Long term trim, aggregate or by cell?
Posted: Fri Jan 29, 2021 6:00 pm
We are presented with a single value for long term trim from the ecu. I don’t know if this is an aggregate across all cells and circumstances or if it’s actually a per-cell value. Based on what I see it looks like an aggregate, but wanted to verify that?
Question part 2: even if the value we see is an aggregate do you know if the ecu internally works with that number as an aggregate or is the ecu actually maintaining and using a different long term trim per site in the map and just outputting a single aggregate for simplicity?
