It's always hard to sell a modded car, especially if the mod was an ECU tune.
You can return most modded cars back to "stock" -- ECU tunes included -- but unlike most hardware mods, an ECU tune's shadow will always be there.
Personally, I wouldn't ever buy a modded car of any type. There's just too many choices out there, esp. when it comes a run-of-the-mill 911. Even if the the price was "right" it most likely wouldn't convince me.
Now that it has been established that there is practically no instance where a reasonable high end ECU flash upgrade has caused damage to a 992 or
has affected the warrenty,
What problems will there be in selling the car, both in and out of the warrenty period ?
Will buyers avoid such cars ?
Will this car be desired by collectors ?
How much financially will be lost from a stock version of the same car ?
Are you looking to have your car tuned? Is that what is generating the threads and questions?
Who started another thread to argue about tunes!
It is simple, just like if you should track you car.
It is all about trade in values, or money.
If you can afford to take a hit, do it, enjoy.
No garage queens in my life.
My 991.1 2014 Turbo S, 60k miles, 1/2 track miles!
Porsches take a beating, car has been over tune, de tuned , etc.
As long as I can buy the car from the dealer CPO and that they disclosed that it was previously tuned and passed CPO anyway, I wouldn’t care. I just want the warranty coverage for the time I own it, and want the confidence that when I trade, the dealer won’t give me **** for a previously tuned car that they sold me. When I traded in my GTS, the sales manager asked if I had tuned it. I said no (true) and he asked why not? LOL. Come to find out, he drives an Audi S something that is tuned. When I traded my GTS, it had an AWE switchpath exhaust but I offered to have them reinstall the PSE and return to stock. They wanted the car with the Switchpath.

I also would not buy a modified car - especially a tune. My reasons may be different from others - first, I find the stock car more than adequate for my needs. Second, if the car was modified I would wonder how the car was used during the time the previous owner used it. I do think that the cars are robust enough to take a tune but why do I need to get a tuned car? If I wanted a tune, or any modifications, I would prefer to pick them myself. I also go back to selling my M3, which I had tuned and modified the suspension. I had a lot of trouble selling it, even though it was low mileage and meticulously maintained. I eventually had to return the car to stock to make the sale. So, no modified or tuned cars for me.
I absolutely love the 992s, best 911 to date IMHO.
I will certainly be tuning when I get mine. Trying to decide whether to go with the "S" as originally planed or possibly the base model as they appear to respond extremely well to tuning. Tough call at this point.
If you return it to stock, I am not sure how anyone will ever know the ECU was tuned. It requires a deep analysis of the ECU that can only be done by Porsche to detect a tune.

It's actually pretty easy.
The PIWIS can detect any altered ECU (even after its been returned to stock), and most PPI would/should include a PIWIS scan.
Well, after four years of happily driving my Adventurine Green 2020 Porsche 991 992 C4S, I have learned the consequences of altering my computer with an
AMR ECU upgrade. In all this time, I have been treated to extra power and performance with no difficulties.
In Ohio, we have E Check. I was contacted four years after my purchase to have this check before getting new license plate tags by my birthday.
At first, the car was declined because I had not driven it hard enough. So for the next three days, I was tearing up the highway, which is safely done
due to my laser jammers. Then I brought it in to E Check, believing it would just be a formality and I would be on my way.
Unfortunately, the Technician said there was a problem and I was directed to to manager in the office. She told me, that what I was about to hear
would be best said by a Manager in Columbus. He told me since I had modified my computer, my car was now illegal. Even if I returned it to stock
it could never pass once this judgement would be made. To me sure, I approached my Porsche Dealership where I had purchased the car, new
four years prior. They told me that they would never be interested in buying my car, although it is pristine condition, as it could never be certified.
I called my mechanic, Jeff. He proposed sending the ECU back to AMR and have it return to stock. Now it could read the twin exhausts on my
Akropovic dual exhaust system. He then drove it hard for five days and finally took it to a friend who had a plug in E Check Kiosk. It passed !
He provided me with the authorization from E Check and his itemized bill which showed all he had done. Lo and Behold, my dealer is now
interested in buying my car. Although it can not be certified for sale, it still will be easy to sell. The warranty would be up in a few months and I decided to order a new 2025 fully loaded Porsche Macan GTS.
The dealer will buy my car for about $130,000.00 and the Mecan will be about $113,000.00. I expect the dealer will sell it for at least $160,000.00, Given that I am trading in my car, I will have no
sales tax on the new car so at 8% tax, I will save an additional $9,000.00.. a great deal !
IF I could go back to the beginning I would NEVER modify a Porsche again. It's just not worth the trouble when you sell it.
nice thread revival. So Ohio’s stance is once the ECU mod is made it is forever illegal to register in Ohio even if returned to stock? Wouldn’t such a thing be tied to the VIN and therefore the new owner would not pass e-check in Ohio as well no matter what you did? Something just doesn’t add up here
Remind me to never move to Ohio.
