In the workshop this week our first stage 2 upgrade on the newer Audi S4 B9 turbo. This vehicle has a Wagner up-rated inter-cooler Milltek de-cat exhaust section and high flow carbon intake system.
Audi B9 S4 Tuning on the dyno..
Bench flashing ECU..
Ecu remapping at the moment is a bench flash but no opening of the ECU just a set of cables to enable us to read and write to the ECU.
Tuning was taken care of by one of our tuning partners Avon Tuning and after rolling road testing and optimisation a respectable 430 bhp was achieved on our version 1 stage 2 software transforming the drive of the car with the sort of performance you would expect . We expect more development in time and further improvements to be made . We are also able to offer a stage 1 tune with no hardware modifications.
