Gen2 OBD2 app review | Page 10 | PriusChat
I'm down, depending on if offered the feature option to remove my contributed data from public access and or removed from the public facing server and server backup system.

see I've already been there and been refused access to my contributions. Now I'm more than a little burned by the admins motus operandi, after the server was taken over by a large group of admins that was originally a single server under one developer server desk, in the EU. + other unsavory unresolved old issue(s) from the staff during that time period.

absolutely lovin the current state of more than a few things on my plate currently

 

It's not running well... hence my earlier post:
2009 Prius Techstream Data Log Request | Running at its best? | PriusChat
Since making that post (which I should update), I've replaced coils, spark plugs, injectors, the MAF sensor, and the lower oxygen sensor. When running Techstream alongside two separate OBD2 dongles connected to different phones simultaneously, all data aligns perfectly across each setup.
I've also run my collected logs through my local AI system—yes, my Prius houses a mini gaming PC that's soon getting an upgrade with one of those new AI CPUs and an Nvidia GPU. My analysis points toward the HV battery as the root of my current issues. Additionally, I'm suspecting my Ali CAT took a hit after bottoming out during some pre-lift tests; there's a noticeable rattle now. I'm currently working on sourcing a California-compliant catalytic converter resembling a Magnaflow CAT.
Regarding Hybrid Assistant—yes, I understand it's free. However, it would've been better if they'd conformed the export data to an industry-standard OBD2 vehicle log format rather than their current approach, which, if memory serves correctly, seems to utilize some odd variant of MySQL that's not widely used, at least in my circles. I'm puzzled why they didn't just export to a DBC (CAN Database) file, considering many corporate-grade applications can easily import and process DBC files into visually appealing, easily searchable reports and graphs. As it stands now, I haven't yet managed to visualize their exported data the way I'd like, though soon, I'll have an AI-powered supercomputer handling the heavy lifting of parsing through gigabytes of vehicle log data.
Gen 2 is indeed an intriguing nut to crack—but rest assured, there's nothing I can't tackle when I set my mind to it!

This is exactly what I'm looking for—some data from someone whose Gen 2 is running at tip-top shape.

So now, where can I find all pages of this report in a single document?

roger that ghost rider!

Most definitely—there will be a link anyone can click to have their data fully removed.

As for having a full plate, the hope is that by EOY 2025, in just a few weeks here, things start to finalize and the plate clears.

I had a particularly passionate "fan" put considerable effort into, uh, let's say, "encouraging" me to halt my progress. While he didn't succeed, he significantly slowed things down. But that's alright because I genuinely believe the universe always rewards those who remain righteous and do good. That said, when I release what's been cooking over the next few months, everyone will clearly see how spectacularly wrong all these Negative Nancys have been about me and my company!

I used to get that a lot too, even from customers who I went out of my way for, like Jack does, or at least used to. I'd be surprised if Jack still does after the "where there's magic smoke, there's fire" ! ! - even if there never ways a fire in the first place.

I write people off my Nice list a lot easier now than I used to.

 

You know… don’t lose your compassion or your positive outlook. I never did. Yeah, I might not jump to be all buddy-buddy with every new message in my inbox like I used to—but I haven’t let the disappointments change who I am at my core. Funny how the people you bend over backwards for are often the first ones to try and scorch you when things don’t go their way. But here’s the beauty of it all: the truth always comes out.

Eventually, folks who bought into the noise—especially from non-customers—will realize just how foolish it was to believe the nonsense. When they finally understand what really caused the delays, things will start to make sense.

Not trying to derail the thread, but I know people watch what I say real closely… so I like dropping my thoughts into these little internet watering holes. It's therapeutic.

 

I hear ya, me either, it just happens some times when we forget what the Title of the OP is. It's not uncommon at this forum, and how annoying to the OP probably depends on how thick a skin. I hope @mr_guy_mann is not annoyed too much yet by our departure for the OP theme.

Besides and this is just my take on threads that can span many pages, it's can be hard to both keep them current and still relevant to older car owners with sometimes older host devices, whether or not those devices get updates to either the app in question or the OS. for example
Does anyone have the original Autel Maxi2000 app for Gen2s? | PriusChat

Which I saw yesterday in the Gen 2 section (still with only the OP showing) before Tideland merge made it's way to the that OP.

I took a look quick look for possible old versions of the app, since what I imagined after reading that he was asking for was an old version of the Autel Maxi3000 app, that used to work on his device but the updated Maxi3000 app doesn't.

That kind of illustrates ( for me anyways ) at least some of the problems keeping older apps and host devices functional well past their use by dates. Not old school use by dates but typical current use by dates of when it stops working buy a newer fancier one that does work if you haven't already got at least one of our latest and greatest ( innovations )? ....

 

very very good point that I didn't even think about! well, all I know is I was on the hunt to edit the ECU via the OBD2 port and in my quest there I tried many devices. Some even would throw the check PPCS error on my Gen 3 PIP(these were the really cheaply made internal boards) but then on some site vehicle manufactures dont want people to know about hosting not in the USA I realized I needed to directly access the chip on the ECU and thats how I got there. But.. even when it comes to using Techstream, the older versions depending on USB cable have always worked the best.

But.. I need to take the time to properly test per the INF code triggers discussed earlier.

 

Which reminds me of a tube I was looking for by AMD on his car care nut channel about the Prime 2022 refresh showing the 2020 with the back seats removed ( which I haven't found yet - he's got so many ).
I did see another while searching ( ( think iirc it was one of his ) About a dealer throwing the parts cannon at a car .... which is funny unless it's one of our cars that we are firing the cannon at.
Going to see if I can find it again now. wish me luck ....
edit: it was an easy find and it has relevance to Gen 2 ( if Gen 2 Prius ) include the Bean network and Gateway ECU.
youtu.be/itiwqKYlONA

Now he's talking about the ABC network for the nav. I only read about Bean and Gateway yesterday here. The ABC network is a first for me.

 

No, he really is looking for the original Max2000 app.

It's the AVC network, not the ABC network.

I don't know how the OP feels about it but I for one would appreciate keeping the thread on topic.

If you don't have relevant Gen 2 information, it's best just to say nothing.

 

I pulled the two units out of the dash of this Gen 2 and have an android head unit working for audio and steering controls, its the indicators for say low coolant or other vehicle specific indicators that shows on the MFD thats missing. But right now specifically its the air conditioning controls as I was able to figure out how to toogle the controls on the screen, just getting them to work to the touch or being able to see changes on the screen when the steering wheel climate controls are pressed is what Ive yet to overcome. I told myself to reverse engineer the wiring diagram to see which wires go where to then see what wires the harness has and how they correlate to the system. Getting rid of the brain under the drivers seat is my goal with getting all this to work and having a Tesla style screen finally installed. I just know now after building a Gen 2 how important it is to have a screen return all values we might get on the oem MFD...

how's the above for related to the Gen 2 and OBD2? If i get this right, I want to be able to use the Tesla screen to see INF codes since the OBDs connector is already going to the CanH and CanL... in theory, its easy and can be done! that said... I love how so many can correct others and the simplest thing such as even a synonym... yet, all these smart folks around here and to date I am the only one whose gotten as close as I have to replacing the mfd and lower radio with a Tesla screen... I would've suspected this community to have been further along. Oh well, ill lead then as it appears most hide behind "basic logic" and assumptions while being timid to try something new.

 

apologies @mr_guy_man and other Gen 2 owners.

I was trying to contribute Gen 2 relevant things, even when posts may have read like they only related to other diagnostics.

 

interesting observation here, while running bluestacks on my pc the other day, I thought "well, if they want to use the autel so bad, they could install the older app on bluestacks and bluetooth connect the hosting machine to the obd2 dongle". then today coming back here I did a quick search and sure enough, that's what folks are doing to use the older software. this way, you can run an older android and the older software and be solid. Android 10 it sounds like would be the preferred version as a few mentioned with the Android 11 update things got wonky. going that far, might as well dive into the esp32 world of odb2 like those people use to get their strikers. I mean in theory, that's the only way to steal a Prius, get in, reset immobilizer and pair new key fob. but since Prius no go into neutral without power and fob, you cant use a skat pack to push it where you can sit to do the re keying process.
