Emanage Ultimate oddness...
Hi guys,
I just try to describe my sometimes a bit odd emanage behaviour and ask you to give me some suggestions what might be the cause of this.
I am just about to refine my maps (using autotune and some own adjustments) - when I drive around and do some runs from low rpm steady accelerating to redline everything seems to work fine. Good AFRs (though still a bit to be dialed in)
When I drive and lets say I try to overtake a slower (about every other) car and push the throttle hard - my AFRs sometimes fall to 9.8 instantly and stay there no matter which rpm/psi. After a while everything works fine again.
What could cause this? Bugged O2clamp signal? OEM ECU going to safety mode?
Thanks for your help!
P.S.: If there would be a way to cut a part out of the log I could post some examples. (Because my log showing this is quite huge)

Well, yes, I thought about that, but what I was thinking about - if I remember corractly the EMb software was able to cut out parts of the log?!
O.K. here are two screenshots
AFR - yellow
I/J input - orange
I/J output - magenta
rpm - red
tps - green
first clean run - (just a little lean in the middle due to a not perfect map)
second (from the same log) - specially the second right "pull" AFRs instantly dropping to a flat 9.8
Any help appreciated.

My O2 voltage is set to 0.39V (btw it's your autotune re-used as O2clamp triggered by the EMU) But I am also thinking the clamp could have sent a wrong voltage at this point.
