Hi, trying to help my friend get his 2007 z06 to pass emissions, mild mods, wcch heads, katech 110 cam, haltech cold air intake but no headers or other major mods. Tried like crazy to get the evap to set, ran the sequence several times this fall, last time made extra sure to get the right time off between starts, no luck. Based on other posts it sounds like others have had luck using HP tuners to set the evap test complete by turning off fuel trouble codes. Still no luck. I think catalyst test is also not setting which is odd as the car does not have headers and all 4 o2's are still there. Anyway, could someone look at the attached before and after tunes and let me know what we might be missing?
