Audi RS7 C7 4.0TFSI is equipped with an 8-speed ZF AL551 transmission. Its mechanical strength and build quality mean that it can handle power up to 1000 hp / 1000 Nm without problems.
However, there is a torque limit in the transmission software, set at 700 Nm. The software also causes significant delay in gear shifts, making them pleasant for passengers but slow for operation.
Almost no one in the world offers software for this transmission, the company Etuners has developed a software solution that will improve dynamic performance as well as the usability of the automatic transmission.
Etuners software for the 8-speed ZF AL551 transmission includes:
1. Removal of torque limiters, allowing it to raise up to 1000 Nm.
2. Reduced shift time, so the shift time is more like DSG rather than an automatic transmission.
3. Individual shift points to improve acceleration.
Software is also available for the following Audi models:
Audi S8
Audi Q5
Audi SQ5
Audi RS6
