JustDSM ignoring older customers?

OTT is my direct competitor and as everyone has noticed, things tend to get..."aggressive" at times, but to be honest, I hear your concerns and see the issue in it but in regards to the shifting concern, I don't honestly think this is a tune issue but most likely the ecm seeing too high a load to allow further upshifting. I don't know if the software can overcome that even with a supercharger.

Unless you specifically wanted the check engine light "bypassed" for your stated concerns and was promised that it was possible, I also don't think the tune has an effect there either. Modern vehicles are more sophisticated in their downstream monitoring as in it'll purposefully and randomly try to peg the sensor rich or lean momentarily to ensure it's reading correctly so a sensor fouler doesn't tend to work on things newer than 07' on average. A tune also doesn't change the diagnostic parameters, especially in regards to emissions components.

In conclusion, OTT is my direct competitor but I honestly have to lean in @JustDSM 's direction here based on the information provided

 

Downstream O2 sensors don't affect engine operation usually, they're just for monitoring the catalytic converter to ensure it's working.

Have you looking into what the issue is with circuit, like is it shorted, broken wire, unplugged connector?

I'm not a Toyota guy but I am a Red Seal Mechanic

 

OP, 2 years ago (when you bought the tune). You could buy o2 simulators. You can not buy them now. The EPA has issued massive fines to those making, selling, or modifying a “defeat device”.
You don’t recover from those fines. You close up shop and hope you have a home to go back too.

My best advice is to not talk about what you are trying to do. And find someone else that “doesn’t talk about it either”.

Or………..put the cats back on and “fix” the issue.

No need. He has no cats.

 

In addition, using HP Tuner to build and modify your tune forces and signing of training and certification of the EPA equipment. If you are in a different country (Iceland) that does not require those standards then you would probably need to find a local tuner. Or you could purchase the HP Tuner and credits then do whatever you wish.

However, Justin is more than upfront with people. I wasn’t in your conversation but assuming a parts list denotes you are clearly in violation of the law he is adhered to abide by is a very poor assumption. Even in regards to off-road only utilization or other countries isn’t worth the risk.

Catless headers seems like you are trying to delete A/F sensors and not simulate O2 sensor.

 

As I stated originally I wished it wouldn't have to come to this making a public tread about this. But both his attitude regarding my inquire and lack of respond. Eventually got me ignored enough to go and ask if others had been experience anything similar.

In my understanding the rear 02 monitoring can be delete from the ECU.
But at this point I have lost all hope Justin will do anything for me.
So I guess I will just end up having to allow this local guy we have over here to see what he can do for me.

I will keep you guys posted if swapping in the ECU that the truck came with will manage to sort out also the issue with shifting up to 5th gear.

This is a 2005 Tacoma so we shouldn't have to deal with any additional emissions related issue with 2007 or newer vehicles might have.

 

I would probably tend to agree with you, so I'd reach out directly to the tuner for clarification, which it sounds like you did and had communication as recent as of about 7 business days ago. I'm still not completely understanding if this was a commitment from him for a tune 2 years ago that he can no longer provide due to legal requirements that have changed within the last 2 years, or if even 2 years ago he had no intention to meet the O2 delete requirement and you didn't realize until 2 years later. Without the full context, which he seems willing to give, it sounds like you're under the impression the 1st is the case, and he's under the impression the 2nd is the case. Maybe I'm wrong, but it sounds like he's not convinced the transmission issue is in any way related to the tune, and you're fully convinced it is. What have you done in the meantime to fully diagnose it? It truly sounds to me like you're very mechanically inclined to build something like this - why not swap parts temporarily to confirm whether your statements are true or not. I'd have to imagine he'd be willing to work with you (whether you achieve the original goal or not) if you truly proved his tune was faulty. The 2 year gap definitely complicates things, but giving him some true data to work with goes a long way as far as getting some real help goes.

 

InB4 LS swap (that's what every built Toyota with 44" tires use right?)

 

44s?

And he's wondering why it won't go into OD?

 

^I'm just guessing whatever one-ton axles he's using are geared appropriately...

 

... reminds me of the 2013 arctic hilux they have at the LC Museum in SLC -- definitely worth a visit. Cool audio that you can hear on the page. https://landcruiserhm.com/museum-collection/vehicle-collection/202-2013-hilux

44x18.5x15 haha

 

Asking to disable the Rear O2 is enough for me brother

 

I don’t get it.

someone else likely untuned just made a thread asking for help. The consensus was they have bad O2 sensor(s) causing limp mode, slow shift, etc
So what if you’re having that

can a tune code out rear O2? For reasons, that’s a rhetorical question I don’t want to know the answer to.

you need to find out your emissions regulations which includes what state you’re in.

and if that’s what you’ve having a problem with start there.
Make sure your sensors are good. O2 sensors can go bad.
Make sure your cats work.
I heard early models basically monitor main cat not secondary.

other things like spacers for any kind of vehicle have been around for a while with reports that some work while some don’t. That’s a hardware thing.

beyond that I don’t know what to tell you.

would I ever make this truck zero cats at all straight piped even if I could? Probably not.
1. Don’t need rotten egg smell behind me
2. I don’t need a stupid sound

what exhaust you run might make a difference. supposedly there are some decent HFC’s out there that still filter. Whether it comes for the truck or standalone to weld.

 

rotten egg smell comes from the cats
not from running catless

 

@OP, you can try and find someone else to get you the tune you're looking for, or install the cats with O2's back in.

No, I haven't had any negative experiences with Justin, nor have I heard of any. I just know he's very busy with his services. In my dealings with Justin, it was clear what I expected of him and what he'd provide prior to payment. FWIW, I hope you find resolution to your issue.

 

OP is not located in the USA.

It doesn't matter if they are good, he has no cats

They don't. There are none.

 

@JustDSM doesn't ignore older customers. He has always been timely with my needs and I am a happy customer.

 

No need to continue with this thread.
Justin made it clear he isn't interested in discussing turning off the CEL.
I don't blame him, I wouldn't either.
OTT isn't made up of only Justin. There are others involved too.
Too much to loose. Even more so when the other party is heavily modified and in a whole different country.
Not to mention, 2 years ago.

Sorry OP. You're better off finding a local guy that has the time to work with you.
Your issues don't sound like they are easily fixed by a single tune. It may take a few dyno runs and data logs before you finally get it figured out.
And that's where a "local guy" would be a much better choice.

Best of luck to you man. Hope you get it figured out.

 

Happy old customer. Op broke the first rule in Fight Club.

 

don’t know about you but
A tune anywhere you go costs what it costs

if years later I needed additional work. Custom shit whatever.
Me personally I’d be offering to pay something not expect things for free. Because I think that is how life works. Nothing is free.
And give reasonable amount of time to work with party. This is life. Emails fail to come in automatically filtered out. People forget shit. Everyone.


time is money and people have bills to pay.
If I go anywhere with nothing. And offer nothing. Then I would expect nothing.

I am not interested in immediate results, having people drop other things, or lighting fires. with anything. And if that’s ever not understood then well shit.
nobody who is worth a shit at anything they do is usually available on a one second basis.
It goes both ways. Been on the receiving end. World doesn’t revolve around person.
In a correct scenario, if I am hit up about a job, I am in the middle of another job. That is efficiency.

you want quick go downtown knock on a tent ask for brown smear on window that’s your quick quality right there.

 

@Trooper99 I think Justin made it pretty clear that he's not willing to do what you want. Whether he made a commitment or not to do it 2 years ago, you haven't really given us any good evidence that he did, so its hard for anyone to believe. To most, it just looks like you're experiencing issues 2 years later, are frustrated, and looking for someone to blame. Not saying thats the case, but considering Justin is willing to disclose all communication to save face, thats the way it appears. You're more than welcome to provide any credible evidence that says otherwise if you feel the need. But because this threads going nowhere, and I believe your circumstances (not having it up and going until 2 years later complicating things from a "warranty/troubleshooting" perspective) are just unfortunate and probably could've been resolved 2 years ago, I think seeking out another tuner is going to be your only bet to accomplish whatever goals you're trying to accomplish. Admittedly, I'm not very knowledgeable in the realm of tuning/mechanical knowledge, but I'd imagine what you're trying to do is probably possible - its just a matter of finding someone who will do it. Post some threads, ask some questions, but don't get discouraged if your plans for the truck have to change. Sadly, its the world we live in, and in certain places, tuners' hands are completely tied if they want to keep their businesses up and going, having to abide by certain things. It honestly sounds like you could really benefit from getting all the resources to do tuning yourself, and asking someone really knowledgeable all the right questions; like "how NOT to do what you're trying to do." To stay compliant, of course. Your truck sounds like a badass build, I'd love to see you accomplish your goals and get this resolved with someone else.
