What model ECM is this ?

[Team ZR1]

Being the ECM is mounted upside down so that the E-prom door is on top for
quick chip changes
I removed the ecm and sure enough there is a tag on the top.

It read  SERV No 01228331
                  868821
              M910105000
               16068821
                   ACFB

Does tha clear upwhich unit and which CPU ?

Thanks,   John
