Hi.
I want to read out my 93c86 chip of my BoxsterS 986 facelift instrument cluster.

I have TL866A programmer.

Can sombody tell me if it is possible to read and write the chip with this programmer?

I've changed my instrument cluster to a version with the better graphic dot matrix display but want to correct the mileage.

Is it right the mileage is stored in lines 300&310 and 500&510 in a 2kb dump file?

My thougt is to copy these lines to the new cluster.

Any recommendation to use the programmer?
I found a pdf instruction. The author recommend to short the crystal on the PCB.

Am I right I dont need any power supply to the PCB? It is enough to connect the 93c86 with an IC clamp?
Thanks

I have only used PST2 or PIWIS1 for coding cruise control on a 986.  I recall that early software versions of PIWIS2 caused problems coding cruise, so perhaps the feature was removed.  The option doesn't appear in simulation mode either, so I suspect that might be the case.  Do you know anyone with a PST2, PIWIS1, or Durametric Pro who could try?

Richard do you have a wiring diagram for cruise control for a 2003 Facelift BoxsterS?

I want to double check it.

Thanks 

Installing cruise control and OBC stalks to my 2003 BosxterS Tiptronic with segment cluster.

The OBC works great but with cruise control I have some questions.

In PIWIS I only find a "Tempostat" entry in DME coding section.

In the instrument cluster coding section I only find the OBC entry but no Tempostat entry.

In DME I have changed to cruise control.

When I switched on the ignition and push the cruise control button on the stalk nothing happens.

Must the engine run and must the car driving to set cruise control?

I can see the LED on the PCB of the instrument cluster.

If it is possible to change the 7 segment to dot matrix with soldering skills?

With which ordering options Porsche installed the dot matrix?

Only if you ordered OBC and/or PCM2?

Why the 7 segment also is prepared for OBC? Was this option also awailable or never used?

Therefore only for us enthusiast? 😜

When I enable the OBC I also want to enable cruise control. My instrument cluster doesn't have the Tempostat LED in the speedometer gauge.

Is cruise contol possible without the LED?

Yes, your current instrument cluster will give you OBC if re-coded.  You will still have the 7-segment OBC display, not the "dot matrix" display of models with factory OBC, but you will get the OBC functions.  They will appear below the existing two lines.

7-segment:

 

Dot Matrix 31.72 kB · 0 downloads
 

I have successfully coded my Instrument cluster to OBC.

I also have the 7 segment version.

After coding I can't see any changes Do I need the stalk?

I thougt the outside temperature is shown after coding.

I also have coded PCM2/CDR23 to enable because my car has CDR23 with Bose from factory installed.

Does the entry has any impact?

From the Overview screen, press F7 for Additional Menu.  At that point you will be asked if you want to create a VAL.  Choose 'No at this point.

On the Additional Menu screen, choose Vehicle Analysis Log (VAL.  There you can select OBD VAL or Service VAL.  Choose one, press F8, and follow the on-screen prompts.  At the end (after confirming the VIN), you get the choice to select a log type - Choose Miscellaneous.  Then press F12 to go to Report Management.  Select the log, and press F10 for Print.   Print it out to PDF or a connected printer.

Thank You very much.

However, this is not a backup of my devices or is it possible to play this setup back into the ECUs later in case coding failed.

Do you have a screenshoh where I can make a VAL?

 

If it is Piwis 2 or 3, just run a VAL.  An OBD VAL will give you coding of DME and Tiptronic.  A Service VAL will give coding of all control modules.

Noob question of Piwis.

How can I save my coding of the ECUs?

I was in DME unit and want to save the coding. The system confirmed thats it is saved.

But where I can find the file?

Is it possible to export this file? 

Hi.

Searching for the "order code" of a 2003 Boxster S Tiptronic LHD RoW (German Version).

Is it also 986320?

Is there a overview or list of all order codes?
