okay. i have a 2001 ext cab with the 4.2L

and heres my question its pretty simple....
Whats a Gryphon do?

I've looked and looked but i cant anything on what exactly they do.

 

Yep, it is.


Did you read the "sticky" threads at the top of the Tuner section? That should help a lot. The Gryphon is a handheld devise that comes with a mounting dash pod so you can use it as a monitor. It comes with canned tunes to replace the factory tune in your PCM. It can also be custom tuned by PHP to fit your specific truck and your modifiications.

 

With the 4.2L v6 you'd be better off to go with a SCT xcal3......and custom tunes......

 

and still.. what exactly is a "SCT xcal3"? and what will/does it do?
Ive read the sticky and still don't completely understand the whole concept... Sorry...

 

bottom line, makes your truck better. lol thats the simplicity of the idea. of course these guys will go into deep detail when it comes down to it. it changes your pcm to make your truck run and shift better. simple. lol

 

Or perhaps you could fire up Google and search for SCT?

Or maybe read the SCT owner's manual?

but im sure you can always ask they guys for more in depth knowledge once you've actually got some info and learned the basic concept. there smart guys that know what their doing, but they wont bottle feed you. lol

 

All of the aftermarket tuning devices allow for adjustment of the vehicles preset computer tunes. Most provide 3 options: more, more better, and best.
These tunes adjust shift settings, fuel, and air flow, etc. to compensate for installation of aftermarket parts like cold air intakes (CAI) and cat back exhausts and more. They are quite easy to install and operate. In addition several of the devices allow for monitoring of parameters that the computer monitors. It's basicly just looking over the shoulder of the computer while it does its thing. Several of the members sell theirs on the forum when they upgrade or get a new truck. They do not wear out so it can be an affordable upgrade and fun too. Hope this helps you.

Caveats:

The end user cannot adjust for airflow, not can he safely or effectively correct for a Washoobi (CAI/WAI).

Further, while most of the above can be done by most devices, most folks should leave the settings as-shipped unless thay are conversant in, comfortable with, and can actually properly measure, what it is they are changing, and why. The exceptions, or course, are the basic things like yer gearing and tire size - these should Always be confirmed, as does the specific octane which you intend to be running, and the intended usage - (no towing on a Perf tune, fer instance).

Additionally - for true *custom* tuned devices, such as Xcal 3's Gryphons, etc, the tuning shop will already have optimized the tunes based upon yer requests (performance, towing, econo tunes, etc), and specific vehicle PCM strategy code - hence there is really nothing further you need, or should, adjust. This includes proper corrections for any aftermarket components - a Washoobi being one of the more crucial (other than forced induction, lol).

Lastly - there are some folks here with the knowledge and skill to tweak their own tuning - including writing Transfer functions for intakes - but the expenditure (software: SCT Advantage for example - and A/F analysis tools: Innovate widebands for example - for starters) and learning curve precludes this as an option for most folks. But it IS an option if you are so inclined, and have a tuning shop willing to work with you.

Thanks for your observation. One thing I wish we could adjust is idle speed. I hate to pay for a custom tune just to raise a few RPM. Erik

 

Ah - but you can, sir;

For SCT devices, at any rate, these are the end-user adjustments - this includes their 'canned' and custom tuning (it can vary a bit between the two).

hey MGD. i went adjust my idle rpms on my edge evolution and it some numbers came up but it wasn't like 1000, 900, 800 or something like that if i call recall right so i backed out of that mess for the time being. i would like it to idle about 700-800 if thats safe of course? lol i like the way my truck sounds idling about there and i haven't read through my edge manual fully yet so i'm sure theres a logical explanation and any-who can figure it out. i'm just looking for some quick advice and make sure the 700-800 range is safe and if you recommend anything. thanks

 

Yep, and you can change the idle of both canned and custom tunes with an Edge and Gryphon.

 

Hi bud.

There are 2 idle adjustments - one fer idle (in gear) and one fer neutral/park. Mine are in the 600 rpm range ( 5.4, though - may be different on a 4.6).

Not conversant with Edge/Gryphon interface - but perhaps the nice Ol' Codger above will help y'all

BTW - you should not need to adjust it ...
