That's a bummer. You can find convincing ... alternatives to the piwis at various friendly Asian retailers.

I have no experience with those, but a durametric will not be able to program the cd changer on a 996. I think auto logic is the only scan tool (besides those running the Porsche software one way or another) that can code the pcm MOST Devices.

Thanks, from what I've read the durametric pro might be able to. Hopefully someone with one a durametric could confirm.

I know it's been so painful just for one setting! I'll have to ask around only problem is that most good/recommended indys aren't that close to me. I'd prefer to buy the durametric as it's something that will come in handy anyway - if it can do it that is!

Doesn't show much coding on the 996 unfortunately.

Okay so no good news to report, Durametric support got back to me and neither the Durametric Pro or the Durametric enthusiast version can enable the CDC.

I was able to get a list of mechanics that have an active autologic Porsche subscription (all of 2 in Melbourne!).

The first I called on the other side of town wants $125 to enable my CDC

I'm considering building my own PST2 clone but its highly unlikely that i'm going to be successful seeming the hardware and software are proving exceptionally difficult to find - which I expected

Anyone want to loan me a PST2?? Pleasssssse?

So I wish I had found this document before I went:

Page 127 talks about enabling components

Anyone have a PIWIS II I can use? The dealership wont let me use theirs...

dan_189

FYI, confusingly its not under coding or programming...

Porschetech3

It looks a lot more confusing than it really is, A lot of the confusion is just with the verbiage or translation. Just doing it will become more intuitive if you have the goal in mind. The PIWIS tester will not damage or do anything that cannot be undone, just REMEMBER or RECORD what you do !! lol

I did have one instance where the PIWIS tester did nearly cause me to have to replace a DME in a new 997.2 with PDK. The first PDK that came into our dealership off the truck . It came off the truck and the PDK would lurch, the rev would flash up between shifts and jerk, shifted like **** and had numerous codes. After clearing the codes and doing a trans adaption and engine adaption I decided to reprogram the DME and PDK ( they must be programmed together). I recorded the software numbers and reprogrammed, the software that was in the PIWIS latest release was a lesser version than the car that just came off the truck !! Porsche told me that I would need to replace the DME to get the latest software( that came in the car) because it was not yet available to the shop/aftersales !! So Porsche ordered me a new DME straight off the assembly line, BUT the lastest update for the PIWIS came in first, so I was able to reprogram it back to the latest version instead ....

Anyway just remember to put all MOST components in order and do not have any extra's or missing components in the MOST list. When your done you will think about how easy it was.

Thanks Porschetech3, I have a few questions us recording the same as creating a VAL - vehicle activity log? Or by recording do you mean writing/screenshotting everything?

Also my required components vs actual components will differ as I don't have a cd changer I just need the car to expect one (so I can use the Dension) .

The screenshot above is me just using the simulation mode until my PIWIS II arrives.

Thanks!

Porschetech3

Creating a VAL is a good thing, it will have all your "before" codeing on it .and also screenshotting everything you change will make changing anything back to original configuration much quicker.

Since the PIWIS tester has no provision to include the Demison in the MOST loop, you will enter CD Changer in the position for the Demison, The Gateway will recognize it as a "possible" CD Changer. But it will communicate with it.

dan_189

Thanks Porschetech3, so ill enable the CDC with the Dension connected in the MOST loop?

So just to confirm:

1. Plug in Dension - ensure radio is working with Dension unit connected
2. Plug in PIWIS II
3. Create VAL + screenshot as I go
4. Select "CDR-23" or "Gateway"? from Overview and select -> maintenance repairs -> Expected MOST -> CD changer - Enabled - Write changes

From my research simulation mode uses options/values from a car that was previously plugged in?

In the simulation mode that I have (where I got the screenshot above) for 996 it's got "PCM2 MMI" but my car has a CDR-23 with an amplifier so would the setting still be under PCM2 MMI or CDR-23? I tried to look at the 986 but it too had PCM2 as an option without CDR-23. I also tried 997 in simulation mode but the MOST settings were under "gateway".

Going by memory from what I saw when we plugged it in at the dealership there was CDR-23 but we didnt click on the Maintenance/repairs tab!

Porschetech3

PCM2 is the "big screen" optional radio, yours will show up as CDR-23

Do a complete system scan , with everything plugged up, the PIWIS should recognize the CDR-23 and may have a # symbol indicating a fault code. Enter into the CDR-23/ maintenance repair menu, don't be afraid to look around at the lists, only one list will show you the positions 1-5 and have provisions for you to change /add/remove components or positions, the other is for showing the actual list as discovered by the CDR-23, or the required list . These lists cannot be changed, and are for information only.

Changing the MOST components position or adding/removing components is the only operation you can perform in this section of the tester, so don't be afraid. The other things you can do is to test MOST function, test speakers, test tone, test volume, test antenna signal, test radio display ect. None of this can do any harm.

dan_189

Thanks for that, thought mine would be under the CDR-23 option much appreciated!

I just got a little confused as the "actual/expected MOST" option was under "PCM2 MMI" and there was also another option called "PCM2" but the MOST settings wern't under that.

I though there might be a "CDR-23 MMI" option and as I don't actually have the PIWIS yet just trying to gather all the info I can

Porschetech3

MMI stands for Man Machine Interface, GW stands for Gateway, just some terminology used with PCM2.

I think you have just the right amount of knowledge to perform this without a problem, just don't get too caught up in the details and keep the main goal in mind, (to add a component to the MOST loop) Explore the lists of information and get a little familiar with what your looking at , then do the addition of the CD Changer (Demison) and go back and look at the lists again.

I would give you step by step instructions, but I don't have them memorized, they can change with version to version of the software. I've been retired for 3 years after having open heart surgery so it's been a while since I have performed one of these operations. Although it has never really been necessary to memorize the steps or I would have had them memorized, also the steps can change as the software is updated !! lol And the functions can change as the software changes, I have seen many functions added with software version Xyz but other functions that were previously there had not been carried over !! I think you got the steps close enough, you will figure out the rest as you go, you have a good grasp of what to do.

Just hook every thing up as it's supposed to be so that it can be recognized, then go in and add the CD Changer in the position in the loop, then check the actual list to see that it's indeed in the loop and in correct position and being recognized, then clear all faults.

Note that the "enthusiast" version of Durametric has almost no "activation" functionality. Durametric enabled the OBC setting in both versions, but (I believe) the Pro version is required to enable any other equipment.

dan_189

Thanks Porschetech3, thats whats been getting me is that between my research of PST2, then PIWIS I and then PIWIS II the way to activate the CD changer has...changed haha! Then again its in a different menu for the 996 and 997 in PIWIS II. Anyway i'm fascinated by the PIWIS and the software so when it arrives ill do a write up with some notes so that dealerships won't tell 996 owners "it can't be done".

I'll keep everyone posted

Thanks 5CHN3LL, I contacted Durametric as i've been looking for an excuse to purchase one but they advised neither the Enthusiast or the Pro version can perform MOST functions (like enable the CDC) which is a shame because I would have bought one if it did.
