as we all expected....here is the guy's reply:

"Yes we do have programming for the 96 993, but it does require a special encryptionboard to enable use of a reprogrammable eprom in the ECU which the cost is not cheap. 1996 993 is the only year which requires this, we can reprogram 1995, 1997-1998 without this speical encryption board as they changed the ECU in these years. Cost you would be looking at around $1600 due to the high cost of the encryptionboard."

However $1600 doesnt sound so bad. I wish it was $1600USD

any opinions?

Methinks I'll be leaving mine alone.

and by leaving yours alone........your car will start.

A random question: did *every* '96 993 come with a non-flashable ECU? The reason I ask is because my car is one of the last '96 993's built -- in the final weeks of that year's production. Is there any chance that my car has a '97 ECU installed? (Not likely, but worth a shot.)

Me too....too many potential hassles for me in Cali with this cat **** they call gas..ethanol diluted crap.

I've seen a few cars titled as a '96, but with the '97 (.376) ECU.

Its worth a look,...

NP993

Steve, I'm assuming that .376 is the last three of the part number for the ECU?

My car was built in June '96, the last month of production for the 96 models,* so maybe just maybe I'll get lucky.

*June being the last production month is Jeff Smith data, so it's his fault if I'm wrong :lol:

EDIT: Never mind, yes, you were talking about a part number. The search button is my friend!

Okay, well, it looks like the Porsche gods decided to not do me this very special favor. The silver sticker carries a part number of 993.618.602.00, and while it appears that the other part number -- the one that ends in .008 or .376 -- is rubbed off, from this previous thread, it seems certain that I have a '96 ECU. Bummer.

I guess it wont hurt to check mine too.....how do u check it? where is it located, and do I have to remove anything?

Steve Weiner-Rennsport Systems

The Porsche part number means nothing in this context: only the Bosch numbers tell you what it is. It looks like this: 0.261.204.xxx and those last three numbers are the key ones.

If its .008, thats a '96 twin-chip ECU.

If its .376, thats a '97 single-chip ECU.

If its .649, thats a '98 single-chip ECU.

When the numbers have been rubbed away, the only sure way to tell is to remove the ECU, open the cover and look at the circuit board.

Keeping the dream alive! Thanks Steve. :lol:

I'll go check again.

Keep us posted, Noah. I have a pool going.

Steve are these HP numbers correct 22hp with this mod.

WHAT WOULD A USED 98 ecu BE WORTH.

Also what about a group buy could he lowe the price.
