There are too many variables in R-T Analysis that are poorly defined and explained. It is not possible to give concise advice or make confident decisions with them while that state remains. I agree. I have no idea how the corner radius is calculated...which means I don't really know if my equation ...

Thanks for the help, but you seem to be missing the point of the question. I completely agree that this is not going to be accuracte data used to tune the car in the way of the actual accelerometer data. Hence why I have a DL-1 and not a lesser system. I think I'll just take simple answer as "N...

What accuracy is required? Very little. The vehicle relative accelerations are much more important as far as squeezing out extra time at the track, and that's being read at 100Hz by some pretty precise accelerometers. I'm simply interested in seeing approximately what affect the banking has on the ...

Perhaps you can derrive this from the GPS position and speed? Yes you can. GPS based data loggers without accelerometers already do this. (like MaxQData) I'm wondering if the DL-1 software has these equations built in or not. I shouldn't need to subtract out anything, because I really am looking fo...

Relative versus absolute lateral acceleration?

Hopefully I'm not completely missing a built-in variable somewhere, but is there a way to calculate absolute lateral acceleration? To clarify, the accelerometers on board the DL-1 move with the car and so always measure acceleration relative to the orientation of the car. Therefore, when you go arou...

The main thing is to use a strain gauge amplifier that will get the voltage to be logged into a range that can easily be read and resolved by the DL1 (ie volts (0-5 or 0-12) not millivolts. Thank you, that is helpful. Would you happen to have any recommendations for amplifiers people have been usin...

for anyone that was following this thread, the solution was that the DL1 had previously been reconfigured for maximum resolution on analogue inputs so the voltage scale was halved to obtain double the resolution for some strain guages. Does anyone here have experience using strain gauges with the D...
