Accelerometer function for Atap

[tici]

Is there a way to measure acceleration wit Autotap?
I don't care about HP, I just want to see if a mod had a result or not.
I could take the times from 0 to 100 mph and make some calculations, but I don't know if the program records data fast enough (I have the Palm version).

Thanks - Stefano

i dont believe so, not even for efi either. you'll want gtech and those type of gizmos if you want that kind of data.

-If- your logger runs on consistent time-ticks then you
could use Excel to derive this from the VSS or speedo.
Just (MPH2-MPH1)*(5280/3600)/0.1 would give you a pretty
close ft/sec2 value although it will be kinda granular.
The /0.1 being for if you are logging at 10 frames/sec.

Do this for the 2nd & first speedo data cells, and then
copy&paste all the way down and there's your acceleration
vector. Divide by another 32 for Gs. The VSS might be a
better-resolution primary value for this but I don't know
its format / scaling.

I can also log time and speed, make a nice curve and calculate the acceleration.
I saw some programs on the web that calculate power depending on car weight and time from 0 - 60 mph...

Like in the school, many many years ago...;)
