MSnSe, fuel only, 100% stock miata

Ok, so I used the generated VE table from MT, got the idle nice and smooth and low kpa, and then did a little autotuning and manual smoothing of the VE map, I took it for a drive, and the thing seems to be running extremely well. (I've barely done anything!) It holds 12.5-13 AFR under full throttle accel, and under cruise it runs at 16-17AFR. Idles smoothly at about 28 kPa,and all seems well. Even gave me the confidence for several WOT 6000RPM runs. I guess I just want some of you experts to help me find out dangerous points in the map.

I have not set up AE, and TPS is not being used. Also, CLT is still reading about 20F too low.
What do you guys think of these logs? :RTFM:

Not sure about your situation, but I for few days (on and off) I was trying to manually tuned for idle ve map I found on the internet for my engine, thinking it would be the best place to start, with really bad results.

frustrated I generated a new table with the table generator, just to see how it works. and :shock: I cant believe how well. Starts quick, idles rock steady with lower map that I ever could achieve, revs faster and comes back to idle faster, and idle is very steady, instead of the hunting problem I had....

feels soo good now that I'm ready to take it up and down the driveway :)

enrichemtns need working on, but generated base map feels so good...

Yes, strange isn't it, I was hoping for something very rough just to get the car started and it turned out to be very good. As in, almost like stock with a little tweaking good.
