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.
