ECU TSB Update

2019 MTs and ATs have two ECU IDs each, but no TSB has been dropped as far as I know. Keep an eye out at nhtsa.gov (see below).

To get your ECU ID, turn the key to On, connect to the Taco, and look at the Engine ECU. It will give you the full ID as shown in the 1st Post. We abbreviate them for obvious reasons.

 

Looks great!
I would add to the “do not use Bluetooth or WiFi dongles” step that the Tactrix is a proven option, and other usb dongles aren’t necessarily

 

Thanks! I appreciate that.

Will do.

 

or cheap chinesium dongles unless you like things not working and bricked ecus

 

Posts 1 updated. Thanks for the input!

 

Nice.

 

Updated mine from 04B12 to 04B14 last weekend, cleared the LV it is definitely a better driving truck now, no more surge in 2nd. Now the question is to tune or not tune

 

Tune.

 

Nice work!


That is a tough decision that I struggled with on 04B13. When 1.05 launched, the MTs started to get some features. 2.0 now has a lot more specific features. So for me, it sucked me in.

For you, see what your situation is. What are you missing or want improved?

After driving with the tune for so long, my biggest gripe on 04B14 Stock was the missing low end torque. I typically drive in the lower rev range and that big bump is a big factor for me.

 

Thanks, @Ruggybuggy and @tcBob !

The 1st Post is updated.

If there is any feedback or updates, please let me know.

 

Thanks for keeping this going Tony

 

You're welcome!


I kind of thought this was tapering off, but all the new vF and 2.0 tune folks seem to be asking about the TSB flashes.

 

Welcome to our new leader!

 

Oh gawd. That is gonna be a bad trip.


BTW, it is funny that I liked the 1st Post.

 

Also you should probably put the link to this thread in your sig now that its the TSB master thread

 

Good idea. I will do that.

 

Thanks for the input. I definitely feel the low range is better now than before, I can hold speed much better going uphill without downshifting than it could before the update. That being said, I do most of my wheeling at much higher altitudes than were I live, so more low end torque is better, I’ll probably tune it in a week of so

 

You're welcome!


There was definitely a small power bump going from 04B12 to 04B13. 04B14 Stock felt even better, but it had been a long time since I had driven 04B13 Stock. So, I could not say for certain if there was an additional power bump.

Like you noted, with 04B13, I was able to use one gear higher when climbing.


OVT is a completely different animal though.

 

Hey, Folks.

I was just checking my Share settings in Google Drive and found the working Friendly / Unfriendly Dealer Map. ??

I added it toward the top of the OP. Can a couple folks test drive it? I should have no restrictions.

 

looks like it works
