This video is about to become far more important. Now that almost all EV manufacturers have announced their intent to switch to the NACS plug and partner with Tesla for access to the supercharger network, non-Tesla vehicles will show up at Tesla superchargers as soon as Spring 2024. All DC fast-charging providers have also indicated their intention to add support for NACS. Those of us driving older Model 3s will need to perform this upgrade to use the new NACS plugs at 3rd party charging stations. Within two years, we will see the new world of "one protocol, one plug," but many must upgrade their cars to take advantage of it. We don't need to buy CCS adapters to use the NACS plugs, but we still need to upgrade the ECU. This is a critical point being missed in all the noise surrounding NACS, and Tesla has yet to make progress in offering the retrofit.
I'm not very knowledgeable on this subject, but my understanding is NACS is agnostic to protocol and use case. If the supercharger supports CANbus (pre-NACS) Tesla charging standard (also used by CHAdeMO which is why legacy cars supported CHAdeMO adapters), then it will work with legacy Teslas. There's no reason why Tesla would remove this protocol on their new Superchargers since the negotiation is already possible with the Magic Dock stations.
@@JeffKubel I'm sorry if I left any room for confusion, but I did say I'm only doing it to gain access to 3rd Party providers. Maybe, it was the "one plug, one protocol" comment that you're reacting to. If so, you're correct, I should not have implied that superchargers will drop support for old Teslas and exclusively support NACS. I understand that and should not have written it that way. Good call out.
Worked on my 2018 Model 3! I did the upgrade not to use a CCS adapter, but to prepare for NACS. I paid around $150 for the part from Tesla and $50 fornttr vubdle of wires. Note that you don't actually need to pull put the weather stripping around the trunk to do the job. Also be careful reibstalling the olastic over the truni latch because on my first two attempts, the metao clip popped out and fell under the trunk liner so i had to take even more apart to get it out both times 😂
the model 3 service manual does not specify that the 12v and HV battery need to be unplugged or the vehicle need to be completely off. since there is no HV flowing through the ECU?
Reading the service manual it DOES NOT say to disconnect the 12V or the HV batteries. Take the trim off, change out the part, re-load the software in service mode and be done.
It says that the part in the description is limited to 180 kw. Is that just for when I'm using CCS or will it also limit my speed at Tesla chargers. I think they my Model 3 Performance can charge up to 250 kw.
Do you sell just the "A Bundle of Wires" without the CCS 1 adapter? I've heard that when other charging stations begin using NACS, it will be NACS over CCS protocol, so you'll need the new ECU even though it's the Tesla connector. Looking to future proof my 2018 Model 3, but not interested in getting the expensive CCS1 combo adapter.
It _MUST_ be 1537264-00-B. Tesla will not give you this info, as they don't know this info themselves. The "-80-" is the version without CCS support and thus would be an entirely useless upgrade :)
@nooshiofficial ended up buying different hardware with Tesla LOGO, and it worked. I currently have plug in CCS wall charger for $100. It works well on Model 3, 40A charge, wifi on/off APP. Too much hassle trying to get certified Electrician and then buy Tesla wall charger.
@tomrybold I had same problem, but resolved by buying the correct board with Tesla logo. Seller on Ebay from California. Asked first and confirmed with seller that is the correct part for '18 M3. TESLA refused to sell the part by itself, they said it must be installed by them due to high voltage. I ended up doing it myself with Ebay item. Good luck.

Is the Gen 4 ECU you sell a genuine OEM Tesla part?
I just finished, thanks for the video. 45 minutes from start to finished for me.

are you sure changing the ECU won't make Tesla ban you from superchargers at any point?
Does the ecu work without the bundle of wires?
thanks for the video
Do you have both ccs AND NACS adapters?
I would like Chris at TesStudio Tustin to install next week at the same time to save $
Thank you
Didi
thnks but when tesla did for me he didnt disconnect anything
If I have the computer, then that means I just need to add the extension?
@@aboodhassan3078 it should fix the issues. If you need additional support please contact our tech support at +1 (949) 992-7013

How about Model 3 2021-2022 onwards? I don’t see the CCS status in the vehicle information.
Yes it can work
To reinstall firmware do you need to be on wifi??
Need the link to the wire harness

Does only have to be P1537264-00-B or can it be P1537264-80-B to use ccs/ecu Fast charger?
Thank you
Please confirm with Tesla service for mcu model

i changed that ecu out witha thew one but car siad it cant be charged\ what did i do wrong thanks
😅I have the same problem. It works when undone to original.
@@Jc3805 i have a tesla appointment to fix that
@@Jc3805 did you reinstall firmware?

Ughh what year is your model 3
2018
Does this work in the 2022 Model 3 RWD?
Yes
Can this enable Tesla supercharger for salvaged vehicles?
Not sure, worth a try with new ecu
What’s this for i don’t fully understand. What’s the purpose
@@SergioERestrepo so you can charge using CCS adapter
For 1?.. you can charge at other Fast chargers other t
allow salvaged Tesla to also supercharge. So soon. Elon soon is lengthy.
@@Hansshow_Official where do you order this device and how much does it cost
