YOU CAN remap 96 ECU (extra 22HP)

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?

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.)

Its worth a look,...

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.

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.

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.

I'll go check again.
