If the throttle response is bad enough & there's no available tools to adjust the throttle response via DCAN, then I might opt for hardware like the Pedal Commander. I'll send an email over to MHD to see if they'd be interested in producing software for the N51/N52. |

Never saw this post before, we have a fairly long thread in the track subforum related to issues getting a throttle blip during heel-toe downshift.
https://www.1addicts.com/forums/show....php?t=1833057 I will say though that throttle response under normal driving conditions is excellent on my car (N51). I'm running the Stage FP tune, euro airbox, silicone intake boot, and AA headers.

Yeah, the more I think about it a 3IM isn't going to help. I'm convinced there is a delay purposely built into the throttle's reaction time.
I may break down and try the dreaded pedal tuner, but I really don't want to change the throttle mapping. I just want to eliminate the damn delay.

I went ahead and ordered the BMS pedal tuner. I doubt that I'll use anything but the lowest setting, but maybe it will fix some of the dead pedal feel.

There is still some slight delay, but I run my power box on MAP 3 and it definitely moves a lot faster that it does on MAP 0, which is stock. My motor mods are - Euro box, turner intake boot, Berk Race exhaust, BMS PBX. I'm in a n51. |

Ultimately my goal is to re-map the throttle to be linear, I don't know what the stock curve looks like but I hate when pressing the pedal past 50% barely anything happens because all the response is up top to make it feel torquey. Adding a pedal box might inflate this issue at the cost of removing the delay to make the throttle more responsive. But keep us updated on how this works out. |

The BMS might actually help our cars in this regard when it comes to blipping the throttle for a downshift. It's not a true fix, but maybe it can mask the problem slightly. Time will tell...

Pedal mapping and lose the CDV - cheapest fix
However the 3 stage intake conversion and a Stage FP tune will take care of the throttle mapping and transform the driving experience and fun factor Big Time.

Yeah, that's been their position for years.
To get anywhere with the N52 you'd need the help of someone like hassmaschine who has done quite a bit of deconstruction of the MSV70/80 or start from scratch with a damos file like imported_mega talks about in the other thread.

So I installed the BMS this morning and the results are satisfactory. There are three stages and within each stage there are three further levels of adjustment. Stage 2 and Race mode are way too aggressive in my opinion. They feel very artificial and it's somewhat difficult to modulate the throttle from a stop.
Even the standard stage 1 is just a little aggressive in my opinion. I dialed it back one click from standard stage 1 and that seems to be the sweet spot. I'll try it for a week and then go back to stock to see how much of a difference it makes. My goal was only to remove some of the delay inherent in the BMW's throttle programming. The BMS isn't really a fix for that, but it does help mask the problem. It's now easier to blip the throttle for a downshift. You can tap the throttle instead of punching it half-way to the floor before the engine does anything. I really wish there was a true fix, but the 3IM may also help a little when I get around to installing everything.
