Default A couple of initial logs- was WAAAYY lean....

Hey all-

1994 Miata- Stock at this point (I still have not built an intake, so still running stock AFM)

Brain built MS3 (awesome, Miata fired up first crank). I did install an innovate MTX).

The base maps had me running REALLY lean (I attached a log) so I did some auto-tuning and things improved a bunch (My log was too large- will run another and reattach).

I have tuned with Link before, but never with Megasquirt. Appreciate any advice. The car is running pretty well after a bit of the autotune.

I've never tuned using AFM or MAF but I'll guess that the base map discrepancies relate to the calibration of that device relative to the MS rather than anything troublesome. Autotune will get everything sorted out after a few hours of mixed driving. Hand smoothing odd spikes and dips in the table will take care of the rest. After you have autotuned all you believe necessary, view the VE table in 3D and look for cells that are uneven with those that surround them and touch them up by hand.

is the MAF still plugged in, cause you have no AIT reading.

What's the req_fuel set at?

****- it is plugged in now... I unplugged it and didn't reconnect.

Req_Fuel is at 11.4 now. It is running pretty well with some autotuning complete.

New log attached. Thanks for the help!
