OV Tune and warranty

The obvious action is to return any system that has been modified back to stock condition prior to going in for service on that system... i.e., add anytimebackup and then experience a Head Unit failure, return to stock before service... add OVTUNE and experience a drivetrain issue, flash the ECU back to stock... etc.

 

I think is more because there aren’t people blowing motors or transmissions with the tune. If you take your truck in because your rear diff is leaking, or a window seal is loose, they have no reason to check if your truck is tuned. They would be looking for mods that could directly effect the parts they are warrantying.

 

I think the word you’re looking for is fraud.

 

Could you elaborate please... I’m not advocating wrongful or criminal deception intended to result in financial or personal gain, rather simply presenting a stock system for repair. Nowhere did I mention fraudulence, sharp practice, cheating, swindling, trickery, artifice, deceit, deception, double-dealing, duplicity, treachery, chicanery, skulduggery, imposture, or embezzlement.

 

You get the stock tune. You can flash back to stock. Been tuned since 2017. Been to the dealer many times no issues

 

Actually that’s exactly what you said, have a failure of a part that’s modified, just return it to stock and go in for repair. That’s fraud no matter how you look at it. You gotta pay to play, if you don’t want warranty issues than don’t modify the truck. Plain and simple.

 

Very limited thinking... your way or your way I see. No one said the modification caused the failure, or try to cheat the warranty...

 

Then why revert back to stock? If the part didn’t cause the failure then Toyota still has to warranty said part. So I see no reason to try to hide modifications if they didn’t cause an issue. We both know what you were implying and that’s fine if that’s how you approach things. I on the other hand fully accept and issue that come up from the medications I have done. I won’t be going back to stock and running to the dealer for something I caused.

 

That skulduggery gets em every time!

 

You must be the last Boy Scout or super religious. I am 100% willing to flash something back to stock if it avoids them denying a power train warranty. Chances are the tune had nothing to do with the failure anyways. We aren't talking about high compression turbo engines or something. The worst a tune could do is lean out the AFR and that's not going to detonate a toyota 3.5.

What if your CPS or some other part failed? Nothing to do with the tune but a great loophole for them to deny warranty coverage.

Toyota dealers aren't benevolent charities, they jam honest people up and take their money unethically all day long.

 

The guy with the burned valves in his engine here had the OVTune, though somehow knew it wasn’t the tune that burned his valves (couldn’t quite figure that out). The other guy with the recent engine 35k failure never answered my question as to whether or not he had tuned. I was hoping for an answer, maybe I missed it.

I would say there is a small amount of risk in tuning these trucks. They main thing is getting the fuel/air mix wrong and in some way cooking the engine over the long term. Maybe that is a sacrifice worth making. I dunno.

 

Link?
I would like to read his words for context.

 

This. Big boy rules.

 

You mean SOME GUY wrote a third party program for an engine that was already programmed by actual Toyota engineers, and like ten zillion dollars were spent in r&d, but this dude bro somehow “made it better” and then some “unintended consequences” happened and people are like “...wut...”


Wut indeed.

 

lol

 

Not for me... I just can’t see the risk outweighing the benefits. Lots of good things said about OVT on this forum, so there must be something to it. For me, just my opinion, had I done sufficient research on the Tacoma (aka found this site first), and discovered that some genius developed a tune for the average person that “fixes” the Tacoma’s drivability... I would of never purchased this truck. After all, who spends $40K on a vehicle knowing you will need to spend another $800 to make it right? With the OVT love here, and the magical results, I would of immediately relealized the stock Tacoma isn’t for me. I kind of felt like the drivability sucked on all three test drives I took before purchase... and that is obviously on me. I’m in it now, needed an open bed truck for a few years... and will ultimately hand down to my son who will definitely love this truck because it’ll be free to him, and more importantly I’ve blocked this site on all his devices... so he won’t be negatively influenced.

 

It’s a long read, but hear you go:

This is what I didn’t quite understand. An overheating engine will not generally cook your valves, but I didn’t feel like arguing. I didn’t really have enough knowledge or info to make any valid points

My question and his response:

 

I adore your use of chicanery. Liked.

 

Ah ok, I remember Trident talking about getting rid of his Taco after a "mechanical issue". He has been tuned as long as I have, maybe longer. No idea about the overheating issue either, the circumstances would be interesting to hear.
Could the tune have caused his burned valves? I can't say either way and neither could anyone else on TW really.
I do know of people who tow regularly with the tune, no issues. If leaning out under heavy load leading to excessive heat buildup is where this is going, wouldn't towing a heavy trailer through the mountains be the acid test? @Shellshock ?

 

What I know (I am not an auto mechanic) is that the fuel plays an important role in cooling the valves, in most normal cars.

I know we have direct-injected vehicles, so there would be no fuel washing over the valves when in direct injection mode with the 3.5L. What I don’t know is if the port injection comes on at some point to cool the valves with fuel under certain high load scenarios.

Someone with more knowledge than me would need to comment on that.
