Wondering if anyone is running NT-01's on a 911 with an Aim system (SoloDL/SCHD). I'm seeing average lateral acceleration of 1.0g around the corners with peaks at +/- 1.2. The reason I ask regarding an AIM system is I want to compare same sensing approach (GPS) with the same data averaging.

Here's a screenshot of a recent session at Palmer.

Did you calibrate the electromechanical accelerometers on the mounted-in-place Solo DL, on level ground?

Nope; but I just looked over that data (accelerometer lateral-a) and it looks similar with a 3.3g offset which I removed from the data. Here's a graph of both (with G-sum for reference as well which is based on GPS acc data).

I'll have a look at my Palmer data tomorrow. I can send you the NT01 data tomorrow of you want.

I seem to recall I see about 1.3 before break away on a non or very slightly banked corner.

That would be great (although entirely different car)!

It varies with the amount of banking on the track. In slightly banked corners, a steady 1.0G to 1.1G is typical with NT01's on my car. I'm not pushing the car to the point of sliding a lot, especially at Palmer which can be very unforgiving. On corners with a lot of banking, I see short peaks around 1.4G to 1.5G--for example turn 9 at Palmer or turn 6 (the "bowl") at NHMS. However, these short peaks may just be "noise" in the data, although I see it recur consistently on the same corners. I'm sure faster drivers will see slightly higher readings than I'm getting.
