The 0-60 time I based on the datalogs and rpm at which the car should of been going 60mph(which I forgot to mention, the 0-60 times were above 6,000 feet elevation). I took some account for converter slip, but that shouldn't dramatically change the time, maybe a tenth of a second or so giving the rate of rpm climb in 2nd gear.
This weekend I'm going to see about fitting one of the wheels with a vehicle speed sensor. From that I should be able to accurately determine 0-60 and possibly even 1/8 and 1/4 mile times as there are distance calculators in the MegaSquirt software and datalogging software. Getting the VSS hooked up on my Skylark I've just started to delve into those functions of MegaSquirt. There are built in formula's to determine wind and rolling resistance as well as HP and TQ (as well as tripometer and mpg instant and average calculations), but again, I haven't spent the time yet to see how those features are set up and function.
