The Diablo Trinity is one of the most advanced devices of its kind on the market featuring: color touch screen, advanced data acquisitions, customizable gauges, dyno-tested performance tuning, and full virtual drag tree performance measurements. All this included for one price and housed in a slim, custom styled, easy to use unit.

1. Virtual Gauge Monitor

The Trinity is one of the most advanced diagnostic tuning devices on the market today. With over 100MB of on board memory devoted solely to recording and playing back diagnostic PID/DMR data, it allows users to record hours and hours of continuous data streams directly from the vehicle’s PCM/ECM.
The Trinity interprets PID and DMR data received from the OBD-II Diagnostic port on your vehicle and converts it into a readable format: A Virtual Gauge! Individual user customization is one of Trinity's most recgonizable features.

With Trinity's dynamic gauge layout there is literally an infinite number of combinations/customization of gauges to view!

2. Virtual Drag Tree

We just discussed the Trinity’s virtual gauge system and how your vehicle’s sensors can be displayed on the screen in real time- but did you know that there is information coming from your vehicle that can allow the Trinity to approximate all kinds of interesting read outs? One of the most intriguing is the Virtual Drag Tree! Using parameters such as vehicle speed, peak torque, wheel speed and others, the Trinity is able to give you an estimated 0-60 MPH, quarter mile, 1/8 mile or time trial. Keep in mind that these numbers may or may not be accurate depending on variables such as traction and road conditions, but they sure are fun to see!

The Trinity’s virtual tree allows users to choose to either monitor their reaction time (like the real world) or have the tree start when they press the gas from a stop. There are advantages to both! If you are using reaction time, you will gain experience for the track when launching off the line while the motion start will show you the time less human error. It’s your choice as to which you prefer!

3. Performance Programmer

The Trinity’s tuning options vary depending on the vehicle that is being tuned. Gasoline powered vehicles feature tunes based on minimum octane ratings while diesel tuning is based on Horse Power Ratings. By way of example, If you have a 2008 Chrysler 300C your options in the tuning menu might be: 93 Octane Performance tune, 91 Octane Performance Tune, and a 2007 F-350 with a 6.0L PowerStroke might have the options of stock, 40 HP, 65 HP, and 100 HP. (Note:These options may not be the same in all models and can vary based on the current update of the tool).


Diesel Tuning
Diesel trucks have massive horsepower and torque potential that can be unlocked just by programming the vehicle’s PCM or Powertrain Contol Module. Your application may have tunes for any of the following, plus more!

Towing: This setting is generally a of 40-60 HP and an average of 100 Ft/Lbs of torque (depending on application) and is for use when towing heavy loads up to the factory towing capacity. This setting is designed to increase drivability while towing, net extra economy when cruising at highway speeds, and is helpful when driving through mountains while towing. Fuel economy improvement is not guaranteed and will depend on factors besides the tuning including driving conditions, driving habits, and load.

Economy: adds between 60-100 HP and 180-200 Ft/Lbs of Torque, economy gains average in the 2-3 MPG range(Highway)! This setting is not designed for heavy towing- limits are in the range of 6,000-8,000 pounds depending on your vehicle’s stock towing capacity. DiabloSport recommends the use of an aftermarket cold air intake and exhaust (4 inch diameter at the down pipe) to further increase fuel economy and reduce exhaust gas temperatures. Fuel economy improvement is not guaranteed and will depend on factors besides the tuning including driving conditions, driving habits, and load.

Extreme: This tune adds anywhere from 100- 185 horsepower and 220+ Ft/Lbs of torque and is specifically for peeling out down the strip! DiabloSport recommends only using the extreme tuning consistently if you have an exhaust and cold air intake due to a possible increase in exhaust gas temperatures.

Gas Tuning
DiabloSport performance tuning with 93 octane can yield anywhere between 15-40 horsepower (measured at the wheels) and about the same in ft/lbs of torque (Some applications gain more or less, depending on engine size and vehicle platform). If you have a gasoline powered vehicle make sure that you are using the minimum octane fuel for the tune you selected. For instance if you are using the 93 Octane Performance Tune, you must run 93 octane in order to avoid spark knock or engine damage. Some areas of the US and abroad may not have access to different octane rated fuels, but if you happen to be somewhere where 93 octane is not available, have no fear- the Trinity allows users to modify their spark and fuel tables so you can run lower octanes. If you are not sure about fuel injection tuning, or how much spark/fuel should be added/removed from your vehicle to run lower octane, ask the question on our forums at, or give DiabloSport tech support a call.
International customers: The settings for the Trinity and the Predator use the North American fuel rating standard. This fuel octane rating standard is more conservative than the other rating system used abroad. For example, 91 octane fuel using the North American standard is equivalent to 95 octane overseas. The 93 octane fuel rating of North America is equivalent to 98 octane fuel overseas. The fuel will perform equally but the rating system is different.

4. Diagnostic Code Reader

Trinity can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year reading/clearing your own computer codes rather than paying a dealer to do the same. It's as easy as a few simple steps.

Step 1: From the main menu of the Trinity select “Diagnostics” Select “Show Trouble Codes” to show the last trouble codes your vehicles PCM displayed.

Step 2: Press the desired trouble code to see a full text description of that code.

Step 3: Once you have seen the trouble codes listed in your vehicles computer, you will eventually want to clear them. In order to do this, press the back button on the right hand side of your Trinity’s screen and select “Clear Trouble Codes” from the trouble codes menu. The Trinity will then display that the faults have been cleared! Press continue…

Step 4: You have now cleared all trouble codes from your vehicles computer!

5. Control your analog devices from the Trinity

The Trinity can also be used to support other DiabloSport products such as the DiabloSport Extreme PowerPuck and/or other third party analog devices such as wideband and EGT. The Trinity has the capability to support two additional analog products at any time. This means you can use the Trinity to adjust your Extreme PowerPuck settings on the fly while monitoring your vehicle's Exhaust Gas Temperatures.
