    • Custom Code/Iroz Motorsport release 8V RS3 Sedan and 8S TT-RS 2.5 TFSI dual clutch TCU tuning software

      TCU (transmission control unit) tuning is increasingly important with modern cars in order to get the transmission to play nicely with upgrades. The Audi RS3 sedan and TT-RS obviously share a dual clutch transmission and with the 2.5 TFSI motor putting out a ton of torque in the aftermarket TCU tunes will be necessary.


      Especially when the time comes for upgraded clutch discs.

      As for right now, Custom Code and Iroz Motorsport are claiming improved shift times, raised rpm shift points, improved launch control, and higher line pressure for greater torque capacity.

      Hopefully we get some third party feedback verifying the claims.

        According to a video that george@malaka made he is seeing some slippage however to be fair he's probably approaching 700whp which is about 2X what the stock car care with...

        Adding this TCU software to a stock turbo car is a must

        Adding this TCU software AND upgraded clutches to an upgraded turbo car is a must, eventually.
