But anyway, spec for a 1985 300D is right around 15 seconds, so performance sounds about right.

My son was only visiting with his iPod, so I no longer have access to it. Probably a good thing for my cars! I did allow for passengers and fuel in weight.
I obtained BHP figures on several occasions that seemed wrong. I think there is some learning on how to set the Dynolicious software up and how to drive the car when using it. Not sure what the wheelspin and squat on my SL does, but at times I got believable results and at other times, ones that were completely wrong. The latter ones were more than likely due to slight movement of the iPod during initial take-off.
By the way, where did you find the transmission loss info? I couldn't find 0fficial MB figures anywhere. I did see numbers quoted from 15 to 40%, so didn't really know what to believe.
