BMW S55 M3/4 M2C Custom Tune
With ProTuningFreaks latest customROM development new DME Logic has been added which gives us features as:

Driver is able to switch between 4 individual tunes on the fly from the steering wheel. MAP 1 can be Maxed out tune on E-Mix Map 2 Medium Power or Track tune on 93aki/98 Map 3 Low boost and Map 4 Valet mode. Each individual map slot can be adjusted to the users needs.

Flex Fuel
Flex Fuel logic allows us to to create a custom calibration which will adjust boost, AFR, ignition angle dynamically based on the ethanol content sensor input. To run this feature you will need to install Flex Fuel kit from protuningfreaks website which can be purchased here.

Anti-Lag is the great feature that will eliminate the turbo lag while roll racing or drag racing with the vehicle standing still, making the car leave the start line or launch from the roll without losing any milliseconds off of a your 1/4mile, 60-130mph or 100-200kmh times. This feature is fully customizable within the tune to adjust it for the fuel being used and the turbocharger size. This feature has safety thresholds to deactivate it based on the engine oil temp EGT (exhaust gas temperature) and the total duration time can be set for how much time it can be active.

A good anti-lag adjustment will help the car grip well as well as shed off couple hundreds of milliseconds from your time slips.
