The Dynojet CMD Marine (Combustion Management Device Marine) is
an easy-to-install fuel controller gives the end user full control of the fuel curve
in an easy to adjust format for the ultimate in air/fuel ratio tuning.
Pop the hatch to install the CMD Marine units, and within a few minutes you’ll have
the power to control your engines fuel curve at the tips of your fingers. Our testing
has shown impressive gains in fuel economy on all stock engines, while being flexible
to support future modifications. Want to install those new headers or camshaft,
the CMD Marine gives you the ability to tune the engine for a proper fuel delivery
curve without the downtime of shipping your ECU off for recalibration. On a stock
502/500HP, we achieved a 28% increase in fuel economy in the midrange RPM’s with
no other changes!
Changes are made to the engines’ fuel curve via the CMD Marine’s onboard microprocessor.
Using this technology, we are able to offer a large area of adjustment without making
any permanent changes to the ECU (electronic control unit). Removing the CMD Marine
modules returns the engine to its previous stock condition.
The unit comes complete with software and USB cable link that allows you to change
between different maps or make adjustments to a map file. The USB port provides
an instant, no-hassle way to connect the CMD Marine unit to today’s’ computers.
For the ultimate in fuel tuning, you can combine the CMD Marine unit with one of
our wideband oxygen sensor monitor devices for real-time air/fuel ratio display.
This will show you precisely what air/fuel ratio your engine is running at, giving
you the vital information as to what changes are necessary. The CMD Marine also
has a feature called AutoTune, which gives you the ability to set a target air/fuel
table within the software, and have the CMD Marine automatically tune while you
drive. You simply set the software to the air/fuel ratio you desire, and it will
create trims on the fly! You will then have the ability to implement these trims
to the base fuel table.
The WideBand 2 unit gives you one channel of oxygen sensor input. The AT-300 unit
offers dual oxygen sensor input, allowing owners to tune each bank of the engine
individually, for extremely fine control of air/fuel ratio. If you would like to
be able to monitor these readings, as well as other information from the CMD Marine
units, our LCD-200 display gives that to you in the palm of your hand. This touch
screen display device also gives you the ability to log all channels to an internal,
user supplied SD card. With the maximum 1gb SD card installed, the LCD-200 can log
up to 186 hours of data!
The Dynojet CMDM will be available directly from Dynojet Research, Inc. You may also be able to purchase
this device from an authorized reseller that has met our qualifications.
