I am new to tuning using the predator and have a couple quick questions.
1. Is it true that you can not see the actual air fuel ratio using the predator? Do
you actually need to add a wideband instead?
2. Where can I find a list of what all the acronyms mean on the Predator? I had found it once, but can't remember where I saw it.
3. What does the predator call the actual timing? Is it the spark advance?
4. I can make adjustments to the provided Diablo tunes correct?
5. Does anyone have any fan setting numbers for the 180 Tstat on a 6.1 Challenger from the Northeast part of the country? Everything I have seen is from Cali and the Southwest.
Thank you

RE: Basic Predator Questions
1) yes. The predator shows commanded afr. You need wideband to see actual.
2) don't know. Somebody will.
3) Yes. It's "actual spark ..."
4) Doesn't matter where you're from or the weather there. You set fans to the t-stat and not ambient conditions.

RE: Basic Predator Questions
Answer 2- under help in Data Viewer, go to contents and scroll down to Real-Time data. The list of acronyms is the last item in that menu.

4. Yes, you can make adjustments to your tune with the predator.str5010 wrote:I am new to tuning using the predator and have a couple quick questions.

5. I have tried many fan settings for my 180* stat and finally settled on 184* for LS fan and 194* for the MS and HS fan. With this, my HS fan cycles from time to time but doesn't run constantly. I tried 181* and 188* as some have suggested, but my HS wanted to run almost all the time.

DCX Predator parameters explained
We dedicated this page to explain the different parameters that the Predator allows the end user to adjust.
Please note that all parameters listed may not be available on all part numbers.
# Cooling Fans AC off
# Cooling Fans AC on
# Spark Adjustment
# Knock Sensors
# Fuel Adjustment
# Rev limiters
# Idle Speed
# Vehicle Speed Limiter
# Tire size adjustment
# Quick Adjust parameters
Cooling Fans AC off
* High MPH HS Fan On:
High MPH High Speed Fan On when ac is off and above 8mph
* High MPH MS Fan On:
High MPH Medium Speed Fan On when ac is off and above 8mph
* High MPH LS Fan On:
High MPH Low Speed Fan On when ac is off and above 8mph
* Low MPH HS Fan On:
Low MPH High Speed Fan On when ac is off and below 8mph
* Low MPH MS Fan On:
Low MPH Medium Speed Fan On when ac is off and below 8mph
* Low MPH LS Fan On:
Low MPH Low Speed Fan On when ac is off and below 8mph
Cooling Fans AC on
* HS Fan On:
High Speed Fan On when ac is on
* MS Fan On:

Spark Adjustment
* 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:

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)
