i need help with dissabling anti jerk or at least i think. Yesterday i converted from ms41.0 to ms41.3 following all the steps in openms41(big thank you and respect for the hard work to all the guys on this project). flashed full, read partial and tuned it to siut my engine (m52b28 in a e39) but i have a few problems and dont know how to solve them. car runs and idles like normal. but when i want to start from a stop it drops rpms almost to 0, sometimes stalls (no good in a crowded traffic im usually in :mrgreen: ). But if i start driving car is very sensitive to throttle, starts accelerating at around 12% TPS which i can manage but its annoying to try keeping the foot on one spot.

Biggest problem i have is jerking under hard acceleration. car starts jerking at 3000rpm to around 3500rpm like theres a kangoroo in the trunk lol. if i pedal it slowly past 3000rpm all is good. i tried dissabling antijerk maps in ignition timing but anything i do doesnt affect it much. last tune i flashed had antijerk rpm limit somewhere around idle and ignirion retard of 0 in the whole table.

can someone guide me into right direction? im just looking to have that crisp throttle response and ability to "fly past" when needed. also car is a weekend drift lemon and i noticed a biiiiiig loss of torque 2000-3000rpm

any help appreciated

hi. Strange. I also have 2.8, but I downloaded the ms41.2 firmware, one person posted it here on the forum, it is in the public domain. And I'm fine with the car, and even I would say it's better than the ms41.0 in terms of driving sensations.
