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) Greets |
To show the log portion you want, you might be able to "print screen", paste it into "Paint" and pull out the section you want to show us.

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) http://www.ingenieure-reichel.de/upload/2008/log1.jpg second (from the same log) - specially the second right "pull" AFRs instantly dropping to a flat 9.8 http://www.ingenieure-reichel.de/upload/2008/log2.jpg Any help appreciated. |
Where is your AFR reading coming from and is there any real-time "feel" to the change?
|
AFRs are comming from my ZT-2 wbo2, through the 2nd option port. (I have a selfmade connector maybe its an issue there?!)
The realtime change is noticable as stumble. Greets |
My first guess would be that your O2 clamp voltage is set too low or absent.
|
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.

Just a thought - is it possible, that my sparks are getting blown out at this points?
