missing a sapphire blue in there...call me next time!

We're a bit of a commute from Texas. But let me know if you ever roll through town.

Another day of cars and coding. It's been almost exactly a year since I started this thread! 24k miles added to the odometer since then and haven't looked back.

Has anybody used PIWIS 3 to code the EPS? That's the version I used today and it seems to be quite different from what the videos show on PIWIS 2. We could not find a way into Engineering Mode following the video PIWIS 2 screen shots and instructions. I think we were stuck in Diagnostic Mode, which allowed going into EPS, but only to check its status. I think being stuck in DiagnostIc Mode would not allow me to select Coding, but every time I backed out of it I could not find Engineering Mode. It is likely that I missed something. Does PIWIS 3 require different steps to get into Engineering Mode?

Bumping this question. I got access to the above version of the Launch X431 and wonder if/how I can use it to set it. I have seen one comment that said they were able to use a Launch X431, but they unfortunately did not provide more details (e.g., which exact model and how they got access to the programming mode). Thanks for any help in advance.

I read in 718 section that someone used Launch X431 Pro to code as long as it has bi-directional capability.
Still hoping that we can have a tuning party in Pacific Northwest US-Canada this summer using PIWIS 2.

Let me see if I can get the version I have to work (it has bi-directional capability). If so, I am happy to offer help if time and location works out.

Yes it works with piwis 3.
Diagnostic mode is correct, but you have to have and be in the german mode/version it's 39.XXXX, for me it's under the regular diagnostic mode you selected. I forgot the exact numbers. Everything will be in german that's how you know your in the programming mode, I believe at best in the normal/english version you can only do coding which is not capable of EPS programming.

also, fwiw I had the Servotronic/Porsche Power Steering Assist on for 3 months and it was horrible exiting parking. Definitely do not enable it.

I did mine using PIWIS 3.
It could be possible that the PIWIS 3 setup you are using doesn't have engineering mode enabled. Most of the versions floating around online do, but if you used an official version at a dealer, for example, it's probably not.

To switch modes (if enabled properly):

• Go “System” from the main screen.
• Select “Diagnostics configuration for 991, 981, 918, 970, Cayenne from MY11, Macan”.
• Select “Mode”.
• In the “Operating mode” dropdown, select “E”.
• Choose “Save” at the bottom of the screen, and then exit that screen with the “X” at the top, and confirm.

To code the EPS:

• Go back to the main screen and select “Diagnostics” to get started.
• Once you are connected to the car, select the “EPS” module and then “Coding programming” in the top bar.
• Choose “Manual coding without coding rules (development)”, then “Next”.
• Select the “Kodierwert: Codierung Fahrzeugklassen” option, then “Next”.
• Change the “Value” to “GT3”, and then select “Write” at the bottom to save.
• Then you can exit out of diagnostics, and you're done!

Edit: Took me so long to compose my post, I didn't realize the question had already been answered! Hopefully the detail is helpful.

I made a video on how to enable it in piwis 3 for you:

Here's a video the enable the PTV torque vectoring in piwis 3:

Your instructions are perfect. I made a video with them.

Thank you so much @pedal bliss and @01010011 for providing what should (hopefully) enable even me to code the EPS in my Spyder. I had to put the car away late yesterday because of the weather today. If the weather looks better this afternoon I will make another attempt, courtesy of you guys!

If we are asking and receiving the step by step wishlist (thank you for the great work on the steering) can someone provide the step by step for programming steel brakes to PCCB (to avoid ice mode) and to turn off monitoring of the driver's thorax airbag (for aftermarket seats)

Mods - maybe we make a sticky or a list of how to program functions

Thank you!

Here is the setting you're referring to. I'm not sure that ice mode was still an issue for 981/991 cars though. At any rate I'm not able or willing to test this out on public roads haha.

Sorry about having to keep coming back to this thread, but I am still having a problem with coding for the EPS (Electric Power Steering), so here are my questions:

1. Has anyone actually been able to change the EPS coding for a 981 Boxster Spyder, from 981 Spyder to GT3 RS?

2. I first tried to follow the instructions on the post by @01010011. I was able to get into Engineering mode on our PIWIS 3 clone, then followed his instructions by changing the “Value” to “GT3RS” (note: I also tried to do all of this by selecting “GT3” instead of “GT3RS,” also without success).

3. After I changed the “Value” as indicated in (#2 above), I selected “Write” at the bottom of the screen. Upon doing this there was an “error” message at the top left of the screen (“10010 Error occurred while writing”). At the same time, under the topic of “Value,” the selection went back to “981 Spyder.”

4. I was not able to get beyond this “error” message. I noticed in the video by @pedal bliss, at about 3:42 he has this same problem when he attempted to change his “Value” to “918.” At the top left of his screen there is the same “error” message, and instead of the “Value” being changed to “918” it went back to “GT3.” I do not know what conclusion to draw from his inability to go from “GT3” to “918.” This is exactly the problem I am having when trying to change the “Value” from “981 Spyder” to either “GT3RS” or “GT3.” Both of these EPS values are showing on the drop-down menu for me, but I am not able to successfully change the EPS to either of those (because I get the error message and the value goes back to “981 Spyder.

5. I think what all of the above means is that, at least so far, I am not permitted by PIWIS 3 to change the coding value of the EPS.

Some further inputs shown on the @pedal bliss video that perhaps I do not understand are:

6. It appears that when @pedal bliss opens PIWIS 3 in his video he had previously changed his EPS code"Value" from the original “981 S, Cayman” “Value” to “GT3.”

7. He was able to change his EPS coding values from “GT3” to “981 S, Cayman” successfully (see top left of his screen: “coding has been written successfully.”) He was also able to change back again to the “GT3” “Value” as well. You can see this between 3:40-4:14.

8. Between 4:40-4:56 he selects “Entwicklung: Codierungen Fahrphy…” in addition to “Codierung Fahrzeugklassen.” What is the purpose of selecting the both of above?

9. At 4:56 he has attempted to change the EPS “Value” from “981 S, Cayman” back to “GT3” but this time it fails- he gets the same “error” message. He then goes back one screen and selects “GT3” from the drop-down menu, then selects “write” at the bottom of the screen, and this time “GT3” is coded successfully. Why does it work this time?

10. @pedal bliss does some additional coding, I think about “power steering plus” though I’m not certain.



I certainly hope @pedal bliss does not think I am criticizing him in any way. I am just trying to get this damn Porsche coding to work on my car.
