OBD1 to OBD2 convertor

[Mr.FixitNorm]

Hi All,

Found this whilst trawling ebay today, just wondered if this would work with an `88 S' ???

http://www.ebay.co.uk/itm/Porsche-19-pin-OBD1-OBD2-connector-Adapter-OBD-Cable-968-993-944-964-and-928-/220992269925?pt=UK_Diagnostic_Tools_Equipment&hash=item33742a6e65

Seems to good to be true if it does - really cheap, has anyone tried one. I have a mate with a OBD2 diagnostic reader, if this would work with my car it would be good

I don't think so.

The dme will output data if enabled, but only as a serial stream.

Also, As far as I am aware, we don't have any 19 pin socket for the eBay cable to plug into.

Regards

Graham

Hi Graham,

Just checked my porsche 944S pdf manual and realised the diagnostic plug on the DME ( 1988 on ) is a odd ball 12 pin , so obviously no good - damn!

Only works with the special Porsche diagnostic tool[8|]

I thought the diagnostic tool was actually just a LED?? You can actually make one for a few quids worth of parts from RS or maplin. The information it will give you is actually quite limited though. Just a blink code that will tell you if you have a problem with a specific area. It's not like the OBD2 reader I have for my other cars that I can monitor on the lappy and give you live data. It's just not that sophisticated.

944 S & S2 models have connector next to glove box (LHD vechiles).

That cable is a cheap copy of Durametric software/cable. It uses old Durametric 3.6 software (illegal copied version). If you try to use newer Durametric it locks the software and cable. New Durametric software can identify if cable is a clone or a real thing. I have tried this cable with old Durametric, but it didn't work neither S2 or 968. When you used just OBD II cable without that old style Porsche plug, it worked with Boxster. These cable are advertised usually as "Porsche Piwis Cable"

Here's couple of pictures of my cable

Rob, the `diagnostic' tool shown in my `Porsche Shop Manual' is a 9268

It has a multifunction LED and a 4 digit display

Olli - are you saying with the lead I found on ebay and the `old' Durametric 3.6 software it is possible to get diagnostic info on a laptop or not?

Yes, if you have a 944 S or S2. 16V models have a diagnostic plug. You still must have a so called Porsche Piwis cable to go with it (see my pictures). In my case chinese clone cable/plug & pirate version of Duramteric 3.6 didn't work. I tested it with S2 & 968.
Just in pure OBD use (without oldstyle Porsche plug adapter) it worked with Boxster. If you want a properly working version, get a real Durametric.

Hi, your picture above shows the round connector to fit the porsche, however my S2 still has the rectangular 12 pin connector. Has anyone ever seen a convertor that takes the 12 pin rectangular to a standard OBD connector?

Cheers

That's odd. i have a 1989 S2 cab in my yard and it has this 19 pin connector under dash next to glove box.

I wasn't aware of any such plug on my S2 at all. I didn't know it was sophisticated enough to store fault codes for later reading. (I'd have thought the engine is so simple such a thing is neither built-in nor necessary.)

Blink codes are a fun game to play; I built a blink-reading LED for an old Mk3 Golf I once owned, and actually getting meaningful information out of it was nigh-on impossible!

My 1990 car has a round pin plug by the glovebox as well - doesn't work with the after market chips though. Not checked the cab though
