from against the firewall. Pull the ECU out of the
firewall toward the front of the vehicle. It may be
necessary to remove the rearmost bolts attaching
the flexible inner fenderwell to the body to provide
clearance to remove the ECU.
Note the code printed on the plastic cap on
the back of the ECU. This code should compare
to the code printed on the Banks OttoMind™ box
label. Pry the plastic cap from the rear of the ECU
using a small screwdriver, exposing the printed
circuit board edge connector inside. Retain the
plastic cap. The connector will be coated with
grease and a clear silicone type coating which
must be completely removed before installing the
Banks OttoMind engine calibration module.
Clean BOTH sides of the connector. First,
clean the white grease off with a tissue.
Next, scrape the clear silicone type coating
from the connector fingers with the abrasive
square provided. It is very important to clean
both sides of the board in order to have a good
connection between the ECU and the Banks
OttoMind module. It is only necessary to clean the
connector fingers. Be careful not to damage any
circuit traces on the board further inside the ECU.
Orient the module so that its edges line
up with the edges of the ECU. If the edges
do not line up, or it looks as if the ECU will not
fit back into the hole in the firewall, the module
is rotated 180 degrees off. Place the OttoMind
module over the connector, and press firmly to
seat the connection. DO NOT FORCE the OttoMind
onto the connector, as damage may result to
either the ECU or the module. If the module
does not install with firm pressure, check the
orientation and try again. Place a piece of duct
tape over the module, fastening it firmly to the
ECU. See Figure 17 .
Before returning the ECU to the recess in
the firewall, it is a good idea to reconnect
the wire harness and the batteries and start the
vehicle. The vehicle may not start if the coating on
the ECU connector is not completely removed or if
there is a mismatch of codes. A quick indication of
module connections that are not cleaned properly
is that the “Wait to start” indicator will fail to light
and the “Check engine” warning indicator will
stay lit after the key is switched on. If the engine
fails to start, re-clean the ECU connector, reinstall
the module and try again. After the engine has
started, shut it off, disconnect the batteries
and the ECU wire harness, and complete the
installation.
Reinstall the ECU in the firewall. Reinstall
the retaining plate against the firewall.
Reattach the wire harness to the ECU. Reinstall
the inner wheel well bolts, if removed. Reconnect
the batteries.
