Not sure if this is the right place to post this, some may already have been aware but in Techstream there are 4 learning ranges (idle rpm, low rpm, middle rpm and high rpm) for each injector sets. With OBD Fusion and the extended PIDs you can see these values.
Some have hypothesized previously that these are the learning ranges and I was trying to find a method to know if the trims have been fully learnt. I cleared CELs to force the trim to reset, and went on a quick 15min drive to get some food.
When the clear CEL was done the learning values were zero, and during the drive the values slowly picked up. This indicates some form of trim learning has been done but I've no idea whether if it's completed.
Top row are port injectors, and bottom rows are DI injectors. Idle, low, middle and high rpm go from left to right.
