I did have a jb4 on the car and before I took it to the dealer I had gotten it taken off. The only thing BMW told me was that the software was tampered with so they weren't going to cover the cost of the engine. Tried to get more info from BMW but they wouldn't tell me anything else.

Ok, so you have a JB4. Which one? I think based on your profile you have the N20 engine. So that leaves you with either the stage 1 only, or the map changeable stage 2. If you had stage 2 and you didn't uninstall or clear the codes before taking the JB4 off, I could see them finding out. Since your car seems to of died because the engine was being overworked and over heated, then they could prove you had a tune that did damage the parts that were broken. Now what I don't get is you telling us that they denied you and didn't give you a reason. See you said this was 25 grand. Unless your some rich kid that lives off of mommy and daddy or you have some ultimate money making job, 25k is a lot of money. The dealer would have sat you down and went over what was found and explain to you why your warranty was voided. They wouldn't just tell you no and make you leave. You have a legal right to that information. To my point of 25k being a lot. I know I personally would have been screaming and kicking until I got to the bottom of things. I wouldn't have left out of there without knowing ALL the facts so I could figure a legal way around it.

Now if you coded your car, that wouldn't have caused the engine to blow up (talking about coding it to close mirrors and such). So I wouldn't even worry about that. Plus you can deny it and say a guy at bmw did it for you.

What I would like to know honestly is the truth. If you really did blow the motor, what were you doing when it happened. What did BMW say the root cause was? Were you racing and using your paddle shifters to late at redline rpms?

Any of these systems can be detected by BMW, even if you remove teh units and clear error codes.

Your average BMW dealer tech cannot do it, but when there is a large claim like a entire engine BMW themselves take a data dump from the car and check all parameters.

They will then pick up parameters that have been exceeded by the aftermarket system.

I have seen this done on a couple cars over the years.

So even with a Bavarian Tech tool it would be detectable?

Sounds more like they are looking at engine data over error (tuner) codes.

i did have it coded by frogman. all codes were what BMW does themselves. none of the non supported retrofit ones that would have voided warranty

From what my mechanic tells me I have the n26 motor and I was running map 2. Before I took it into the dealer I had gotten it removed and uninstalled.

they wouldn't tell me why other than the software looked like it was tampered with. The service manager didn't even know because they wouldn't tell him either.

What dealer? Because that is horseshit. The service advisor knows especially with a big thing like engine "exploding" and the fact that you haven't said what fuel, or what happened (rod through block for example) makes me think this is crap. No person just rolls over and accepts a "idk they don't tell me" explanation. I would call BMW NA and get then involved.

Instead of trolling us, why don't you either tell us the truth about what happened or give us details on exactly what they said went wrong. Engines don't just explode and drop and drag at cruise speeds. Piggyback or not.

I was driving 80-90 mph on the freeway in comfort mode (auto shifting) and when i got off the freeway I was driving 40 mph when it occurred.

i believe thats what they did with my car but they wouldn't tell me exactly what the issue was. Even my service manager didn't know what was going on.

Its entirely up to you whether or not you want to believe this or not. I sat with the service advisor and the only notes on car show that the software had been tampered with. I had taken it to a mechanic before I towed it back from the dealer and they say it looks like one of the rods (i think #9) came loose and smashed my oil pump down and resulted in my oil pan breaking.

I'd guess they found some sign of modification on the car, a loose bolt from the intake, the coding, evidence exhaust was changed, or something along those lines. Still they should cover a thrown rod. It's not like tuning is going to cause that. You'd have to fight with them over what caused the rod failure. Are you sure you didn't over-rev the motor somehow?
