Corvette Diablo Sport Predator Tuner

What is the Diablosport Predator?

The Predator is a state-of-the art corvette accessory, high performance tuning flash programmer in a sleek handheld design. Once connected to your Corvette, the Predators internal computer recognizes the Corvette's PCM and automatically picks the proper tuning files designed specifically for that PCM. Inside the Predator's memory are the actual tuning files that optimize spark timing and air/fuel ratio curves. The transmission parameters are remapped to improve the shift characteristics such as shift firmness and shift points. Unlike other 'tuners', DiabloSport's programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and a more predictable power delivery. DiabloSport engineers spend many hours on the dyno, street and track to ensure the tunes provided with the Predator are the best they can be for your Corvette.

The Predator is the most advanced tuning programmer available today. It has taken the hand-held programmer to a new level. You will notice quicker acceleration and better throttle response. If you have an automatic transmission, the Predator will also give you a firmer, more responsive shift pattern (gas vehicles only at this time). The Predator will raise your rev limiter as well as it allows you to raise your top end speed limiter if you have installed high speed rated tires.

A unique feature of the Predator is that is allows you, the user, to “fine tune” DiabloSports program. Since vehicles are located at different elevations or different weather climates, the way the vehicle responds to the DiabloSport program may vary (not all vehicles are exactly alike). Some vehicles will see better gains than others and some may see better (or worse) gains than advertised. This is due to the fact that not all vehicles respond exactly the same. Now, here’s the good news…If you're not totally satisfied with the way DiabloSport program performs, the Predator allows you to make your own adjustments to the program. For example: If you feel that the shift points are too firm, you can go into the program and lower the transmission line pressure (gas vehicles). If you feel that you can benefit from a higher shift point rpm, you can go into the program and raise shift points. If you feel that you will benefit from a few more degrees of ignition timing, you can go into the program and add some timing (gas vehicles). The Predator allows you to "fine tune" the DiabloSport program to meet your specific requirements.

The Predator has diagnostic abilities near identical to GM’s Tech2 software. The predator will allow you to read diagnostic trouble codes (DTC), erase DTC’s and perform live data monitoring. You can monitor your engine sensors while driving your vehicle and much more.
The Predator will save the original GM program so if at any time you want to go back to the original factory specifications, it will allow you to do so.

Dyno Tested Performance Tunes

The Predator was created for the Corvette with one thing in mind, POWER!

Average power gains are per tune. The Predators additional power makes itself noticeable immediately with an increase in power that starts in the low RPMs and builds into a frenzy at the high RPMs.

A Predator equipped Corvette will notice significant improvements in drivability. The additional power and improved shift patterns created by the Predator tune will yield quicker acceleration and better mileage, whether it is in town or out on the highway.

The power increase in the lower RPMs will yield a better throttle response. The increase in MPG is a byproduct of maximized engine efficiency, the improved timing curve and air/fuel ratio creates a more complete combustion, i.e. the engine extracts more power from each molecule of gasoline.

User adjustability. the user can set their own parameters - Choose from DiabloSport's performance program, have a custom performance program made for you by a Diablo Tuner, or create your own:

a. Richen or lean fuel mixture
b. Advance or retard ignition timing
c. Raise and lower shift points in 10 RPM increments
d. Raise and lower rev limiter in 10 RPM increments
e. Reduce shift duration (time delay during gear change) (+/- 25% and anywhere in between)
f. Increase or decrease shift firmness (+/- 25% and anywhere in between)
g. Correct speedometer for gear changes and/or tire sizes
h. Turn on cooling fans at lower temps in incremental steps of 1 degrees (for vehicles w/ factory equipped electric fans)
i. Adjust top-speed limiters

The Predator allows the end user to adjust the following parameters:

Timing Table 2000-4000rpm (+15/- 20%)

Timing Table 4000-7000rpm (+15/- 20%)

Fuel Table 2000-4000rpm (+/- 20%)

Fuel Table 4000-7000rpm (+/- 20%)

Idle (+ 500rpm / -300rpm)

Speed Limiters (Trucks Only)

Rev Limiters

RPM Shift Points

MPH Up and Downshifts

Shift Timing and Shift Pressure (Please note, however, the U7194 and U7191 do not have communication with the Transmission Control Module, and cannot adjust parameters related to shifting characteristics.)

Re-Calibrate Speedometer for Gear and Tire Size Changes

Please make sure you choose the correct year of your car, using a Predator on a car that is was not designed can damage the BCM. For each model year listed below, the Z06 Engine will work with the Model year Predator.
