I think the aftermarket programmers use the s/n so that you cannot use it on multiple vehicles. Like loading a program for a friend ect.
I know that if you brought it to a dealer, they could tell. The PCM will have one S/N and the vehicle another but I don't think the computer knows what vehicle it's in.
I'm just guessing here. I see some for sale at different used parts suppliers. I'll try calling some and try to get some answers.
I was thinking that it's so easy to pull one out that if you found one, same year, model ect and use that one to add your tunes to then you could put the original back when you go to the dealer for service under warranty. That way they can't tell that any engine damage was due to you playing with a tune.
Just thinking out loud. Any feedback would be appreciated.
1) Think of a PCM as a hard drive that needs a dealer star scan to format it before you can use it in your truck.
2) Tuners don't leave a trace when removed, so your point is moot
3) If they did leave a trace, how would you know the PCM you bought didn't have one if it came used out of another Ram?
4) I have never heard of anyone with engine damage caused by a tuner, period.
5) ....and Most important,
If you break your shit because you modified it IT SHOULD BE ON YOUR DIME TO FIX IT!
Show some freakin' Intergrity man!
