I only new to EFI live and I have a COS5 tune I'm working on and my issue is with cold enrichment.
When the car starts it sits at 14.2 AFR for about 10 seconds than slowly drifts to 16.5 sits there for about 1 Min than goes back to 14.4 until ECT gets to operating temp
I've tried to play with b3632, b3627, b3628 and b3650 but I can get rid of the lean condition
Engine is stock, otr and full exhaust
Don't know what else to try
Any suggestions?
