MyVoltControl vs evDash OBD2

MyVoltControl is designed specifically for the Chevrolet Volt (and related models), and the Chevrolet Bolt. ("Related models" include the Cadillac ELR, Cadillac CT6, Opel Ampera, Holden Volt, Opel Ampera-e.) MyVoltControl requires the use of an OBD adapter that complies with the ELM327 specification (most do). You can use either: - an OBDLink MX+ OBD adapter (preferred) - an OBDLink MX-WiFi OBD adapter - a Bluetooth-Low-Energy (aka Bluetooth 4) OBD adapter. (Classic bluetooth adapters are not supported by iOS.) - a generic WiFi OBD adapter will work in most cases (but is not recommended). If you need to buy an adapter, or to see a list of some that aren't ELM327 compatible, refer to the information in our FAQ page at http://www.CraftinDeApps.com/FAQ#MVC These adapters plug into the OBD-II port under the left side of your dash. The App itself is free. Use of the functions described below requires one-time in-app purchases to enable each one that you want to use. MyVoltControl consolidates four functions, long available for other phones, and makes them available for the iPhone and iPad. In addition, the last one is unique to this app. These are known as: -->> MyVoltHold -->> MyVoltLifetime -->> MyVoltDiag -->> MyVoltAfterblow -->> MyVolt12v -->> The Volt Hold function does four things. - First, at the top, it has several "information pages" that you can switch between to see information about your car. These are shown in the photos above. - Second, it allows you to turn on a "Hold" mode which approximates the Hold mode built into the car beginning with the 2013 model. This Hold mode turns on the internal combustion engine (ICE) as needed to try to maintain a State of Charge value that is close to the charge that was present when you turned the mode on. So why, you may ask, would I want that function on a newer car. Very simple really. Since Sport mode and Hold mode are mutually exclusive, this function allows you to use the car Mode button to engage Sport mode, while using the Hold function in this App to achieve Hold mode at the same time! Hold mode can also be automatically engaged based on several factors. - Next, it allows you to ask the car to run the internal combustion engine. You can use this to get heat from the engine on a cold morning, or to manually simulate your own Hold mode if you prefer. - Finally, you can also use this function to force the ICE off, which you might want to do if the ICE is running due to low temperature (done for driver comfort). The Volt Hold function is not available (and would serve no purpose) on the Chevrolet Bolt models. -->> The Volt Lifetime function allows you to reset the lifetime fuel economy value ("Lifetime MPG" or "Lifetime L/100km") value for your car. You will find this useful if you've purchased a car which has recorded the previous owner's fuel economy results. You can also use this to calculate the distance travelled in both EV mode and on the ICE by entering the Lifetime Economy number shown on your dash. The Volt Lifetime function is not available (and would serve no purpose) on the Chevrolet Bolt models. -->> The Volt Diag function allows you to run some tests on your high-voltage (traction) battery. -->> The Volt Afterblow function allows you to control a system that GM added to your car to dry out the A/C vents. This system is OFF by default and the Volt Afterblow function allows you to turn it on (or back off). This app function is not available for 2013 model year cars. - You can use the Volt Afterblow feature ONLY if you are using an OBD adapter which supports the SWCAN (aka GMLAN) bus. It must also support the "ST" command set (in addition to the common "AT" command set). Very few adapters offer this support. The known to be good and recommended adapters for this are the OBDLink MX+ or the OBDLink MX-Wifi adapters. -->> The Volt 12v function displays graphs showing the values of voltage and current on your 12 volt battery.

evDash OBD2 is a live dashboard and diagnostics multitool for electric vehicles. Connect a compatible OBD2 adapter and view real-time EV data on your phone or Apple CarPlay. evDash is built to support as many electric cars as possible — if a vehicle exposes useful data over OBD2, the goal is to make it work. Main features: • Live EV dashboard with battery, power and driving data • Battery SOC, SOH, voltage, current and charging overview • Cell voltages, temperature data and 12V battery status • Charging graphs and trip energy statistics • Apple CarPlay support • Multi-car garage with quick switching • Service Menu with ECU scan, ECU versions and DTC tools • Pre-purchase battery check and battery health tests • Acceleration and brake tests • TPMS, CAN sniffer and diagnostic export tools • Remote Tuning to help add or improve vehicle support • Local logs, exports and optional remote upload evDash works with supported OBD2 BLE, BT3/SPP, WiFi, MFi/OBDLink, BMW ENET and evDash M5Stack relay adapters. Available data depends on the vehicle model, adapter type and supported vehicle profile. Some cars expose a lot of battery data, some expose only basic OBD2 data, and some are restricted by the vehicle gateway. Which cars are supported, and which data each one provides, is listed in the vehicle support matrix, updated with every release: https://www.evdash.eu/evdash/vehicles/ Reported anomalies — what owners observed after connecting an adapter or during diagnostics, with investigation status and precautions: https://www.evdash.eu/evdash/vehicles/incidents/ evDash Pro unlocks advanced diagnostics, multi-car quick switch, battery internal resistance calculation, cell health tests, graph exports, Service Menu tools and fullscreen diagnostic views. It is available as a monthly or yearly auto-renewable subscription, or as a one-time lifetime purchase. Monthly and yearly plans include the same Pro features. Pricing is displayed in the App Store before purchase and may vary by region. Payment is charged to your Apple ID account at confirmation of purchase.
