in reply to pgfpro,
Lean burn is a simple re-writing of my target A/F ratio table on the Megasquirt.
The B3 Miata is tuned to run fat in the margins and lean at cruise. My version of lean is 15 -15.2 AFR.
Completely unrelated, but related... recently I have noticed some trouble with the wideband and megasquirt reporting different A/F ratios. I believe the trouble is with the megasquirt and is yet to be resolved. Anyway, running a leanburn profile will be one of the tests.
Jim
