Hi Fellas my first post on here and hoping this isn't a question that has already been asked, so forgive me if it has.
When tuning the 4d table theoretically should there ever be any alterations to the table below 100kpa?
G'day Mark
If you havent watched it already, this will be a great webinar to have a look at: https://www.hpacademy.com/previous-webinars/163-tps-map-tuning-for-turbo-and-itb-alpha-n/
The way the Link ECU's do alpha-n (TPS based load) tuning for a forced induction engine involves a background equation which compensates for changes in manifold pressure when there is no change in throttle position. You define the lambda values you'd like the engine to run as usual in the lambda target table, which still has a load axis of manifold pressure. This is what allows you to have different lambda values at different manifold pressures, for the same throttle angle.
Hope that helps? Cheers.
This is pretty much what I need to find out wether or not there should be any adjustments in vacuum
