Back-up ECU?
Members who purchased a back up ECU from the junkyard, did you make sure all the #s from your ECU match up?For example I have a 95, and in case I have a 89661-50220 1UZ-FE-0MI, will this work with a 89661-50221, 02/1995-08/1995? What am I looking for to match these?I plan on sending mine off.No I am not going to do the work myself

Have you read this post #8?
Some of 95 LS400s were known to have an engine halt problem when the car was aged and the firmware was needed to update to avoid the halt problem.

Not always true.When I did extensive research from Yamae and LS cowboy most of these are interchangeable89661-50220, 10/1994-02/1995
89661-50221, 02/1995-08/1995
89661-50230, 10/1994-02/1995 CALIFORNIA SPEC
89661-50231, 02/1995-08/1995 CALIFORNIA SPEC
89661-50290, 10/1994-02/1995 USA TAIWAN SPEC
89661-50291, 02/1995-08/1995 USA TAIWAN SPEC
89661-50302, 08/1995-09/1995
89661-50303, 09/1995-08/1996

89661-50340, 08/1996-09/1996
Even the immobilizer 96 might work
.After creating this post, I found some junkyards with 20 , 21 etc that will work.
I have found the 1995 are not as sensitive as other yrs.I even see other older years might work
