    • APR demonstrates 8V Audi RS3 Sedan / TT-RS 2.5 TFSI ECU map switching - 91, 93, 100, 104 octane, E85, or valet modes

      Great news for 2.5 TFSI enthusiasts waiting on APR's upcoming tuning software release. APR will allow you to switch up to four maps using either a mobile app or the stalk on the steering wheel to accommodate various fuels or modes.


      For example, you are pulling your 9-second RS3 into valet and see a 17-year old eager to get his hands on your car. You can quickly change the car into a limited valet ECU mode.

      Furthermore, there are four slots total so what you want to accommodate is up to you. Your choices are 91, 93, 100, and 104 octane gasoline tuning maps. You can also run an E85 map. The choices are up to you.

      This is similar to MRC Tuning's system although APR also has a mobile option for your cell phone. This allows on the fly switching which the cruise stalk will not to prevent accidentally switching to the wrong map.

        i still cant believe they ran 9s on a hybrid though, that's insane in itself
