ECU TSB Update

Yes you are correct.

 

You're profile says that you have a 2021 DCLB. That means AT only, so you can only be 04C20 for early production or 04C21 for later production. The split was about May.

 

Thanks, this is for a friends 2016 taco.

 

Oh! Sorry about that!


Yes, then. As @AbnMP13 said, 04B04 is your target. Flash up with that CUW will update any previous version.


Although, 04B05 is a thing now. We do not have the TSB or CUW yet.

 

Hey, Folks.

I've been told that the TSBs now exist for 04C21 . . .














And . . .



















04B82.

 

04b05 and 04b15 probably coming soon

 

Hey, Folks.

I have the CUWs. I will get them posted in the morning.

 

But we want them now so people can update and then complain tunes aren’t available lol

 

LoL!

Practicing some delayed satisfaction.

 

Hey, Folks.

The 1st Post has been updated. It would be cool to hear from folks that flash up to 04B82 and 04C21.

Thanks!

 

Yo, for u guys that tune other trucks, what do u do when a new TSB comes out?? Do u call all the guys with trucks that have a new TSB and tell them or do u wait for them to contact u and request the update?

 

I wait. Also considering new tunes for these calibrations wont be out until after 1.3.0 is released, doesn't make much sense to upgrade them until then anyway?

 

I update folks when I have the tunes to go with the new ECU IDs.

 

...and here I sit with 04A61... waiting... watching everyone else flash, flash, flash... wondering... when will my 2018 AT get another update...

 

ty. does ovtune update the tune pack for free if u already got the old one?

 

Yes. If a TSB is applied, you can get an updated Tune Pack.

 

I hear ya, Tony. I’m around any talk of a 04A62.

 

That is the one that I have been waiting for. We know that 04B05 is shipping on replacement ECUs. You wanna be on the equivalent of 04B14 / 04B33. It's the good stuff.

 

I have a 2017 (04B04) so I will test the 04B05 when/if available. Dusting off the laptop now!
