This tool paid for itself the day it arrived.

This tool paid for itself the day it arrived. I disabled the backup warning (it had to go) and low speed warning noises. The tire pressure monitor (TPM) is very helpful. It took about 15 mins to get the TPM assigned to the correct corner once I understood the GUI. The assigning process could be much more simple, but it does work fine. I like having the live data from the TPMs. Very useful battery monitoring tools that take some time to understand the data your getting. I found some of the change options under the service screen (if used incorrectly) detriment. The warnings are there and would recommend users heed them or at least proceed with carefully.


Great tool for anyone with a Leaf

This is a great tool to get additional info from the Leaf about battery health, battery temp, tire pressure, and more!

This latest version added support for turning off the annoying backup sound as well as the slow forward motion high pitched sounds - allowing the 2013 and later Leafs to be quiet as they should. The moment I got this version I turned off the annoying VSP sounds making the Leaf much better! Thanks for adding this functionality!


Paid for itself!

This app just paid for itself by letting me register the TPMS of my winter tires/wheels instead of paying a tire shop or dealer to do it. That alone is worth the app price, but it also adds all kinds of useful information regarding battery health, etc. only downside is that I wish the UI was a bit easier to use.
