Pig rich during low RPM high MAP

Page 1 of 2Next

I've updated the software to 198i.  Now I'm going very rich during low RPM (2-3000), High MAP (70-90). AFR will go to 10-10.5:1 and the car lurches and sputters. AFR just stays there too, it doesn't try and lean out.

I notice in the calibrations there are adjustment for cam 1-4 fuel settings.  The settings are by RPM and MAP, Adjustments are in %. My questions are: 1) Percent of what?   2) Are these the base cam settings or are these the learned values.  3) Can these values be adjusted...specifically, for this event?

Your coolant temp is only showing 160ish.  Was the engine up to operating temperature? Fitech needs to see 170 or better before it turns off afterstart enrichment.

Try swapping the coolant sensor I have listed in the Parts and Accessories post.

It does the same thing at 175

175 on the handheld? Does that match your actual engine temp?

 

Yes, on the handheld. Yes, it matches.

I am not sure on this one.  I would like to see a 30 second idle log at operating temperature.

Ok, I’ll try after work.

Honestly, I got frustrated and reloaded the software. I just set the IAC so far, haven’t driven yet. If it’s still sputtering I’ll post a 30 sec idle log.

I am curious about all these new adjustments available on the new software. No definitions and no help from Fitech.  They said they’re “working on it”.

Some of the factory settings are not even within the usable range! Baffling!!
