I was looking at a few files that I got from a friend to start my car a while back.One is for pump gas and one is for race gas.

I did this because I was trying to see what difference there was between them and my original startup file,because his file will start my car and mine won't.

I did notice one main difference.The fuel energy constant was different on the race gas files. On the pump gas file it is set at 1.00,and on the race gas file it is set at 1.992.

Why is this? Is it supposed to be this way?

The reason I ask is because the XFI help manual shows no such fuel constant for race fuel. There is just a gasoline constant of 1.00 on their chart.

Thanks for any help understanding this.
