Since it’s launch in January 2014, ProECU for Nissan GT-R Phase 4 has supported all MY2014 Euro/JDM/Rest of the World and MY2015 US models. A significant achievement, supporting a new model with our full feature set so soon after release. And that feature set includes, RaceROM Boost Controller, Adjustable Launch RPM, Boost Off The Line, Map Switching and the simply amazing RaceROM Rolling Launch. All this is protected by our unique Custom Map feature which can provide failsafe protections for any situation. Ben tuned Mike’s MY2015 GT-R remotely in Las Vegas with full bolt ons and using the Flex Fuel capability of our Phase 4 release. Picking up a full 100whp increase over stock.
