MapEV performance tuning for the Porsche Taycan and Audi E-tron
EFI Motorsport is proud to be the official distributor for the Americas of MapEV, the premier performance tuner for select Audi and Porsche EV vehicles.
First and foremost, the Map EV solution retains the factory warranty. Your original control unit is not modified in any way, and as long as it is re-fitted for dealership visits, the factory warranty will not be affected. MapEV does not offer modification of the original control unit for this reason.
While at the time of writing the factory is not flagging J1 platform vehicles with modified control units, this can change at any moment in the future. Even now the factory knows exactly which cars have been to the dealer with a modified control unit, however they are choosing not to void the warranty at this time.
NB! If any company tells you that modifications to the control unit are undetectable, they either do not understand how the "Tuning Detection" (TD1) process works, or are simply not telling you the truth.
power gains vary model to model, but as an example the Porsche Taycan 4S with performance battery option goes from 489 PS (482 HP) to an astounding 730 PS (720 HP).
Currently all pre facelift (pre 2025 / late model 2024) Porsche Taycan (Turbo, Turbo S, GTS, 4S, 4, and Base) models are supported as well as the pre facelift (again pre 2025 / late model 2024) Audi e-tron (GT and RS) models.
Ordering Process
There are two basic ways we can supply controllers: unlocked without a VIN (destination flash) where the controller will need to be flashed via ENet cable through your OBD port or pre flashed ready to install and drive. At this time we are only offering pre flashed controllers to end users while we build our installer network. For a pre flashed controller you will first need to identify the software version on your car via the MapEV Diag software and an ENet cable via OBD. If you'd like to purchase just an ENet cable they are available on amazon or we also can supply them here. If you purchase a controller without specifying a VIN we will wait until you have identified the car to ship your controller. See below for details.
- Download the MapEV Diag software. You will need a BMW ENET cable and a PC to use it (one can be shipped with your order if desired, select the option at checkout).
- Connect the cable between the vehicle and the PC, turn on the ignition.
- Click the "Scan Vehicle" button.
- Click the "Read ASG Info" button, and agree to upload the data to MapEV.
Installation of the control unit takes about an hour even for a novice. As we build a dealer network we will have recommended retailers and installers across the country. in the mean time here is a video of the installation process by MapEV.
Please specify your VIN at the input above. IF NO VALID VIN IS SUPPLIED WE WILL HOLD YOUR ORDER UNTIL YOU DO SO. FURTHERMORE, WE REQUIRE THE VEHICLE BE IDENTIFIED VIA THE MapEV DIAG SOFTWARE BEFORE WE CAN SHIP A FLASHED CONTROLLER TO YOU.
