I haven't seen this addressed lately.

This is from another forum. The guy took his "08 JK to the dealer for the tranny temp flash:

"Also those with Superchip Flashpac when putting things back to stock it does not change everything back to stock and the dealer was nice enough to mention and make a note that looks like my computer was modified or messed with somehow."

Anyone here had a similar situation?

 

Some of the programmers change things that if not put back to stock, it could jeopardize the reflash, and maybe even your ability to use the programmer again.

I don't know if the ProCal changes critical stuff or not.

You should put everything back to stock before you take it in.

 

Before you take it to the dealer- disconnect the battery and leave it that way for a minute. Hook the battery back up. Your Procal settings have now been restored to stock. It shold not mess with the re-flash IMO

 

I have never flashed a cpu but I do know that some car companies(specifically hear VW/Audi) have found out ways to find out if they cpu was ever touched in the programming. I read a write up in some mag a couple years ago because dealers were complaining about getting burned on cars that were traded or returned that were flashed and then returned to stock and having issues because they couldn't sell as a Certified Used. Don't know how they were able to tell but some footprints were left behind and I don't know if the flash packs now have been updated so they don't leave the footprints that were being picked up.

 

My procal has a return to stock function on it. Just have to set the dip switches to the correct config and then your procal should return your comp to exactly the same as it was before you used it. You also have to do this before you can use your procal on another jeep from what I understand.

 

Like many other electronic devices I feel that if you hack/reprogram it in one way or another even if you go back to the stock settings, if someone is looking deep enought there are electronic footprints that can be found somewhere someway along the path. It just depends on how far someone looks.

But in any case I'd like to know if disconnecting the battery resets the Superchips Programmer in the same way it does the Procal?

I'd really like for one of the Reps from one of the programmer companies to chime in on this talk about the footprints left behind and if this issue has been brought up at all with the JK??

 

Since the AEV-Procal isn't a programmer, or programming anything you will be fine. It only modifies what is already there compared to things like the Superchips one where you actually overwrite fuel mapping, etc...

 

Your dealer, if he is any good, CAN tell when you have done anything to the CPU. The Mopar test equipment, Starscan, has a digital signature it sends to the CPU upon authentication and at disconnect. The CPU keeps track of authentications that do not send this signature. My mechanic actually showed me in the report on the Starscan server in the shop. They CAN'T always tell what you have done, but they know you have been there. My mechanic didn't exactly say the following per se, but he hinted at it, emission scanners and OBDII code clearing machines show up as no signature authentications. So, if you absolutely have to take your Jeep to the dealer, an inspection sticker dated the same day the computer shows the flash would be a plausible explanation...

 

Flashpaq saves factory settings and recommends you reset to fac settings before any dealer visit. So they can tell you were in there.... big deal. If the service center denies something because they "think" you modded some setting... find another service center. Some service managers look for any excuse not to cover warranty issues and some do not.

I highly recommend the Superchip flashpaq. Lots of info on the forum here about them. I love mine and the way my Jeep drives with it.... and it gets better the more I drive...

 

To be precise the Flashpaq saves the settings of the PCM before you program it with the Flashpaq. So if you change a setting with something like a Procal first, it will be stored in "stock" settings profile when you use the Flashpaq.

And I agree with Yippie21, the Flashpaq is worth the discussion with the dealer.
