I don't have this problem.

Try this (or +/-) for the load to torque tables (all 3).

Do you have a log?

Probably, but I don't know which will go with the changes. I don't keep very good order/records. And a log now would be useless, I'm on lowered boost/Winter tune.

I target around 28psi on Summer tune, stock turbos.

I suspect post-shift timing pulls in the winter and not in the summer may be caused by torque limits. You can build a lot more torque from cold intake air in the winter and hit those limits, possibly. Hence the reason why @chrisdfv has a winter tune. (I should too, but haven’t gotten around creating one.)

Corrections due to torque limiters won't log under the timing correction parameters though, will they? As far as I know only correction due to knock does.

My car is manual, but it showed the same sort of corrections post shift, and only on pump gas. Recently though, I realized that the bin I used to make my map originally came from an automatic car, and there were a large number of differences between my car's stock bin and my custom one that didn't correspond to any of the currently defined tables. I copied over all my defined table changes into the stock bin, flashed it, and now the corrections are completely gone. So, for what it's worth, there may already be an undefined flag/table that modifies timing reintroduction speed/whatever is causing this issue.

it's in my MHD work queue

I just found this thread by luck. I am experiencing the same issues here and would love to know if you are still working on it or in which queue position this topic is right now :D

Those differences were likely just due to an update of your rom version. There should be no differences between an AT and an MT bin, as the required differences are in separate tables (not different tuning to the same tables). The DME looks up coding at start, and if an AT, references those tables when required vs. the MT tables.

Would increasing torque reduction and setting shift as fast as possible in xhp help with this ? This way if the dme stock parameter would stay same but trans completes shift quicker so it would have torque intro after shift completes?

This is how I have mine setup, i rarely have post shift corrections.

Hi Guys
I'm new to the forum so I'm not sure if I'm posting this in the correct place. I have some questions regarding timing corrections on my n54 135i 6MT. I initially flashes the 95 octane map and had some correction under WOT. I was then told to flash the 91 octane map and see the results. With the 91 octane map I started getting more corrections at lower boost when I was just causing. I then proceeded to flash the acn91 map and continued to have high correction under low boost. The car is pulling fine and there are no misfires. Please help, I'm not sure what I should do next.

Thanks
