Cold Start Up Idle Surge
I am posting a scan of my cold start up and a tune file. When I start my car, the idle surges and will not settle to one speed. I need help. Can someone smarter than me take a close look at my tune and see what is wrong. The rest of my tune is great---it locks at 0 LTFT's at full throttle with no KR---very satisfied with that. But my cold start up is embarrassing. It does it when completely warmed up too, but I didn't post that scan. I need the cold start up fixed first. Somebody please help me!

hi, I am a beginner but I think O/L AFR or START UP AFR CORRECTION can help,because vs T?C. before check if ECT is fine.
