My 116i started to misfire slightly (idle roughly) and hesitates when the gas pedal is moved, after a MHD remap, but only for a few seconds after a cold start.
I changed the plugs for colder NGKs, fitted Ignition Projects multi spark coils which helped.
I just live with it although I have yet to see if it is better or worse in cold weather.
(I probably should reverse the remap and see if the idle is still rough to prove it is this)
I think the delay before the symptoms started is probably due to the ecu adaptation. Remapping resets them.
