    Timing calculator uses duration and fuel pressure to determine how long it will take to inject the fuel at a given rpm. The percentage is used to determine how much of the fuel is injected before TDC.

    A good starter tune is to make sure you're commanding full fueling from the main injection duration table. Look at the x and y axis for the table and go to the tables they reference. Bump the upper half or so of main injection by 20%. Go to the timing table and use the calculator to set timing 50% before TDC. If you have the emissions removed, go ahead and turn off the post injection by zeroing those tables.
