TSB-0092-20 is awesome!

Thanks gForceDude

 

I had an 11/2019 build that was eligible and needed the newer version.

 

My VIN is “eligible” but as others have said you have to check with OBDII. I took a screenshot when I was in the truck then compared to the TSB. Ending in “B8100” and “10100” is the “New” Calibration ID for a 2020 per the TSB.

 

If anyone is in Orange County, CA... I can help you. Just throwing it out there. Save time from messing with the dealership.

Just did mine yesterday at home.

 

Finally got 92-20 done on my '19.

Very happy with it so far from the ride home.

 

The shifting is incredibly smoother in my 2020 OR

 

Yea, I usually have to shift into S-5 when heading up a small hill to keep it from hunting but now just kept it in D and it did fine.

 

Do we know if this resets the learning process?

 

my understanding is yes it does... which is okay

 

Is the truck "always learning", or is there a set learning timeframe after the re-map?

 

About 500 miles - that's what I've heard people mention around here for the 'learning' time frame.

 

I've heard it's always learning but I have no clue because I'm always learning about this truck. Just drive it like you stole it.

 

My 18 was noticeable and responsive to the update on the drive home from the shop. Works like a lucky charm.

 

How do I teach a Tacoma transmission properly? What's best practices? I assume if you and I want a more responsive truck, you should avoid slow takeoffs.

 

The best way is to wipe the slate clean. Reset the DTCs, Learned Values, and AT. Do a 5min idle and drive however you do.

Otherwise, this seems to be how all ECU learning is. If you drive relaxed, it will eventually get too relaxed and be flat on it's heels when you want to have fun. Our old turbos were really bad about that. It would take a few full throttle runs to get them back in the game. Same if I have to drive my wife's car. Just a limp throttle until it comes back around.

 

how do i find out what ECU version is loaded on my truck?

 

Scheduled my fuel pump recall and TSB update for this Thursday. Hopefully it finally fixes the trans. If not OV Tune is next.

 

It will fix it for sure . The truck feels great now actually getting better and better as it learns. Smooth quick shifts.
