#3358, "Target A/F Ratios"
Aug-15-07 09:22 AM by Aggression



          

What do you guys generally see as the best A/F ratios throughout your whole kpa range?

Reason I am asking is I get inconsistant results.

I've tried 13.5 from 40kpa thru 100kpa and then 11.5 for anything above 100kpa. Then I've tried stagering it.

So what A/F ratios do you find to work best from you through your whole KPA Range of say 40 to 250 or what ever your range is set from.

I just found this in wicked's post about his MS install.




What does everyone else's look like?

Thanks!

Yeah, I could really use some help getting mine running for the shoout out. I havent been successful at autotune or the VE analyer in megalogviewer. Every time I use a program to change my VE table to meet the target A/F it screws it up and makes it really rich again. I've made sure that it was using the correct a/f targets as well.

2 days to get it figured out.

I started setting the filter to hone in on a desired area of the map to tune, then I try to keep the pointer with in the designated areas to get as many hits as possible. Seems to work well so far!
