ECRI Wireless Vehicle Calibration Device

great product easy set up took 10 minutes maybe.

Did what I needed it to do

Great Product and easy to use App!

Worked perfect. Customer service was great

The ECRI unit did exactly as advertised for my speedometer needs. The directions and video were helpful and easy to follow as I recalibrated by Jeep Gladiator for new 37” tires. I also took advantage of a couple of other featured setting controls that weren’t important to me when ordering the unit (such allowing my fog lights to stay on with high beams), but have been an added bonus since making the adjustment.

Once I figured out the instructions, it worked beautifully.
Additionally, it looks like it could be used on more than a single vehicle as you must putshase an unlock for a specific VIN

Works as advertised, and is easy to use.

Fixed the speedo and rev limits which is what I bought it for, the other features are all a bonus.

It was very easy to use and did my first Jeep just fine. Then I went to do my second Jeep and they wanted $49 more!! so be aware that you can only do one vehicle at a time and there’s nothing mentioned that it costs more for other vehicles.

great product. 6 stars customer service!

I bought the ECRI to go from factory to 35” tires. The product looks clean and everything in one package. It did calibrate the speedometer but was not easy to get exactly right.
The install is easy but the OBD2 adapter is angled. It was not intuitive for me to plug into the OBD2 connector.
The IOS software loaded fine and seemed to work ok but I had issues a couple of times. Once I got the calibration exact I was done and didn’t want to continue with future use.
I never got the GPS calibration mode to work exactly. It was always one MPH slow.
I tried many times to just go back to factory settings but every time I scrolled to the bottom to the initial settings the screen on the app would refresh.
Once I thought I had finally got the GPS calibration to work correctly so I turned the jeep off and removed the adapters. I drove the jeep at 60 and it was spot on. 10-15 minutes later I decided to take the Jeep out and appreciate my work only to find that the speedometer and GPS had a 2 mph difference. I found that unplugging the 12v usb power adapter with everything else off and using the measure to the center of the wheel 2 worked. Finally 60 on the speedometer was 60 on the gps. Bonus the cruise also was set at 60.
There are a couple of features that it doesn’t have that it should. It does not have an auto start/stop delete. (I contacted the manufacturer who said it may be an option later this year.) There were YouTube videos that showed a setting that would remove the factory 1-3 MPH flexibility to allow for tire wear. This may have helped me in the calibration of the speedometer.
In fairness I didn’t contact the manufacturer to help troubleshoot which is the stubbornness in me to figure it out.

Works exactly as advertised, very user friendly and easy to use.

Works very well, super easy to use and it’s not limited to only one vehicle.

Put 35 inch tires in place of the factory 33s. Speedo was off 4 mph at 60. SGW was very hard to access. Once the bypass was installed the recalibration was done. First attempt using the measurement from the floor to center of hub made the speedo 2 mph to high. Did a calculation and plugged in new number and it is correct. Made a big difference in the way the Jeep shifts and performs. I think there should be a mention that when doing the last steps of the calibration that the Key fob needs to be away from the vehicle to allow all systems to power down. Did find that in the frequent question section. Overall very satisfied.

This was the easiest calibration tool to get my speedometer back in proper sync thanks for a great item.

ECRI Wireless Vehicle Calibration Device

Purchased to recalibrate the Speedometer in my 2012 Wrangler. Works great, easy to set up via the Instructions, and a great, inexpensive alternative to other products to recalibrate the Speedometer. Great features such as DRL Setup and TPMS Threshold are nice.

App was a bit glitchy when creating an account, but after inputing the Login info, if it goes to a blank screen, close the App and reopen, should work just fine.

Highly Recommend!

This device works flawlessly. Very simple to make adjustments. Finally, something that does just what the seller says it will.

I finally got rid of my annoying TPMS light and calibrated my speedometer while I was at it. Worked like a charm on my 2013 JKU.

Worked great to adjust tire size to calibrate speedometer. I also have the fog lights on with the high beams
That is another improvement. Easy to use

$100 a crack at the tire shop each time a TPMS fails on my my '15 JK aftermarket wheels. Two minute shut off with the ECRI and now no more idiot light and system chime fault.

I got the ECRI because I upsized my tires. It did that great!! I was also able to turn on day time lights and check for codes

The ECRI works as advertised. No problems.

2008 JK with 33” tires - prior owner didn’t change sensors. TPM was beeping at me every 2 minutes. $100 including the code to disable is more than the sensors would’ve cost but is what it is - no other way to disable. Gadget also adjusts speedo for accuracy. All in all figured it was worth it and very easy to install/use.

Just FYI.. make sure the unlock fully takes and the account is setup before trying. If anything errors, contact support first.

Mine glitched at first. However, at 6pm CST Kevin responded to my support email and fixed it.

After everything was set up properly I was able to set tire size, adjust TPMS, and change my gear ratio. There were many more options, but that’s all I bought it for.

Highly recommend due to the exceptional customer support.

Much better than the dealership, every time I make a modification and need them to program something.

Thanks Kevin!!

This is a great product for those who increased tire size and type. It easily corrected speedometer error and allowed a lower set point for tps light. Thanks so much. Dealer wanted 500 dollars for this!!
