The Zilla iPhone app won’t give your car 485 horsepower, it won’t boost your torque to 434 ft lb and it won’t give you AWD. What it will do is give you telemetry data similar to what’s available from Nissan’s supercar, which can help in tuning your own ride or in improving your lap times. For a mere $2.99, less than a single gallon of gas, Zilla (short for “Godzilla”, the GT-R’s nickname) gives you all the performance data you could possibly want. You get G meters for acceleration and braking, lateral acceleration, current speed display. a G vector plot, a compass bearing, average speed, a weight transfer graphic and an integrated iPod controller. It’s not going to give you F1 quality data, but it’s more accurate than the butt dyno and it’ a whole lot less money than having a professional-grade system built, installed and calibrated. Video below.
The Zilla app works in either portrait or landscape orientation and allows a high level of user customization to display only the data you want to see. The designers built the app to be driver friendly, with features such as large readouts and one tap calibration. Like other G-meter apps, I suspect that accuracy is mount and orientation dependent, so the best results will come from a rigid vehicle mount that keeps your iPhone perfectly vertical or perfectly horizontal. It’s only available for the iPhone, so Android users are out of luck for the time being.
