AFR Tables... Tuning and Closed Loop looky what i did!!!
So i think i found out a pretty slick way of getting my fueling tuned in nicely using megalogviewer and also having a great resolution afr table for closed loop operation. Take a look, what do u think?
Here is a snap shot of my afr table within my .msq. I have my car set to go into open loop at 120kpa. So I scaled my afr table to match and now have great resolution for cruising around town and on the highway.
Next i setup the default afr table within megalogviewer which also has one cell for every fuel cell so it tunes it in much better:
What do u guys think? Pretty cool huh?

Stupid question but what exactly is open loop vs. closed and what does switching to open loop mean/what would be the benefit of setting it higher than the normal value (53 kpa)?

I wrote this when I was quite drunk, but it is correct.
I'm drunk, so excuse the absurd pre-school style conversations.
open loop
ECU: Sup O2 sensor.
O2 sensor: Sup ECU. You're a little too lean.
ECU: No **** you O2 sensor.
closed loop
ECU: Sup O2 sensor.
O2 sensor: Sup ECU. You're a little too lean.
ECU: OK, we'll add some fuel to that ****.
O2 sensor. C00l.

Unless you mean a NB switch point in which you need to update to the latest code as the devs forgot to include the code in the .ini which let's you see the dialogue box...
Don't think 3.0.3xxx has been done yet but 2.1.0xxx was put on the forum today
