Dynojet Announces New Product: CMD Marine
North Las Vegas, NV, March 1, 2011 - Dynojet Research, Inc is proud to release the first
applications of the CMD Marine (Combustion Management Device) for retail sale. This easy-toinstall 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.
The first units available are:
• CMDM-5010 for Mercury Marine 496Mag / 496HO engines
• CMDM-5011 for Mercury Marine GM based spread port big block with EV1 injectors
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!

Future offerings under the CMD Marine lineup are to include a Whipple supercharger application,
small block applications, Ford engine applications and many more.
The features of the CMD Marine include:
 Small footprint for easy mounting (for V-8 applications, 2 modules at 5/8” x 3-3/8” x 25/16”) edit as necessary
 USB powered from computer (can be programmed off-vehicle)
 2 position map switching function built in (map switch not included)
 3 optional analog inputs allows user to tap or add any 0-5v sensor and build an
adjustment table based on its input such as temperature, throttle position, etc)
 Individual control per engine bank (left and right)
 Unit has a -100%/+250% fuel change range.
 High resolution MAP sensor based fuel table for precise fuel changes
 Automatic map retrieval upon connection
 Onboard notes storage
 Quick connect CAN accessory communication ports for LCD and AutoTune accessories
AutoTune for CMD Marine:
 AutoTune kit is available as a single channel wideband O2 sensor or dual channel
wideband O2 sensors
 Plugs directly into the CMD Marine using the CAN accessory ports
 Single channel wideband feedback will adjust the entire fuel curve for both banks. Dual
channel wideband feedback will adjust the fuel curve for each bank of cylinder
independently.
 Each map cell is individually adjustable so you can specify an exact air/fuel ratio value
desired for each area if needed.
