2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Growing up in the old days, it is hard to think of the throttle as a sensor. That is all that it is in today's world.

The ECU takes input from all the sensors (actual ones, plus driver input, and other buttons and switches), and decides what output is correct.

That can cramp the brain.

 

So if I amreading this correctly even after flashing with ov tune, the stored settings from sprint booster are not changed? If i disconnect the battery will the sprint booster settings be removed?

 

Correct.

I have no idea. What happens when you disconnect the battery now? Whatever happens will be the same with the tunes.


The Stock base code is a large part of the OV Tunes, which change significant parts of the Stock tune. This is why is it suggested to be on the latest TSB tune. 04A71 in your case.

 

Is there a way to remove stored settings from sprint booster without plugging it back in?

 

Sorry, but I do not have a SB or PC. I just know what they are and how they generally work. You'll have to look at the instructions or FAQs on the site.

 

Isnt the setting just like 0-9? I dont think theres anything special in it..

 

Yes, but after setting it to your preferred settings, and unplugging it, those settings are saved. I want to know if I can delete those settings by reflashing with ovtune or some other way?

 

The SB and PC just mess with the signal coming out of the TPS before they get to the ECU. OVT is not going to change that.


Some other way is going to be the SB setup device, which is outside the scope of the tunes other than the possibility of a very twitchy throttle.

 

Any presets are stored in the SB itself. The SB doesn't make any changes or save settings to your ECU.

 

The settings are in the sprint booster itself. It doesn’t do anything to the truck. It just saves it in the SB, no different than if you were to turn the truck off.

 

So once I remove sprint booster from the truck the settings are removed?

 

Yes.

 

I don’t check in on the forum very often anymore and been content with the Prem 2.0 91 tune. I’m an original dongle kit and just learned from others posts that Ovtune will give you free Vftune and tune pack for sending in your dongle? Seeing that there are no new tunes outside of 2.0 being released, and knowing I will never go and edit my own tunes, is there any other reason why I should give away my dongle and freedom to use any computer I want? I’ve already had multiple laptops since purchasing this kit years ago, and being able to use my current laptop has been great.

 

Going forward, if there is an new TSB tune (prettly likely), it will only be release in vF. Of course, you can make a decision at that time.

 

gawd i hope this is the very last q&a of this here in this thread. asked & answered buddyro. @Mike2121

 

Charging value should never drop below 13.2v for AGM under any circumstance. I would probably give it at least a .1v bump for a safety margin. Default values will drop below 13.2v at high temps.

 

The orange connector is not a dongle. You'll need to pay $70 for the upgrade. If you have the dongle (not sure what it looks like, but it's not the orange OBDII connector), then yes, it's free... but you'll need to buy the orange connector, I think.

 

No, the maximum output of the alternator is 14.8v, which is perfectly fine for the electronics. I don't see how it would overtax the alternator, either, since it's mechanically designed for that. The only possible "problem" you might run into is overcharging the battery, especially if you aren't using an AGM.

 

Hey folks!

Ever since 2.0 Final dropped I haven’t been following this thread too much. I’m currently running SFOB premium on my 2020 MT Pro.

I’m experiencing the surging issue that has been described many times over in this thread. It feels most prevalent in 2nd and 3rd, typically at lower rpms during acceleration. Starting around 1500 rpms. Heavy acceleration seems to iron it out a bit.

Today I’m going to re flash back to stock, drive it a bit, then flash SFOB again.

Has there been a fix documented? What about VF tuner?

Thanks in advance! @Shellshock @tonered

 

Like you are seeing, it seems to happen a while after the tune has fully settled. We have been able to minimize it with some edits. See the vF MT thread in the Perf and Tuning section for all that we have done.


I am very happy with an edited tune at the moment. I have been able to let it be for a month or so now. With almost four tanks on this tune, a bit of that surge is coming back, but it is less than it was. Given that, it seems to solidly be in the learning camp, which sucks.

Maybe @OVTune can discuss some of what can be done about long term learning or where that might be hidden, even if we don't have access to it?
