Need standard Chip for a 993
 

Can any one help, I am looking at purchasing a 1994, 993 coupe, that has a non standard RS ECU up grade and I would like to get a standard chip for the ECU.

Does any one know where you can purchase a standard chip without purchasing a new complete ECU?
or as a second option a good second hand standard Porsche ECU?

I imagine there are people that would be interested in swapping chips or DME's with you if your have an RS DME. Do you have the p/n on the unit?

Where are you located? With a 94 993 I suspect you are not in the US.
