DiabloSport Trinity Tuner for 2007-2011 Jeep Wrangler JK 3.8L

The DiabloSport Trinity is a performance programmer, virtual gauge monitor, virtual drag tree and a diagnostic code reader all in one easy to use, high-tech Jeep performance tool! The Trinity is one of the most advanced devices of its kind, featuring full re-flash & reprogram capability, advanced data acquisition, and customizable gauges – all displayed and controlled on a color touch screen and housed in a slim, custom-styled, easy to use device. In addition to the extensive tuning support, it’s loaded with other features like the programmable shift lights, gauge display, 5 volt input, and data logging.

Add horsepower and torque to your Jeep car using DiabloSport’s dyno-tested performance tunes! These tunes are pre-loaded into each Trinity unit specifically to increase your power, economy, and drive-ability. The tunes work great whether on a stock vehicle, or even mildly modified (like an exhaust and cold air intake). DiabloSport takes the guess work out tuning, making safe and reliable horsepower on your ride!

DiabloSport always saves a copy of the vehicle’s factory data in its memory in case it needs to be serviced at the dealership at some point in the future. That means you always have a copy of your vehicle data on your tuner and once it’s restored it leaves no footprints or watermarks in the vehicle’s computer, so it’s not detectable!

The Trinity, in addition to its other OBD-II Features, allows users to monitor all of their important factory sensors. This is critical when you’re performing at the highest levels. Trinity’s Monitor mode will monitor sensors like Injector Pulse Width and balance rates, Battery Voltage, Coolant Temp, Trans Temp, Vehicle Load, Water Temp, Intake Air Temp, and many more!

More gauge options include The LED lights on the side of the Trinity that can also be programmed as a shift-light on manual transmissions, or warning lights for the sensors that reach certain values! Gauges come pre-loaded in the tuner, or can be user customized to the preferred gauge style and configuration. Trinity’s gauges have optional backgrounds, hundreds of sensors available to monitor, and they can be recorded for up to 5 hours. When you have a Trinity, you’ll never need to buy another gauge for your Jeep again!
