well i have a 08 nytro on boost runs 16 17 on air fuel gauge at idle ad gets a little better at wot need an expert on apure logic box to help me thanks colin
It sounds like you need to add fuel pressure off the regulator first before you play with the pure logic box.. Ideal a/f rating at idle is 13-13.5 and WOT should be 12.2-12.7.. Do you have a fuel pressure gauge to know where you are at?
What are the factory CO's set at? Try using the green/blue setting to get more fuel by increasing the light value. You should be able to make it run really rich by increasing it all the way, then start backing it down from there.
