The only thing that I have done on my X-pect is to fit a 100 ohm resistance in series with the IA sensor. The X-pect has never idled well when cold and was prone to stalling but now idles well and you can walk away and leave it idling which I could never do before. I also have ECU hacker and have checked it out on the X-pect but have not gone for a ride and recorded the information yet.
