S2 Owners, Post Up Some Data Logs!
So I have been chatting up with the SARX guys on FB and we came across something interesting. Now we really haven't got to a point where people are familiar with the S2's ECU maps, so for all I know, this is "normal". I am interested in seeing what others' logs look like:
As you can see, car goes nutty rich at like 5K !?
AFR scale is on the primary axis (left)
MAFv, Absolute Load is on secondary axis (right)
RPM is on the X axis

Trying to find his dyno sheet, but Brettus, not sure if you remember this post from the S2 ECU Tuning thread ...

What do I expect to gain? Nothing really as far as horsepower. If they can figure something out to give me some ponies, great. If not, no loss. Am doing this to validate MazdaEdit can in fact do a S2 tune or not. If it does, THEN we can start looking at upgrades and FI for S2's that need a tune. I'm one of those that would like to go FI, but I really liked the little creature comforts of the S2.

As the user in question, while I wasn't tracking AFR's at that point, my dyno stayed fairly consistent from before and after coils. The rotary shop where my first dyno was done didn't map AFRs but tuner shop did. Have access to look at pretty much anything via obd port and DashCommand. Anything you want me to track?

Even the parts where it gets down to 11.5ish? That seems crazy for NA no?

It would be awesome if you could try and get a log like mine. I simply just did a pull to 8k while tracking AFR, MAF and Load. It would be interesting to see similar results...at least it would put my mind at ease.
