Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I think you have all the resources to do the update yourself. TS V14 keygen can be detected as Trojan by AV program. But after getting the key for TS you can scan your computer again and delete the keygen if you want.
I posted TS V14.2 and the keygen in 3rd gen forum with mega.nz link and the thread was deleted pretty quick by the mods. Tonered reuploaded into his google drive for people in this thread.. Anyway, the TS v14.2 and keygen were extracted from garageforum.org, got to thank those guys.

 

More like a rhetorical question... I'm wondering how many are actually using any diagnostics software on their tuned trucks...

I'm getting misfires, which I reported to zendesk, I know others get them too, but you don't read too often about them. I'm talking about misfires that can't be felt at all while driving, only the software can record them.

I know some said they get them even on stock, but I have a (totally unsubstantiated) feeling that most don't know if they have misfires or not. They assume they don't if the truck feels good.

I don't know.. is it important to not have any misfires, or as few as possible? I'm not a mechanic, not even an armchair mechanic, I'm just wondering.

Do we care? Should we care, or just be happy the trucks run better, and that's that?

I'm definitely no criticizing OV tune in any way, nor do I imply it's bad for the trucks. Like I said, it looks like even some stock trucks misfire. I simply don't know and I'm curious.

 

Nope, nothing for 04A60

 

Already did

 

I’m gonna assume that the majority don’t monitor/log. Those who do, provide valuable information to Mat because we are a “sample” of the customers, and provide a good basis to determine how widely or narrowly these trucks are afflicted with certain conditions (good or bad). And the more detail/context we provide (logs) with our feedback, the better. I feel like it is very important that Mats logger be up and running because it is an “easy” way to provide very important information (wish it was working) hint, hint...especially during all this testing

OBD Fusion and the sort are also extremely easy but are not at the level of Mats logger (I assume) or Techstream. Techstream is actually pretty easy too... especially with the support from this forum.

That being said, there are trucks that have higher misfires tuned than they do stock. According to Toyota, they are still few enough to “not worry about”. I personally now of 4 members of this forum that have discussed their concerns with me and are working with Mat to provide the info needed to get the misfire counts as low as possible. I’m looking forward to the day that I can jump in the truck, turn it on, throw it in D and just drive without thinking about the way it shifts or how many misfires I have. I believe that day is coming.

 

Amen to that! Actually, if the shifting will never be "perfect", I still won't mind. I just don't feel too good about misfires, because those have the potential to do damage.

When all is said and done in future releases, if the number of misfires will be lower on stock than on the tune, I know I'll get back to stock and call it a day. It will be a tough pill to swallow, money lost, but at least I'm regeared. For now though I'm hopeful.

 

Are your SURE they are misfires and not the torque converter? The TC can feel very much like a misfire when it engages/disengages

 

That's what the software says, cylinder misfires.

 

Oh sorry man, I misread.
You said so bad you can “feel” them.

Believe it or not, Toyota’s stock tune had misfires too. Wonder if it’s just how these new modern machines are...?

 

I believe it. I will go back to stock in a few days to see how it does.

If it has the same number of misfires as the tune, I'll tune back. If I have fewer misfires on stock... I'm thinking of staying on stock... I don't like it, but what is "acceptable" number of misfires and what is "too many" misfires? I openly admit I have no clue.

 

Mat has mentioned that misfires really aren’t a big issue when they are minimal. I’m sure I have them and don’t know it, but I sure as hell am NOT going back to the stock tune.
That would be about the equivalent
of a shotgun to the D.

That's the question, what is "minimal"? Some have a few, I have up to 13 in 10 miles, both on cold and warm engine. (Maybe this was discussed somewhere in the tens of thousands of posts, but I couldn't find anything)

 

I understand the concern about misfires, but there's a couple things that need to be considered.

First, how Toyota calculates what a 'misfire' is and the sensors used to calculate said misfire. You have the camshaft positioning sensor and the infamous CPS. Is there a margin of error with the sensors used to calculate a misfire? If there is, I wouldn't be surprised considering our CPS history.

Second, it is not unusual to see misfires when the ECU in open loop, running pig rich (cold engine).

There is also something to be said about how many recorded misfires it takes to prompt a CEL. It would be interesting to hear @OVTune 's take on the matter. I personally do not feel like it is much to be concerned about, and would be much more concerned about potential detonation considering our high compression ratio and lack of premium fuel requirement, although that seems to have been mitigated by the D4S fueling.

 

Your truck won’t throw a CEL until there is some stupid number of misfires. I don’t remember how many but it’s a lot. I personally wouldn’t rely on Toyota’s idea of what you should be concerned about.

I’d say 1 or 2 per 5 miles is somewhere around acceptable. Less is always better.

 

Say good things to your truck and give it a nice wash...#’s will come down

 

Then I'm already above acceptable with my 13/10miles ... damn...

 

Thanks, this is exactly the kind of stuff I don't know anything about and I appreciate the education.

 

For shits and gigs run some Lucas injector cleaner in it and burn a tank of quality fuel.
6-7oz should be cherry.

 

Depends on who you ask. Someone will chime in with the answer, but your check engine light isn’t concerned until there’s a lot of misfires. Toyota says your fine.

 

Here is a good rule of thumb. If you can feel or hear a misfire, you have reason to be concerned. A CEL will certainly confirm this as well, as you likely will not feel or hear a misfire without provoking a CEL. Those are the kind of misfires that will potentially cause a problem.
