thanks Rod in AZ

Rod, I found a 3 1/2" slip-on tailpipe-looking thing at a truck stop once, that turned out on the end. I bought that, and slipped it on my collector for tuning the idle, and return road driving. my spark plugs now stay pretty much white, no matter how I have been driving it. FAST XFI ECUs, in closed loop have a mode where you just tap the L key, on a cell in the fuel table, and it will learn that cel. I just drove around the pits, and down the return road on a test night here at home, tapping the L key with mine. Saved it, smoothed the table out some, put it back into Open Loop. Has been fine.

Sounded more bad-azzed when I was driving it around too rich. LOL
