Discuss you data logs that you have recorded on your DashHawk.

I just did a run in my car using version 2.4 Beta 9. The main thing I am watching right now is Boost and A/F ratios.

Conditions - 19 degrees and sunny.

Peak Boost was 18.85psi with an A/F ratio of 12.84.
A/F ratio - this one concerns me. I saw an A/F ratio of 9.54 at 5319 rpms and I saw 10.76 at 5123 rpms.

Why does that concern you? It looks pretty normal to me. Actually its pretty rich considering you're boosting almost 19psi. Now is that spike or steady at 5100+ RPMs?

You should post up a screen shot of the datalog in question. But make sure you zoom in on the section of the log that your concerned with. I've seen a few people post up logs that show 60-200 seconds worth of data. Its hard to see whats happening when others are just looking at a pic of the data. The DH software makes it really easy to zoom on the region of interest.

I noticed on mine when i backed off the boost down to 16-17 from 18-19 it didnt run 9 af's any more. Its like the pcm still nows theres somehting up even with the BCD on it and tried to throw fuel at it. IMO

The next time I do a datalog, I will post a screen shot. As for the A/F ratio, it was just a spike.

That is easier said then done. I don't have a MBC.
