I was adjusting Power Commander map on Harley with O2 sensor.
Yes, exactly. I had a friend install 1 on each pipe, right outta the head, maybe 8-10 inches down. It ruins the shiny mufflers and looks totally Frankenstein-ish, but I purposely left my old KZP all rode beaten and worn(like the old Blues Brothers mobile). It's a great running rebuilt machine on the inside, but you'd never know it by looking at it.
I plug a wideband sensor, one pipe at a time, and use an Innovative LM-2 to read. I love it. I can also mount the reader on the handlebars and take it out for a ride and see exactly how it does at all precentages of throttle. The trick is, IMHO, is not to get caught up on the numbers too much. If it runs great, and there's no major red flags, just let it be. And ride the heck outta that thing!
