Title: Confusion on fuel table function
Post by: ccsturgi on March 02, 2015, 05:57:26 AM

This one may need to be filed under the programing theory section, but I will ask anyway.

Part throttle fuel table has rpm scale on the left pulse length based load scale on top. The values in the table adjust the Afr by adjusting g the fuel. The only way to adjust fuel is to adjust pulse length. So, I don't understand how pulse length can be used to scale a table that adjusts pulse length. Seems like a loop to me. Can anyone explain?

The fuel maps are correction values. They can be displayed in a number of real world values, but to keep it simple, we leave them as a raw number where up = more fuel and down = less fuel.

Load it calculated by an equation, not a singular measurable event. Injection ms represents the closest real world thing you can measure and the more load on the engine, the higher up the "load" scale you will be at the given RPM. The number in that cell is used to adjust fuel from the theoretically calculated amount into the real world needed amount.
