OK I did load the 87 performance tune and seem to go good and I can feel the difference My ? are to change to a different tune I like the 93 performance tune do I just plug the xcal back in and just let it over write the first tune I uploaded or do I need to flash back to stock then load the tune oh 1 more ? and I don't have to leave the xcal plugged in all the time just when changing tunes right?.Thanks guys

 

I am new to this too, so wait for a second opinon. But first thing, make sure you are running on 93, run the 87 down and then fill up with 93 before flashing, but you probably have already done that. You do not have to leave it plugged in unless your data logging. I am not sure about the other question, but it seems like the X3 will do a backup of the stock tune if it needs to.

 

i got my xcal3 today too, loaded the tunes and the truck wont run = [
i emailed justin back my problems and look forward to having the right tunes asap!

 

you flashed back to stock, right?

 

yeah, it works fine now, but i really would like to have the tunes in working order, i have to go to san antonio tomorrow morning and really would have liked to use the economy tune i ordered = [

 

I had this same problem and it since he was so busy it took about 2 weeks to get my tunes fixed. My new tunes work now. My problem was that the PCM was flashed by a Ford dealer at some point and I didn't know it so the PCM had a different equizzer value that what it would have had if it was stock. Justin wrote the tune as if the truck's PCM had its original factory settings and that is why it didn't work. After I gave him the strategy code read from the XCal3 everything was fine. Make sure you send him that strategy code. Good luck and I would like to hear how your problem is resolved.

 

Ok back to my stuff and ? now guys LOL

 

hahah sorry I sidetracked your thread. I actually just got my VMP tuned XCal3 yesterday and have some of the same questions as you about adjusting the settings and that is why I could not answer your question. I will keep watching this thread to see what other opinions you get.

 

when i went to change from one tune to another to see if one worked or not, i just went to one tune, found out it didnt work, then back to stock, then try a different tune, found out it didnt work, then back to stock.

 

I can only talk about the Gryphon/Edge Shane. (And the only reason I'm posting is so you know you're not ignored and to keep the thread hot).

I KNOW you don't have to leave the XCal plugged in though.

In the case of the Gryphon, you can switch between tunes directly, without going back to stock in between. I strongly suspect you can do the same with the XCal. If someone doesn't give you a yea/nay soon, I'd just see if the XCal lets you do it this way, and if it does, assume it knows what it's doing.

Most of these devices, if they're at all reputable, are not going to let you do something that will hurt you. I put the XCal in the reputable category.

yeah I just wanted to make sure its a lil nerve racking messing with the CPU of my baby I would cry if something messed her up LOL but so far so good I'm going to swap to the 93 tune after I run out the 87 to see how it is and my hats off to Justin he was a big help and kept up with me in emails thats how you run a business and thats why he slammed with work

 

Now my new ? is where do I put that sweet chrome SCT emblem at ?

 

Yes. you can switch between tunes before going back to stock.

And as for the emblem....mine went in the recycle bin.

 

i emailed justin the tunes didnt work and i also included the strategy code and sure enough when i got home, they were waiting for me, after installing all the software, i loaded them on to it and then hooked it up and it works perfectly! i love them! glad i got the tunes, i was able to test out 87 perf and 93 perf and holy cow! night and day difference, hands down best mod to date! every truck should be custom tuned!

 

oh yeahhh..custom tuning s the way to go.
