Sprint Booster?
 

I just saw this "BMW Sprint Booster" from ECS Tuning that is supposed to remove some of the throttle lag in the drive-by-wire throttle. I have an E70 35d which has the notorious lag from a standstill.

Has anyone tried this on the 35d or any of the turbo X5's? I'm curious to see if anyone's experienced some improvement in the inherent lag.

+1. I would be very interested. The lag is ridiculous and often dangerous (those left turns).

From what I understand, all the booster does is change the amount of pedal travel needed to apply X amount of throttle.

Being a bit more liberal with the throttle pedal would accomplish the same thing.

Then it wouldn't get rid of the horrible pause. No matter how liberal you are with the pedal, the pause is there.

That's not something I've noticed -maybe the 4.8is and X5M don't have the same issues?

I did not have a good experience with SprintBooster (on my 2008 X5 4.8i). I have a long post about that.

I can say that when I reset my throttle response, the X5 was noticeably responsive and smoother. I think that I probably need to do this annually (I only did after owning the X5 for 4 years).

How did you reset your throttle response??
