Actually racing the vehicle on a race track is a violation of the warranty conditions and I've seen customers declined repairs for it. So keep it on the down low.

The day I don't get to fully enjoy my M3's is the day I switch platte forms. 👍

Hi, are you sure about that. Insurance and lease vehicles will be restricted.BM encourages to race on track.

HPDE is not 'racing' and I think there was a case BMW tried to deny a warranty claim on a motor which blew up during an HPDE and then eventually covered it under warranty after being fought back. If they recently changed their policy I'd like to know.

So we were able to real-time the engine and all is well. Luckily nothing made contact and everything was intact. Thank you all for the input.

Awesome

It would seem that when the hub spins it just slips the timing and does not cause catastrophic engine damage, tuned or not tuned. Of course, there may be the odd case where it does.

Good to hear! Get a crank bolt capture plate installed at the very least to hopefully prevent this from happening again. Hope to see ya at NJMP in August.

Once this happened, can I put bm3 stock to take the car to bmw?

Returning to the stock map, does bmw detect that it was already tuned?

Yes once you flash the car there are flags left behind in the gateway module, trans module, DME, and others, so it's easy for them to detect. Sometimes you get lucky and they don't check but with something this expensive you'd have to get really lucky.

do yourself the favor and upgrade your hub!

its such a terrible feeling babying this car when all it wants is for you to beat on it- upgrade for the peace of mind.

Same here.

Fixed back seats with 6 point harnesses and halos, MCS suspension going in, sticky tires, PFC BBK... completely stock ECU

I run the car on the third DCT setting and downshift like I'm at the racetrack when I'm there... this is the whole point.

If the engine blows I will get a new one as I'm fully covered by warranty

This is a blatant lie

Tuning the car means you are automatically out of a warranty if/when the engine blows

If you participate in competitive events, like an AER race, then your engine warranty is void. HPDEs are not competitive events no matter how much money Porsche drivers sink into their cars trying to be faster than M3s

Most 3rd party tuners (BM3 and Frieling-based cables) only flash a particular area of the DME (or DCT), no i-step updates are performed or flash counters are increased. Piggybacks can also be detected (even after removal), no one particular method is more immune than the other if BMW already suspects the car is tuned. Every case is different.

For stock platforms under warranty, that's what warranties are for - let BMW handle it. For those keeping their M3/M4s for long term or seeing track use/aggressively driven/adding power, look into getting a Crank Hub Kit (regardless of brand) installed.

I spun my crank hub on 2018 F80 at approx 12000 miles. Was on boot mod custom tune.

Just some info about crank hub kits. The VTT fix has failed twice that I've heard of. Once on a heavily tuned stock turbo n54, and another on a single turbo n54 I believe. I haven't heard anything about the maxpsi kit or the gintani kit failing.

N54 is irrelevant. One of the vehicles you are referring to was actually a drag car, equipped with aftermarket harmonic balancer and no CBC. Here's some more info on these threads.

Chris@VargasTurboTech should be able to provide details. TBH, I haven't heard of any manufactuer's kit failing on S55 (Gintani, MaxPSI, VTT, etc), other than the TPG kit, which was discontinued long ago.

VTT also offers a No-Slip guarantee: https://f80.bimmerpost.com/forums/sh....php?t=1621073

The "No-Slip guarantee" is a joke: If the hub slips, they'll replace only the crank hub kit, not your engine or repair any of your engine damage. Kind of pointless as it's not guaranteeing that it will fix the problem which would be the damaged engine. No one cares about it guaranteeing a cheap part that was supposed to do the job in the first place.

EXACTLY, it's like saying, "Hey, buy our gas valve for your house, guaranteed no leak! If it does and your house blows up, we will replace the valve for free!"

65,000 miles... stage 2 tune..full exhaust, csf intercooler.... no crank hub mods at all.... no issues

We haven't heard any failures about the original splock when used with the CBC. The stock turbo failure is news to me, the single turbo drag car was used without a CBC. Regardless, the design has been improved upon since and there are no failures reported or even rumors that I've heard. Once more, though, splock and CBC are to be used together as a complete solution.

Are there any splock failures reported when not used with CBC?
