What is the optimum gap for NGK 97506 on flex fuel? I hear .020 is the best for E85 use, but since I am planning to switch off between 91 and E85, can I still run .022 or gap down to .020?

I am curious to know what that "happy medium" is as well regarding FlexFuel usage - with the understanding that the happy medium spark plug gap will not be fully optimal for an E85 specific tune or 91/93 oct tune, but ideally would be more than adequate. When the time comes for me to execute the FlexFuel hardware upgrade, I will be operating my M3 anywhere between a stock CS tune up to a BM3 Stage 1 tune, using fuel grades between 93 oct and E85, on the street or on the track.

I have slot 1 set to full E85 map and slot 2 is a 93FF map. Cary and I have gone back and forth a few times about running the various maps and so far he hasn't advised changing from the 0.020 gap recommended for the NGK 97506 plugs with E85 tune.

I know it's off the latest "BM3" tangent but...
I've heard the "MHD" has this. Does "BM3" have a flashable Launch Control function for MT cars?

Anyone know what the criteria for GTS Start-up roar is? Sometimes the car does it, sometimes it does not. I thought it might be related to hot vs cold starts but I've seen inconsistent results. Yes, I have it enabled on my latest flash. I do have all of the OEM settings enabled for cold start and such as well. Maybe that's interfering?

Sorry, cold start is a universal setting across all modes.

"boost control changed - more boost to redline" I'm about to be on Pures this week and i'm curious of the same as ALCOBENDAS and how these changes may translate to a dyno and/or what the new expected boost #'s would be.

"The previous map would taper boost to redline. This will maintain a flat 24-25 psi to redline 🙂"

What are you trying to do with ReFlex+ that requires BM3 support?

I'm not particularly well-read on the subject but mentally preparing the next list of things I'd like to sort out after this round of revisions on my setup. Fueling will continue to be a limiting factor for me.

Another great part is the ReFlex+ can watch the RPM, Boost and LPFP pressure info coming from the DME and to ramp up a piggyback LPFP. This is way better than using a simple Hobbs switch. Again, if something goes wrong the ReFlex+ can trigger Limp Mode instead of you leaning out an engine (boom).
