Hello & welcome!

Would you mind describing how that is done, exactly? Are Maf TF tables available for insertion, or specific tune files with same incorporated for a specific list of CAI's (the only way I know of to correctly & safely accomodate a CAI).

Thanks

The predator comes with built in CAI tunes for Airaid, K & N, and Roush. So there is nothing you have do to the MAF tables. Although if you wanted you wanted to change the MAF table that is possible by adjusting the parameters.

 

Interesting.

Direct access you say? For the canned tunes? Do you have a link elaborating on this functionality?

What If I were to add a non-supported CAI? What then, for the canned tunes?

Do you work for Diablo? Or, are you a tuner?

Thanks again.

Cheers.

No I don't work for Diablo, I'm just a guy that enjoys his truck and think that Diablo has a great product. I'm also not a tuner.

Here is a link for the predator. http://diablosport.com/index.php?mod...display&pid=56

It doesn't give you that many details on it, also forgot that JLT CAI are also supported, However when you go to load the tune it give you the option to add the CAI tunes.

I haven't ran any other programmers, but I have been highly satisfied with the product and support the diablo offers.

Thanks

 

Guys, as I have mentioned, our canned tunes are developed to a point that most other companies would not consider.

When we develop our canned tunes for the F150s and Mustangs, we contact the popular CAI manufacturers and have them send us some CAIs.

Then, first things first, we put them all right on our IN HOUSE flow bench.

Each intake is flowed, to create a 'MAF curve', by measuring the Voltage output of the MAF as airflow is increased.
Using the flow bench helps us see things like turbulent spots in the airflow, or odd spikes in voltage output, before it goes in the vehicle.
Once we have a good MAF curve developed on the flow bench, we can simply enter that curve inthe tune, install the intake onthe vehicle on the dyno, and voila, we have CAI tunes that are 99% dead on on the first try. A couple pulls and some datalogging gets the curve 100% perfect, and allows us to provide canned tunes with a level of development that rivals most 'custom' tunes.

In the case where an unsupported CAI is used, a custom tune would be the best bet, as with any tuner.
The Predator does offer a global MAF adjustment parameter as well, which allows you to increase or decrease the entire curve by a certain %.

 

couldn't have said it better mike

 

MGD - I've had a look at the manual for the Predator. It comes with 4 canned performance tunes that were written to be used with or without 4 different CAIs. So, in effect, you get two tunes with it - one for 87 octane and one for 91 octane and you choose the pair that match your CAI configuration.

In addition, it allows you to bias the WOT fuel tables toward leaner or richer fuel settings in two different RPM ranges (2k-4k and 4k-7k). This is an open loop adjustment obviously and the manual warns that you should not make these adjustments without proper test equipment - wonder how many customers will follow that advice?

There is also a provision to download a tune you have onto a PC and to send it to Diablo or someone else with the proper knowledge and equipment for "tweaking", after which you can upload it again into your truck. This could compensate for minor differences in CAI design.

So, it's not quite a "direct user accessible" control functionality, but it DOES seem to extend the "canned tune" concept into the addition of CAIs - which, when you think about it, should not be too hard to do. I'm guessing the tables are probably somewhat richer throughout for CAI tunes.

And, I would think that almost any of the other programmers could be modified with a menu addition that would provide this functionality.

One thing I like is that the power gain claims of the Predator are rather modest: about 15-20 RWHP. So, no wild claims.

Overall, this has all the hallmarks of a quality product in my opinion and I suspect we're going to be seeing more on it now that DiabloSport has become a site sponsor.

Edit: DiabloMike got his post in before me. I THINK I wasn't too far off base and thanks for the input Mike. If I said anything that was out to lunch, please correct me.

Hi folks.

Yes - I was looking at that as well. And I noticed the same caveat w.r.t the 'warning'.

Ado have a couple more questions though.

How would you account for trucks with known strategy issues - TEM7 box code trucks for example? There are several others - most of which do not adhere to commanded A/F's (typically much leaner).

Having said that - for a user who is reasonably versed in the topic of the vast diversity of the F150's factory tuning, who wishes to ensure his truck is optimized and safe adding a canned CAI tune - what does he do next in terms of collecting the required info and feeding it back for analysis & correction? You can be as detailed as you wish right here, or refer me to any technical dissertations on the subject, because I really am curious and intrigued - this degree of control in a canned environment is promising.

Lastly - are the canned tunes 5, 6, or 7 digit strategy matches? My SWAG is it's 5-digit for generisized tuning. Please correct me here.

Thanks again - as I also indicated earler, more exposure, more info and online presence will go a long way in overcoming the historic 'inertia' around Diablosport's products.

The same was the case years ago with SCT's products, and then more recently with Edge's products and it's spinoff, so this is not something targeted specifically at your company, Mike.

And - it's not a gauntlet you need to fear to run. Familiarity, open & honest disclosure, tool use and tuning adjustment assistance & advice - all for the better. Okay?

Thanks once again.

While I am not personally familiar with issues specific to a given box code (our Ford tuners may have some more relevant data on that subject), we test on a large cross section of vehicles before we release anything, and try to test on at least each 5 digit family to ensure repeatability. (Yes, the canned tunes are based on the 5 digit match, but custom tuning is based on the stock file, and requires a full 7 digit match).

Anyone who wants more info has the capability to datalog with their Predator or Trinity, and logs can be played back on the tool, or uploaded to our Free Dataviewer Application.
Check it out, there are a few sample logs in there to play with...

I am all for open and honest disclosure, please let me know if you have any other questions and I will answer to the best of my knowledge...

 

Mike, Jack, Corey, and all of the other tuners who drop in here on a regular basis, it is really great to see everyone openly discusing their products. It woul be very easy to bad mouth each other, but instead, everyone, joins in and gives us the information to make informed decisioions, concerning which products are best for us. Thanks to everyone for keeping these discussions open and informative.

 

Good, except I'm NOT a tuner! I AM a Moderator and Bluejay and I are pleased overall with the way the forum behaves itself. I have to say the forum DOES do a pretty fair job in presenting information. Things weren't always this way!

So, a big thanks to all of you for making our job pretty easy.

- Jack

 

Jack I know your not a tuner, but you are a huge proponent of PHP, but still remain give credit where credit is due.
