    Default 6.2L OL SD e38 idle hangs high

    Last Sat took the car to its first show to mostly shake it out. It was only a ten mile round trip.
    Car ran great to the show idle was fine, started fine, and ran good till I got to the shop. When I slowed down the idle hung at about 2K. What?
    I have no clue what happened. Please look at the tune I was running 0006 and the tune I'm working on with a couple of changes 0008. ooo7 tune was a disaster...stumbled, hard start really rich so I reverted to 0006. I really don't know what a "good VE table" should look like. I don't know why the idle hung.
    I have included an excel file I created that shows the changes made to different tunes with param and desc. Hope that helps.
    I am a newbie working thru this with his rear ragged Thanks

    I looked at other tunes for other GENIV e38 engines and captured pics of the ve table in B8101.
    Can anyone tell me which would be used over the other...they are so different!
