Installing wideband questions
#42
I can see GVE is at 37 most of the time at 700 rpm, map is around 40-44 which is off, should be around low 30s so timing could be causing this and PW is still out around 2.8 while its in this area. still gair is effecting it and gbaro which causes Gammae to be at 104.

If the sensor checks out ok, with those pw and if my guess of it being to rich is correct when you finally bring fueling down enough it will go from --- to 10s
Where is the wideband location before or after any cats?
Is there a narrowband o2 sensor still in the exhaust somewhere?

from your last log I still say its rich because the pw is around 2.8 at idle area which is a bit much.
mine is around 1.7pw and 1.5duty cycle.
I would take fuel out around your whole idle area, bring all cells in 500-1500 20-45kpa down to 30 and see what happens.
also just because you bring down to 30 doesn't mean its running with VE at 30, there is still enrichments and whats not that will effect final ve output.
You may also want to disable MAT table correction by inputing the correct numbers to zero that out for time being. Will have to find them.
Forgot to mention, test this out for me.
With your timing light attach it to all the spark plug wires and make sure they are getting spark to all cylinders. I had once a old ms1 that wouldn't fire one coil pack and I was able to idle the car at 3.5ms pw at lambda 1 on two cylinder alone, still you smell the excess gas that wasn't burn, since the o2 sensor can't read this non burnt gas it wouldn't show up on wideband gauge.

when its at 60 its really making the wideband change, move it up to 70 and see what happens, seems odd though. but we are trying to figure out
Possibility two injectors aren't firing and its causing this issue.
Obviously as we add fuel it seems to richen up as we can see at 60 gve.
What engine related mods\parts have been added\changed\updated?
