Give it what it likes...keep in mind changing timing does have an effect on fueling as well.
As a rule of thumb, if you advance timing, should give it a little more fuel.
If it's too lean, and advanced too much, you can get knocking(detonation) much easier, which is BAD.
Kinda depends on what AFR really means with the Atomic system...how exactly is their wideband calibrated?
How do they convert & display AFR on the LCD display?
What exactly is 14.5 AFR, is it a calculation based on lambda from the wideband, or ??
May want to research this some on the forums with folks actually running MSD??
If you're running e10, AFR settings would/should be different than real gas.
Most tuners these days use 14.1 or 14.3 vs. 14.7 when running e10.
You may want to use e10 AFR settings to see if it improves how it behaves, and responds to tuning changes.
I only have experience with GM TBI, LT1, LSx , and Ford 5.0/4.6 systems.
So can really only suggest things based on what I've learned w/ them.
Kinda flying blind with the MSD, but "should" behave similar?
