OVT vF Map Edit - Air Load Control (ALC)

Interesting. Thanks for weighing in.

 

Yes. @OVTune never edited most of the stuff that we are doing. The big deal is if it matches the 04B04 / 04B14 stuff. It sort of looks like it. There are three more maps to look at. The other Lambda here and Expected AirFlow.

 

Thanks, @OVTune !

 

Ok, here are all 4 maps for 04B90


Control AirFlow .821 lambda


Control AirFlow .999 lambda




Expected airflow .821 lambda





Expected airflow .999 lambda

 

Thanks! I'll do a check later unless someone beats me to it.

 

From memory, they look pretty identical to 04C30. I could pull them all as well to be sure but I doubt they'd be much different if at all.

 

I was just curious if they were different from the factory on model years. Some people say the 20 and 21 run better than previous, just compare and contrast you know

 

I drove an 04B91 MT. It felt just like 04B14.

 

I can't speak to the MT but that is the case with the AT.

I feel the biggest difference in the 'driveability' issues is the behaviour of the transmission and shifting which is not really a factor in the MT as that's user-controlled

 

Hello, Folks.

I updated the ALC map names to reflect the current vF version. I also added a good quote from @OVTune to help understand the map editing.

 

So basically just edit the Ignition and Throttle efficiency tables and leave the third (engine mapped expected) alone? Not going to lie, that third table is a pretty ugly looking, haha.

 

I have yet to touch that third map and no one else have ventured there either, AFAIK. Agreed that it doesn't look good.

 

Adding 04B42 Stock ALC Maps for @92ehatch . Zero difference from 04B04 / 04B14 Stock or unedited OVT. I checked them in Excel just to be sure.
