that's overrun cutting fuel most likely.

Thanks. I've been trying to upload the log. It keeps failing. I even trimmed it to under 2mb. I'll try again after lunch.

I uploaded the log to my Microsoft Skydrive - https://skydrive.live.com/redir?resi...FF355C0D68!123

Besides the over run question, I have a few spots above 100MAP and 14 AFR that I am curious about.

what makes them so curious?

I read that over 14afr in boost is bad. I checked my other logs. Usually there are maybe a dozen hits on the scatter graph during a 30 minute ride where afr >14 and map >100.

is constant or just there and gone?

It is for a very small amount of time. See the image in my previous post - https://www.miataturbo.net/showpost....0&postcount=18
I've also attached a few more graphs here.


And then is my lean/low map normal/safe? I do have over run at >2k rpm, <20kpa.

i wouldnt worry about that.
