The calculated graph from efilive is smooth on the dyno, but when run on the street is very erratic... Get me now? .

The way I see it is, since there are lot less variables on the dyno its easier to apply the force to the drum than to the street.. wheelspin? different waves of air?? maybe if instead of logging 24PIDs one logs 3 or 4 would get more frames per second and provide a much much smoother curve.

With the AT123 V2 I am getting 9.4 frames per second... I got with more PIDs 10frames/s out of an OBDI!!!! So.. I dont understand.
