Interested to start a discussion on the various ACE enrichments and/or combinations of enrichments others have used on boosted applications.
More specifically on limiting momentary enleanment during shifts on WOT runs.
Discuss...

I dunno - I've kind of grown to like the fireball on upshift thing...
Going lean on upshift can often be caused by either decel fuel cut, or the min injector on-time being too small - what do you have those set to? _________________

| You might also do a log a examine the map sensor response. I have seen poorly plumbed sensors that respond slow and so the computer hasen't gotten a command to move the the correct cell in time.

Ah... I did not think of decel being involved. My current settings are below.
The engine idles around 78kPa.
Minimum On-time is 1ms
PW at idle is 1- 1.1ms. (720cc injectors)
DCCL3 = 70kPa
DCCL0 = 800RPM
DCCL1 = 800RPM
DCCL3 = 3 volts/sec
DCCL4 = 5%
Looking at my data logs the MAP seems to respond directly to TPS inputs. I am not sure what to look for to determine sensor signal lag.

Exactly like that.
...or like this

okay, actually that was from the rev limit fuel cut. _________________
