Ready to install my new Tip ECU (GIAC Race version)
Start by moving the passenger seat all the way back
Closeup of where bottom screw is for taking kick panel off (2 screws total)
Closeup of bottom screw cover removed
Closeup of upper screw on kick panel
Kick Panel Removed (simply lift up from bottom of panel, then pull out and down to remove)
Plastic carpet trim piece removed (use a quick short pull straight up at the 3 locations. You can only see 2 locations in this picture. 3rd one is closer to the seat)
Lift up carpet (it's pretty stiff) and insert a short piece of 2x4 (that way you have 2 hands free to pull out the ECU box)
Lift front of ECU slightly and then slide forward about 1" or so, as there are 2 locating pins front and back that hold the ECU box from moving around under the carpet. You can then slide it out from underneath the carpet.
Open up the ECU's protective box
Install new ECU
Make sure you install ECU's protective box back into holder. Took me 40
minutes to install while taking pictures. No harder to install than Engine ECU.
