Does anyone know if Toyota put the following ECUs in any other cars besides the LS? Toyota Celsior? Any other cars with the 1UZFE?

89661-50224
89661-50225

I'm am trying to track down one that has never been opened for my '95. I have the recalled 50221 with permanent drivability issue.

The ECU 89661-50224/-50225 is a replacement ECU only for an LS400 US Federal model which originally has an ECU 89661-50220/-50221. It has a newer algorithm to correct an engine idle speed reduction or a halt problem just before stopping the vehicle after a continuous long high speed run.

thanks for the reply. I will be calling junkyards across the country and asking their parts pullers to check all 95s for a 224 or 225.

Does anyone know a reputable place where I could find a: 1995 Lexus LS400 - ECM / ECU part #: 89661-50225 design for California emissions?
Thanks in advance to anyone who could help.
