How to Remove the V6 ECU

Tool required: 7 mm socket, long 10 mm socket.

The V6 ECU is located under the hood on the back of the intake manifold, next to the throttle body. I have highlighted it in red (Pic 1). Before removing the ECU, disconnect the positive battery cable and remove the plastic engine cover.

(Pic 2) Begin by removing the two large wire connectors from the ECU. Depress the plastic tab and pull back on the metal lever. A flat screw driver may be needed to help depress the tab. Do not use too much force, wiggling the lever as you pull it helps.

(Pic 3) With both connectors removed, unscrew the grounding wire for each connector. Each one is attached to the ECU with a 7mm screw. Their location is indicated buy the red arrows and the socket is on the left one.

(Pic 4) With the connectors and grounds completely disconnected, now remove the ECU with its backing plate. It is held in place by three 10 mm bolts. The top two are simple to remove. The third is hidden below, centered at the bottom of the ECU bracket. Picture 4 shows the socket on the bottom bolt. The good news is that the bottom bolt does not need to be removed, only loosened. Back out the bottom bolt until you can pivot and slide out the ECU.

(Pic 5) The ECU is removed, two 10 mm and two 7 mm bolts have been removed. The third 10 mm bolt is still in the intake manifold.

Now put the ECU in the mail for a good tune.
