(I just can't do 3.; it seems to mix up the commands and resets Target Speed, but others have said they can/do and it works somehow. This is one place where "compromise" from the ideal may be needed.)

nonseq, I wonder if there might be a different response depending upon the DME s/w version last installed? My 2003 was last updated as part of the US emmissions recall. I have not wanted any update since then. This was done back on 12 Nov 04. The work order only says "REPROGRAM DME W/CD 38.0 OR HIGHER" but it does not say which version was actually installed. I still get very satisfactory results using the detent for launch, then going to WOT at or before redline.

This is a very proper subject for this Driving Technique Thread.

Launch is a significant one weak point in the MINI CVT drivetrain for many drivers. The expectations established for the marketplace by a torque converter-equipped "automatic" or traditionally-clutched manual are not met by the ZF VT1F CVT. Our gearbox excels at what it was designed to do, better than the alternatives, but this is one of the compromise areas.

We should be able to mitigate this by driving the machine properly. There is practical everyday experience like that hinted here from valnmike, and some direction from ZF Getrieb.

Let's explore specific ideas, maybe measure the differences, and come up with a recommendation!

valnmike,
Will you outline the "best" way to launch and accelerate for maximum effect to get us restarted?

I will try to put this together, but I've been pretty busy lately. I also have this to do over the next two Saturdays http://www.northamericanmotoring.com...d.php?p=658419

I will make the attempt though, if ya'all can be patient with me.
