Ensure the device is not connected to the car’s Apple car play. |
Preparing your vehicle
The car can draw up to 30 Amps amps during the flash, so we recommend using a power supply able to deliver capable of at least 30 Amp amps @ 13,.8V . (e.g. Maas SPS-30).
The voltage power supply needs to must be connected to the terminals in the engine baycompartment. DO NOT connect directly at the vehicle’s battery. to the vehicle battery.
A normal battery-tender or charger does will not help to stabilize stabilise the voltage during the process.
It can only help to pre-charge the battery in advance.
