Last time I dynoed my car we were unable to keep the car in 3rd for the entire pull.....even when in manual mode. The car would continually downshift into 2nd if you weren't high enough into the RPM's, and then back into 3rd, then 4th......is there anyway to keep this thing in 3rd?? I've got the W220 S65, FWIW.

I believe you should be in 4th for a dyno.

Im assuming you have it in dyno mode?

3rd for a stock ECU because of the 155 speed limiter

and yes, in dyno mode.
