Maybe double check with BMS if they have a map where boost can go higher based on ethanol sensor input like for instance with meth. Might be worth looking into..
When is the E85 map going to be officially released?

I think I finally found a vendor within driving distance I'm comfortable with. Should really help me get this going.

This flash tune sounds awesome and I could get it done locally but this goddamned Crank Hub issue is keeping me from pulling the trigger. So fucking annoying

I'm worried about it also. There is another thread floating around about a recent crank hub failure from a 2016 build.

Yeah, I was just about to pull the trigger on this and saw that. Really very frustrating.

Whats Bootmod3 got to do with very very rare crank hub failures? The recent failure is on a bone stock car.

I just feel like if I do spin my HUB I have a better chance of getting it fixed under warranty than if I have a broken-in-to DME.....

Unfortunately I feel the same way. I've been waiting for the nicer weather to jump on BM3 but this recent spun crank hub has me rethinking things. I know it's rare but it's still a possibility.

I look at it differently. There is also a chance of getting run over on the street or getting into an accident both of which are probably higher in probability than spinning a crank hub. In two years almost now its what like less than 10 cars if that? Thanks, I'll take my chances just like crossing the street or driving my car risking, but not everyone is the same I do get that.

Good point, two question and sorry to thread jack!

lol.

1) If a crank hub is spun, and is not covered under warranty, what's the cost? (Approx)

2). Once the DME is cracked open and the tune is installed, can you "refladh it" back to OEM?

Thanks. Really wanting to go with this Flash tune

Yes thats the big seller point of Bootmod3 being able to flash back to stock on your own without needing to visit anyone.

It's not the only tune that allows you to flash back to stock on your own.

^this is the real problem. Like Chewy basically said to each his own. Everyone is different regarding risk vs reward and how far they are willing to go.

+1. This is the key point for warranty-worriers when it comes to flash vs. piggyback tunes (or tune vs. not).

With a flash, be it BM3, Hex, or one of the template tuners using the Euro-sourced file, if you flash back to your actual stock map or the dealership updates your DME, you'll get the 'DME tamper' code. You can flash back to a stock performance map using BM3 (not sure about VF) but any digging whatsoever on BMW's part will quickly put that little lie to bed.

Long story short, as soon as you unlock the DME and flash it, it's really game over for being able to flash to undetectable stock mode. That's just a risk you have to take if you want to jump in to the performance game.

On the piggyback front, I'm guessing it would take about 2% more effort on BMW's part to determine if there was a tune or not.

Based on that, if you're tuned, I wouldn't bother flashing back to stock or a stock performance map if taking your car in for service/warranty. The damage was already done.

Even with a piggyback they can see the tables have been changed and the boost was raised at certain rpms meaning there has been something adjusted. Point blank if they want to know they'll find out.

Tables aren't changed with a piggyback. Boost will also report as stock as the signal to the DME is interrupted by the piggyback. Other parameters will be altered though which is the telltale that there was a tune in place.

Well.. if there really is a big tamper code that pops up after a flash where any general tech can see it I would say thats a lot easier than shipping the ECU/data off to BMW to find the JB4 traces. I do not believe any BMW dealer techs have the ability to get that deep into the ECU logs.
