Still searching EFILive for a solution but not having luck. Posting here as I continue my search.
Cold start up runs 17-18 afr until maybe 175 temp is reached. Once it does It goes back to where it's commanded, and then a few minutes later it richens up to 13-14 instead of 15 where I want it.
Any tips or links to threads are greatly appreciated. Just trying to get my tweaks figured out before I drive back home after work.
Since i'm at the 500 mile mark I plan to make sure my VE table is dialed in. Still kind of skeptical about the wideband accuracy whit the EFI reading.

So small variables. I was reading on EFI and some people are having problems with it not working. So i'm hoping i'm not one of them.
Everytime I start the truck and I see --- on my wideband my toes curl (pun intended).

Bumping this thread. The above worked great until recently. After I put the stall in I've been redoing the ve table. Seemed way out of whack.
Now i'm starting upt at 14.8 and about 5 seconds later it leans out to 18.8. I've tried increasing these tables again but doesn't seem to be helping.
I'm working on the RAFIG process but I don't want it to sit there idling at almost 19:1
