B&M 46059 COMMANDFLO, BLUE - Manual

We added a high flow exhaust that
increases airflow 5%. What pressure
should the system be set to?
F1 = 270 cc/min
F2 = 284 cc/min (270 + 5%)
P1 = 43 psi
P2 = 43 psi x
or
P2 = 48 psi
We recommend that you read
through the instructions completely
before beginning the installation, so
you can familiarize yourself with the
installation procedure and tools
required. Check the tool list at the
end of these instructions for the tools
required to install your B&M
CommandFlo Fuel Flow Modifier.
Installation of the CommandFlo Fuel
Flow Modifier can be accomplished
by anyone with minimum mechanical
experience. It is however, important
to closely follow the instructions.
When installing your CommandFlo
Fuel Flow Modifier there are several
other B&M products you may wish
to consider: B&M Fuel Pressure
Gauge Set: #46053 or #46054. In
order to take full advantage of the

©2000 by B&M Racing and Performance Products
The B&M CommandFlo Fuel Flow
Modifier has been designed to work
on all 1988 thru 2000 Honda Civics/
CRX's and 1990 thru 2000 Acura
Integras/NSX's, except those models
with TBI (Throttle Body Injection).
The B&M CommandFlo Fuel Flow
Modifier allows the user to accurately
adjust fuel flow (and hence fuel
pressure) in response to engine
modifications.
Most factory computers will
compensate for minor airflow
modifications (low restriction intake
and exhaust) at part throttle operations
but have no way to adjust at WOT
(Wide Open Throttle). The results are
a lean mixture right where you need
more fuel! One way to correct this is
to adjust fuel flow via fuel pressure.
Most people don't understand that by
increasing fuel pressure (on a fuel
injection system), fuel flow increases.
The formula for calculating flow
increase based on fuel pressure is:
F1 = Injector Flow (cc/min)
P1 = Current Fuel Pressure (psi)
F2 = New Injector Flow (cc/min)
P2 = New Fuel Pressure (psi)
P2 = P1 x
Example:
Fuel Flow Modifier, it is important to
know the exact fuel pressure of your
system. #46053 also includes adapt-
ers for various import and domestic
applications.
INTRODUCTION
The B&M CommandFlo Fuel Flow
Modifier can be installed in less
than an hour by carefully following
the instructions. Read all instruc-
tions first to familiarize your-
self with the parts and proce-
dures. This kit contains all parts
necessary to install the fuel flow
modifier on all Honda Civics/CRX's
and Acura Integras/NSX's.
DISASSEMBLY
We suggest the vehicle be allowed
to cool for an hour or two before
you begin since you will be work-
ing around the fuel system.
CAUTION: THE FUEL SYSTEM
CONTAINS FUEL UNDER HIGH
PRESSURE EVEN WHEN THE
ENGINE IS NOT RUNNING. BE-
FORE DISCONNECTING A FUEL
LINE, WRAP THE FITTING WITH
A R A G T O P R E V E N T F U E L
SPRAY.
