Default 1990-2000 ECU list for North America (Yamae)

This list of ECU part numbers was complied by Yamae.

This will help to define which ECU's are in the North American spec LS400's. We've seen some different ECU's part #'s among the LS400's so not all are generically one part# for all models.

If your ECU has a different part# please post it in this thread.

This is not for capacitor fixes/requests. Any posts that follow the ECU capacitor fixes are to be posted in this thread:

As far as I investigate the variation of the ECU for the North American market, there are ECUs as follow.

My 98 came from the factory with:
89661-50432
When they changed it earlier this year they gave me an ECU with the following numbers:
89661-50560-84
