14.09.2005: Saab NG900 ECU Replacement

Home

ECU (engine control unit) replacement on a 1996 900 turbo. The original ECU is being replaced with an upgraded unit from Nordic.

Tools:

	14.09.2005 Glovebox Remove the glovebox -- six screws around the perimeter and one 10 mm bolt below by the door.		14.09.2005 Connector Pull the glovebox out, unplug the bulb connector.
	14.09.2005 Harness Before removing the ECU, disconnect the battery or pull the "Trionic" fuse (#28). Move the carpeting away. Unlock ECU harness by pulling the lever and unplug it. Undo a screw in the lower right corner. The ECU slides down.		14.09.2005 ECUs The new ECU plugs right in. After the installation, perform an adaptation run by doing a series of full throttle accelerations in high gear from 2000 to 4500 RPM. It helps if you can find a long road going uphill.
