Here is a really nice 2015 GT-R. We previously took the car to FBO and tuned it on E85 using EcuTek RaceRom. This time the customer came back in to install a flex fuel kit and do a complete flex fuel tune. We used a Zeitronix based flex fuel kit and Ecutek's newest RaceRom software to complete the job. The results are on the chart bellow. This is showing two runs on E80 at 20psi and two runs on E10 at 18psi... all on the same map!
