Whats a good Ecu for a s5 T2 for daily driving?

 

The ECU that your local tuner likes, knows how to install and tune, and recommends for your particular application.

 

im with evil on this one. youll need the one that your tuner can tune the best. i personally suggest rtek 1.7 so you dont have to tune it as much. the down side is you have to send your stock ECU off to get it installed
