ECU God's, please lend assistance
Someone in the A4 forum was suggesting running 30# injectors on a 1.8T A4 without reprogramming the ECU.
I thought the ECU couldn't adjust for this kind of change.
If it does, how?

how much bigger is 30# injectors to stock?

but really, whats the point? you are not maxed out on your fuel injectors unless you get bigger turbo.

True. I'm curious if the fuel trim is used in both WOT and part throttle....
modes.
If the ECU is running consistently rich (or lean) at part throttle, it makes sense that it would also run rich (or lean) at WOT. So it might use the fuel trim for both modes, but only adjust it during part throttle. Of course, it might not....
