The BMW e36 Link is a direct plug in replacement of the factory BMW ecu. The factory ECU case is used to cover the Link board. A small modification to the case is needed to allow for a vacuum line to connect to the internal Link ecu features an on-board 4.0 MAP sensor.
With the Link BMW e36 OBDI M50/S50 plug in standalone engine management "chip tunes" are a thing of the past. This engine management system allows for tremendous flexibility and can handle any custom engine set up from NA to turbo / supercharged combinations this plug in unit is up to the task.
The BMW e36 Link works excellent with E30 swaps where an M50/S50 wiring harness is used. The package will also work with other standard (M52 / S52) and custom displacement engines as long as the M50 / S50 harness is used and the car is converted to OBD1 configuration.
This ECU will also work with manual transmission M50 vanos E34 5 series BMWs
