I was hoping that you would at least delay. We'll see what happens. I am positive that, at least from 19.01.01 on, that DSC and DTC do not fully disengage. I mentioned this matter earlier on the other thread--of course, before, getting 20+. Today, the shop foreman was very surprised when he found unexpectedly that DSC and DTS don't completely disengage with 20+ when he accelerated too quickly in M1 out of a turn. But, now if the problem is lack of complete disengagement, then the issue is a much more serious one. We shall see.

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.

Any idea if this impacts those of us with 6 Speed's?

The one run is faster to 10 MPH, but only on average. And, the difference is no wheel spin versus controlled wheel spin. Of course, I'd much rather have controlled fiercenes to 10 MPH, rather than full bore tameness, even if I always was behind .01 at 10 MPH. Some of my better runs had more wheel spin that I would have liked, but overall each of my better runs is way better than my new best (ugh!)

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.

I wish I could help, but I don't have a clue. I wouldn't do the update without a good reason. I did it for MP3--which, after the fact, is not enough of a reason unless learning saves the day.

znod

I have never seen these kind of complaints before, but, then, I haven't been around that long. Generally, people say good things about performance after updates, but I actually noticed the negative difference on the way home from the shop. Sometimes I wonder how objective the good things that I hear are; that's why I did not say anything negative until I had confirmed my "feelings" with the GT2. I definitely can feel .3 or .4 secs. difference--despite what some apparently think and say.

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...

Great details Znod. Keep us updated

im not going to comment on this... but its great you have taken the time to do this

znod

Lots of breaking loose by just applying the gas. I don't do brake torquing. But, incidentally, the shop foreman did it on my car. I asked if he thought that doing so can be a problem. He said, no, unless done too reptetitively.
