Delete all rows except your 3rd or 4th gear pull so it is good data and save the file. You can then upload it to the Virtual Dyno software. http://www.virtualdyno.net/

It is also very important that you have your car weight correct and you also need to input the size of your tires.

Awesome stuff, thanks!
