Currently working my way through this tune. I've made some good headway with the MAF tuning. Today I decided to try getting the VE dialed in. When tuning the VE I get large swings in RPM @ idle and the car dies within a few seconds. Driving seems to be fine, for the most part. My first thought was adjusting Adaptive Spark Control, the car wouldn't die any more but the idle would still swing back and forth just much higher. With "MAF only" car idles and drives fine, besides a small surge coming to a stop, which it has always had with this tune.
