I had some time to play a bit more today. First off, I pulled the SD card and put it in the computer (via microSD to card adapter, and then into the laptop card slot). The drive shows up normally, and you can navigate as expected.

I then tried using FoxAssist to see what it does with the data. FoxAssist sees the drive/card directly in the "Data Manager" section. However, it doesn't seem to do anything with it. You can run the "report" but that just plays back the data about once a second in the table. So stupid. I will stick to processing the data myself into an Excel.

I ran a 10-second capture to see how much data shows up. Unfortunately, it seems to show 13 data points. Sure, I may have been off by a second or so, but certainly not 3 seconds... so the data rate is unknown or variable. Again, so stupid that they don't put in time stamps.

I also tried to see if I could capture two different "pages" of data... ie the "Engine Speed" from one page and the temperatures from another. Apparently, this doesn't work either... you only get to save data from that one page. Maybe there's a way to create a custom list in there, so you can save what YOU want, but I haven't dived that deep.

I did two other drives, on cold days, to see how the warmup looks. First drive was 41 minutes long... the first half is at city speeds, the rest is highway. The car was fully warmed before the highway. This drive was run at 20F outside (1/4/22 in my area of CT). The 41 minutes took 3577 datapoints. Calculated out, this averages to about 1.45 datapoints per second. Engine temp leveled off at ~84C (183F) and then 323 datapoints later the oil temp leveled off at ~84C as well. 323 datapoints / 1.45 points per second = 222 seconds = 3.7 minutes.

Second run was today. This drive was much slower (slower than city because it was crazy icy in the morning, even though it was warmer). Air temp was around 32F.and I only recorded for 26 minutes... all was slower. Unfortunately, this captured 1750 datapoints, which comes to an average of 1.12 points per second. Again, so stupid that there is no timestamp. Anyway, going deeper says that this trip took 6 minutes to warm the oil to 84 (after the engine temp read 84).

Anyway, bottom line, if you want to collect data, we need to find a way to get timestamps. Beyond that, between 3-6 minutes after the engine is warmed up (7 minutes per my previous analysis) the oil temp reaches the stable point.

Let's look at it another way. If you look at the oil viscosity vs temp you can see graphs like the one shown here: https://www.kewengineering.co.uk/Auto_oils/oil_viscosity_explained.htm

The last graph (Graph 4 at the bottom) is most useful here. In there, you can see the oil reaches proper viscosity well before hitting 70-75C. That being said, I'd theorize that the engine is sufficiently warmed up when the coolant temp hits stability... because even with the oil at 70C, it's pretty close to what you want for viscosity at "normal" temp of 84C. Bottom line, I feel fine saying my car is "warmed up" when the engine is up to temp. Heck, I might even say it's warmed up well before that...

Sorry for the rant... just exploring the data (I'm a data ***** as you can tell) and making judgements based on what I see. I'm no engine or oil expert, but I think my conclusions are reasonable?


In other news... anything anyone else might be interested in having me dive into? :)

I don't know for sure. I see "TPM" in the list, and you can also see the module in the "gateway"... but from some quick searching I have not seen people have success by removing the module and eliminating the warning light (I assume that's what you're looking to do). However, the user there did email Foxwell and ask them to fix this... so maybe it works now, I don't know.

Mine is working, so I don't think I want to delete it to find out. Besides which, since it's working I don't think deleting it will help me see if the warning goes away anyway?

My friend emailed Foxwell asking if his Mercedes convertible top can be tested, and they did tell him this does work... so you may try contacting them to see what kind of answer they can provide? Lastly, you can buy on Amazon and try it out... if it doesn't work, you can return it?

Whatever path you choose, it would be great if you can report back. I see that disabling the TPMS is something a lot of people seem to want to do!
 
I just got my 530 yesterday. my car is a 2008 987.1 non-PDK.
I have changed my steering wheel from the awful triangle with tiptronic switches, to a paddle wheel from a 2012 987R. I had to replace the EU module just to get the horn to operate. The airbag light was on but the 530 cleared this easily.

The paddles do not operate, PSM light is on.

How do I use the 530 to code the new EU in the steering?

I'm not sure how this is done, and you may be better off posting your own thread instead of posting within mine (though, I agree, it might be nice to have a single thread with these questions and answers for the NT530).

I don't recall if you were the same user who has posted this matter on another thread, but I recall someone saying that you may not be able to do this "natively" unless you have a PDK, as the paddles are designed for that?

The other user mentioned that they figured it should work the same, since it's just switches, but when dealing with a CANbus setup, they are not "just switches" and may issue different command structures to accomplish the task. Honestly, I'm not sure how the Tip or PDK operate, so I am just guessing.

That being said, if you wanted to swap to paddles, and you just want them to behave like "switches" then you may be able to rewire the paddles to emulate the "awful triangle" switches you describe (I don't even know what this is - that's how little I know about the Tiptronic)... but, again, that's not a programming thing but a wiring task. I'm happy to help but, again, this might be better suited to its own thread.
 
I would have to agree on the issue with the paddles vs tiptronic rockers - it should be in it's own thread.

And this thread probably should move over to the diagnostics forum, where we are going to try to gather all info on various diagnostic tools and their use with different Porsche models all in once place.

I'm fine with having it moved - didn't even know there was a diag subforum... now I do.

Granted, my OP wasn't really a guide, but I think it might be valuable anyway? I would suggest leaving a link-back to this forum, since that's what I tested on and where others might look for it (for now at least?) But I'll leave the decision up to you!
 
Yes I do have another thread but little help and before I got the Foxwell 530.

So now if I rewire the switch paddles to act like Tiptronics and put the old EU back in, then my horn won't work, because that's wired differently. Yikes. Looks like I need a wiring diagram for both systems. 30 years of working on and teaching 747 avionics, and a 'simple' gear shift has stumped me. So if it's a can bus it would be a word lets say 32 bits (This is just theory), then in that word two bits would represent up shift and down shift. A momentary ground on one wire to the EU for up and one for down. The EU then sends the word out, i.e. xxxxx00xxxx no shift xxxxx01xxxx up shift xxxxx10xxxx down.

Yes, true, it should just be a word (or whatever) but my guess is that the data may be in different locations. Ie, your example of xxxx00xxxx being the location might be for the PDK... it may be at 00xxxxxxxx for the Tiptronic. Alternatively, it could be command structures that tell the module what to do (eg "TP01" means shift up on a Tip... while "PD01" might be for PDK). Again these are just guessed examples.

In other words, I really don't expect the Tip and the PDK to have the same modules on the bus (assuming it's CANbus at all)... so they may have completely different data structures as well as different addresses. That's what I figure is really going on... but I could be wrong. Like you said, it would take a deeper dive to figure out... but it might just be easier to do the electrical wiring to the module, instead of breaking down the command words/structures/addresses.
 
Anyway, the reason I care about this is because everyone says to wait until the car is warmed up before getting on it... but no one can tell you how to know if you're warmed up or not! I hope
Hi Schwinn,

One way I found out about the car being warmed up is to do an oil level check. If it isn't warmed up, it will say "Engine Not Warmed Up" on the MFD.

This is for a 987.2 not sure about other models I'm afraid.

Cheers!

Great info, thanks. I took that and ran with it a bit further. At least on my car, today, I watched the oil temp as I drove (via the Foxwell) and kept asking for the oil level measurement. Thankfully, since I have a manual, it would take the reading if I was rolling as long as the engine was at idle (ie, clutched in)... so I could repeat the message as I drove (city speeds). I ended up getting to my destination and the coolant temp was at 175 on the dash for maybe a minute or so before it would allow me to take a reading. The Foxwell said this was about 73C (= 163F) for oil temperature.

Elsewhere, I had read that the ECU considers the engine "warmed up" to do an oil measurement at 155F (=68C)...

I posted more detail on the other thread where we were talking about engine warmup and such... it's in the 981 section, but I think that discussion is still somewhat relevant: car warmup
 
Most welcome Schwinn. 😊

I didn't know there was such a thing until I wanted to check the oil level one day while driving my kid to school.
I sorta know now the rough distance (on school days about a mile and a half and 8 minutes no thanks to crappy traffic) that I have to travel before the engine gets nice and warm in our very hot (typically 86-90°F) and humid (80+%) climate.
I'm the kinda guy the enjoys reading the car manual over and over trying to see if I can dig up something new each time that I might have missed before.

Cheers!

@schwinn Can you tell if the Foxwell NT530 will re-calibrate a PDK? Their list of capabilities shows that it can reset the learned adaptations, but I have been unable to determine if it can complete the calibration sequence. FWIW, I asked this of Foxwell and received no response. Just looking for more intel. :)
Thanks,
George
Today I tried to recalibrate the PDK of my 981 PDK with the NT 530. I cleared all errors in all controllers before. Then clicked through, started engine, parking brake was enabled, foot brake also. But all I got was "Not support this function.". Did this several times w or w/o foot brake, door opened etc. To no avail.
Is there anyone who could manage to get this procedure running with the 530? I'm quite annoyed this function is listed even in the support area of foxwell (Function List_Foxwell) but simply doesn't work.

Sorry, I don't have a PDK nor a 981, so I can't help you directly... I believe others have done this, but I'm not seeing a post with details of the process right now...

One more little piece of info I learned... the manual actually tells you what "warmed up" is on the engine oil. Here's p157 of my 2010 manual:

Apparently, Porsche believes 140F is warmed up for oil. Since I've seen the "not warmed up" message even when the dash shows 175F on the coolant, I have to assume this means it's watching the oil temp. I hope to check this with the Foxwell just to see if that confirms it... but the manual reference is good to know! :)
 
Well, I got my PIWIS and managed to get the car out of Transport Mode.
I then went in to play with fire and burnt myself big time.
Now, my PDK and Gateway modules are unprogrammed. 😂
Will update when I get an external power supply going for the car so that I can program it.

Oh my! :whistle:

Does the PIWIS have a function to record all the current settings before messing about with a module?

Oh, sorry, just realised we're in the 987 forum. :rolleyes:
That's not an issue. I'm considering moving this thread over to the Diagnostics forum.. since the NT530 isn't just for 987's.

Decided to move this thread over to the diagnostics forum, since we can use more input on NT530 experiences from owners of models besides the 987...

Hang on.. I'll leave a permanent redirect..
