2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Great info. Thanks!

That pretty much settles the worries in my mind. At that point, duty cycle would just be burning fuel and shunting current?

 

I have a bluetooth battery voltage monitor on each battery. If you measure it through the ECU, you get a drop in voltage. I get 14.6v at th battery and like 13.something through the ECU.

I think mine flickered 14.9 a few times when I was playing with values at the beginning. I can't confirm that. I mean I could do it again, but no thanks hahaha.


Thanks guys. Charge cycles would be a killer feature.

 

It sounds like you are in good shape?

This was posted yesterday. I doesn't jive with what I have seen, but I didn't have my phone near the battery.

 

Obd vs bluetooth monitors on the batteries. All good here!




A multi meter would read closer to 14.7. Same with the diagnostic logging tool thingy ovtune provided

 

I was typically seeing less of a delta than that. Fun stuff sometimes.

It seems that you are on target though.

 

Negative valves, my developer is going to fix this when axis editing releases, he just has a few complications at the moment, possibly from him contracting covid.

 

Ok so I've been with ovtune since 105 and was originally in a 17 AT. Now I'm in a 20 MT and instead of reading all 943 pages to catch up on this thread can someone give me their opinion on Reg OL vs Super FOB? I'm assuming the dump files are for those with dump tubes.

 

If you are stock, either one is great. If you are lift / tires / etc you definitely want SFOB

Basically SFOB has some more power.

 

Well I was all good and ready to flash because I had seen a few people say the 20s are ecu id 04b90.... until I saw this



Is this something @OVTune is currently working on or do I need to zendesk him

 

Congrats, I’m pretty sure you are the first 04b91

@OVTune

 

Had it special ordered and waited a little over 3 months. Came in on the 2nd..... a little early bday present to me!

 

Get a message off to OVT. They will probably need a dump out of your ECU since there is no TSB for it. There still isn't for the 2019s.

 

The headaches never end for Mat lol..

 

When did you get your truck? I wonder if yours was built near the release of the 21's and that's the calibration their getting.

 

Most likely the 2021 will get completely different ECU IDs like the other years have.

 

While anything is possible, carry over of original factory cal ID from M/Y to M/Y hasn't happened yet AFAIK..

 

Order for the truck was placed May 15th and truck was delivered to the dealer Sept 2nd. Wouldn't be surprised since its a late 20 that this could be the new ecu id for 21.

 

Click "READ"
save the file, don't rename it
email it to us Support@ovtune.zendesk.com


This is a brand new calibration ID, support will need to be built.

 

Can do... expect the file between 330 and 4pm this afternoon when I get home from work.

 

@OVTune..... ecu dump sent to zendesk. Thanks for all you do.

Everyone else.... since there's so much less to complain about in this thread can anyone point me in the direction of the best techstream for 2020s? The one I had for my 17 won't work for whatever reason.
