I am in a sharing mood:
These are for 53040010, i'll update this post with any other ROMID's I (or you) do

low pulse adder is on 100% of the time, ie if you IPW would have been 1.040ms, then the final IPW would be 1.096.
You can see this would really only have an affect on larger injectors
the enrichment/enleanment maps are purely based on the rising or falling of load. all the multi's are multiplier together and then the load delta is also factored in. These maps are injector scaled, meaning that you shouldn't need to mess with them too much for non-factory injectors.

Cool - I'll have to look at these more later but I wonder if some of the decel stuff is (or is in the same group) as the tables that control how and when fuel finally shuts off when you are in gear and off throttle. I've always wondered what was actually going on there!

yeh - never found anything
i dont think there is a map to control timing per rpm.. so i think the ecu just picks on "time" for all rpm;s.. which is a bit crap

Has anybody figured out how to disable the decel ipw enleanment all the way yet? The values are all displayed in unknown units, I just cannot seem to get it to not pull fuel when I let off the pedal.
