Also noted during testing that de red dot in some maps are not correct reading things and if you chance numbers of rows or map size things do not work any more so yes there is some work to be done there.
Did you try lower the numbers in the Fuel request map on low engine load request?
Also taking some timing out on low engine load will help smoothen things out.
Also put both minimum injection quantity to zero I never use them but do not know if this will be a smart thing as I did not develop the control strategy for it. I run some test on my ECU test system and it made in better with the on/off thing with injector duration.
Thing is if the car is jerky your getting a lot more pedal movement than you think. Have some data from a project and if you did not know better you think the driver had Parkinson. LOL. But must say making some serous low end power dos not make a diesel tune and easy job. Some of the rally things we do we run a hi ready state of boost like ALS on a rally car only without the bang bang sound but getting smooth power transition dos take a load more settings in general but up to 300Nm/1000cc displacement we never used it.
As for popping in the exhaust again this is something to look up in a data log.
Hope this will help.
