https://www.spool
& street.com/threads/advanced-throttle-response-mystery.7721/ Then there is this one: https://www.spool & street.com/threads/throttle-response-increase.5183/page-5 Looks like the thread originated on here actually... and n54 mhd has added a flash time option. Don't think the same has been done on N55 yet... XDF needs to be defined and I doubt anyone did it for N52 given the smaller market. Seems like the N52 tunes are bare minimum tweaks not advanced DME reverse engineering and defining of all relevant tables. Maybe the above isn't relevant at all too idk but for sure there is some kind of logic at play. Last edited by bbnks2; 09-20-2021 at 07:28 PM.. |

The new MHD 1M throttle option is better than stock but there is some room for improvement but AT THE TRACK this weekend I noticed I had perfectly good throttle response under hard braking. Until then, any ABS intervention meant almost dead throttle (only enough to hold the rpms its at) when trying to downshift rev match. I know it doesn't help anyone without an N54 but it suggests you should keep digging. |

I am seriously considering doing an n54 swap just because of how stalled E-n55 tuning is... Can't be THAT hard, right? |

This turned into a pretty big issue for me yesterday at VIR. It was consistently happening into turn 1 and less consistently at turn 11. But, I was trying to work on my braking specifically and not getting an expected throttle blip was less than ideal.

I'm glad others are experiencing this and I'm not going crazy. Getting to the bottom of this will be big so please share all the info you get!

Stumbled onto this thread, and I had similar issues at an airport autocross event this summer. I had a couple issues going on:
1) I was pulling the shifter over too far on the 3-2 downshift and getting it into reverse. I can fix that by driving like less of a hack (and also buying a shifter with a reverse lockout, LOL) 2) I found the brake pedal does really weird things when I was HARD on it. Like it went extra hard and had no braking, did that a couple times. Really unnerving 3) During downshifts, I did notice I had to double blip to get the RPM I wanted out of the blip. This was in conjunction with issue #1 a couple times so I wrote it off to that. Co-drivers also experienced this same issue. EBC yellow 200TW 245 tires Unknown 3SIM tune (but no 3SIM ) |

But yeah when it happened to me I let off the pedal (after first panicking) and then got back into it and the pedal was stiff again. Luckily there is run off in turn 1 of Limerock to play with and keep it on track. |

Ice mode is rare, you have to do things just "right" to get it to engage. Happed to me in my Mini race car at Daytona. Big dip in the pavement entering T3 and I was fighting to wrangle it back in.

Talked to Stage FP and they said they are aware of the issue but do not have a solution for it If anyone finds out anything please update the thread.

Also, @phloozy, did you code out all that brake crap like engine power cutting when brakes overheat, etc.? |

As I mentioned in post 20, coded brake settings have nothing to do with the issue Phloozy originally asked about. The issue is in the tune and only happens at-speed on track under the right conditions.

When, in an emergency, you apply the brake pedal quickly and with force but without really further increasing brake pressure, Dynamic Brake Control (DBC) instantly builds up maximum brake pressure, bringing your BMW more quickly to a halt. https://www.1addicts.com/forums/show...&postcount=156 So, on track, this was happening to me where the car assumed I was emergency braking and would utilize all of the braking power, even though I didn't want it. So in a braking zone, I would end up much slower than expected by the time I got to the corner/apex/etc. Once I added the min value the car no longer intervenes.

Phloozy I'm definitely not pushing as hard as you do, don't have the same grip level, but when first taking my car on track the brake pedal was so inconsistent that I worried I'd made a mistake thinking I could track the E82 reliably. DBC was the last brake setting that I changed and it made the pedal much more predictable and consistent, that was 2 years ago now and it's been great ever since.

I changed mine using NCS Dummy but you can probably do it in protool. Changing the value to the min level reduces how much the car intervenes during emergency braking.
Stock, mine was Wert 01 value E4 and I had to add a line to make it Wert 01 value 00. The hexadecimal range is from 00 - FF, so the stock value is pretty far up the range. Back to the thread topic, I was at CMP yesterday and had issues with throttle blip when braking for turn 11. On that track, turn 11 is at the end of the highest speed section and it's a heavy late braking zone. I just keep hitting the pedal with my heel until it blips.

Any chance you've seen anything in the N51/N52 DME file that prevents the brakes and throttle being applied at the same time but only when doing heavy braking?
