U7135, cannot update, sold to me out dated, spent 60 bucks to get cables, and none of your programs worked, blogged to get help, no answer, called to get help, hung up after 20 minutes on hold...getting as fed up as possible, and trying not to swear, help soon or it is going back, and buying the competitions devise.

If it was sold to you out dated. Go back and tell them that, get one that is updated. Don't just be pissed off at home, do something about it.

Where did you buy it from? $60 for cables? It shouldn't be nearly that much. What time did you call? DS is in Florida and they close at 5. It is annoying that their phone system doesn't tell you that though, you just sit there on hold.

These tuners can be alittle challenging at first. I think the impression is that it should be just like plugging in a cigarette lighter. Thats not the case, sometimes they take some work, but WELL worth the results. Mine took me about two months to really understand and get my truck tuned right. Getting the tune in the vehicle is just the START, you then will need to maximize it for your car/truck. You get out of this thing what you put into it. I wouldn't think of driving a stock truck again, everyone that rides in my truck knows its way better than stock and a lot more fun to drive.

What I've read is you need to go back to r12 and update from there. Make sure your on a windows pc.

I am going back to where I bought it, I got it just before I went on holidays, and just got back last night, so today is going to be the day of action...I called just after noon mountain time, so there should have been someone there, makes me mad still that i went 5000 km on holidays, and this thing wouldn't work, was looking forward to the added performance in the mountains.

Thanks for all the suggestions guys

What's even more rediculous is that you made this post over a week ago and no one from Ds has bothered to reply. Completely unacceptable.

x2. doesn't surprise me one bit. i notice they answer the easy questions but when there is a serious issue they are no where to be found.

This may be a stupid question but is there a tuning manual? Any written doc's something to go on so i can stop going in circles. I mean all i read is complaints as I look for answers. I guess its my fault I didn't join this forum before I purchaesd my unit. Had I done that I dont know that I would have spent the money. I love the idea of this I love the adjustability. with out a manual of proven setups its not worth blowing up my pcm! I as others are on the LX forum and I've been starting threads looking for answers for over a month. If someone could please PM me with the manual I asked about or some way of learning please HELP!!!

A good way to learn is to go through the Modify Parameter menu. List the parameters. Google them for an understanding of what they do and how they interact with the other parameters. When you get through that you'll have a basic understanding of the parameters to tune your engine. Then take some logs and see where you're at and what you want to change.

If you're just looking for a cookie cutter solution for your mostly stock car then that's all been done for you and included in the Predator performance tunes.

Ding, Ding, Ding we have a winner!! The first person to show me the way to help myself!!
Thanks you da Man!!

Here's a list of the parameters, taken from challengerforumz.com.

Predator parameters explained

This page will 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:

Cooling Fans AC on

* HS Fan On:
High Speed Fan On when ac is on
* MS Fan On:
Medium Speed Fan On when ac is on
* LS Fan On:
Low Speed Fan On when ac is on

)NOTE: DO NOT ADJUST FUEL/TIMING UNLESS YOU KNOW WHAT YOU ARE DOING)


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.

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)
