ECU TSB Update

Facepalm.....thanks!

 

I had my dealer do TSB 0092-20 today on my 2020 TRD Pro

No problems asking for it and getting it done, but I did provide a copy of the TSB.

Here is the new sticker that was placed under the hood.

Just confirming this is the latest and greatest for the 2020 Pro and also would this have corrected the possible crawl control issue as well?

 

Hahaha! No. It is not the latest. You'll see 04B82 noted in the first post for TSB-0045-21. We don't have a PDF of that TSB yet.

At least, it should be a similar experience next time.

 

Is it at least the latest per the OP in this thread?

 

No. As noted, the 1st Post has 04B82 software and a TSB reference.

 

According to TSB-092-020 this is what I should be at on a 2020 after the flash.

 

Yes, but that is old data. The new hawtness, which is noted to fix the CC issue:

 

Ok well I’ll take it back at a later date and have them do the CC update.
Maybe we need to update the OP???

 

It is there. It's been there since June 22nd.

 

Dang must have missed it. LOL

 

thanks for the help BTW

 

You're welcome!

 

So I got a new tune file from Maggy for the 04B42 TSB update. I just tried to do the TSB update (with the CUW file provided in the OP) so that I can install the new Maggy tune for that TSB. I then got this error... Am I missing something? As far as I can tell from the chart this TSB applies to my '19 TRD OR 6mt.

 

Interesting. I know that other folks have updated with this file.

Thanks for the screenshot.

The big deal that I see is the Current Cal ID is starting with a V instead of an 8. My guess is that the Pro tune from Maggy is locked on a couple levels. Try flashing back to 04B41 Stock, then do the TSB update.

 

I'll gladly give it a shot and post back with the results. Any idea where I can get the 04B41 .cuw file? It's not in the OP

 

Oops! 04B40.

There was never an 04B41 CUW. I tend to forget that fact.


If needed, you can test start your Taco on Stock. Just don't hit the throttle or try to drive it.



Edit! You don't need the CUW. You need the vF 04B41 Stock file.

Sorry, again!

 

I remembered where it was right as I posted the reply, lmao.

I was curious (and took the same screen-cap that you did) what is that 04B42 file in there?

 

Should be the stock file for B42

 

I noticed recently in vF while flashing the change from 89663-xxxxx to V9663, have been curious myself about it
