Turbo tuning for the first time
I finally got my turbo kit built and installed and am turbo tuning for the first time. I upgraded to cos3 and installed a 3 Bar map sensor. I followed the Auto VE tutorial however it feels like after about 10 to 15 min the car gets back into closed loop. After I get up to temp and start to drive the tune feels pretty good and is very rich as expected. I run 11:1 and 12:1 most of the time but after about 15 min or so it starts to settle in at 14.5:1 and seems to try and hold that all over the place. Can someone look at the attached tune to see if I am in open loop? Also the spark timing is all messed up, it feels like spark is wayyyy too late burning on the way out throught he turbo. I am thinking of taking a spark map from a CTSV as a starting point. Is this a good or bad idea?
Here are some pictures of the kit I built:
