Crappy Comcast cable acting up, will call it a night. Brian is going to get data for other gears to add to chart. Data file: time (sec),engine speed (rpm), car speed (mph), car speed (ft/sec), car accel (ft/sec^2)

2280rpm to 6680rpm in 35.2 seconds. :-( Is that right?

 

I think you missd a data point in there somewhere. no really, nice work.

 

with max torque around 3000 rpm at almost 2/10 g?

Could you run in the other gears? Shift points should be where accel's cross (descending in lower gear, rising in upper gear).
