2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

That doesn't sound right at all. We know that @MOC221_ 's Ginger 2.0 took the tune well.

You could either reach out to OVT incase there is a problem with the tune or try to reflash?

 

I’ve noticed a very slight delay for when the computer will resume fuelling when getting back on the throttle after an up shift. Not sure, but I think this may be a simple by product of drive by wire.


** only noticed during spirited driving

 

When I flashed 2.0 SFOB it did take a few miles to get rid of any peculiarities. I did reset LV as well and when I did my first drive to work (30 miles) she was good to go and no questions sense.

 

Reflash might be good. SFOB 87 again? reset LV again? if i reflash should i flash a different tune then the SFOB 87 or just reflash the SFOB 87 over the current tune.

 

got 100 miles on this flash with everything from around town to interstate speeds

 

I would do the same tune so that you know. Yes. I would use the same process. Flash following the prompts, test start, off, on (no engine start), Resets, start, idle, drive.

 

I went for the stars straight out of the 2.0 gate... SFOB Premium with a full tank of 91 E0. Reset LV right after flash, did the idle learn at normal operating temp.
Drove like shit for the first few km, then sorted itself out. I have to be careful with the skinny pedal in 1st, the thing takes off like a scalded cat when it hits about 2k lol.

 

TIS should work with out internet conection ,also my version witch has a thirty time use is resetable I will dig up instructions

 

Mine did this as well when I flashed to 2.0 Base, but it cleared up after about 10 miles. It still felt like it was missing/hesitating a little until I got about 50 miles on it. It now is running smoothly and I like the throttle response.

 

I used the premium file, since it was the only one that existed at the time.

The real strangeness lasted for the first time up through the gears. Felt just about normal after that.

 

Without knowing the code, it's strange to me that the truck would run so poorly until it sorted itself out, but it definitely does (sort itself out). Most of the software I have been involved with developing has some base that get's it very close to operating "normal", then tweaks the values as it learns. I guess with all of the parameters in these damn trucks (AFIC, fly-by-wire throttle, VVT, etc.) there may not be a "normal base" before the learning occurs.

Regardless, Mat has done wonders with this tune, and if it acts a little weird right after flashing, it's worth the end result!

 

Is the temporary dead throttle gone after taking off in first?

On stock tune, right after you take off in first it will act like it's ignoring all throttle input until it hits about maybe 1500 rpms. That's if you clutch out quickly and didn't give it much gas, but you're immediately giving it the skinny pedal once you're moving...and it feels like no throttle response until it gets to maybe 1500 rpms. Then it does what your right foot is asking for, but before that rpm it just ignores whatever you're doing with the accelerator pedal.

And I'm not even talking about bogging the truck while taking off either. This is without bogging. I've gotten into the habit of riding the clutch a little when taking off and applying more throttle to avoid this most of the time.

 

it doesn't do that any more. or even in 2nd really unless you are completely stopped.

 

Very nice. Second gear being more useable going slow would be awesome as well. I've even considered re-gearing as low as possible just for this reason (when I upgrade to larger tires later on).

Wish I could say I will place my order for a tune today, but it'll have to wait a little longer. Ugh.

 

This is off topic but this thread is more active than the thread for the product. And a lot of us have it.

For anyone with the Hurst(core) short throw shifter. How's the gear noise in terms of volume? And sound.

When I'm in 4th about 40mph give it some gas to accelerate I get kinda a tap tap noise. Could just be gear lash but not sure.

I don't think anything is wrong is just like y'all's opinions

 

it's noisy in my truck, but it's weird that it changes in volume and sound quality. I've noticed a number of things that seem to affect it like ambient and driveline temps, hand pressure on the knob, etc.

i was using a wonky knob with a multi piece extension, and i think that was a big part of my deal. but now I've got a new knob with no adapter or extension, a new clutch, and the transmission is going back in today, so I'll get more info soon, next week.

 

It might have something to do with 4th being direct drive. The secondary, shaft being unloaded, could be making a bit of noise?

 

What issues are you having? I had a 2009 xrunner and it had to go in at about 36k....had the entire tranny tore down to replace the aluminum input shaft because the TOB wore a groove into the shaft. I've been remaining hopeful that, that is no longer an issue

 

no issues, performance upgrade.

except for the pedal and master cylinder. I'm replacing all that with FJ and Land Cruiser parts to go all metal as well. this has been planned a long time. the stock POS pedal assembly has been my nemesis holding the truck back.

 

Factory pedal assemblies have been crap for some time, the 2009 squeaked like I was kicking a dying bird. I can tell it's only a matter of time til this one starts. The biggest change I want to make to mine is the auto fjcruiser tcase. I've just been to scared to pull the trigger haha. I'm just not ok with this turn knob 4wd business, and I know I never will be.
