The Custom ECU software for the McLaren 570s turns this “sport” level McLaren into a true monster with a jekyll and hyde personality. With the stage 1 software the car maintains its nice and linear drivability while cruising around town, however the second you step on the gas you unleash the monster and truly experience the 138 Ft-lbs of torque and 58 horsepower to the wheel gain over the OEM software and that is just the start. Check out the dyno plot for this software and other great products we have for the 570s here.
