I will grab another log here in a few minutes, I got the wideband sorted out yesterday, it was there all along but I just figured out how to get the Scanner to see it through the EGR. I am not going to drive it anywhere, it doesn't even have a torque converter right now so that isn't even an option. The IAT is in the intake just behind the throttle body, it is a GM sensor from a 90's 3800 motor.
Things I have changed but did no good, it is calling for an idle of like 700 which is too low but when I change it higher to like 950ish it starts and stalls right away, that is weird to me. I changed the PCV system back to stock with a PVC valve in the drivers valve cover and the other hose from the passenger valve cover to the throttle body. That seemed to help the WB reading a little, I suspect I was getting 'unmetered' air in somehow.
And lastly about the VE table, I took the entire ve table from a 5.3 turbo running 127lb injectors, what is in there right now is none of my doing but I figured it would get me close, then I hear words like inverted and WAAAAAAAAAAAy off and I wonder how a running tune could be that bad. Anyone have a good VE table 3bar, turbo, 5.3 stock head small ljms stage 2 turbo cam with big injectors?
I am going to go out an try to fail out the MAF and get another log right now.
is the thing, the WB says its terribly lean, the stock o2s say its lean but this is not lean, it can't be after 2 minutes it is eye watering can't breath clothes stink for hours rich.
