Does anyone here know if an air suspension ECM 89293-50010 can substitute for an 89293-50050?
My car is down for an 50050 but I'm finding that one very difficult to get.

I don't know differences between 89293-50010 and 89293-50050 and sorry that I have no idea to judge.
There are 5 different suspension ECMs for Celsiors Gen1. Followings are them.
For models between Nov/89 to Aug/92, 89293-50020, 89293-50030, 89293-50040. (89293-50020 can be replaced by 89293-50030 or 89293-50040)
For models between Aug/92 to Oct/94, 89293-50050, 89293-50060. (89293-50050 can be replaced by 89293-50060)
Above information is from a service bulletin. I have tried to find the difference and the compatibility between earlier models and latter models, but nothing was obtained.
The suspension ECM 89293-50010 can't be found among them.

Good morning Yamae, I have been a little busy hence the reason why I took so long to reply. I appreciate your comments and at the same time I remember a post you made concerning the classification of the part numbers regarding the engine/transmission ECUs for those cars that went something like this:
"Every LS400/Celsior's ECM/ECU has numbers 89661-50XYZ. Three digits after 50, I mean the last 3 digits
X indicates design level,
Y indicates market,
Z indicates the level of minor design change."
So I guess that should also apply to the suspension ECU. If it does I guess the one I am looking at should be able to work.
Thanks for your help. I will decide soon if I should buy it and post the results.
