• ECU covers removal
Tip : The screws that secure the covers will have thread locking compound applied from factory. This is
a high strength locking compound so make sure you use a screwdriver with a tip which fits the screw
head properly. We use a cordless drill-driver. The combination of quality screwdriver tips available and
being able to use an adjustable clutch makes this method far superior
.
• Conformal coating removal
Remove the coating from around the header on both top and bottom of ECU circuit board and around
SMD jumpers using solvent or contact cleaner (see later in document for jumper details).
