Slightly lower target idles, slightly less MAF correction and minimal (or no) changes to the ignition timing (since that's the most likely change to throw a CEL). That's the plan.
Cold start is hard coded, it will always act the same way with the injections cycling and all no matter what you change
So yes it is just a taming

Ignition timings triggering a CEL doesn t make sense...
