SOS! weistec sc low rpm jerky
hi guys..
my car is 2014 c63 with weistec s2 sc. MBH lth and akapovic mid-rear exhaust. ECU tune is TPE tuned and it is good.
stock idle rpm is around 700-750. car just jerky climbing up a slope on low rpm.
so my tuner increase 100 rpm on it..but did't solve the issue.
i'll attatch the video clips...
hopefully someone could tell what is going on....thx..

couple of things...
- what is up with your tune where you have a HUGE dip in power in the lower RPM's...
- from the sound of it without seeing the tune file, it sounds like you're running PIG rich.

When was the last time you switched out the spark plugs, 02 sensors, or replaced your MAF sensors? The car sounds like its running super-rich and not getting enough air. This can be caused by failing sensors preventing airflow to the motor.

So car has ran great for 2yrs with this setup. Or new issue since new setup was just installed?
I'm going to go with needs a new mct unit. shockingly not that expensive on the parts side but trans has to come out.
However air / fuel issues will cause this if the adaptations are out by more than 1%
