That's correct, on the earlier build ECU you can use a tuning platform of your choice, like ecutek, mhd, bm3, etc

So say I did that, any idea on cost? And would there not be a mileage discrepancy if I put the original ECU back in? Say for service at the dealer.

If you are getting the ecu bench cracked I'd say you should be expecting to have trouble with the dealer. CBS will be fine but warranty...

does anyone know what exhaust is on the red m4 in the video? It doesn't sound stock. Sounds really good.

From what I understand the original ECU is not tampered with, just read and the contents written into a new older gen ECU.

I think it's stock with burbles which they can do with the tune.. or maybe a dp? I can ask for you? I follow them on IG

Why do you think that? I never change my cars back for normal dealer visits. If you have a major problem, they are going to void your shit anyway since it's tuned. ( Engine/tranny)

It's always strange when the warranty comments randomly come into the discussion. Everyone should be aware of what they're signing up for.

The new Diagnostic software BMW uses will immediately flag a car for being tampered with. My friend sent his 340i in for warranty repairs and the field engineer called and told him his scanner showed that the DME had been flashed 40+ times. Then they still ended up honoring his warranty.

Whether it's an ECU swap or a flash tune they have ways to see what's going on. It all depends on how deep they have to dig and whether the dealer is mod-friendly.

To clarify I was asking about the cloning process and if by having two ECU's one unmolested stock ECU and one tuned unlocked ECU the original ECU would have issues due to a mileage discrepancy between the DME and Kombi if it was reinstalled, I never said I was worried about warranty.

Once one company can flash it only a matter of time before other companies figure it out. Best option is to wait I think.

Doesn't matter about mod friendly. If you have any major problem, your buddy at the dealer can't do dick. They will bring someone in or send info to BMW. They are not going to cover a major repair if you tampered with the car. Just tune it/ enjoy it and if something happens, man up and fix it.

I heard a Porsche guy had that Happen. Thought he could swap out to stock ECU but got nailed by something not matching up. Lol

They replaced his entire cylinder head. Lol. Meanwhile, my dealer wouldn't warranty my OEM tail lights because I bought them from another dealership.

Like I said, it depends on the dealer.

You got hosed. You bought something from another BMW dealership and your dealership wouldn't cover it? Very odd. Change your dealer ASAP

Absolutely will not be going back ever

Absolutely.

But to this day, many people think tuneX or piggyY is somehow invisible and BMW won't be able to see what's up.

You pay to play, end of story. If people were honorable then BMW wouldn't have to go out of their way making ECUs 'uncrackable'

How would jb4 be visible to the dealer if you take it out before visiting them?

Because it's not a matter of whether the JB4 is installed or not when you bring it in.

The ECU is like a black box, once they check it, they can see all the parameters and see you ran outside the factory parameters, adding boost, etc etc. Zero way around this.

It's stupid simple, if you need your warranty and the risk of running outside it bothers you, do not tune the car/run a piggyback. Always assume it does void the warranty because in 90 percent of cases it does unless you have that "cool dealership".

They claim it's not and its very difficult to find anyone who can prove otherwise or has been voided after removing it. Also very easy to find reports of flash tunes who have been voided. Either way it's always hotly debated. The last person I saw on here who got voided for JB4 was because he posted about it on facebook and the dealership pulled his facebook posts and handed them back to him when he tried to make a claim.

Darwin for sure.
