Weird throttle closure. Too much torque?

aajjeh · 01-30-2026, 10:40 AM

Hi yall,

Having a huge throttle closure around low-mid range rpm. Not exactly sure why, but have heard it could be related to DME seeing too much torque? Idk. Pretty new to the BMW world. Log link below.

Describe 'throttle closure' (hesitation?). The issue isn't presenting itself at WOT during your log run? I run a JB4 set-up which can be quickly set back to factory tune. Not sure if you can easily do that with your MHD to see whether the issue is present at factory tune setting?
