UPDATE: Have plugged in and transfered tune data to a new/used known good ms2, and all seems well. Immediately the MAP was reading atmospheric like it should, and my entire fuel table wanted to come down around 40 points. Car drives like new again and am very happy. Should be a sure thing if it does well on the way to work tomorrow morning. Side note, where should I send the other ecu to get fixed? I assume it's possible anyway.

 

DIY autotune fixes them, send them an email.

 

Got it. Thanks for the advice with this issue overall!
