Works a lot faster, lol! I've probably scanned and adjusted maf 30 times now. I know what your saying though. It most definitely should be a quick process. Russ, the guy who made the write-up, said it takes him minutes. 2-3 sub 7000hz tunes, and a wot tune.
I'll unplug my o2 tonight and see what happens. I considered it because that was his preferred method, but I'm definitely in open loop, no trims. So not sure why it would matter. Then again, I am always suspicious of the hidden tables in the PCM. Might still be some weird corrections happening with o2?
