1985.0 Porsche 944 - BOSCH Motronic Fuel Injection models ML1.1 & ML1.2 
1985.0 model year Porsche 944 all have EPROM sockets built in.  A performance chip (EPROM) just plugs in.  Also, if a DME was replaced on warranty by the factory in 1985 or after, they too will have EPROM sockets. 

Model years 1982 thru 1984 may need converting. There are two methods to do this.   Read this linked page...

Technical:   Early 944 DMEs Compatibility issues... Do not use Euro chips in US DMEs.  
Early 944 DMEs for use in the US/Canada/Japan are not compatible with Euro/ROW DMEs. The DME calibration for fuel is very different. 
Euro/Row DME chips and US DME chips are not interchangeable.
 
Technical:   Early 944 DMEs Compression Ratios  
Euro/ROW engines have a high Compression Ratio of 10.6:1 while US engines have a ratio of 9.5:1

PowerPROM - "Race-Chip„ PowerPROM - "Lambda-Chip„

PowerPROM Versions - a brief description of the different PowerPROM available.

"Race Chip" - Performance chip for the 944 with or without an O2 sensor. The O2 sensor is not needed.
                           Best for all around performance.

"Lambda Chip" - Performance chip for the 944 that requires a functioning O2 sensor.  US DMEs only....

The Lambda Sensor, also known as an Oxygen or O2 sensor, are different names for the same thing. 

The Early 944 US version use a Catalytic Converter and lambda-sensor (oxygen sensor) and .   The ROW version does not.

1985.0 - Early 1985 Porsche 944 or Early 944.

1985.5 - Late 1985 Porsche 944 or Late 944.

Mid year 1985, there were design changes and the fuel injections model was changed.
