I recently picked up a second hand Enhanced MS2: https://www.miataturbo.net/miata-par...and-new-81207/

I'm not an MS newbie, but I have a few questions before I do anything too stupid.

I believe this MS2 is capable of sequential injection, and I know my 1990 was not wired for it originally. I'd love to upgrade but I'm not sure what pins at the ECU I need to run the 2 new wires from. The PDF I received doesn't mention sequential injection. I don't think it's part of the DB37 plug. Can anyone give me some pointers?

In the meantime, before I blow something up, can anyone help me make sure my basemap is running in batch mode? The settings are a little vague (and I've been reading in circles on MegaSquirt Engine Management Systems).
