Description
Increase Power and Performance. Further enhance the performance of your 2017-2018 4.3L GMC Sierra 1500 with a Trinity 2 Platinum Tuner. The Trinity 2 Platinum Tuner supports third party custom tune files and also comes preloaded with Diablosport's very own pre-configured tune files. When your Sierra rolled off the assembly line, GMC programmed it to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search of more power. So, if your Sierra is bone stock or if you have added a cold air intake, throttle body or exhaust mods, you should invest in a Diablosport Trinity 2 Platinum Tuner to see the full power potential your GMC can make.
User Adjustable. DiabloSport designed its Tuner to be user adjustable. This means you can make further changes to the tune files to suit your particular performance needs. Please note that not all adjustments listed below are available on all vehicles.
Performance Testing. Another really cool feature of the Trinity 2 Tuner is that it allows you to measure your 0-60 time, 0-100 time, 1⁄8 mile elapsed time, and 1⁄4 mile elapsed time, all with just a push of a button. By keeping track of your 0-60 and 1/4 mile times you can see the difference your latest go fast mods have made.
Built-in WiFi. The Diablosport Trinity 2 Tuner is WiFi-capable meaning you will no longer have to plug it into your Mac, Windows or Linux computer to receive the latest Diablosport firmware updates, but that is still an option. Once setup with your Wi-Fi password, the Trinity 2 will download the latest firmware updates via the internet.
Data Logging and Monitoring. With a full color, high-resolution touch screen display, the Diablosport Trinity 2 Tuner makes it easy to read the Built-In Data Logging and/or the Real Time Data, so you can view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.
Diagnostics Tool. The Trinity 2 Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.
Easy to Load; Easy to Restore. When you load your DiabloSport tune on your Sierra, the tuner automatically stores your vehicle's factory settings. To return to the original factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work.
Application. This Diablosport Trinity 2 Platinum Tuner is specifically designed for 2017-2018 GMC Sierra 1500 models equipped with the naturally aspirated 4.3L engine. This Tuner supports custom tune files which are available separately.
