Hi, a friend is working on a 944 and has come across a part located under the steering column and appears to be directly linked to the ECU. If anyone know what this part is and what function it performs I would be very grateful.

Many thanks

Neil

I tried to follow the mystery relay link but it wouldn't work. I found the following as one of the posts under that heading (before I saw that it was added here)... It is about third page in ...

RENNLIST TEXT follows

Lilja.. based on some reading I've done, that was an 'experimental' relay (basically a "flasher blocking relay") Porsche put into some 84-85 models which altered the air-fuel ratio going into the computer (pin#13 I think) for the first ~2min~40seconds or so. The same way a flasher relay intermittently blocks the power to a turn signal light (making it flash) the relay would interrupt power to a function in the DME that would alter the air-fuel ratio. (Possibly by interrupting fuel injection cycles) This function was later provided within an updated DME relay, which is why it is not there in later cars. Some more research indicated it is indeed part number 944.615.915.01. There is one for sale on eBay.co.uk for ~40usd.

END TEXT

Best to search up the rennlist forum entry .... following the post above there is another post that refers to a Porsche bulletin regarding fuel injectors... the fact that your car runs with it and barely runs without it suggests this may be related.
