Nissan GTR | Ecutek Phase 5 vs COBB V3 | R35 Launch Control

In this video I explain why I went from a Cobb Accessport V3 tune to an Ecutek Phase 5 Tune. I also discuss the Ecutek features. Launch control rpm adjustment, rolling anti lag, ethenol content, transmission shift points and the 4 Maps. Fast forward to 4:50 for the features of Ecutek.
