Software update??

Good morning brothers and sisters,

I recently took Zulu in for my 5000 mile service. Nothing much, mainly just a fluid check and tire rotation. When I got him back, I went straight home and had to travel a bunch over the past week and half.

Before I sent my truck in, it had the hesitation and stuttering that I've heard people mention on this site. I never mentioned it to Toyota, but since this service, all of that seems to be gone.

No hesitation, no surging, it's smooth as hell now across the whole RPM range...

It's seriously like a whole new truck!

Is there a software update the dealers are pushing out?

 

Typically, we seem to have to beg for it:

If you have Carista or OBD Fusion, you can check your ECU ID. For a 2018, the stock tune was 04A70 and the TSB tune is 04A71.

 

The dealer will put a sticker under the hood saying the update has been done when they do it.

 

Folks in the update thread have noted that does not happen very often.

 

Check the paperwork you received when you picked up the truck. It details the work done.

 

I'll have to check it out again, but I don't recall seeing anything regarding the software.

 

Do you have a log in for the toyota owners site? If so, you'll see everything there, that is if the dealer puts it into the system correctly.

 

Is this thread referring to the ECU flash?

 

I had mine updated last fall by telling them that it's stalling at high elevation (Automatic shifting TSB). I logged in to the Toyota owner's site and it shows as follows:

08/14/18Repair Order Number: 1019628
REPROGRAM ECM (PCM)

 

Hmmmm….So it's not showing on the customer website, or my receipt, but it is DEFINITELY different.
