to pair the device to your phone. 1. Go into the "ADAPTATIONS" menu 2. Then access the "AUTO HEADLAMP & AUTO HIGH BEAM SETTINGS" 3. For "Auto Headlamp OFF Threshold", the factory default value is "2.80V" 4. For "Auto Headlamp ON Threshold", the factory default value is "3.60V" 5. Scroll all the way down to "Twilight Sensor / Light Sensor / Tunnel Detect On/Off" and ensure it is set to "Active" Following the instructions above should restore full functionality.

Product: Vgate vLinker MC+ Bluetooth OBD2 [bought Jan 2022] $60 Car: Mazda CX-5 2021 Test: OBD software 'FORScan Lite' v1.5.12.1 on 2 mobile phones [Android 12 & Android 10] I thought there was a problem as, after following the instructions to pair phone with BT [i.e. select "vLinker MC-Android" in phone BT 'pair new device' settings], it prompted for the code [1234], then the BT would seem to connect...then disconnect about 2 secs later [according to phone] :-(. I was expecting it to stay connected [& now clicking the 'connect' button on phone BT does nothing] Turns out this BT disconnecting is expected - the above pairing defines a new BT adaptor config in phone [for the MC+] and you now have to set your OBD software to use this config i.e. in my case run the FORScan software on phone then select 'Settings' / 'Bluetooth adaptor' & choose 'vLinker MC-Android' [I left 'Settings' / 'Connection type' as 'Bluetooth 0']. When you click the FORScan icon to connect to MC+, it will then start this BT connection - only need to do this BT pairing once I think VGate should update their instructions to indicate the BT disconnect is correct/normal [I almost returned mine] FYI 1: When connect the MC+ to car socket, the MC+ power LED lights up solid red & the BT LED goes on/off every second [i.e. indicates that BT disconnected]. When click the button on front of MC+ [to enter BT pairing mode], the BT LED flashes rapidly [several times a sec] until pairing complete [then goes back to the 1 second on/off i.e. disconnected]. When connect with FORScan, the BT LED is solid blue [i.e. connected] - the OBD and Host LED flash rapidly only when pulling data FYI 2: I can use BT to pair the phone to the car infotainment [e.g. to play music from phone to car] at the same time as FORScan is pulling live data from MC+. This may depend on phone FYI 3: The FORScan software is only intuitive once you get the hang of it e.g. run it & BT connected to MC+ but NOT active [don't click the button that looks like play] so can then add items [called PID's] to monitor [e.g. speed, revs, oil pressure/temp...there are literally hundreds] - after adding PID's, only then click the play icon to actively get the vals of these PID's from car i.e. can't add PID's when in play mode I'd expect other OBD software to work similarly i.e. need to pair MC+ to phone & then change the software config to use this connection. Remember, although the MC+ should work on most modern-ish cars [US >1996, Euro cars > 2004, OZ/NZ > 2006 etc] and some light trucks, the OBD software you choose usually only fully supports [i.e. a large range of PID's] on very specific car make [and to a lesser extent model/year] e.g. FORScan is for "Ford, Mazda, Lincoln and Mercury vehicles" I got this OBD scanner as vLinker series seem to be well supported by OBD software [so less chance of 'issues'], it supports additional protocols [future proofing & use on other car makes], can connect using android/iOS/laptop [only tested first], and has a faster transfer rate [baud equiv of 500kbps - about double that of cheaper OBD readers] Overall, the MC+ seems to do what it says on the tin!

Worked flawlessly w my 21 Grand Cherokee L was able to see all modules that auto zones scanner couldn’t even see. And can even work with electric car to provide live feedback to a better rote planner to exactly plan and update during road trips

Item received as new, all works as intended. Connected to IPhone13 without issues

Good Bluetooth obd2 adapter. No issues with connectivity on my 24 JT on my 23ultra with Jecan. Bluetooth connects fine and able to change settings and feature no hang ups or issues.

This thing is awesome for a diy hacker wanting more out of my older daily driver. I have a 2010 base model Corolla that I drive the crap out of. One thing I love about these low-tech cars is that it's a blank canvas to have fun and not worry about resale value - not like this thing affects that. I have a old surface pro 3 that i've rigged up as my interface for the car. Wanted to take the car integration part to the next level and this OBD2 tool lets me do exactly that. I'm not a software engineer, but lets say I dabble. I can't write anything meaningful on my own but AI like Gemini fills in the blanks for me. I wrote an awesome python tkinter based dashboard for my surface pro that lets me see all sorts of fun things like speed, tach, temperatures of engine coolant and even transmission temp! MAF sensor gives me instant MPG estimation. I can even see my individual tire pressure values when my car only has a light that says when something is low! I have not had a problem with connectivity once I figured it out. For Windows 10, the key is to pair it (even though it says android) with 1234. It just worked right out of the box for me with what I wanted to do with it. If you are a diy kind of person and isn't afraid to throw some vibe coding at it, you can have a lot of fun with the data and create something cool. That's what i wanted out of it and that's what it gave me. If that is you, then buy it. Can't speak for the other stuff like pairing it with existing apps or whatever. But its easy to use for me! Compatible right out the box. Love it!!

Complete waste of money and time. Will not connect to phone or laptop via Bluetooth. Requesting complete refund.

I bought this while preparing for a road trip, the first one attempted in my small electric SUV, for use with A Better Route Planner. Pairing it with a phone is a little different, depending on which app it will be used with. I was very pleased to see the little booklet containing QR codes linking to the process description for each app. The one thing I had trouble with was finding the actual OBD port! A quick Google search pointed me in the right direction (far quicker than the owner's manual). As far as I could tell, the device worked flawlessly, reporting the battery SOC and temperature. The app performance, however, was not flawless, but worked well enough to plan all the required charging stops. At least one website talking about using this device with ABRP said to be careful not to leave it connected when the car was not in use as it continues to use a small amount of energy, even when the vehicle is turned off. Naturally, I forgot that and left it connected overnight a couple of times. However, in my case, it was no problem!

It absolutely exceeded my expectations!!! The Dodge dealership was going to charge me almost $600 to reset my ecodiesel’s computer after we installed a new DEF supply line & injector, but this little beauty and the JScan app on my iPhone reset it & turned off the “countdown to no start” for a total of $105!! It uses the SAME technology as the dealership for a fraction of the price! Does live scans, erases codes, diagnostics, & SO much more!!! If I could give it 10 stars I would!

Muy buen producto, lo conecte al coche parado y arrancado y usé autodoctor y va genial. Se pueden borrar y leer fallos con código correspondiente. Llego rápido y perfecto

Excellent OBD scanner at a brilliant price. I considered this against other scanners and for the price of the listing it was a great deal. The vGate vLinker MC+ connects quickly and performs read/writes operations at a blazingly fast speed which is great as I'm not sat there concerned how long it is taking. Obviously, you'll need a dedicated app to interface for your car's system - don't expect to just plug in, download any random app and get going - do your research! For example, FORDs like FORSCAN, Bimmerlink for BMW, Jeeps work with JScan/Alfa OBD, etc... You're paying for the wireless scanner that the app uses to communicate with your car! With that aside, it instantly connects to my phone when powered, and has native compatibility with many apps, the manual even comes with a little booklet of apps to download. For me, it connected with JScan for my 2021 Jeep Renegade with ease and was able to read all codes, OBD information, etc, and was able to write data to the system too (to enable hidden features, etc. note FCA vehicles 2018+ need a security bypass module). Overall, 100% worth the money, a must get even for the minor car lover, great to just leave in the boot just in case you need it some day.

Really nice works really well on an Id.5 and car scanner and a better route planner

Did what it said a d easy to use!
