Diablosport Trinity T2 Review

Diablosport Trinity T2 Tuner

I received my Diablosport Trinity T2 tuner in the mail a few days ago. I have to admit I was blown away by the quality of the unit, but the thing that got me first was how well it was packaged. Inside my FedEx box was the T2 box, completely sealed in plastic. Peeling the plastic off allows you to remove a heavily embossed slipcover which finally allows you to open the T2 box and reveal the unit. Inside the box you’ll find a quick start guide, owners manual, several very high quality Diablosport appliques, the Trinity T2 itself, USB cable, windshield mount and OBD-II cable.


One of the first things I noticed about the OBD-II cable (that I had apparently missed in my initial readings on it) is that it uses an HDMI port. Don’t get me wrong, I’m stoked that I won’t have to deal with the sometimes-difficult duplex connector from the old trinity, but this is the only time I’ve seen a HDMI connection used for something other than A/V.  Secondary to that weirdness though are two really cool features. One is the additional length of the cable. I didn’t measure everything up, but I’d estimate the cable at a solid 1.5 to 2 feet longer than the old trinity cable. Number two is the accessory port. Diablosport claims this allows you to connect aftermarket sensors such as EGT or wideband directly into the Trinity unit.


Once I got the T2 out and hooked into my computer with the included USB cable, the problems started! My computer recognized the T2 was connected, but DSDL did not! Reading over the Diablosport downloads page didn’t indicate that anything else would work with the unit, so I searched their forum.  Turns out the new Diablosport Trinity T2 uses the ‘Ignition’ software originally developed for the inTune tuners. Once I got that installed, it immediately detected the T2, connected to it, and notified me of available updates.


After the updates completed, I did a second check, and then took it out to the fun-mobile. It’s much quicker to boot than the old T-1000, although I would still be okay with it moving even faster. After playing around with it I realized there are A LOT of options for data monitoring and logging. Speaking of logging, data is easily logged to internal storage with the simple press of a touch screen to start the process. The button to start it is displayed right on the gauge display, and starts the moment the ‘button’ is pressed. The layout (and therefore the data recorded) is very easily customized with a quick-access swipe down menu from the top giving you your options.

One quick note regarding datalogging.

For reasons unknown it had a problem saving my log which resulted in the screen staying on awaiting my input which drained my lightweight Braille battery over the course of the next 2 days. Had I a 50lb stock battery, it probably would have been okay, but just something to watch for.


All done data logging and ready to tune? You’ve still got the full suite of quick-adjust options as well as the full-on custom PCM tune option. Additionally you can store multiple custom tunes on the tuner now (although I have not tested this) for quick switching between ‘track-ready’ ‘street friendly’ and maybe something gross like, eco-mode? It also means you can quickly switch back to a known-good tune in addition to just the stock tune as on the previous Trinity. To make it even faster the T2 is also WiFi-capable!

The really amazing thing to notice on this device though is the screen. All in all, the other components are mostly just enhancements of previously good design; however, the touchscreen is a glory to behold. If you want to impress your friends and family with your awesome build, plant the trinity right in the middle of it. The resolution is incredibly crisp and the touch screen is magnificently responsive. I absolutely do not regret having sold my old T-1000 to switch to the Diablosport Trinity T2.

If you are in the market for a tuner I strongly recommend Diablosport. If you’re in the market for the best tuner you can buy, then you need a Diablosport Trinity T2 EX in your hands.
