Digital monitoring system a compromise with interior aesthetics & functionality?

A big NO! The integration of digital monitoring systems enhances the driver’s experience without compromising on aesthetics.  In my opinion, Digital gauge displays are more compact than analog gauges & hence offer better visibility to the driver.

Despite proving my point, some may disagree with me on the aesthetics but in terms of functionality, a Digital gauge display does a home run!!  They also offer customization options that allow drivers to tailor the information they want to view.

Digital Gauge Display vs. Analog Gauge Display: Finding the Right Fit

In the world of car displays, the digital vs. analog debate has raged on. We get it; it’s like choosing between a classic vinyl record and the latest streaming service for your music.

Digital Gauge Analog Gauge
Precision and Accuracy?  Intuitive understanding?
Customization options? Durability and less tech fuss?
Real-time data at your fingertips? Minimal distraction on the road?
Crystal-clear readability day or night? Minimal distraction on the road?

But why choose sides? Many modern cars now blend both worlds, offering the best of both digital and analogue. It’s like enjoying your favorite old-school vinyl with a streaming library at your disposal.

In the end, it’s about what suits your driving style and preferences. So, let’s put this debate to rest and embrace the best of both dashboard worlds.

Now without further ado, let’s jump in!

1. Lufi Xf

I recently purchased the Lufi XF OBD2 gauge display for my car and have been really impressed with its performance. 

The device is compact and easy to install, plugging directly into the OBD2 port in my car. It displays a wide range of information about my car’s performance, including speed, RPM, fuel consumption, and engine temperature.

One of the things I like best about the Lufi XF is its customizable display. I can choose which information I want to see on the screen, and I can even change the color and layout of the display to suit my preferences. 

The device also has a built-in alarm system that alerts me when certain parameters, like engine temperature or fuel level, fall outside of normal ranges.

I can’t count the number of times the RPM alarm has gently reminded me, “Hey, slow down there!” It keeps my engine in its sweet spot, preventing me from redlining or chugging along. My engine has never felt better.

The device is also capable of performing speed test. (0-100, 0-60)

Functions

  • Full OBD-II read & clear functionality
  • Display vehicle info (highly dependent on your vehicle’s model & make)
  • Great customization options
  • Does not come with an inclinometer
  • Does not come with tunes
  • Comes with a dashboard mount
  • Ready to plug and use.

Pros

  • A reputed brand, which means better build quality & customer support.
  • Great Compatibility with American car brands. (2008 and older)
  • Highly customizable.
  • Accurate readings
  • Includes a built-in OBD2 scanner.

Cons

  • Costs a bit expensive.
  • Looks a bit ugly.
  • Does not support Oil pressure/temperature.

Compatibility

I tried but could not find any customer’s review complaining about compatibility issues.

It is best advised to contact their customer support through email or ring them a call. 

Data Visualization

As mentioned earlier, Lufi XF offers great customization & multiple interface options to select from.

You can also customize the color theme of the speed cluster.

Real-Time Monitoring

Lufi XF is a high-accuracy tool, that offers multiple real-time data at the fingertips of the driver.

For me, the most useful data types were;

  • Water Coolant Temp
  • Turbo level
  • Fuel avg (interchangeable from Km/L to Miles/Gallon and vice versa)
  • Avg Speed
  • RPM
  • Trip mileage
  • Battery voltage

Connectivity

Lufi XF, just like any other ODB2 gauge display, can only be connected to your vehicle through the OBD2 port. 

To not have its cable hanging all over your dashboard, it is advised to first mount this device to a desired place & then unscrew the bottom side panels of the dashboard inside which you can hide the cables.

Also using Zip ties will also help to tidy up the wires so it does not hang loose.

Additional Features

A built-in OBD2 scanner & code-clearing functionality make the Lufi XF a top choice amongst car enthusiasts.

Note: 

  • US-branded cars using the J1850 protocol before 2006 are not compatible
  • Engine and gearbox oil pressure, oil temperature, only a few cars have displays, if this is the key reason for your purchase, please choose another single-function meter (don’t buy LUFI-XF)

2. Lufi XS

For transparency, please note that some of the links on this website are Amazon Associate links. This means that I may earn a small commission if you make a purchase through these links. The use of such links comes at no additional cost to you.

Lufi justifies the price of it by marketing it as a 3-in-1 product. 

  1. It can operate as an OBD-II scanner, to view & clear DTC codes nothing special, almost every other OBD-II display gauge provides this option
  2. It can display a few helpful info about the car like the coolant temperature, RPM etc., which is again, nothing special.
  3. The Lufi XS can also operate as an inclinometer, an inclinometer tells you whether your car is inclining sideways, or forward or backward. 

In my opinion, I never had a moment where I had to use the inclinometer, which mean, to me, it was pretty much useless. 

I mean, for someone who daily drives his car from home to work, who cares about checking up on the inclination of the vehicle?

Other than that, another important thing that I felt was good about Lufi XS is that it is more sleek & compact than its twin (Lufi XF).

Its shape & size make it look like a go-pro/dashcam for someone who is viewing from the front.

Functions

  • Full OBD-II read & clear functionality
  • Knockoff version of KONNWER KW206
  • Temperature/Voltage alarm if it exceeds unwanted level. (can be adjusted)
  • Mix opinions on compatibility. 
  • Fewer Customization options available.
  • Comes with a dashboard mount.
  • Ready to plug and use.

Pros

  • A reputed brand, which means better build quality & customer support.
  • Great Compatibility with American car brands. (2003 and older)
  • Highly customizable.
  • Accurate readings.
  • Includes a built-in OBD2 scanner.
  • Includes a built-in Inclinometer.

Cons

  • Costs a bit too much for a Gauge Display device.

Compatibility

Lufi XS or in fact any other digital gauge display works best on newer vehicles (generally newer than 2003-8) 

Once again, It is best advised to contact their customer support through email or ring them a call. 

Data Visualization

Just like Lufi XF, Lufi XS offers great customization & multiple interface options to select from.

Real-Time Monitoring

Lufi XS is also a high-accuracy tool, that offers multiple real-time data at the fingertips of the driver, with a few data in addition to with Lufi XF.

For me, the most useful data types were:

  • Inclinometer
  • G-Force
  • Water Coolant Temp
  • Turbo level
  • Fuel avg (interchangeable from Km/L to Miles/Gallon and vice versa)
  • Avg Speed
  • RPM
  • Trip mileage
  • Battery voltage

Connectivity

Can be connected wired to the OBD2 port.

Additional Features

Other than having the option of reading and clearing OBD2 codes, the Lufi XS also has an option of measuring the inclination of the car while driving, this helps to determine whether the hill/downhill is too steep/up-straight for the car.

3. KONNWEI KW206

This KONNWEI KW206 is the cheapest of all the tools that I will discuss in this review article. The best thing about this gauge display is that it offers better compatibility than the Lufi XS & XF.

KONNWEI KW206 is listed on Amazon at around USD59-60, with a decent positive review about it on their official listing.

Personally, there were two things that I wish I could get along with this tool:

  1. A better screen-to-body ratio. 

For me, the rounded edges of the KW206 seem to serve no purpose at all, it would be a lot better if KONNWEI could either remove the part where there is no display screen or either add a display screen which fits the entire front-facing part of this tool. 

  1. A Touch display instead of buttons. 

Having buttons on the top of the device makes it almost unusable while driving. Plus who uses button-operated devices anyways?

Other than that, for a 60 dollars tag, I don’t think there should be much room for complaints, but hey! 

Functions

  • Full OBD-II read & clear functionality
  • Better compatibility than Lufi
  • Does not comes with an inclinometer
  • Does not comes with tunes
  • Comes with a dashboard mount
  • Ready to plug and use.

Pros

  • Great Compatibility with American car brands. (2003 and older)
  • Accurate readings

Cons

  • Chinese knock-off brand, which means low build quality
  • Poor customer support
  • Reportedly turns off on its own while car is running
  • Display screen is small compared to the size of the device itself.

Compatibility

KONNWEI KW206 has moderate compatibility with American & European car brands, I personally had a decent experience with this tool on my cars. To ensure compatibility with latest car models & variants, it is advised to update the KONNWEI KW206 straight up before plugging in the car.

Data Visualization

Compared to the Lufi XF & XS, the KONNWEI KW206 does not offer enough customization options to improve the user’s experience. I believe the device was not budgeted in a way to give the customers a tailored experience.

Real-Time Monitoring

For me, the most useful data types were;

  • Water Coolant Temp
  • Fuel avg (interchangeable from Km/L to Miles/Gallon and vice versa)
  • Avg Speed
  • RPM
  • Trip mileage
  • Battery voltage

Connectivity

KONNWIE KW206 can only be connected to the OBD2 port of your vehicle with the cord that comes along with it in the box.

4. VJOYCAR V70

The VJOYCAR V70 is no different than the KONNWEI KW206, it also offers decent compatibility with U.S-based vehicles.

I’ve used this device on my 2005 Nissan Patrol & my 2015 Ford Raptor to make sure, there is one thing that needs to be mentioned here, and that is that it might not fetch all the vehicle info you could with a bit expensive tool. 

For example, I could not view my engine’s temperature with it on my 2005 Nissan Patrol but I could view it on my 2015 ford raptor. It is not specifically mentioned on its manual/website what info it will support to display, I guess it may vary depending on the specific car make variant & model. 

However the older your vehicle is, the greater the chance that it will not support your car.

The price of VJOYCAR V70 is no different than the KONNWER KW206

Functions

  • Full OBD-II read & clear functionality
  • Knockoff version of KONNWER KW206
  • Temperature/Voltage alarm if it exceeds unwanted level. (can be adjusted)

Compatibility

VJOYCAR V70 supports American vehicles newer than 2003, same goes for Asian, European & Russian/Chinese market.

5. Wiiyii HUD P6

The Wiiyii is a knock-off version of the Lufi XF, I’ve used this tool for approximately 2 weeks & I’ve gotta say, I’ve got no complaints, especially considering the fact that it costs only half the price of the original tool.

it’s worth noting that integrating brand names like Renault, Peugeot, Citroen, Fiat, DS, Lamborghini, Jeep, SIMCA, and Suzuki might present compatibility challenges due to mechanical disparities or brand-specific design philosophies.

It is worth noting that this tool often shuts down on its own after a while the car is left idle or is moving at a constant speed on cruise control.

The build quality of it is also quite unimpressive, It almost feels like it will break in half in case it falls on the ground. 

Pros

  • Highly affordable.
  • Great Compatibility with American car brands. (2003 and older)
  • Highly customizable.
  • Accurate readings.
  • Includes a built-in OBD2 scanner.

Cons

  • Looks a bit ugly.
  • Does not support Oil pressure/temperature.
  • Cheap build quality.
  • Awful customer support.

Compatibility

Wiiyii HUD does not offer great compatibility with older vehicles, It would not display water coolant temperature & also sometimes display incorrect RPM on my 2005 ford truck.

Wiiyii does not have their contact email or number you could contact, they also do not have an official website where you could download the updates.

Data Visualization

Data Visualization options are very similar to Lufi XF.

Real-Time Monitoring

For me, the most useful data types were:

  • Water Coolant Temp
  • Fuel avg (interchangeable from Km/L to Miles/Gallon and vice versa)
  • Avg Speed
  • RPM
  • Trip mileage
  • Battery voltage

Connectivity

Wiiyii HUD P6 can only be connected to the OBD2 port of your vehicle with the cord that comes along with it in the box.

Additional Features

FAQs

What is an OBD2 gauge display, and how does it work? 

An OBD2 gauge display is like your car’s personal health monitor. It plugs into your vehicle’s OBD2 (On-Board Diagnostics) port, typically located near the driver’s seat, and acts as a window into your car’s inner workings. It’s your digital co-pilot, showing real-time data like engine RPM, speed, coolant temperature, and more, all on a handy screen. It works by tapping into your car’s onboard computer system and decoding the data it generates.
