What did you do to your MKIV today?

can't take bugs when golfing

True, but three whales make a pod, 3 crows make a murder, and 3 bugs make an infestation... I suppose when you tell someone you're going golfing, it just means you're going for a drive

It's the only kind of golfing I do!

I've always been one short of infested. Don't know how I feel about that lol.

 

[jmodge]

It's so insane. I can't believe people are asking as much as they are for them. I only got my wagon (Rebelle) for a good deal because it was going to the auction block and I offered a little over the trade in value. Even more unbelievable is what some beetles are selling for around here. I have seen a couple sell near the $3k range, with plenty of rust, dents, and no maintenance history.

That gives me hope for getting rid of my Jetta

 

[burpod]

finally did something i've wanted to do for a while... 205/65/16's (continental true contact eco plus) and put them on wifes golf... looks good. she's always complaining (mildly) about wanting an suv so i figure some bigger tires might help but 46.7mpg last tank. interesting to see how it runs with some bigger tires with bit of a rev drop

Diesel Fuel Hose 3mm (Return Line) - 1 Meter | eBay

LEADED UNLEADED AND DIESEL. ⚙Applications. Item Condition: New. Premium OEM Quality - Made in Italy.

www.ebay.com

This is what I bought. Not 100% sure it's viton, but it's diesel rated. I have multiple other engines with line on them so maybe I'll steal a piece. It's the wifes car so I wanted new stuff on it. Ideally she will eventually not have to worry about leaking fluids because I have almost replaced everything now at this point lol.

I really like this stuff for inter-injector return lines -grips like crazy:

I’m officially a Golfer

Congratulations! I've been looking for a wagon, but if a golf comes up for a good price, I'll get it.

As I understand it, between the two limit lines, and when running a stock tune, there is adjustment internally to hit what ever timing is requested. Go with some other tune, with a non-stock advance table/matrix and then those two limits are close to meaningless.

Douglas

The graph shows static aka mechanical timing regardless of tune - that's why it's labelled basic settings. Some claim setting it towards the upper limit helps winter starting, I call anywhere in the top half good.

regardless of tune, but depending on your fueling, what is best is going to be very different. i never run anything above the blue line, cold starts have not been a problem. there's a reason why different engines (different fueling) will show different graphs. for .260s 11mm i will set below the red

 

[jmodge]

Someone ran a video on static timing that I’ve followed that usually ends up slightly retarding basic timing . Aligning specified and actual in basic timing, they start good in cold weather

Is the front end being held up solely by that hydraulic jack? In which case...yikes!
There's no way I'd let anyone crawl under a car being held up by only a hydraulic seal.

Realize that the braking system in your car and every other light duty vehicle on the road is supported by the same hydraulic seal that your jack uses. The only difference is that there are a minimum of 4 of these seals in parallel (usually more) so there's an even higher probability of a failure than on a hydraulic jack which only has one .

 

[Nuje]

I'm guessing that most jack-related injuries are related to the car falling off the jack more than the jack failing, but that again - a jackstand is gonna reduce that risk greatly as well.
(as will a 10x10 or 6x6, of course)

I agree, Or using super worn jacks that slowly fall if you were to leave the car weight on it overnight. That's always been my test. Soon as it starts to fall a block or something becomes the failsafe so I'm not dead. I also will put a catch under the car as well if I know I will be shaking or moving things vigorously that could cause the jack to slip/fall.

Jackstands are generally safe as long as they are on cement. On dirt things get interesting, which is why I don't use them a ton unless I am doing a clutch or using as a floorjack failsafe. They just tend to be more unstable on the dirt.

I welded 12×12 steel plates to mine so the legs don't leave divots in my asphalt driveway. Now they are safe to use on dirt too.

Overnight? Mine is so bad I have to hurry to get the jackstands in. Lol

It has been so long since I put the timing belt on and got the garage cleaned up, I don't remember which timing belt kit I got. It was one of those that came with the hepu antifreeze, thermostat and everything else needed, I'm pretty sure it was continental, but I can't remember the name to remind myself if it was a $60,000 mile belt or what the replacement interval is

Wow, I knew we were dealing with inflation, but even still, a $60̷,0̷0̷0̷ belt seems a tad much.

Dictates software always adds a dollar sign if I say the word thousand. Of course it forgot the mile

No it did get the mile in there, I just thought it was funny.

Man, all this jackstand talk got me fired up- here’s a pic from today’s rear brake job
https://flic.kr/p/2qr79oH https://flic.kr/p/2qrbzUP Doubling up on y’all’s advice !
There’s even a floor jack under there!
Brake job went pretty good - I had to trim the calipers with a grinder to make room for spacer adapters that are to fit a stupid large bolt pattern.
🫤
It was an impulse buy and now I’m making do- live and learn.
I recently got a smart phone and watched my self control pack up and leave.
I gotta pump the brakes on this Jetta obsession see what I did there ?

 

[The Cream Dolphin]

Alright @Nuje ... I have tried and tried to find it but I am yet another victim of the troublesome search function. I tried site:tdiclub.com in my google search with what I thought would be the right buzz words in many combinations, and searched for a while, would you be able to point me towards your how to for coolant gauge long coding? I want to make mine accurate and recall seeing your post. TIA

The serp belt idler is going to get replaced too.

the little plastic guy seems to outlast the tensioner roller at least 2:1 which is funny because nobody seems to sell the tensioner pulley on its own

 

[[486]]

these engines really run much better when you don't run over-advanced... however, whether what you do in the graph here makes much of a difference depends on what is loaded in the ecu and your fueling hardware. too much advance leads to low end torque, most noticeably.

Hey, in your thread on tuning do you ever go into detail on injection timing?
I keep meaning to do a bunch of datalogging runs to figure out the most efficient timing through watching the IQ versus whatever steady state cruise speed I'm at, but it's one of them things that I'll never get around to


ETA: timing in the maps, not on the sprocket

i still haven't gotten around to writing up my thoughts/findings on timing.. want to one of these days.

you can use timing adaptation to more quickly test out certain areas (like cruising), however what timing works best will of course be tied to your boost/duration maps you have for those areas, which may or may not be "correct" (as in IQ numbers close to reality)

when i log/drive for efficiency testing i am watching all the relevant numbers - IQ/fuel-consumption+speed, boost EGT from gauge, IAT, spec/actual timing, coolant temp and then the conditions, focusing more on flat/no-wind areas but also other common situations like doing a low-grade incline @ some speed say 75mph. kinda drives one crazy lol.

 

[[486]]

I'm just looking at it as ideal timing being the most efficient conversion of fuel into movement, too advanced is causing cylinder pressure spikes, and too retarded is squirting the heat out the exhaust port (which can be handy for catalyst heating, or waking up a lazy turbine)

doesn't help that VW datalogging is at like 0.5hz

 

[oilhammer]

The ALH doesn't need anything "fast". It's sort of the engine management equivalent of the Apollo stuff. It gets the job done, with very little.

 

[[486]]

I got spoiled with datalogging in the kilohertz range and the graphing provided by that tunerstudio stuff when I did a megasquirt car a while back
that system is just downright magical when compared to beating my head against the wall with the bosch stuff.

you can see the little spikes in map from valve float, it's just amazing when compared to the garbage that scan tools give you

 

[oilhammer]

I would imagine that when the manufacturers (be it the engine and/or engine management) work through the initial design they use as much of the best tech available, and once the design phase is done, the OBD side of things only needs to do so much. But keep in mind, the EDC15 system, the first generation, came about in 1990. How fast were computers then, and who had access to what? There really wouldn't be any sense in making a system that had anything beyond that capability, and to even a "slow" computer the pistons moving up and down at redline are probably like watching water freeze. I'm actually somewhat suprised that the later EDC15 systems even bothered to employ a hot film MAF, as even that seems totally beyond necessary (and some of the newer VAG engines did away with them altogether).

I remember using scan tools that were pre-PC that were little more than a slow interpretation of blink codes put into text on an LCD screen. And when the PC stuff did first come about, we were using MS-DOS stuff through a serial data port just like a dot-matrix printer. It worked fine, because the cars just were not that sophisticated.

Now, these new UDS cars have on-the-fly calculations for the pulses of the timing chain and can display the "stretch" of the chain AND calculate both camshaft phasing (or in the case of the V engines, FOUR camshafts) individually along with the individual valve lift from the little solenoids on the heads above each valve. It really is mind boggling to think of how much stuff is going on in these newer engines. Really makes the VE TDI seem like a dinosaur. Which is exactly why I like them, and why they are so tough and durable.

 

[norbert77]

46 km since she backed out of the garage. Several times I've noticed at low throttle acceleration that it seems like I ease off the throttle and get back onto it, but if there's a dead spot for a couple seconds. How would I check to see if it's a throttle position sensor, or is there something I can run a log for? Seems to be a very low throttle


Also something is different, rolling in first gear if I floor it, it lays rubber, before it used to just briskly accelerate

 

[[486]]

Really makes the VE TDI seem like a dinosaur.

but their internal communication is at high speed just the same
the "smooth idle IQ adjustment" whatever that's active at low rpm shows that, adjusting the injected quantity cylinder by cylinder
vp44 dodges will even use this to do a 3cyl cold idle, snapping the control collar to defuel between cylinders
