Leaf Spy Lite

★★★★★ If you are looking to purchase a used Leaf, this program is a must-have. I went to a car auction and examined 14 Leafs. I narrowed it down to three vehicles, all had all 12 battery bars shown on the dash. But with Leaf Spy, I was able to tell which car had more battery capacity remaining. The first bar doesn't disappear until the battery drops below 85%. The car with 90.96% battery had the same amount of bars as the 86.2% one. Since the range reported by the car depends on driving history, it isn't a reliable indication of actual battery capability. It can also tell you how many times the vehicle has been charged using the quick charger and how many times it been charged with the level 1 or level 2 charger. This is important because some maintain that too much quick charging can damage the battery, long term. Leaf Spy Lite only has two screens, but for my comparison shopping, it was enough. My only criticism is they use a lot of acronyms, probably to be able to fit all the info on the screen. SOH is State of Health = battery capacity. QCs is Quick Charge = number of quick charges. L1/L1 is a number of regular charges.

★★★★★ Good diagnostic tool This tool is really only ment to help configure the blue tooth obd2 adapter with your android device, only basic info available in the lite version, like SOC or state of charge, which is the measure of remaining battery power, GID, which can be used to calculate wattage (GID * .08 = kilowatts currently stored) battery temps and a graph of individual battery packs and how balanced in terms of voltage they are.

★★★★★ This works with a Samsung S21 and a Konnwei KW902 OBDII adapter. You need to be VERY CAREFUL to get a compatible OBDII adapter - the cheap ones don't work, get a KW902. Also, the Bluetooth link has problems with Apple phones, or so I hear. Get the Bluetooth paired before starting the app, and then select the adapter through the config menu, and it should work. The info is all there, but for the real stuff you need the Pro version which costs.

★★☆☆☆ Not sure why, but it's not connecting to the dongle. Does only the Konnwei KW902 works with the app?. What abou the OBD Link MX or EX? Thanks

★★☆☆☆ I can't get any Wi-Fi devices to come up, is the app faulty???

★★☆☆☆ Not a good advert It needs to have more features and be easier to use if you want us to consider the pro version

★★☆☆☆ Can't connect Samsung Galaxy 7 to Konnwei KE902. Keeps saying "socket closed". 2013 Leaf SL. Useless app and dongle. Do not buy.
