Now you have me really worried.There is no way I update to 20.01 until I am positve it will not affect performance.I can't believe a company that has built its reputation on performance would deliberatley detune our 545's.I thought maybe Znods numbers were just a fluke and would return to expected times soon,but with Lomag & others noticing a decrease in performance with 20.01 I believe it might be intentional change in the software.Possibly Znod is correct in that the DTC/DTS is not fully disengaged which would kill the low speed performance.I am anxious to here what the engineer has to say I am sure Znod will keep us meticulously informed.
I am also very impressed with your SA Znod.I would not have the confidence to approach my SA with my performance numbers.I just don't get the feeling my Dealer would look kindly on me showing him how many 0-80 runs I have made,and me complaining to him that I can't smoke the tires like I did with earlier software updates.

Note that my numbers might imply worse Step shiting from 1st to 2nd and better Step shifting from 2nd to 3rd. Also, note that the whole "loss" appears to have occurred by 60 MPH, but there is no way, at this point, to know what might happen from 80 MPH up (i.e., I have very limited data from 80 MPH up). I do notice a serious difference in the feeling of power right before the 1st to 2nd shift and, of course, off the line my car now is relatively dead.

Znod I just noticed that your acceleration rate from 0-10 with 20.01 is actually faster than before your update.This might mean that the DTC/DTS thing may not be the answer.All other acceleration rates are faster before 20.01.

I see what you mean,it definitley looks like you are down on power throughout the runs.The acceleration rates tell the story.the are all slower after 10 mph with 20.01.Very disapponting I hope relearning is the answer.I just don't remember complaints with previous updates about performance.I do remeber shift complaints after updates.Maybe if there were more GT2 users over the past year we could have verified that the actual acceleration was slower after updates until the computer relearned its settings.

Znod... when you said you can brake the tires loose from a standstill before were you able to do that just by mashing on the gas or did you had to brake torque the car? Cuz on the old E39 540 that I've driven before I tried my hardest applying the gas as fast as i can and I was never able to break the rears loose without brake torquing...
