Are ECUtek and Uprev tunes reversible
 

Hola members. I'm thinking about investing in one of these 2 tuners. My question is, are these able to reflash the ecu back to stock calibrations after being flashed? I don't have too much experience with reflashes, just piggybacks like the aem fic. Also, has anyone had any issues reflashing back to stock in the event that they needed to have warranty work done at the dealer?? That's my major concern and deciding factor for these tuner softwares. Thanks in advance.

yes it is a button click on a laptop and it goes back to 100% stock.

Thanks for the reply bud. Do you know if there's any issues if any dealer warranty work needs to be done? Like will anything pop up showing that the ecu has been reflashed by an outside source?

not sure. I don't go to the dealership for work except when I did my steering lock recall and tranny fluid change since I don't have the proper tools for that.

however both times were after my tune with full exhaust, no cats, and intakes. nothing was said to me about it on the recall trip. the tranny fluid change was not warranty type work so nothing they really could have said then besides thank you for your money.

If the dealer really wants to check, I'm pretty sure they can find out. But it's not something they encounter regularly, so I'm guessing most don't look for it or wouldn't catch it. But if you're looking to file a warranty claim on any part of the engine, I bet they do :twocents:

I've had a headliner replaced under warranty and they didn't say anything about my tune. I'm also in the beginning stages of transmission replacement under warranty and the dealer hasn't said anything yet.

considering they want to charge $200 to hit a button to upload new nav software I'm sure its not worth their precious time to check for a tune file in the ecu.....

fuckin hate dealerships. :shakes head:

Very true. I know that they won't check for anything like that but if I have a sensor failure where they need to test monitors or run some sort of diagnostic, I wonder if that could cause a red flag. I still have a lot of warranty left and I'd rather not void it if at all possible.

technically they could cause a fuss about it. really depends on the dealer/mechanic.

Very true. I see that you're still N/A with a tune. How would you rate your gains from just a tune alone? I've seen mixed numbers. Some are fairly substantial and some are only 10-15 hp which really isn't worth it imho

From what I've read, the tune isn't really about peak numbers. People who have one will swear it was worth it for the improved throttle response alone.

Definately understandable. It just doesn't seem that cost effective of a mod for the price for such a minimal gain. You know what I mean?

Totally understand you. My 2 prior cars were both turbo so I know all about spending a few hundred bucks and getting a big bang for your buck with some minor mods. Truth is these cars are pretty maxed out from the factory. You are only going to do so much with a N/A 3.7L V6.

You also have to account for the other features an ECUtek tune would offer. Valet mode, launch control, multiple maps for different octanes. I plan on getting one eventually. Going to do tune and HFCs all at once.

Jesus....... really? They charge that much to do that?

$99 for the actual update and $99 for Nissan labor to press a fuckin button to load the file. Pretty messed up right? Wish I made $99 for 10 seconds of work.

I"m definately considering it. I would love to go turbo again but the price tag is a bit insane right now. lol. Eventually it will happen.
