Znod,
I have had the battery disconnected a number of times withn no change on re-connection.
How are you going about measuring your 0 to 60 runs?

Hi Friends:
I have several new observations about 20.01.00. First, my power and times, per my GT2 g-meter, are worse after updating to 20.01.00. I did 4 or 5 zero to sixties today and got no time below 5.5 sec. My car had been doing 5.07's to 5.20's very regularly. Without doing calculations, I am sure that I have lost about .4 sec. to 60 on average. The HP power values given are somewhat consistently lower. Please note that there was no significant lack of test-condition comparability between today's tests and my earlier ones.
In this regard, I have been happy to have, but have been noting that excessive wheel spin was killing some of my times prior to 20.01.00. Today, I could get no wheel spin at all. I did one run with DTC on and got 5.70. As always, not turning both DSC and DTC off is an HP killer. I am not sure what is going on, but I suspect that the problem is that turning both off does not work any more. Alternatively, my engine now is detuned. I mention another possibility below.
My situation is reminiscent of when I first started testing. My times were in about the same range. But, over time, they got significantly better, and I couldn't account for the betterness by improved techniques. I learned very quickly that my Steptronic 545i is point and shoot in DS unless there is a need to control wheel spin or one wants to brake torque--which I don't do. I speculated that my improved results were the result of computer adaptation to driving style, but have never been able to confirm that the 5-Series computers learn in this way--as does my Z06. I quess my current situation will provide an opportunity to gain evidence on whether the 545i computer does learn driving style.
With respect to the Steptronic, while I am not sure that the Step shifts better, it does seem to shift a bit later--which should be good. If not, then the "laterness" might open up the option of shifting manually to improve times. Finally, I have discovered that the 545i apparently does have an actual rev limiter. I can't do what I will describe at full trottle--because the Step then shifts automatically no matter what I do. But, at least when I "hold" the tranny in first or second (didn't try in other gears) I can acutally go beyond red line and activate a rev limiter. If you don't know, you can hold your car in any gear "longer than usual" by holding the lever forward. I don't think I could go beyond red line before 20.01.00, but am not completely sure. How about someone giving this techinique a try in their non-20.01.00 545i (B32???).
Does anyone know if we ever are allowed to go backwards on updates? To heck with MP3 if I could get my .4 secs. back. And, does anyone know if dealers trash old software updates when they get new ones?
My Dinan CAI install is scheduled for Tuesday. But, if my car doesn't start learning soon, then I see no reason to follow through on the install. Why mod a slow car? But, of course, my car starts learning, a fix comes out, or I am allowed to go back to 19.01.01, then I can always have the CAI installed later.

Does anyone know if this 20.01.00 is available in the UK yet

Znod, i think you are implying the wrong thing here. Your timings might be becuase
of a different upshifting pattern by the gearbox, but they have nothing do with the engine
output! AFAIK cip 20+ has no new engine maps, and do not forgot that even if the engine
was "re-tuned" for a better mpg , then this would pretty much not affect its behaviour
in DS mode

Finally, 20.01.00 does fiddle with the engines somewhat (as a carryover from 20.00.00), but, as you suggest, this minor fiddling probably is not at the root of my problem (see below). My greatest suspicions are that I can no longer turn both DSC and DTC off or "learning" is needed. If either is the root of my problem, then either would explain the lost performance and its highly obvious observational effect--i.e., I can't get any wheel spin at all, and I used to have much wheel spin with both DSC and DTC off--which was a good thing.

SUBJECT
MODEL
E60, E61 (5 Series)
E63, E64 (6 Series)
SITUATION
Customer may complain of the following:
The following software errors were corrected with the release of Progman 20.01.00 (Target data Status E060-05-12-510).
While driving, the SMG control module switches to emergency program. SMG Fault Code 5101 (Hex) "Analyze hydraulic sensor" is stored. (E60 M5 only) Refer to SI B23 01 06.
Check Engine Light is on, DME FC "2F4F vehicle speed plausibility" (N62TU only).
The following software errors were corrected with the release of Progman 20.00.00 (Target data Status E060-05-12-500).
Poor Idle quality after a cold start. N62TU engine.
Engine juddering/idle speed surging when it is cold. N52 engine.
Engine pinging under light load. N62TU engine.
After programming the CID (Central Information Display) using Progman V19.x, the CID is blank and fault "A469 Internal Electronics Failure" is stored. Progman 20.00.00 prevents this programming failure. If the fault already exists the CID needs to be replaced.
The following software errors were corrected with the release of CIP 19.02.03 (Target data Status E060-05-09-535).
No software corrections included in this version of CIP"

Znod,
I just picked up my car and they did the 20.0.1 update. Immediately I noticed that the car feels very heavy. The steering is much heavier (which is nice), but the car feels like it's lumbering along, not nearly as nimble/quick as it used to feel. It actually reminds me of my wife's 2002 540 now.
I am really not pleased with the heavy feel of the car.
Does yours feel heavier to you?

Has the car improved yet after these few days Znod? I assume you have been driving it harder to make it learn.

Could this be the updated from BMW since the cars performed very bad in handling situations in Swedish carmagazine.
