Hi Znod
I have been studying your post#66 and have come up with the following thoughts:
1-Time to speed & time to distance are similar but not the same.It appears your 0-10,20,and 30 times with 20.01 are very close to the times you got with 19.01.Other than your 1/8 times I don't see other time to distance figures for 20.01.I am curious what your 60' times are with 20.01.I have had some poor 60' times due to wheelspin but still registered decent 0-60 times.

3-However the the period of time the trans takes to start & complete the shift is relevent.For example if the shift times for 19.01 took .3 sec and now with 20.01 the shift time is .5 sec,the .2 sec diff is lost time and cannot be made up.It is also possible that 20.01 more agressivley reduces torque during the shift which would temporarily reduce your acceleration rate.

In summary my best guess is that the quickness & firmness of the shifts with 20.01 are not as agressive as with 19.01.Note that other posters are reporting "smoother" shifts.Smoother is not conducive to faster times.
I don't know if there is a learning curve with the new software since we did no testing after previous updates.

You are correct,If the shift occurs say between 59 & 61 it would affect both segements(50-60,60-70),but I think you had a much larger discrepancy between 50 & 60 indicating maybe the shift was either complete or almost complete by 60.
My experience with some of the muscle cars I owned didn't show a noticeable increase in time even if I shifted 500 RPM lower.The engines in those days had very narrow torque peaks.Of course there were no engine management systems to get in the way.
On your horsepower issue you must remember that the GT2 derives horsepower from a number of inputs.It is strictly a calculation.Your time to speed is the only the only one that is changing in this equation,as your time increases your horsepower readings will decrease.It can't account for faulty shifts but just see's a slower time therfore you must be developing less horsepower.

WAO and this tread keeps going.. well got CIP 20.0xx and all I can say my Idrive boots fast the car feels smoother and actually quicker (butt dyno) ...so unless it only applied to 545s Im very content with the upgrade..something that caused me a bit of concern is that they could not program the CCC-a unit the first time but they got it.. so far so good

I am in the process of making the"supreme sacrifice" Znod.My 545 is being updated to 20.01 as I write.It's a long story but a computer module has been replaced to repair my adaptive headlights and requires reprogramming.After much discussion the dealer insists that they must use the latest CIP version per BMW.I decide not to continue to fight and will look at it as a way to prove or disprove if 20.01 is the reason for your lower performance problems.No one else with 20.01 has GT2 data except you.I will do some runs as soon as weather conditions improve(50 deg or above)and compare data to my runs with 17.03 software.
I refuse to believe this is a permenant situation and it will be rectified in due time.

Did you see that I suggested sending me another email possiblity via PM? Apparently, I can't attach the files here.

I'm getting another one of those headaches...
I hope your headache never developed or, if it did, that it went away soon. I would like to return to a status of neither of us being mad at the other, etc. I definitely am not mad at you.
I have apologized for being sarcastic. I did it with full awareness and take full responsibility. I worded my original repy to you too harshly and used too many words. One of my main points, which didn't seem to come through clearly, is that it appears to me that you are singling me out for a few transgressions and not saying the same sorts of things to others. So, I would appreciate it if you would refrain form doing so if that is what is occurring. Either way, as requested, if you have comments on what or where I post, then I would appreciate it if you would PM me rather than making your comments public. I think that using this procedure is best for avoiding misunderstandings and public squabbling regardless of the identity of the perceived offender. Thanks.
Best,
Znod

"I don't know if it's only me but I'd like to find out if others are noticing what I've noticed on my E90 after getting the CIP 20 software upgrade on my car.
I've noticed that now when step on it the car is less aggressive . At When the pedal is to the metal, and shifting between 2nd and 3rd and 3rd and 4th I've noticed that the pull is not the same as before I took the car in for service. Does anyone have any *real and reasonable* explanation for this? Is it just me?"
My appointment is set for Tue. morn. at 8:00. Thanks for your advice again.

Great DJ. I hope you will start a "Killed" thread in the "The Competition" section for fun and tell your story; it's a good one.
Or start a BEEN KILLED thread LOL SL65 AMG! I WANT THAT CAR!
