For those who have used the "Service Mode - Software Reinstall" route to update to the proper firmware after the ECU swap does the Software have to be downloaded again through WiFi or is it already stored for reinstall?

Can you confirm that 3 necessary parts are required only for older models and newer 2021 model only require Gen 4 ECU part# 1537264-00-B swap?ECU: $140+tax
Labor: DIY only, Tesla doesn't officially support CCS retrofitting but will sell you 1 of 3 necessary parts to do it.

Thank you!Older ones require bundle of wires, ECU and adapter.
A 2021 would only need the ECU and adapter.
Yes, you still have to do the firmware refresh.So sorry if this has been covered already, but for newer cars with the "stripped" ECU, after doing the ECU swap do you still need to put it in service mode?

It just reinstalls what's already downloaded. No download required.For those who have used the "Service Mode - Software Reinstall" route to update to the proper firmware after the ECU swap does the Software have to be downloaded again through WiFi or is it already stored for reinstall?
Very informative. Thank you.You don't have to use service mode if:
1) you wait for an update to come through "naturally" (same update process as ever) OR
2) you ask a Tesla service tech to push a "reflash" to your car - same effect as reinstall via service, or taking an update (it makes the "orange clock" pop up to install now/later).

Yes. It says so over the progress bar as part of the reinstall.But it identifies the different module and then makes the proper changes for it?
Service mode shouldn't be a problem, I live 5 miles from an SC, I was just curious about the process. First I have to find an ECU!You don't have to use service mode if:

Is there error code like "CP_a051 alert" showing on your screen panel that ever happend in @FalconFour retrofit.?I don't have any error messages after swap the GEN4 EU ECU from a GEN 3 NA ECU with FalconFour's kit. Work perfectly.
Dear FalconFour I want to make sure the "470-ohm" value of resistor you mentioned which is not consisten with "47K-ohm" on electrical diagram you madeThe 470-ohm resistor in this kit would probably be "perfect enough" for resistor tolerances. In my case I actually have this resistor kit left-over from my childhood Radio Shack
The 470 ohm resistor that FalconFour is talking about is what is added in series to a 2.2K resistor in order to obtain (nearly) 2.7K. It has nothing to do with the 47K resistor.Dear FalconFour I want to make sure the "470-ohm" value of resistor you mentioned which is not consisten with "47K-ohm" on electrical diagram you made
sorry! I misunderstood that . thank you so much. In addition, if I do the 'bundles wire' myself, Should I use 10K-ohm instead of 22K-ohm according to the FalconFour final confirmed,diagram.The 470 ohm resistor that FalconFour is talking about is what is added in series to a 2.2K resistor in order to obtain (nearly) 2.7K. It has nothing to do with the 47K resistor.
exactly! I am able to do it tomorrow. thank you so much.Final answer from FalconFour are two 10K resistors and not the 22K resistors. Those were used in a previous design of the cable and later found to be not as accurate for sensing temperature.
Where do you get your wires?>> Wire (20AWG)
