i didn't think the BMS had a MAF plug. thought it was only MAP and T-MAP for Stage1, and fuelrail added on for JB4.
back on topic, are you on the latest code for the Stage1. i remember awhile back P12A5 popping up and a firmware upgrade resolved it. i know P12A5 isn't on your list, but wanted to mention it at least.

they say that when you turn off the car, leave it off for 5-10 minutes before you start unplugging stuff because the DME is still active and will monitor anything done (trigger a CEL). the 5-10 minute time frame is where the DME's power is drained to the point of it not seeing what you're doing.
opening and closing the door wakes the DME up again.

Ok cool, was not aware of that! If I uninstall and clear the codes and there is still an issue then the CEL should arise again, correct? I may just do that with and without the BMS installed (correctly this time) to see if I can make them go away. I'd be afraid of clearing the codes and the problem persisting and no CEL to alert that (that is not how it works, correct?). Thanks for putting up with my chronic ignorance.
