Matt, I just switched nistune over to my new laptop. Only ran in to one problem which was related to the one which I started this thread about. I am receiving 2 different readings from my wideband (lc-1). On the initial window which pops up I start the connection to the wideband in nistune, I see what looks to be normal numbers (around 14 say), but on the fuel map and any other window i get weird readings (around 8 or so). I am receiving these simultaneously. Mind you my new laptop is vista if that matters.
