LS1 Edit : Reversible ?
I bought a '04 Z06 yesterday, and I am planning a few simple mods (Borla Stinger cat-back exhaust + Halltech air intake). For tuning, it seems to be a consensus that doing an "LS1 Edit" is the best way to go (compared to Hyperchip, Superchip,...).
But can I quickly reverse the modifications done to the computer ? And re-activate them afterwards.
I ask because this is something that will void the GM warranty, so if ever something goes wrong with the powertrain (it shouln't for the small mods planned), I want to undo the changes done to the computer before bringing the car into the dealership. Or will a dealership notice that the car got LS1 Edite-ed ?
Thanks for bearing with a newbie. :cheers:

The first thing you will do is make a file of your cars program and save it in a number of places for safety, a floppy for certain. You can input that file anytime you wish. Also, set up a folder to save a file of each change you make.

File backup

But can I reset the computer myself, by purchasing a small computer that reads that file so I can re-program the car's computer at anytime ? I have no idea what is envolved here, thanks for your input.

Re: File backup (jerome)
I suggest you find a good used low cost laptop. You should get one with a serial port. Adapters can be undependable. A floppy and CD drive would be helpful if your using a desktop as your main computer.
With Edit you do the programming.

Re: LS1 Edit : Reversible ? (jfpilla)
Hope this doesn't make me look like an old geezer but jerome are you sure you want to delve into LS1-Edit yet ? LS1-Edit is a vey powerful program that will give you COMPLETE control over you PCM & unless you are 100% sure about what you are doing you might ( & probably will- I assumed such from your post ) wreak havoc on your PCM/Engine/Tranny. Why don't you start out slow like most of us do with Handhelds ( Predator is a very good choice here since it allows you to make minor changes within a controlled frame ) to get a better understanding then you can later upgrade. Just my opinion. :seeya
P.S. A handheld will let you go back to stock in a snap. :yesnod:

Re: LS1 Edit : Reversible ? (V8_Club)
Good point, I would not want to get in over my head here, and surely getting into LS1 edit myself would do just that.
But I was wondering is if I could easily reverse the changes done by someone else who knows what he is doing. That tuner said he can do that free of charge in 15 minutes whenever I want, but that taking the car in for maintenance, the dealership would not notice anyway with their diagnostic maintenance (Tech 2 ?).

Re: LS1 Edit : Reversible ? (V8_Club)
Jerome is an engineer. He will have no trouble with Edit itself. In fact the issue is not Edit. It's an easy tool to use. The real issue is do you understand tuning and knowing what you want to do to the cars program. It looks, however, like you are planning simple mods. If that's the case, it might be a practical question and you might be better off spending less and getting the Predator.

Re: LS1 Edit : Reversible ? (jerome)
Should be undetectable. See with LS1-Edit the first thing you do is create a back up copy of your stock PCM program that you can " Revert/Recover " if the need arises. I would think it works in a similar manner like restoring a back up of a say hard disk image. Unless you know it was done you have no way of telling so. TECH2 is a diagnostic reader I haven't heard of it being able to do such a thing. BTW : THe Predator guys in fact recommend you take it back to stock before sending it to the dealers then revert to Performance tune once it is out. :reddevil However, its use on a '04 Z is under debate. You might want to check with them first.

jfpilla I agree LS1-Edit is a great program. I just believe that it requires the person to be 100% aware of its capabilities with experience & understanding of tuning under his belt before delving into the same. :steering: I is on my wish list but until I'm sure I will be able to use its power correctly I will continue to learn on this forum & from LS1 Edit FAQ.

True, I'm an Engineer, and I have learned with time, not to get into stuff which is "over-my-head" which is why someone else would be doing this work, not myself. I just wanted to know how easily I can revert the PCM back to normal if needed.

Re: LS1 Edit : Reversible ? (V8_Club)
Maybe the sound of the Borla Stingers will be enough to make the service guys suspect more modification. Maybe GM dealers don't care until you want to make a warranty claim, and then they bring out their army of diagnostic tools.
BTW, thanks to all who participate in this discussion, I learn a lot from these exchanges, if only to start asking the right questions.

Re: LS1 Edit : Reversible ? (jerome)
No prob. It is always good to exchange opinions. I would have to agree that checking the PCM every time you take your car in for an oil change etc. would be useless. It might be like you said the dark weapons only come out at the " ahem " :rolleyes: time.

Re: LS1 Edit : Reversible ? (jerome)
...but I am curious on how easily a dealership will pick up on a PCM modified by LS1 Edit.
I too am curious about this.
I've had several problems with my 02 and do not want to void the warranty: rolleyes:
