Be certain battery ground cables

have been disconnected. locate

the engine control unit (eCu) in a

recess in the firewall on the engine

side, between the steering column

and the left front fender. all that will

be visible is an elongated electrical

connector and wire loom, surrounded

by a retainer plate attached with two

nuts. see Figure 16.

remove the bolt attaching the

electrical connector to the EcU,

unplug the connector, and swing it

out of the way.

remove the two nuts and

retaining plate 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.

start the engine and allow it

to warm up. Drive the vehicle,

listening for any exhaust leaks or

rattles. adjust and tighten clamps

or reposition the piping if required.

when positioning of piping is

finalized, it is a good practice to

place tack welds at any slip joints

in the exhaust system to prevent

slippage. NOTE: The exhaust may

smoke slightly after initial startup.

This is normal and will go away

shortly as the grease used in the

bending process burns off the inside

of the piping.
