zero out the MAF table.
I agree Ed, and that is how I have been running till lately. I like how running just on the VE table seems crisper, maybe it's just my imagination.
I'm running '02 1bar SD tune. The table I mention seems to make you chase the tune. The numbers on the bias table, higher number pulls fuel out to go leaner. As for the filter, the higher the number,...
from my experiance, suring is from a rich condition
tune Cylinder Charge Temp.

Why do I see all these guys selling "mail order tunes" telling everyone to run such a cold engine?
I see lots of guys using 160* thermostat with engine temps running around 180*. I changed to an 180* thermostat with engine temps running around 195* now and I have no dyno to back it up but it seems...
do a search here for "hybrid" tune
a wideband tells you what your air/fuel mixture is so how are you going to know where you are now and if you do make improvements how will you know? sounds like you are shooting in the dark :shrug:
