I dunno; it's just a weird situation and it might resolve (between them, that is; his job keeps him away from home life a lot sometimes and Mom's had enough). Dad's so fiercely independent, and he hates feeling like a failure, I agree he shouldn't be ashamed or secretive or whatever but I guess he wants to keep the problem under wraps until it's a sure thing.

Just tell her if she's edged cause he's weasing on her grindage, just chill, cause if he had the whole brady bunch thing happening at his pad, he'd go grind over there, so don't tax his gig so hard-core cruster.

Beach Bum: sounds like you both need to work on communication; you being weird and evasive about your dad’s situation probably didn’t help, but her lack of understanding (I mean c’mon - it’s your parent) also sucks. Side note, you’re not in college, “roommate” has juvenile implications, probably better to phrase that differently to any/all.

With that said I’m astounded that she doesn’t contribute to the mortgage unless that’s how you see the $200/mo. This person sounds coddled.

The dog thing is also dumb considering she has to know you have a dog, and that said dog needs help? Moving in together and adopting cats all in a 6 month period are yellow flags at best. This kind of drama may well be portents of things to come IMO. :( I sense a lack of empathy and an increased sense of narcissism on her part, and you may be an enabler. Consider counseling/therapy, or maybe just :sever: as none of this will just get better on its own, you’ll need effort from both parties.

Yeah, but she doesn't even know it's his dad. I feel like if you're dating and living with this person, she has a right to know this stuff. I'd be bothered as hell if my GF said "someone might need to live with us for a while and I can't tell you who." Like, if you don't trust her to not go out and tell everyone about it, you shouldn't be dating or living with her.

Edit: to be honest, 3 months is way too soon to move in together. You're still treating her like a roommate instead of a partner and she doesn't appreciate it.

Combination of what's already been posted. This doesn't sound like a good situation, and her being young/poor/whatever and not having another place to go she could feel a little trapped without much control of her situation. You have to be up front and communicate if you expect any of this to work out. It sounds like a touchy situation with the work aspect but this is your partner, not a roommate. If you can't trust her with this info (to keep quiet about it) then there are probably deeper issues.

The dog thing is probably just her already being pissed in the first place and just one more thing to be mad about. Resolve problem one first and deal with this later, IMO.

To an extent, neither of them have any say here. Your communication to the GF shouldn't have been any more than "my dad is coming to stay for a while and I'm bringing my dog home", and your dad cannot reasonably expect you to keep someone WHO WILL BE IN THE loving HOUSE WITH HIM from knowing what is going on.

I guess I hadn’t picked up that Beach Bum STILL hadn’t told his GF the “roommate” is dad.

Life lesson for Beach Bum: if you’re living with someone and sleeping with them, honest and open communication with them trumps whatever reason for confidentiality you think you need to carry with your dad.

If you still can’t bring yourself to be open and honest with said person,

1) you probably shouldn’t be with them,
2) you need to work on your own poo poo so you can have mature relationships, and
3) you need to make sure your dad understands those boundaries, and if he doesn’t, set them

Put yourself in your GF’s shoes - if the tables were turned and you were living with her and it was her mom that was moving in but you didn’t know that - leaving you to think her ex-boyfriend or someone is moving in as a “roommate” - you would be 10x weirded out by the whole thing.

BB, if I were in your GF’s shoes “hey we might be getting a new roommate but I can’t tell you who it is, I’m going to work now kbye!” would definitely upset me more than “hey my mom and dad are splitting up and he might need to crash with us until he finds a place, are you OK with that?” I’m sure your GF would respect his privacy if you asked, it’s inevitable that she’s going to find out what’s going on if/when he moves in with you so keeping it a secret is just going to make things unnecessarily weird.

She might not pay any of the mortgage but having gone through a similar situation recently (hosting a recently single close friend of my partner’s until he could find a new place) it’s a stressful situation even if you’re all in the loop about what’s going on. If you guys are at the point where you’re saying “I love you” and living together she deserves transparency even if she doesn’t get veto power.

I agree with this a lot.

You have more than a "housemate" in your SO at this point. The way expenses are tied up are completely irrelevant and pulling rank by saying "I make more money and spend on our housing than you do" will end your relationship. You share your dwelling, full stop. My wife hasn't worked in over seven years and I wouldn't dare ever trying something like that. Your dad should be completely understanding that "you aren't telling anyone" means that you don't tell anyone outside of your house. My wife and I tell each other everything because we are mature adults and understand that things told in confidence are meant to be kept in confidence and we are united together. When friends/neighbors/family say "don't tell anyone" to one of us, they know full well that the other person in the marriage will also be told but that it will be kept in confidence.

Rethink the whole situation and think about how if you approached it differently. If you came outright and said "Hey, SHTF for my parents marriage and I am concerned Dad might not have a place immediately following the fall out. We (Editors note: not "I") have a spare room. If I help you get it a little sorted and organized do you think it would be okay if he stays here until he figures out housing?"

You could then go into specifics about what kind of duration you anticipate so you have a plan. Your dad should be involved in that discussion as well barring an agreement with your SO.

I have a 2K sqft basement with two guest rooms, bathroom, etc that we fully have set up for the expectation that either my parents or my wife's parents stay literally whenever they need. It is an open invitation to either of them, they have access to the house etc but my wife and I always clear it with one another before committing the "okay" with our parents because we respect that we both have equal say.

This.

And: some dog people just don't know they're dog people yet. My wife finally cajoled me into getting my first dog 6 years ago and I sometimes get a little weepy just thinking about all of the dog love I missed in the previous 34 years of my life.

And: when you are in a position of power, reminding somebody of that position ("you get a say when you have an ownership interest in the house") is antagonistic at best. That may be true, but saying it is unkind. Yes, you have approached this situation with logic. But you have not approached it with kindness or emotional sensitivity. That's a hard skill to learn but is a 100% predictor of relationship health.

Try this on for size: knowing that you have the power in the situation - you could, after all, break up with her and kick her out into the street - would it actually hurt you to make her feel like a part of the decision by making it a question? "Hon, this is family stuff and so just between you and I, but it looks like my dad might need to move out and he doesn't know where to go right now. Do you think we could put him up here in the spare room for a bit to take some pressure off of him?" If she says no, maybe there's a good reason, and maybe that's a good conversation. But if it's a no with no good reason, you still have all the power in this situation.

Now imagine being in her shoes and knowing everything above. She can't say no. She isn't being consulted, but if she pushes back, she could be homeless.

1. Be kind to people, it's just the right thing to do. Sometimes they'll really surprise you.
2. Object lesson: this is privilege. Be careful with it, it's a weapon even if you don't intend to use it so.

I'm pretty sure a device communicating with a vehicle's CANbus over the OBD2 port is at no disadvantage versus other devices on the bus - CAN in theory has a 1 mbit/s limit and gauge clusters themselves are often directly consuming CANbus data for display.

What can sometimes be harder to deal with is decoding which PIDs represent what data, and what scale the values are on.

All the retail stuff I've found (so far) to work with analog sensors starts at about $1K, and still doesn't offer the kind of customization as far as the layouts and style as that SIM Dashboard.

I mean, I can use discrete electronic gauges, sure, but it really seems like, in 2019, I should be able to put a single display in the car, and drive it with whatever gauges, colors, or layout I want, like the newer Vettes, Hellcat, etc.

With the right tools, this is easy for basic signals at least. Did some of this when I was green(er) doing competitive testing. :) What is difficult also is that not everything is mandated to be streamed to the ALDL, and more and more parameters are added every year at an exponential rate. Oh, and the manufacturers that have separate diagnostic ports hidden away under panels that we needed to use because they were less secure with generic (AKA not their manufacturer) tools.

The rate thing bugs me because I was used to 100 hz for anything I wanted in previous work, so 5-10 hz looks like garbage in comparison. :v:

Except the sampling rate over OBD2 is much slower than interfacing directly with the bus. And the more PIDs you're checking, the slower the refresh gets.

10 hZ (best case) is a bit too slow for stuff like a tach, and the more stuff you're pulling data for, the slower it gets. Hell the factory tach on my car is laggy enough, and it's tied directly into the bus. Comparing directly interfacing with the bus to capturing data using the generic OBD2 protocol is like comparing 6mbit DSL to a 2400 bps dialup BBS.

There's ways to directly interface with the bus over the OBD2 port, but you need something that speaks the car's native tongue instead of the generic OBD2 protocols. That's not gonna be as cheap or easy.

About a month ago, I asked my friend to come over with his Tacoma to help me get rid of a mattress and box spring, and we could NOT get his tailgate to open, so we had to gently caress around worming our arms under the tonneau cover to get it rolled up.

Last weekend he borrowed his step-dad's chainsaw to help his wife's grandpa clear some trees out of his property. On the way home, the tailgate popped open and the chainsaw slid out of the bed :v:

:golfclap:

I wanted to get some more stuff moved today. Sprayed graphite in the lock. No good, it still locks, I can still open the glass part (which slams into the top of my dome about 10 seconds after letting go of it, natch), but I can't unlock the hatch. Stuck my head in and found an access panel dead center in the middle. It looks like it's to get to the license plate lights, but I was able to find the rod going to the lock cylinder. Popped it open easily. That cover is staying off until I can get a copy of the key she uses every day. The key I use sometimes has issues with the passenger side door too (it'll lock, but not unlock).

And if you ever wondered if you cat fit a Lay-Z-Boy recliner in a Matrix and fully close the hatch... yes you can. Have to angle it a little to get it to completely clear the opening, but it fit with plenty of room to spare. And now the car smells like hantavirus. :barf:

OBD2 in practice is a standard, not a protocol. There’s 5+? widely used protocols that can run over the port/bus, and CANbus can talk at 250-500kbit/s. Virtually all cars over the past 10 years speak some form of CAN.

Edit, more info:

Wikipedia posted:

ISO 15765 CAN (250 kbit/s or 500 kbit/s). The CAN protocol was developed by Bosch for automotive and industrial control. Unlike other OBD protocols, variants are widely used outside of the automotive industry. While it did not meet the OBD-II requirements for U.S. vehicles prior to 2003, as of 2008 all vehicles sold in the US are required to implement CAN as one of their signaling protocols.

pin 6: CAN High
pin 14: CAN Low
CANH signal voltage level: 3.5V (min/max 2.75 to 4.50)
CANL signal voltage level: 1.5V (min/max 0.5 to 2.25)

All OBD-II pinouts use the same connector, but different pins are used with the exception of pin 4 (battery ground) and pin 16 (battery positive).

I also found sources indicating CAN can transmit 1mbit/s, so in no way are you going to saturate the bus even doing 1-10ms update/refresh cycle, multi-byte messages to a speedo and tach.

I'm aware of that, but many of them are significantly slower when communicating with one of the several OBD2 protocols instead of the manufacturer-specific protocol.

And CAN dates back to 1992 for automotive use; GM and Mercedes were the first to use it. GM's implementation, at least in the late 00s, uses a whopping 10.4 Kbps for stuff that doesn't need the high speed bus (the PCM and other critical components communicate with each other at ~500 Kbps).

I'm not saying the CAN bus itself isn't speedy - it's plenty fast for what it is. But speed goes to poo poo when you're using one of the generic OBD2 protocols instead of a manufacturer specific protocol. The whole reason this came up was implementing aftermarket gauges; any that actually do tie into the existing vehicle electronics will likely do so via a generic OBD2 protocol.

OBD2 ports were required on all US cars from 1996 onward, and I think the original OBD2 standard was ISO 9141, but there's been 4+ standards just used in the US that communicate over the physical port, using different wires, as none of the standards have ever utilized all wires available on the OBD2 port.

In 1996, no car used ISO 15745-4 CAN on the OBD2 port as I don't think it existed as an ISO standard at that point even if Bosch (may) have already designed it, or at the very least an earlier revision of CAN. The US Gov't didn't require any CAN to be available on the OBD2 port until it adopted ISO 15765-4 CAN as the standard that would ultimately be required by 2008; some manufacturers started providing ISO 15765-4 on the OBD2 port as early as 2003, but it was required from 2008 onward.

GM in the 1990s was using the Class-2 Bus - not CAN - and conforming to SAE J1850 VPW (variable pulse-width) which is and was limited to 10.4 KB/s. They may have also still supported ISO 9141 for backward compatibility on the OBD2 port itself for pulling OBD2 fault codes, but I'm not 100% on that.

Prior to ISO 15765-4 being required as an industry-wide standard, GM designed and switched to using GMLAN as a communications format running over the CAN network, but in a transition period (~2000-2007?) often or always, not sure, did not support ISO 15765-4 on the OBD2 port, still providing SAE J1850 VPW. Meanwhile Ford in the early 00s was doing their own thing and decided to use SAE J1850 PWM (pulse-width modulation) which could run something like 40 KB/s on their cars.

All these different standards could still provide OBD2 PIDs, but at differing rates, on different wires, via different communication methods. So yes, your old cars are transmitting information over the equivalent of a POTS copper telephone line at 2400 bps, but as of 2003 onward, some manufacturers were using the equivalent of DSL modems over the same infrastructure to transmit the same information and more over a different digital bus at 250-500 kbit/s, and everyone was by 2008.

In a car from 2008+ onward, you're guaranteed that it's going to support ISO 15765 CAN, and that's going to be available on the OBD2 port because ultimately all the different standards use different pins so adding new standards hasn't negatively impacted previous standards. Even a $10 ELM327 Chinesium dongle off Amazon supports 500 kbit/s CAN so long as the manufacturer added the right pins and/or the ripoff chip in it isn't hobbled.

A good visualization of the different pins used by the different standards:


Edit: one more analogy for you; for cars that support ISO 15765 CAN, think of the OBD2 port as not just where you can pull OBD2 trouble/fault codes, but a network jack that lets you get on the Car Wide Web via CANBus and, with a CAN-compatible device, you can either be a passive listener to the data flowing over the bus (gauges) or transmit your own data to other devices on the bus (ECM, BCM, TCM, etc etc.)

Before the forced adoption of ISO 15765 by 2008, yes, different manufacturers were using their expensive and proprietary scan tools to be able to update their own cars and run diagnostics or control different computers in their cars - but they were still ultimately doing so (with a few minor exceptions) using the same wiring and conforming to one of the 4 standards that an emissions testing center could pull OBD2 PIDs on demand from.

edit: part of my problem is that the factory gauges in my Cutlass didn't have all the useful gauges like oil pressure and coolant temp, or even tach. There was a factory option, but it's pricey (look up 1970 Cutlass "tick tock tach" or "Rallye gauges".) I have three ~4" gauge locations, so I'd need a tach in one, speedo in one, and then a combo gauge in the third. It's that 4" combo gauge that's tough to find, though I bet Dakota Digital or someone could build me a custom face if I shat $$.

There's a pretty insane cluster build that Sagebrush did for his old Honda Hawk somewhere in CA, the end product looks like cover art for Gunship, tons of tech links and whatnot in the post that might be a good jumping-off point for building something yourself, there's so many little electronic doodads available nowadays a lot of electronics poo poo is pretty easy, and you can avoid a lot of the programming by buying electrical gubbins that work without being wrung through an Arduino first, if you want to cheat, I whipped up this "magic" box as a sensory toy for my nephew in a out an hour.


There's a lot of really solid relationship advice going on in this thread, I own the house I live in, and I still let my roomates (married couple) know when my gf is coming over, and I always phrase it politely, ask if they "mind" and it's been almost every weekend for months. People, especially those who are constrained by situation or finance, like to at least have the feeling that they have some amount of control over it, and it's never a bad idea to find a more polite way to break news to someone, even, or especially, if the ultimate card that you're going to play is "get out of MY house" which is the one I'd personally use if my GF of 6ish months took a hard stand against any of my family moving in.

Weird. My wife insists I deliberately turn the traction control off, but then again she does give the warboys V8 salute to the M3 every time we go out to it from wherever we're parked at...

Your wife sounds cool. :)


Did the fluids in Vic today pending road trip tomorrow, and I adore working on something that big. Everything's well clearanced except the rear spark plugs.

She is pretty cool. The fact that she's owned more fun cars (two Mk1 MR2's - one with RHD and one with LHD, a couple Fox Body Mustangs, a vintage Rolls) than I have isn't a bad thing either.

She's also 5'9, has a very middle-english british accent with the edges rubbed off from being a Lancashire lass educated at Oxford, and enjoys watching me play shooter video games (poorly). I can't complain - I've done okay for a no-account chancer from Iowa..

I've been watching prices climb on 240s for a while now. Maybe 3 years ago you could pick them up in decent condition for well under a grand and now they're all at least 2 grand.

I bet more. Clean CRXs were picked over a decade ago. Fun car at the time, pretty much defined the segment. I wouldn't be surprised with $25k+

Edit: speaking of deals, one of you guys buy this, put it on BaT, then reap major profit. I don't have the time right now.
