In last month’s issue we dyno tuned our late model Hemi project car, the Maulin’ Magnum. The custom tune was accomplished on a Dynapack variable load dynamometer in concert with a Diablosport Predator hand held tuner. We then tested the tune on the track and the street and were pleased with the result.

Well, Diablosport has a new weapon of computer control in their arsenal, the Trinity. The Trinity does everything the Predator does and a whole lot more. It comes loaded with Diablosport performance tunes, just like the Predator. But, it is also functions as a virtual gauge display capable of reading and displaying up to five parameters at a time. It is also able to monitor and data log dozens of “gauges” whether displayed or not. It can function as a shift light, and includes a drag strip Christmas tree simulator.

Diablosport sent us a Trinity to install and test on the Maulin’ Magnum. We have some very interesting things in store for our 2007 Dodge Magnum SRT8 (stay tuned to these pages for some great tech articles in the coming months), and several of them will require more dyno tuning. Since we also bracket race the Magnum in three different racing series, we hope to appreciate the additional capabilities of the Trinity over our old trusty Predator.

The box comes with the Trinity and includes cables to hook it up to the OBD II port of your car; a USB cable to attach it to your computer (for downloading tuning updates); a CD with software, manuals, and three very useful video tutorials; and a suction based windshield mount.

Since we had a custom tune in our car and the Predator, we made contact with Diablosport technical support to get assistance in transferring the tune to the Trinity. With that accomplished, we followed the directions in the video tutorials to update the unit and install the tune into our car. With that, we were ready to play, twenty-first century style.

Back in the day, when most cars had carburetors, if you had a street/strip car you also had a carb and ignition tuning toolbox. Various sized jets, spare needle valves, fuel bowl gaskets, as well as spare condensers, points, advance weights and springs for your distributor—these were as indispensible as fuel. Late model Hemis don’t need that stuff, now it’s all about tuning your engine control computer. And the Trinity seems to give us a lot of information and control.
