MSII v3 board, 2.886 code.
I've got my car running, so now it's time to make some test runs and datalogs.
But then...? I'm unsure about the afr table which MS generated for me, since I'm running ITB's, so I don't really have target values for my AFR table.
Have read the manual several times and tried to search these forums but it didn't help.
What's the best way to go here?
Set the whole AFR table to 14.7 AFR and let autotune or megalogviewer adapt my current VE table? After that try to figure out where my load/cruise areas are? If I know these areas, I still don't know which AFR is the best...(yeah I know load = rich, about 13 afr and cruise= lean, 16 afr) what's the way to figure the exact values out?
Could be a real stupid question, but after all the AFR table is in almost all cases the target and I can't find much info about this essential thing.

configuring an AFR table?
Ignorance is bliss...
Re: configuring an AFR table?
Thanks lance! But is there any way I easily can figure out where those areas are in my specific case?
For instance:
I'm idling at 55kpa and can't get it much lower. Throttlebodies are the cause probably. Everything below 50kpa could be deceleration that way.
Idle would correspond with the AFR table you linked to, but when I have 20% tps, my MAP is quite fast at 100kpa... so it's far from WOT, but in the WOT area. Could mean MS never can distinct my WOT and non-WOT areas... in that case I'd have to ditch speed density and go alphaN

Re: configuring an AFR table?
thanks again, that gives me (much needed) confidence to continue.
Modified my AFR table a bit, partly guessing where my areas are. Ran analyser from megalogviewer over it, made some big changes to my VE table, so I'll see how it works out.
After some datalogs I should see what my cruise areas are... probably should make a inboard video and play that simultaniously with my datalog to see what I'm doing.
