dashpot decay fn879

Unread postby neald » Wed Jan 09, 2019 8:46 pm

hello. im looking for a little guidance on this table. what do the values in the x and y columns mean. and what do they measure? are they time? air volume? i saw Deciphas writeup had a sample with these values:
2.00 0.0025
1.25 0.0800
0.50 0.0030
0.30 0.0007
0.00 0.0007
0.00 0.0007

Meanwhile mine looks like this:
2.300 0.1001
0.750 0.0181
0.500 0.0039
0.250 0.0010
0.000 0.0010
0.000 0.0010
granted mine needs alot of work as it hangs around 2000 rpm or so after i release the throttle. just want to understand how the function works so i can get mine where it needs to be. Thanks

I just changed all values in column 2 to .1000 and it decays much faster now. And doesn't overshoot idle. I still would like to know what each column in this function does.

x is dashpot lbs/min and y is the decay rate in lbs/min that it is reduced per loop

Found some threads here on the function. So being an automatic I'm guessing I don't need too much decay.
