MegaSquirt A/fr Target Table
 

If someone more knowledgeable than me can check my table to see if looks decent enough to run? Stock NA6 by the way...

Why is it so.. all over the place? What is your theorie behind it?

You can easily use 15.5 AFR till 75, 80 kPa, and put 12.8 AFR in the top row and interpolate the in between rows. It will just use a lot of fuel if you target anything richer than 15.0- 16.0 in the cruise area. The idle columns can be put at 14.7.

You can just use a basemap AFR table. it doesn't matter that it was scaled for boost because you don't need that much resolution for the AFR table anyways.

That table sucks. Easy button download one of the better basemaps from diyautotune: MegaSquirtPNP by DIYAutoTune.com or truboKitty: https://www.trubokitty.com/#/tune and copy their AFR table until you are confident in your ability to safely makes changes to it.

Were you tuning the AFR table instead of the VE table?
