$DA2 def: Accel Enrich vs. Differential TPS (Mult).when does

I have a question about this table.

Its set up as a 2 column. % TPS vs. % fuel adder.

Currently the values are pretty close to 0 for all % TPS.

Does this table only add fuel for a brief instant when you press the gas, or does it add fuel the entire time you are at that % TPS.

Im assuming it operates in both closed loop, as well as open loop.

The part that confuses me is the word 'differential' . What does this description mean.

Any help is appreciated!

used in closed and open loop.

it's for periods of rapid throttle movement and only takes effect for a very short amount of time.

differential is being used in place of "delta". ssentially how far has the TPS moved since the last time it was checked.

Thanks for the info.

This sounds like it could be a 'fun' table to apply fuel - for instant when you get into it.
