Wideband O2 installed
« on: June 08, 2014, 08:53:58 PM »
I purchased an AEM wodeband O2 gauge about 3 years ago to use with the Megasquirt EFI conversion I want to do some day. I'm off work for two months due to a shoulder injury and have been going stir crazy being trapped at home and low on funds. I decided to install it today. I had an O2 bung welded on the exhaust a few months ago when I had the exhaust redone for the AW4 swap. After spending some time trying to figure out where to mount it, I decided to take the transmission temperature gauge out of my console and install the O2 gauge in it's place.I thought for sure it was running a little rich and could squeeze a little more MPG out of it by going a little leaner. Well, it turns out I've got it tuned pretty darn good already. It was in the 12's at idle and I adjusted the air mixture screws to be in mid 13's. At part throttle cruising, it's at about 16.5:1 which according to the video below, is best economy. It's in the low 14's at WOT. Technically I could go a little richer. I may try that to see if there is any power difference, but it runs great now with no pinging.

I have an auxiliary cooler and installed a tee into the return line.
