Need Approximate Coast Down Curve for LS1 F-body Speed -v- time during a neutral coast down is what I'm after.
Any car would do - I'm only after approximate answers.
Thanks

What software are you using? There are stock tunes available here in the HPTuners .bin repository and there are EFILive .tun's available @ http://www.stealthv.com/tunes.htm .

I've got a 1/4 mile run where I logged data with autotap.
Granny shifting my M6, I was actually coasting 1.5 seconds during the 13.6/107 mph run.
I'm trying to calculate the MPH car is capable of if not limited by M6.
First correction is taking MPH from data, 1.5 seconds after traps. (MPH went from 107.2 to 109.8)
Second correction is adding MPH lost from coasting during those 1.5 seconds. There was about .6 sec from 1-2 and .9 sec frorm 3-4. Maybe this will be worth .5-1.0 more mph?
If I could find any coast down curve and a drag coefficient, I would back out something that would be close enough.
What is interesting, is that this run was on a hot day with car very pingy. On a cold day, it was "keeping up" with a solid 115 mph Corvette. Looks like the numbers might confirm that.
