Cali verses 49 state differences?

Hey there SC experts! I'm real curious of the differences (if any?) between the 1995 SC400 I'm getting next week that was originally sold as a Calif model, as opposed to a 49 stater? Please chime in!

2 that I am aware of are:

-4 O2 sensors instead of 2. 2 primary and 2 secondary.
-ecu is programmed to run on 91 octane gasoline vs 93

Thank for the info Brian. I assume that those 2 additional O2 sensors are on each side's primary Cat Converters. I'm hoping that if there's a 3rd converter downstream, as someone said, it'll just be a passive type that can be removed if desired. Once I take delivery of the car next week, I'll be underneath it fer sure!

Correct. It will probably have 3 cats like an OBD2 SC400, and just like OBD2 cars you can remove it and not get a CEL

I know it's not the same model but when I went through replacing a bunch of stuff on my SC300 I think I recall a couple things

-Different injector P/Ns
-Different throttle body unit P/Ns
