ok so I got a little time to read some and take a short idle datalog. First, a little background...
About a year ago, I wanted a fox body but couldn't find one at the time so I got the next best thing, a miata LOL. Long story short, I hooked up a gen 1 mspnp to the 1.6 miata and a turbo kit. Put everything together, learned a little with the mspnp (on megatune) and it ran decent but I never could get it going how I wanted. The car had sparco racing seats and a nice roll bar. That car was just way too small so I sold off everything and put it back to stock and sold it. So the plan was to buy a foxbody because that's what I wanted all along.
I now own an 88 fox which I have installed microsquirt (ms2?) on. Now I am not totally green to tuning but I still consider myself less than novice. The car runs and drives fine after some autotuning. WOT goes pig rich but that's kinda what I wanted to remain safe while I'm tuning. The car has an on3(custom now, the only thing left from on3 is the turbo and down pipe) turbo kit, 42# ford injectors, explorer intake, AEM wb and that's it.
The issue I am having is once it gets warm, around 185 degrees or so it'll idle at around 13.5 afr, then all of the sudden it will shoot up anywhere from 16-18:1 afr. Its almost like its in some weird loop. It goes fine > lean > rich > fine... fine > lean > rich > fine etc.
I'm also confused about one thing, does the AFR table change anything if *incorporate AFR* is selected? That portion of my afr table was all set to 14.8 (I have since changed it to like 13.5). I thought the only reason why the AFR table was there was for when you autotune...
Anyway, ill attach my .msq and a short idle datalog. If anything looks odd please chime in, thanks
