Acceleration enrichment

I understand the concept of acceleration enrichment (sorting out transient lean spots when you stand on the accelerator), but I'm unsure how this translates into setting the parameters. Right now it's pretty good, but I'm only guessing at them and I know it's not quite right.

VEMS measures delta TPS (ie speed of accelerator position change):

I can only tune by looking at logs (the added amount shows which bin the TPS-delta was in). The delay in WBO2 reading makes it a bit hard: but when you know which bin to tweak, you feel when it's right.

Thanks Marcell - just what I needed to know.

BTW - I have got a good idea of the "transit time" for my engine, and I have a short bit of code that works out the "transit time" and time aligns the WBO2 readings in a datalog for me.
