Product description of the DM Pro power module
The newest arrival from DM Meccanica is the DM Pro programmable power module.
Using the supplied cable harness the DM Pro is installed downstream from the stock power module and before the throttle body.
In this way the data which is sent from the stock power module can be modified according to necessary requirements.
The DM Pro can in fact change the carburetion relationship independently
to the one which has been set by the motorcycle manufacturer by
changing the time interval in which the injectors remain open during the
intake stroke.
Very often on all factory motorcycles there are limits and standards which are necessary to
guarantee the compliance with emission regulations and to adjust the engine to perform well under any condition.
For this reason the performance can be improved in relation to the
pressure and temperature of your actual location whether for example you
are out on a trip down by the sea or on a ride through
the mountains. An add-in such as the DM Pro is also essential should you
decide to add to your motorcycle an after sales exhaust system and a
race air filter as both require an optimum carburetion to achieve the
best possible performance.
The power module is easily programmed via the USB connection on a PC
Computer with a simple and intuitive method: instead of using the
classic table of numerical values which can be found in all commercially
available programmable power modules, the DM Pro is programmed by
simply creating a 2D carburetion chart.
Featuring a Plug and Play system, the DM Pro is connected to the
injectors, the IAT sensor and to the 12v ignition power (this is to
avoid a powerless motorcycle absorption effect).
The choice
of using the IAT sensor is strategic and is necessary to change the
anticipation values without giving you the doubt that it will cause
damage to the engine should the settings be either incorrect or too
high.
Once you have synchronized a reading of the engine's RPM with the
supplied software, you will then be able to create your own personal
carburetion mapping by using the arrow cursors on your computer's
keyboard.
The program screen is very simple and intuitive showing the relationship
between the engine speed (from 0 to 12,000 rpm for the DM Pro 2 and
from 0 to 17,000 rpm for the DM Pro 4) and the carburetion scale which
by it's reference axis can be increased to a maximum of +30 or reduced
to a minimum of -10.
Initial setup
1. Connect the DM Pro to the USB port of your computer (it is advised to use the same USB port each time you connect the DM Pro)
2. Begin a search for the COM port by clicking on the button “Search for DM Pro”
3. The software should automatically detect the COM port to which the DM
Pro is connected to your computer and this will be shown in section
marked “Virtual Comm”.
4. Once you have received the confirmation of a connection between the software and the
power module, it is now possible to work with the injection curve.
Creation of the Injection Curve
1. Before creating an injection curve, it is recommended to carry
out an initial bench test to analyse the stoichiometric value to be
corrected.
2. Begin the connection between the DM Pro and the power module of the motorcycle by
pressing the button “RPM Monitor”
3. Check the dial and modify the multiplier of the engine rpm using the
value control “RPM Divider” Confirm the changes by clicking on the
button “Update
Profile on DM Pro”
4. Create a flat profile by either increasing or decreasing the initial
carburetion using the button “Flat Profile Value”. Confirm the
generation of profile by clicking on the button “Generate Flat Profile”.
5. Once you have analysed the stoichiometric value, you can change the
injection curve using the arrow cursor keys of your computer’s keyboard.
You will need to click on a point of the Injection plot using your
mouse and you can use either your mouse or the arrow keys to make any
necessary changes.
6. Load the injection curve onto the ROM of the power module using the button “Update
Profile on DM Pro”.
7. Once all of the tests have been carried out, save the corrected injection curve onto your
computer using the button “Save Profile”.
NOTE: All
of the changes made using the software will be carried out ONLY AFTER
the update of the Rom has been made by clicking on the button “Update
Profile on DM Pro”
5). Note A: If you are using the software fully maximised and depending
on size of your computer screen, the arrow keys on your keyboard may not
allow you to change the points of the injection plot. If you find this
problem, we suggest that you minimise the software window to a smaller
size or only use your mouse to make any changes.
To connect the DM Pro to your motorcycle, you will need to locate both
the injectors and the air temperature sensor. Once you have found the
injectors and the air temperature sensor, disconnect each of the plug
connectors already on the bike and connect the relevant plug connectors
of the DM Pro to your bike and to the connectors you have just unplugged
by creating a bridge connection. Finally you will need to connect the
black wire to the Earth of your bike’s battery and the red wire to a 12v
source on your bike (e.g. headlight, petrol pump). If you are unsure
about the installation, we highly recommend that you speak with a
mechanic for assistance.
