Even vaunted BMW tuners with deep pockets such as Dinan are forced to resort to piggyback tuning due to the difficulty of gaining access to the modern BMW ECU's. Tuners with some of the best software engineers in the business such as COBB Tuning have stated that the encryption level of the F30 3-Series ECU is government security caliber. COBB has been working for some time now to try to get access to the F30 ECU and there is no telling if they will be able to.
That is why this piece of news comes with some reservations as the tuner did not state how they were able to get access the S55 ECU in the F80 M3 and F82 M4. It certainly would be astounding for a crack to come this quickly as the car just hit the market. BimmerBoost is waiting on further details as the tuner makes preparations to make this software available. As soon as we get the concrete proof rest assured BimmerBoost will bring it to you ASAP.
