Need a Good Timing Calculator

Looking for a timing calculator for the 6.7. I downloaded one and tried using it and it came up with some crazy numbers like 75 degrees at idle and such. ive tried changing axis values and converting data from unit to unit and still crazy output. If anyone can point me to a good timing calculator I'd really appreciate it. Thanks

Did you ever find one? I see that the efi live has a built in calc
