ECMlink High air fuel ratio at idle (dsmlink log)

[90EclipsePos]

Was wondering if some of you guys could help me with my dsmlink settings. I feel like I have most of the settings dialed in ok but not sure where else to make adjustments. My main issue is running really high air fuel ratio at idle it will normally run around 16:1 to 17:1 after warmed up according to my wideband o2. Cold it likes to die and is running above 22:1. I feel my fuel calculations are off because the combined fuel trim is -15% but i'm having a hard time dialing them in. Another question I have is with dsmlink when setting a higher idle do you still have to set timing to 5 deg or does it change when running a higher idle? Also with larger cams is the air flow per rev still around 25?

The car is a 91 gsx 5 speed converted from auto, 1000cc injectors, 340lph fuel pump rewired, 2g maf, and 272-264 cam combination dsmlink v3 ECU was just wen thru this year. Since I purchased this thing I have replaced a lot of faulty parts and still might have missed some so if you guys have any ideas what else to check let me know.
