maf scaling and ecu definitions
I need to rescale my maf.
Using a lm-1 wbo2 and and will be using enginunity for the changes.
USDM 2005 sti
Im running rich right now.
Redline in 4th 10.1
Im looking to lean out
So when rescaling will i need to change anything else (any other tables) other than my maf sensor scaling table?
Also there is a new ecu definition on scoobypedia for my year and model.
Should i use that for my adjustments and then flash that to my ecu?
Or use the copy taken from my ecu?
What is the difference?
This is what i pulled off my ecu---A2BJB10J,AJ930
This is (?new?) one from scoobypedia--- A2BJB11J.AJ931

13.9-14.2 at idle suggests you're not in closed loop. I'm curious why you're messing with the MAF and not a fueling table. How do you decide to do one or the other? I was under the impression you only had to jerk with the MAF when something changed with the MAF like a different intake.
With my WRX, I installed the newest stock subaru rom and I'm been modding with it as a baseline. I didn't see any difference in the tables though I didn't check them all.

Might want to look at the Open loop fueling delay tables as well. I know for 02-03 you can zero the one table we have which can make OL/CL switching alot faster, but for the 05 I'm not sure.
I know there are long posts about all these topics on the Enginuity forums. Might want to do a few searches over there. I'll give it a look myself.
