Challenger SRT Hellcat
How much does a new ECU/PCM cost and where is the best place to get one? So I can have one opened up for a tune and still have a stock one for a trip to the dealer.
How will they tell? If I keep the OEM one that came in the car and put it in before taking to the dealer for service?They are still going to be able to tell that you have swapped ECU's. So unless you're on great terms with them at your dealership you are probably going to get popped.
Mileage of your car is tracked not only on the dashboard computers but also the PCM. They won't match when you put your stocker back in. I'm sure it also tracks every time you fire the car up, go WOT and more.....you're in IT, you should know, everything's traceable.How will they tell? If I keep the OEM one that came in the car and put it in before taking to the dealer for service?
You go right ahead and keep thinking that.But I still don't think there is anything in these cars that has memory without power outside of the ECU (the only flash memory device). It's a Dodge, not a fighter jet/submarine. Everything else wakes up in a new world every day (every time it has power), just like a goose.
Like you, I have an SRT tech who says 'I see nothing', he claims its up to the tech to bring the issues up to the service manager/FCA. But if the issue is big enough (whole motor replacement) it wouldnt surprise me if FCA did some serious homework, including flying someone out to inspect the damage.So there's no way to get around it without getting stuffed on the warranty? Why are others buying additional ECU's then?
If your an IT guy/gal worth their salt and have no idea that FCA is going to be able to figure out something simple as a ECU switch, I have to ask are you self taught?Lol. I make my living with IT. You think I'm not in 'incognito' mode? I'm off the grid...even when I'm on it...haha.
for a swapped PCM, only if I look for it but then it's pretty obvious. a tuned PCM is a little harder but still detectable.
