Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

always turn the radar cruise off, just using "normal cruise". cant stand the radar cruise, personally. Ski

 

I am going to install my tune but want to be sure I download the right thing. I want to run the 87 base tune but there are two options for AT trans 0460 and 0461. What is the difference between the two? I have a 2018 off road dcsb. Sorry for the dumb question.

 

You need to identify your ecu to determine which you need. Follow the video in the first post.
Edit: ECU identification starts around the 3:00 mark

 

I think my ECU is bricked. Was running 19770 on my 04b31 2019. Decided to switch back to stock this AM before a family trip this AM. The flash failed. Asked me to retry or cancel. Retried and didn’t work again. Tried flash back to 19770 or 19800. Same story. Truck cranks but does not start. Couldn’t keep working on it as I was just heading out on a family trip and people waiting on me. Had to turn off car despite warnings not to. No choice as I had to be somewhere. Now flash manager won’t identify ecu or do anything successfully. Cool trick. I’m on the road now. Won’t be back to truck until tonight.

 

Sorry to hear. Hopefully its not and it was just a weird issue.

 

Seems like a lot of 2019s are going down lately..makes me nervous

 

How many have there been?

 

Not sure but the vibe regarding the 2019s isn’t good. I know of at least 1 other who had the ecu go down on a 2019 04b31

 

Then all of the 1.05 tunes for the 2019 04b31 being removed. I don’t know man. Just makes me uneasy.

 

It’s recoverable. Mat or many others here can assist with some things to try.

 

What can you do to recover it? I’ve got the same truck. Wouldn’t mind knowing what to do if this happens to me!

 

Hopefully. I’m not back home til late tonight.

 

I’ve had a couple flashes fail over the time I’ve been tuned. There’s not 1 thing that 100% fixes it but trying some things will get it going again

sometimes just a key cycle will get it to work

Clear dtc and try again

others have had to disconnect the battery and try again

you can also disconnect the battery and touch the two disconnected wires together. Then try again

Sometimes people have had to flash back to stock then flash a tune again.

usually one of those works from what I’ve seen in 2.5 years. Those are the most common fixes.

also make sure you are flashing the proper tune for your ECU.

This may help . from Mat .
Start with these steps:

Turn truck off completely.
turn truck ON, prepare to flash
Press "CLEAR DTC"
then try to flash.
If fails,
unplug battery for 5 minutes
retry flash. Should take right away

 

Thanks. Will try tonight. Wouldnt read or clear DTCs this AM.

 

Nice! Thanks for all of the info!

 

Wat??? Source on this? Why?

 

Radar cruise currently uses the stock shift logic.

 

Im debating on getting OVtune for my truck. The throttle respond drives me crazy all the time. Especially on highway on-ramp

 

If the things @Shellshock suggested don't work you will probably need to remove your ECM and bench flash it. 100% recoverable, but unfortunately in some very rare cases it can't be done with the normal flashing methods.

Also submit a ticket to zendesk so Mat is aware.

I have a PDF I wrote up with the bench flash instructions if he suggests that you do that.
