ECU TSB Update

Thanks for keeping me on my toes @tonered @Shellshock

 

2018 DCSB MT. Langway Toyota Newport RI. They would not do the update for me.

 

Talk to @lapoltba he can get you taken care of

 

In prep for an initial OVT install later this week, I wanted to verify that a 04B81 CUW file is not available for 2020 AT trucks?

 

Correct. No CUW files for 2020 trucks

 

Still hoping to get cuw's for 04B24/B25, if they even exist.

 

Excellent! Thanks for the quick reply!
Slightly off-topic, but as I've dug into the ECU versioning and tuning, I am curious if the functional vs non-functional Crawl Control in the 2020s is related to the 80/81 ECUs...

 

That is a good question there. I do not have those listed in the 1st Post and will update it. The only breakdown that I see there is in TSB-0013-19.

04B25 is 2016 / 2017.
04A81 is 2018.

Transmission type is not noted.

 

81 should be 2020 no?

 

I know I came across a B24 AT, so idk what the Mexico/SA MTs are

 

With an 'A.' It took me a few blinks to catch on to that one.

Just highlighting what I assume is non-USDM?

 

The fuck

Whoever came up with this number scheme at Toyota is fired.

 

Whoever touched the 3rd Gen ECUs needs some tortured retraining.

 

Oh shit

 

Ha!


Thinking back, it may have been said that there are no MTs in Mexico? That was the HiLux department? Does that sound right?

 

Isn’t everything made in Baja now? Theres gotta be some

 

Just like the ACLB OR MT, it is there for just a moment before a fast escape to Canada.


Do any roll out the back door? That's a good question?


I did see a 2016 or 2017 Mexican market AT Sport in my next of the woods. So, some cross pollination happens. Not enough though.

 

So, it's been about 2 weeks of very rarely driving the truck, but I would say I have put about 65 or 70 miles on my 2018 AT DCORSB 4x4 after flashing:

T-0036-18.cuw is for 2018 AT Tacos with an ECU ID of 04A60.
Applying the update will give you 04A61.
This is the latest update for this ECU.

As is mentioned, the first few miles of driving were a bit odd, but it just felt like the truck needed a minor tune up or something. That smoothed out in a day or lets say 15-20 miles. Then over the next few days of driving, the truck just seemed to get better and better as all of the "learning" of the ECU etc was taking place.

Now, I can say that this has been a pretty major seat of the pants update for me. The truck feels and drives so much better than it did when I got it in November. The truck only had 5000 miles on it when I got it and when comparing it to my daughters 2018 DCORSB 4x4, I was really disappointed in mine, because her truck felt much more snappy than mine.... Now, after the flash and some re-learning, they feel pretty much identical.

Definitely worth doing.

Eliminating the seat belt chime was icing on the cake.

 

Good stuff! I'm glad that it help.

Enjoy it.
