fuel tables are arbitrary linear fuel values

What are the fuel units in ROM Editor not milliseconds?

Injector duration varies with a number of different conditions (water temperature, air temperature etc) and is not linear. E.g. an injector duration of 4ms will not deliver twice the fuel of an injector duration of 2ms (it will be almost three times the fuel). The numbers in the fuel tables are arbitrary linear fuel values. A fuel value of 500 will deliver twice the fuel of a value of 250. You can see the approximate injector duration on the 2d and 3d graph views by selecting Show Injector Duration.
