iTSX Custom Tuning - Ring Tune

Project Vapor Trail was pretty well maxed out with its current combination--that is, until we poured some Shell URT Advanced 116-octane fuel in the tank. Combined with a VMP Tuning custom tune delivered by an SCT iTSX, the Shell fuel was good for a substantial gain across the curve, including a 42hp peak gain.

While at VMP, PVT picked up an official VMP Tuning blower tag to let everyone know it's modded to VMP TVS specs.

With the stock tune filed away for safe keeping, you can choose which custom tune you'd like to upload. For us, this was the last step before driving home, so it was time to reinstall the 93-octane tune. However, the Shell tune is readily available should we want to run the good stuff.

Now the file is installed and you're ready to enjoy the performance of your custom tune.

So pick your file and start programming. The file is first transferred from your iOS device to the iTSX; from there it's uploaded to the PCM.

While tuning your 'Stang with an iOS device is cool, an understated benefit of the iTSX is that you can also datalog with it. This makes keeping tabs on your car's vitals easier, which can also facilitate working with your tuner remotely. The datalogging is achieved in gauge mode. On an iPhone you can display one gauge, while an iPad will support multiple gauges.

Another surprising and delightful feature of the iTSX is that it offers the ability to record performance testing, including eighth-mile drag, quarter-mile drag, 0-60 mph, 60-0 mph braking, and more. Of course, you will need a safe place, like a racetrack, to truly be able to take advantage of this feature.

Before that happens, you get a chance to confirm it's the file that you want to upload.

Here's an example of what one of the datalog files look like on the iOS device. Some of the parameters that are available include mass air voltage, air inlet temperature, spark advance, and even air/fuel on the '11-and-up 'Stangs with dual widebands. You can also add analog inputs for data like exhaust gas temps. Even better, you can log these files and email them to your tuner.
