How are the guys with the JB4 liking it? Is it worth the money? Noticeable power gains?

Have been lazy and haven't installed yet. There aren't any instructions or any photos really to show where all connections are located. Honestly that's the only thing stopping me

Whats with the huge undulations in G force at the launch? Is this due to wheelspin? The speed graph doesnt look S shaped to indicate poor traction. Wondering if the car is cutting power intermittently vs the dragy not registering properly. Do you have other runs?

Let me reassure you before you install this. There is no "might". As soon as you use this device even one time, your car is flagged and you will no longer be receiving a warranty on anything BMW can pin to the tune. It does not matter if you unplug it immediately after your first pull and never use it again. Not trying to dissuade you or anything like that.

No, I don't have a tune on mine. As much as I would like BMW to allow this, they are not the only ones who are "strict". Realistically, why should they pay for an engine repair when the engine has been pushed in a way it was not designed for? Think of all the ethanol mixed, map 3, doing 0-60 pulls right after a cold start cars on IG out there.

i personally never once got flagged. But I am hearing they came out with new guidelines..... but you would probably have to break something that has to do with the JB4.... they cannot stop servicing your car unless it was relevant to the problem

Yes, they have to prove the tune caused the problem. However, they have much deeper pockets than you or I, so if they say they won't cover, good luck.

Your not covered! You blow the engine and you had a tune for 1 pull, get ready to fork out the money. You have no leg to stand on. Just tune the damn car and enjoy it. JESUS, lol. If you can't afford to fix it, or you will be scared every time you drive it, don't tune it. Not rocket science. Or just buy a faster stock car. Wolf is correct! The data is in the car. They will know
