How can I get Tesla to stage firmware for a DIY part swap?

Does anyone know if I can use this option instead of using the OTA update method for replacing my gen 3 ecu to gen 4 for CCS compatibility?

I'm a little late to the party, but yesterday on my 18 M3 I was able to enter service mode at home using the described method.

A year and a half ago, you had to be on the WiFi at a service center but it changed and now you can do it anywhere.

Yes, it will work.

This new ability to access what I call "Service Mode Lite" seems to be intentional be Tesla to throw us DIYers a bone. However, it is nowhere near the full capabilities and info in actual Service Mode.

I have all the parts I need to install a "gen 4" charge port ecu, but no idea when my next software update might come through. I'm going to try to install and use service mode to flash the ecu this weekend. That's all I really need it for at the moment. Wish me luck!

Update: I installed the gen 4 ecu and flashed it in service mode successfully. My 2018 is now showing as "ccs compatible"

Can confirm, flashing the ecu in service mode works like a charm.

Is Service and Factory the only modes the car can be changed to?

That's a full config change. You need deep menu stuff for that. Service center level access.

Wouldn't you need another charger? It's the same basic HW but one is three 16 amp circuits wired together to get 48 amps on a single phase, and one is each wired to their own phase for the European market
