Diablosport Predator Tuner for 2005-2008 Dodge & Chrysler Hemi (See Applications)

Tune your Hemi for more power!

What is the Diablosport Predator? The Predator is a state-of-the art, high performance tuning flash programmer in a sleek handheld design. Once connected to the vehicle, the Predators internal computer recognizes the vehicles 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.

Dyno Tested Performance Tunes Average power gains are in the 15-20 RWHP range. 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 vehicle 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.

** Note: You may want to purchase a Serial (U7777) or USB (U7778) cable to connect the handheld to your computer for updating purposes. These units include the proper power supply. If you need either of those, we stock them and the prices are $31.95 for the U7777 and $40.95 for the U7778.

WOT Spark 1k-3.8k: Allows user to adjust timing +/-10 degrees in the 1000-3800 rpm range WOT Spark 4k-4.8k: Allows user to adjust timing +/-10 degrees in the 4000-4800 rpm range WOT Spark 5k-7k: Allows user to adjust timing +/-10 degrees in the 5000-7000 rpm range To properly dial in your timing using the Predator you need to log or monitor the following live data parameters. Spark, this is your actual timing (in degrees) at any given time. Knock Retard, this the amount of timing removed (in degrees) due to knock (detonation/ping). The knock sensors can in rare cases pick up other harsh engine noises as well, if this is the case it is recommended to fix the cause of the noise before proceeding. You basically always want the knock retard to read zero under wide open throttle conditions, it is normal for it to show some KR when stomping on the throttle and also during the shift. Monitor the spark and the knock retard pids under wide open throttle and see if you have any knock retard, anything higher than 1 should be adjusted in the respective timing range in the Predator , if the knock is severe, 5 deg plus, try lowering spark by 10%, if less than 5 deg, try 5%. Make another wide open pass and monitor the same pids and basically keep doing this until you seen no knock retard. NOTE: The use of respective grade fuel should be used with tune choice. 91 octane tune will run on 87,89 and 91 octane. The 93 octane (Performance) tune will run on 91 and 93 octane. If severe knock cannot be remedied by adjusting the parameters for it, try to install the factory tune and monitor the knock using it. If knock still is present consider switching fuel brand. DiabloSport recommends using fuels from the following vendors: Mobil, Sunoco and Amoco/BP. Knock Sensors Disabling the knock sensors can cause severe damage to your engine if used with poor quality or low octane fuels. Short term Knock sensor enable/disable: Enable or disable the short term knock sensor. Long term Knock sensor enable/disable: Enable or disable the long term knock sensor. Fuel Adjustment

Tire size adjustment The Predator has two different ways to adjust for tire size. First Method Enter your original tire size then enter the new(actual) tire size. The Predator will prompt you to put in your original tire size in metric format (ex. 265/75-17), once entered the Predator will then display your entry and you confirm it by pressing enter. The Predator will then promt you to put in the new (actual) tire size in metric format (ex.305/50-22), once entered the Predator will then display your entry and you confirm it by pressing enter. You can now press esc to go back to the main modify parameter menu and if no more adjustments are desired press esc again and you will be asked to install modified tune, press yes and let Predator upload new adjusted tune to your vehicle. To reset the tire size, you can go to reset parameters and then reinstall the tune. Second Method Enter the tire size or the overall tire height The Predator will ask if you want to adjust it via entering the tire size or by the actual tire height. Tire size, enter the metric tire size displayed on the side wall of the tire (ex.265/75-17) then press enter to confirm. You can now press esc to go back to the main modify parameter menu and if no more adjustments are desired press esc again and you will be asked to install modified tune, press yes and let Predator upload new adjusted tune to your vehicle. Tire height, measure the tire height using a tape measure and enter that measurement in the Predator, then press enter to confirm. You can now press esc to go back to the main modify parameter menu and if no more adjustments are desired press esc again and you will be asked to install modified tune, press yes and let Predator upload new adjusted tune to your vehicle. To reset the tire size, you can go to reset parameters and then reinstall the tune.

Quick Adjust parameters Quick adjust parameters do not require a reflash to take effect, they require a key cycle, these parameters are available in a separate "Quick Adjust" menu item as well as in the modify parameters menu. User will be asked to cycle key after each adjustment. ESP mode Enable or disable the ESP (traction control), NOTE: When disabled the ABS, ESP BAS and (Brake) lights will be illuminated and ABS will not be operational Reset TCM adaptation Resets the learned TCM adaptation(instead of pulling a fuse). Shift Points Raise shift points by a predefined setting, 5.7L's (1-2 5800rpm, 2-3 6000rpm, 3-4 6000rpm), 6.1L's (1-2 6400rpm, 2-3 6400rpm, 3-4 6400rpm).(N/A on Jeep) Shift Firmness Reduces torque management between shifts for a firmer shift , N/A on SRT8 vehicles. Autostick auto upshift Enable/Disable automatic upshift when in manual autostick mode, ie. raise your rev limits and you can shift manually at any rpm without the vehicle automatically upshifting (as it would do stock).(N/A on Jeep)
