Throttle Delay Fix
Hi all,
I own a used 2011 X3 xdrive28i (N52 engine). I've had it for just less than a year now, and while I love the car, I do notice that there's a 0.5s delay when going from a stop to acclerating. It's pretty frustrating, and sometimes dangerous if you don't anticipate it (i.e. turning left at an intersection). I do find that switching it to sport mode helps, but it's still present. I also reset the transmission adaptation using Carly, in an attempt for it to adapt better to my driving style. I've done some digging, and I guess this is a not uncommon issue. I did see that BMW released a software update that could be obtained at the dealer (since I bought this used, I have no idea if it was updated), but not specifically for this engine. Does anyone have any experience with something like Sprint Booster (https://www.sprintboostersales.com/S...r_V3--SPRBM014). It's a plug-and-play device that you route into your acceleration pedal, and it remaps the throttle response. I'm wondering if it would be a relatively easy fix to my issue (and I'm also wondering if there's any risk for damaging the car by using it). Otherwise, I'm wondering if anyone else has any fixes to this issue. Thanks! |

TBA (Throttle Body Adaptation) RESET - solution to Throttle Lag
For those of you who have noticed a 5-10 % throttle lag ( not turbo lag ) when accelerating, there is a "cure" which is called the TBA reset:
That should tell you the reset is complete. Start the car and go notice that the "lag" is gone. The first 5 - 10 % is now engaging the transmission. YMMV so this may or may not make any difference for your vehicle. |
