Hi all,

I finally got my Road Dyno. I must say it is very easy to hook up and the software is written very well. Excellent user interface and easy to understand and use.

I am glad I got this instead of the G-Tech. Here is the link if you are interested in reading about it:

Here are the results for my 1992 400e. The data has been corrected for engine rating with a 20% driveline loss. Of course this is my best run. Interesting that on all of my runs, there is a dip in the torque output around 4k to 4.3k RPM.

All of the runs were done in the late afternoon, so the temp was high here in Raleigh. I'll see if a morning run gets better results.

Each run was done on the same flat road in the same direction. My best 0-60 was 6.3 seconds. Pretty cool what the data will tell you.
