Getting my ECU upgraded on 29 Aug. Wondering if the settings and associated FOBs are saved in a separate EPROM?
Both batteries are being replaced as well, so that bodes poorly for not having to re-select my settings, etc. Anyone have experience with this?
Wish me luck!
 
Count on all your settings being lost with the upgrade. It's best to take notes before dropping it off and reapply them when you get the car back. Oh, also turn off the easy exit setting before dropping it off so the driver's seat position can be saved to your profile without having to readjust it.

As for the fobs, those are easy enough to reconnect. Ask service to do that if you're concerned about it.
 
Makes sense. I'm curious how the boot-up-sequence may improve. I see random and frequent issues with the panel options if I go "too quick" from door-access to backing-out of my "carriage house" as-it-were. ;p For instance, for the entire drive, sometimes I get radio, sometimes not. Sometimes I get cameras working, sometimes no cameras for the drive. Sometimes the panel has an "Air" fuzzy Nav-background image on the panel, sometimes the standard dashboard. The Adaptive Cruise has always been jerky and unpredictable. The "Self Driving" feature hands-free or otherwise is far too unpredictable to trust compared to my CT6 Platinum Super-Cruise I'd use daily. Having twitchy responses I really don't trust any automation as the cameras are intermittent and the curb-rash-alert never works. Range and distances of the sensors are always off when displayed. My screens flip-out on occasion and glitch. I ignore all of those "comfort" features. The A/C and heat seem to rarely fail though, which is nice.

I think the software stumbles on boot-up with my slower CPU. Soft-Resets help the initial problem as it allows seemingly a linear and slow initialization from-scratch versus what seems to be a parallel load of several features at-once. Not sure on this. Not sure if they're using Java or something else. I never have a problem with the vehicle "important" functions though, such as that the blinkers, headlight and drivetrain always work, which is nice. I don't mind because 1111Hp and I never thought Lucid was a "luxury" car but more of a muscle-car, similar to a few Trans-Am Firebird SLP Firehawks I've owned, or maybe quality of a Grand Sport C6 Corvette with the 4LT trim. Interior and features are fairly mediocre compared to various Cadillacs I've owned, such as the ELR, CT6, or CT4-V. Reminds me more of an upscale Chevy. My hope is the ECU upgrade will assist in a better boot-up.
 
BLUF (Bottom Line Up-Front): I think the ECU upgrade will fix a good portion of my issues because things sometimes trip over each other in the load-bootup phase.

That's because this upgrade is only the infotainment system, not the ECU (engine control unit) which is a separate computer and apparently more reliable.

This. For me, my CCCv2 upgrade addressed some of the minor issues that you also pointed out. Even though it was just an infotainment upgrade, the snappiness of that seems to have made a difference in resolving general boot up issues.
 
This all makes sense. I think the "computer upgrade" will help those features. I'll give a full report to everyone on how it went on Friday.
I'll take screenshots of my settings. I wonder if they transfer some of those to the new system beforehand? Probably not. Login to Sirius XM, set-up face imprint, etc.
