Are canned tunes safe/recommended for daily drivers or not? Okay so basically, this is the 14 megaton question when it comes to handhelds, and I'd like the answer:
Is it in fact "safe" (as in not damaging to the engine/maybe even better for it?) to run a canned tune on a stock/light bolt on setup? I don't know what has been done in this tune whatsoever and for all I know I could be on the brink of an engine meltdown (lol, not likely but who still...). I noticed one thing is that under torque management parameters in the "performance tune" (keep in mind this is SLPs version of the Diablosport) I could turn it "off", "on", or "no change"? "No change"? That tells me that it's reduced in the performance tune but by how much, I don't know.
It seems like I could either turn tm off or on when modifying the performance tune, but for some reason I can't simply reduce it.
So basically I'm back to square one, TM being just ONE topic of concern for me. Is it safe to put my faith in SLP and Diablosport and just install the canned tune and be done with it? Or no?
*incidently the manual that comes with these handhelds is a joke. I don't even know what parameters were adjusted in the performance tune.
for ex. when I look at the following parameters (within the performance tune)
1) shift speed and 2) shift firmness they both read "0" at the center of the scale. Is this the "true 0" figure from the stock tune? Or is this a figure that has already been modified in the performance tune and now doesn't truly reflect "0". Has it been touched at all in the performance tune or do I have to do that myself.
I'm a little frustrated with this product and really am lost when it comes to how to use it and what it does. The end user would benefit from some actual documentation and instructions to be provided with such a product.
Sorry for all the ranting but in reality I just want to be sure I'm not damaging my vehicle. I know modding adds stress, but I don't really race much these days and just want a little extra "pep" is all. But not at the cost of engine failure etc.

SLP spent a lot of time developing these calibrations based on the bolt on packages they sell, so I would have no worries about running one of these tunes with good fuel.
The '0' is referencing where we set that parameter to in the performance tune, so if you increase it, you are adding to what we did, or taking away from what we did if you decrease it.
I'd suggest you hit our support forums for help with using the tool, you'll find all the answers you need here:

The real question at the bottom of it all is, is -your-
vehicle, its base tune, its mods and their effect on
state-of-tune close enough to the stock or SLP-
package baseline to not get you into trouble.
I looked at the old version Predator tune after I
got HPTuners, the significant difference was about
+6 degrees of across-the-board timing push. That
is what gives you the seat-of-the-pants impression
of increased performance and some actual gain.
Whether or not your motor wants 6 more degrees
at every load-point, can tolerate it without ping
when summer rolls around, comes down to details.
Everything from did you port your MAF like a dumb
*** because it was free, to did you ever change
your fuel filter or clean the debris out of your radiator.
I'd say to just give it a try, listen for ping, scroll
the monitor screen down to the KR lines and look
to see if it's pulling timing at part and full throttle.
It's unlikely you'll blow anything up (no warranty
on free advice) right off. But think about what
you have going on that the programmer doesn't
know about.

Well I think what I have on my car (not much) very closely resembles the power pac stage one option from SLP. So that's close as far as mods go. But I don't really no how to read the predator while driving (still new at this) and will probably hit up the Diablosport forums again (already a member there) just to see how I can tell what I'm looking at in terms of whether timing is being pulled or not. (I wouldn't even know what that looks like on the screen yet
)As far as listening for pinging; that's a hard one since my car (like many LS1 vehicles) has a distinct pinging in it until operating temp. I don't know if the pinging you're referring to is similar to "piston slap" or not.
*damn , the more I want to find out, the more I realize I don't know
Thanks for you post, I'll take your advice.

If I decide to turn the shift firmness down on the performance tune, it could still be higher than the original stock settings correct?
I want to get the interface cable at some point soon , but as of now I will have to settle for real time data on the screen. Thanks again.
