cold commanded 10.98 idle why? can anybody tell me why im getting a commanded 10.98 at idle I can't see any reason for it I know my ve tables arent dialed in but why is it commanding so rich tt 400sbc 24x conversion
You say it's commanded and then you say it's not. I
would have to guess that maybe you're really talking
"indicated" from the wideband. There are PIDs for
commanded AFR (intent) and for wideband AFR (result,
subject to various error terms).
EQ vs ECT vs MAP is the primary table for cold / open
loop enrichment. What do you see at your idle-range
MAP and the ECT you're at, cell? 10-ish:1 is not at all
uncommon at cold-coolant positions. And this is only
intent, subject to "forward errors" through the fuel shot
calculation chain from things like a messed up low end
of the VE table (a universal outcome of swapping to a
bigger cam, needing work).
