## Questions & Answers

**Q: can the bottom graph be programmed to show rpm?**
A: Yes, but the range cannot be set. The shift rpm setting will modify the red point of the graph though.

**Q: Does this work on 2003 Jeep liberty?**
A: It should work with any obd2 plug in.  Follow the instructions to your preferences.

**Q: can the alarm temperature level be adjusted? I would like the high temperature alarm to sound at a lower temperature than the normal warning light**
A: Yes, You can adjust in setting

**Q: Once the unit is programmed will the unit automatically show, for example, MPH or must you reprogram every time you start the car?**
A: Once programmed it retains the settings.  It must have non-volatile memory because it retained the settings even when I unplugged the OBDC connection.  Note this is the Plus version.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Compact OBDII Can Display in MPH, Fahrenheit, & MPG in top display area
*by C***H on April 30, 2018*

The Autool x50 PLUS works perfectly with my 2008 Honda Pilot (OBD Type ISO 9141-2).It was delivered fast and looks great and is very simple to hook up, just one connection. The display has an auto turn on, it turns on when you start the car and an auto shutoff, shutoff time is adjustable up to 20 minutes after the car is turned off. The display is easy to see, day and night. The brightness level, is controlled by a light sensor and it is not manually adjustable. I have mine is setting in front of my instrument panel and the display brightness is just fine day or night. After installing the Autool x50 PLUS, I had some question, So, I emailed the seller “OBDIIShop” and they replied as quickly as hour later a couple of times, BUT, never longer than 24 hours, they appear to be closed on the weekends. The reply emails were very helpful in answering all my questions. Their customer service is great!The Autool x50 PLUS has Lots of customization options. The X50 PLUS has four area’s/positions on the main display. The Position 1 (Largest read out) can display MPH / Km/H speeds, coolant temperature in F or C, Fuel in MPG or LPH and many other read outs are available by just by toggling the switch below the display to the left or right. Position 2 and 3 (Smaller readouts in center left and right of display) can be configured to show multiple different measurements (Position 2 and 3 only display metric units NOT US/imperial units), I did not find this an issue because, I have mine set for Voltage and Engine RPM, Position 4 only can configure instantaneous fuel consumption or engine rotation progress bar display.I used mine mainly for Speed with the Speed Alarm on the Position 1 and MPG, (to prevent a heavy foot during acceleration) on the progress bar display. Both the large/primary and the progress bar display can easily be seen with a quick glance. The MPH speed alarm setting can be set in the Menu “Settings” under OverSpeedSet”. The easiest way to set it, is to convert the MPH you want the alarm sound at (use the internet for conversion), to Km/H and enter that speed into the ”OverSpeedSet”. The nicest thing about the speed alarm is the speed readout changes from white to red when you go over the speed alarm limit. If you don’t want the alarm to turn on just set it to 160 that is 99.41MPH, or use a higher number if you drive fastest than this.AVG and Current MPG are accurate, BUT you will need to go into the setting menu and make sure your “Engine Size” is correct and the “KPH” is set show your correct vehicle speed in MPH or Km/H which ever one you use while driving. After that you need to go through a few gas full ups and manually figure you gas mileage and then adjust the “Fuel Adjust %” in the menu settings, the more you do this, the AVG and Current MPG / Km/H Display will be more accurate. You have to do this even with “SCAN GAUGE”. I also have a SCAN GAUGE, but for information at a quick glance, the Autool X50 PLUS can’t be beat.“OBD Diagnose” lets you read and reset OBD scan codes, also you can read the real time active data that is available to your OBDII port, just go to Menu, “OBD Diagnose”, “DATA Stream”. It is great way to see why your Check Engine light is on.There are a lot of features in the Autool x50 Plus and I haven’t used them all, like the “Driving Test” Menu that check braking time and distance and Speed test.

### ⭐ Faulty, slow, and defective
*by V***T on July 2, 2024*

I had hopes for this one and picked it up to be able to gauge my fuel economy on an older 2005 Nissan Pathfinder. Upon plugging it in, it caused all my gauges to go out of wack and lit a service light that wasn't there before and two more warning lights: disabling my Vehicle Dynamic Control (VDC) and activating a slip light. This is a traction control system, I believe, and maybe it's just a warning light but the system nevertheless claimed it was disabled. All this from plugging this device in. It's easy to plug in and get working but, if I'm being honest, it's not practical. It takes nearly 1-2 minutes for it to actually read the computer and activate making it a nuisance really. Sending this one back as it failed to deliver. Maybe it's good for limited use but definitely not on a day-to-day, and not for my application.

### ⭐⭐⭐⭐⭐ Water Temp Gauge
*by J***K on July 7, 2023*

The product easily connects to your OBD two port under your dash. It has lasted for over a year with no problems. My Scion does not have a water temperature gauge and I needed one for the hot Arizona weather I am in. You can mount it wherever you want because it has a 3-4 foot cord and I can easily see the numbers while I am driving. It also can cycle through other functions like a tachometer, a voltmeter, and other functions. But I primarily got it for the water temperature gauge. Well worth the money.
