I finally have my 91 318is with DA supercharger running again. I had the battery out for a while. Does the Motronic learn. The next thing I'd like to do is take it to a Dyno to check the AFR and see how healthy it is, wondering if I should wait a bit t for the Motronic to settle?

Yes it does, as it is adaptive.

Oh it learns. It's always learning. And when it has learned enought, it will overpower us and take over the world.

it will probably be really rich until the ecu adapts

It adapts, but only to a point. From what I understand, the DASC kit, if used as designed, can scrape by with proper AFR's. If things get too far away from stock proportions, it will toss a CEL, or just run badly.

This is true.

My car throws a CEL for 02 and Knock control every once in awhile now and only after letting it idle for more than a minute or two.

Other than that, it runs butter smooth.

Actually, my engine has been running better since the DASC install..
