JustDSM ignoring older customers?

He knows exactly what the deal is. He just doesn't want to assist with it today. As he no longer want to have anything to do with tuning that does not fall into being EPA compliant.
And before you make such assumption. What makes you say because I doesn't know the in and out of how Toyota OEM tuning works. I must be very mechanically inclined.

This type of project was not build by myself alone. Everyone that participate in it have their strong points.
The only thing I base my case on related to the check engine light might be interfering with the transmission not shift to 5th gear. Is because the guy I have access to here that seems to know his ways around this Toyota computer stuff. Says it is highly likely the 2 are related. To the point he claims it.

 

it might be possible to DIY as well.
Knew someone with an engine swapped race car. They tuned it.

that could be a current administration thing not an individual thing.

You see, if we all pop out 12 kids and abandon them
Tear down all the trees

and all of us drop $40k on a Tesla delivered by diesel and made by stripping the earth

planet will become magical

 

Are the O2 sensors plugged in, or not plugged in?

 

The rear 02s were not plugged in originally, as I was under the assumption they had been deleted. Then I installed them after having come across a electric drawing on how to solder in a resistor and capacitors to each sensor that was supposed to become able to bluff the computer into believing the cat was in place and working as intended. ( O2 simulators )
But that did not work out as I was hoping and the check engine light remains and no 5th gear upshift

 

Just buy the HPTuners and the 4 credits and uncheck the box for monitoring rear O2 sensors. You don’t need to be a tuner to do that.

That said, it’ll only disable your CEL, but I don’t think it’ll solve your shifting issue. The downstream/rear O2 sensors AFAIK have no effect on drivability.

 

I'm not assuming; I'm stating that he offered to disclose all communication, where you haven't given any evidence that "he knows what the deal is," so that makes it appear the way it appears. Its not me picking sides, just saying what it looks like. For all the people flaming you, I'm one of the few excited to see your build succeed, so I've exercised caution from jumping on the bandwagon and dismissing everything you have to say. Its not all the time, but companies and individuals do make mistakes, so I hear what you're saying and would love to believe you, but you've gotta give me a reason to. That being said, I don't think its completely out of the equation that Justin "may or may not have" agreed to design a tune to accomplish your goals, long before he made a business decision to go CARB/EPA compliant, and 2 years later is deciding he's not touching it with a 10 ft stick. I wouldn't blame him either (if thats even the case).

As for assuming you were somewhat mechanically inclined, maybe I was wrong to think someone building a truck on 44's and SAS by themselves (according to your own words) was fluent in mechanical knowledge. It makes more sense now knowing that many people have had their hands in your build that something could (and did) go wrong. At the end of the day, if you don't know the right questions to ask, its going to be extremely hard to help. While I can't offer much help, I'd still love to see your build succeed.

there's probably no doubt the 2 problems are very related. but considering you DIY'd some stuff to "trick" the tuned ECU, if I was a tuner, I wouldn't touch it with a 10 ft pole either. Sounds like you need to find cats, O2 sensors, and do some troubleshooting to ensure your issue is actually what you think your issue is. If you can get it to work properly, THEN try to find a catless solution. We understand you're frustrated; but you're building a supercharged SAS'd truck on 44's; its not supposed to be easy, so don't blame your tuner.

 

A single epa fine can put a tuner out of business so nobody will touch that stuff, good news is hptuners is a super easy program to use for anyone familiar with tuning software and judging by the number of Toyotas in Iceland on tires that cost more than my house I’d bet you could find someone to help with your issue locally

 

To begin with I was originally only asking if other "older" customers might have experienced similar reaction on his behalf. After he become the "legal guy."

I was not really asking any of you guys for advice what was the cause for my issues .

The reason I did not provided more info originally was not to cast potentially a bad light on other USA based company that at the time provided me with a catless exhaust system.

As for saying I had build the vehicle myself. I was just trying to not add unnecessary words to my message. Most people know that have done anything on such a level it is never a one man job.

And lastly.
As I have stated before Justin was well aware what type of exhaust setup I would be running. So having not turned of the rear 02 at the time. Made no sense.
So I stand by my case. He didn't provide me with the right tune for my application. And the only thing I am asking/expecting of him. Is to do what he was asked to do ( and agree to at the time)

That is all folks!
I guess this tread is not going in the direction I was hoping. And not really surprised either as I know he is a good tuner and has lot of fan boys and happy customers. But in my case at least, he didn't to all of what I assumed I had been paying him for. And he is unwilling to make it right ( for my application) But that I guess is how live goes these days.

Thanks to the guys that at least were willing to see it from my perspective.

 

The tune file is locked and unless Justin will provide me with a unlocked file ( that he won't) the guy over here can't do anything with it ( HP tuners credit or not)
My only option seem to start fresh with a inexperienced tuner.

 

I don’t want to get in the middle of your spat with Justin, but some of us have posted suggestions how you can overcome your issue and move on from this impasse you’re at now. I’d you just bite the bullet and disable the rear cat monitoring yourself, then you will still get to enjoy the actual tune from Justin, which is probably very good.

For what it’s worth, this is exactly what I have done.

 

I don’t think any parameters can be changed if his file is locked, he’s going to have to get flashed back to stock and start over with another tuner

 

Did you try taking the resistors that you added, out of the sensors, and putting it back to normal?

 

OK, care to share how I should go about disable the rear cat monitoring myself? ( Rather care for a DM? )

I have at least tried the trick of fooling the sensor with this "O2 simulator" electric drawing I got without success

 

No I have not, maybe that is worth a try. But I just assume ( and still do) it won't turn of the check engine ( because there is no cat ) and there for not allow it to shift up to 5th
( based of what I have been told by my local computer guy at least)

Thanks for this idea.

 

you could also try removing the resistors and adding a spacer to the secondary o2, I’ve seen people with catless headers on here have some luck with that method

 

I've got no dog in this fight and I'm not taking sides. I just want to thank @JustDSM for reminding me why I didn't go into business for myself years ago. I was constantly asked to go into the home 'handyman' business by friends because I was seemingly able to fix anything. I just don't have the stomach for the drama. Peace and Love.

 

Maybe try some smaller wheels/tires and see if the transmission behaves better?

 

What are the warranty provisions in your original purchase agreement?

 

"original purchase agreement"
I don't recall it was this formal. he just provided me with a tune for my application based of the part list I provided him with. And I paid the man using PayPal I believe. This was all done just through the DM's on here.

 

someone else asked but you did not respond - what axles and gearing are you running now ?
