Sounds perfect

Any one have the motion ratio for a 997 cup or maybe it's different on 2013 gt3 R geometry ? It should be little different I think mostly in the rear

I have uppgraded to a adl3 with 250mb memory 50 I/O and pro logging so i have it all for maximum logging

Yes please email shock spread sheath

Motion ratios will be easy once you zero the shocks. Raise the car so that the tire lowers 1" relative to fender lip and see what the pot distance is. Shock movement divided by wheel movement will be motion ratio. Different front to rear.

Thanks

Then I do a math channel for wheel motion ?

You could do a math channel or you could calibrate the potentiometers to show wheel movement rather than shock movement. I don't know the ADL 3, but with AIM you can pick the sensor to be a mid zero type and you do a manual calibration by moving the wheel and define the distance moved. I'll look at the ADL 3 config and see if I can find how to do it

Wouldnt it be best to have both..?

Or is the wheel motion the most important, i think the math channel will be done in the i2

The shock movement is needed for analysis, so it would be best to do a math in I2 Pro to show wheel movement.

Here is a link to my website where I have an article that I found about shock speed analysis. You can download it from here http://austinmotorsportsllc.com/docu...ce-information

I have now done a math channel and it works fine so now i can se both the shock movment and the wheel movment..

When i have had my first track day i can post the loggs so we can tune the suspention here on Rennlist..

Also

Wouldnt the wheel movment and the shock springs give me DF level also or do i need more info for that..?

Or do i need the Hz for this..?

I am intersted in the spreadsheet . I just installed shock pots in our 2010 R in New Zealand. I feel with all this new data I am going to have to play with, my uni degree is going to get less attention

What do you mean by DF Level

Yes, the potentiometer movement and the spring rate will allow you to determine downforce (approximate), however, the track needs to be very smooth or the shock movement will be too "noisy" to get good numbers. If you are doing that test, I'd re-zero the shocks on level ground just before the run, to get a good reference.
