Autotuner Update!
The Autotuner team unveil a new technological breakthrough for AT Tool and AT One: the introduction of an exclusive protocol specifically designed for Audi e-tron / e-tron GT and Porsche Taycan (1st gen).
This protocol now enables full read/write access to Continental ASG1 ECUs directly via OBD. These control units, previously heavily restricted, manage engines that are significantly limited electronically, making them extremely receptive to performance gains.
Crucially, all performance enhancements remain safeguarded by the vehicle’s Battery Management System (BMS), which continuously monitors and ensures that power output never exceeds what the battery can safely deliver.
In short: they can finally unlock these powertrains and let them perform at the level their precision-engineered chassis deserves, while keeping everything fully protected by the BMS.
