1. Installation
1.1 Gauge Mounting
The MTX-A gauge fits in any standard 2 1/16” (52mm) gauge pod.
Mounting of the gauge should be done in such a manner that the cables are
not being forcefully pulled and strained from the gauge itself. Route the
sensor cable avoiding contact with sharp and hot sources that could damage
the cable. Also avoid routing the cables near ignition components or other
sources of RF (radio frequency) and EMI (Electromagnetic interference)
noise.
The MTX-A gauge is splash resistant (not water proof) and can be
mounted so that it is exposed to the outdoor elements. The MTX-A should
not be submerged and special consideration should be taken to protect the
gauge from direct water spray (water coming from a pressurized source.)
When replacing the bezel and/or gauge face verify that the o-ring is properly
seated. When replacing the bezel and/or gauge face verify that the o-ring is
properly seated.
1.2 Temperature Sensor Mounting
The water temp sensor provided in the kit has 1/8 PT external
threads.
Mount the sensor using Teflon tape over the threads to avoid fluid
leaks.
Be sure the sensor wire is not twisted. Having the wire twisted will
damage the sensor.
Avoid bending the sensor wire near the sensor body.
1.2.1 Changing the MTX-A’s Gauge Bezel
1. Lay the MTX-A face down and remove the three #2 phillips screws
from the outside rim of the back plate.
2. Carefully lift out the bezel from the gauge cup.
3. Configure the gauge as desired making sure not to disturb the
needle.
4. Make sure every piece is positioned correctly using the locating tab
and reassemble the gauge.
5. Reinstall the 3 #2 phillips screws.

1.3 Main Gauge Wiring
1 Connect the RED wire to an isolated switched 12V source in your
vehicle. A switched 12V source goes ON as soon as “key on” power is
active. The circuit to which you will pull power from should be able to
support a 2 amp draw. Make sure this connection is protected with a 5A
fuse.
Circuits that share power with the vehicle’s stereo, ignition system,
ECU, lighting, or fuel pump should not be used. When in doubt, create an
additional circuit using an automotive relay available at any automotive parts
supplier. See the next section for a relay installation diagram.
2 The BLACK wire should be grounded to a solid ground source. The
best possible ground source would be the battery ground (-) post.
If other Innovate Motorsports devices are going to be daisy-chained
along with the MTX-A, it is recommended that all devices be connected to a
single ground point, ideally the battery ground (-) post.
3 Connect the WHITE wire to a headlight power wire (a wire that supplies
current to the headlights). This enables the display to dim for better
nighttime viewing. DO NOT CONNECT THIS WIRE TO THE
HEADLIGHT DIMMING WIRE. Connection to this rheostat type of
switch will cause the gauge to malfunction. If you chose not to utilize the
dimming feature, connect the WHITE wire to ground.

1.3.1 Single Innovate Device Relay Wiring Instructions
1.4 Temperature Sensor Wiring
1 Fish the Water temp sensor’s two pin connector through the firewall and
to the MTX Water Temp/ Volt Gauge.
2 Connect the sensor’s male two pin connector to the female two pin
connector on the gauge.
3 Coming out of the female two pin connector of the gauge you will find a
black wire with a stripped end. Connect this black wire to the same
ground source as the gauge.
2 Download the Logworks 3 software package
1. Open your web browser and go to:
http://www.innovatemotorsports.com/support.php
2. The LogWorks 3 software download will be the very first thing on the
page, click the link to download the software.
2.1 Installing software
1. Double click on the Logworks 3 installer previously downloaded.

5
2. The installer will start, follow the prompts to install the software.
3. Once the software has been installed the LogWorks software, LM
Programmer and MTX-A manual can then be located by navigating
through Start->Programs->LogWorks3.
2.2 Connecting to LM Programmer
LM Programmer is used to update firmware, change fuel types, and program
the two analog outputs.
1. Connect the OUT port of the MTX-A to the provided serial
programming cable. Connect the other end of the serial
programming cable to your computer. If your computer does not
have a serial port, you can purchase a USB to Serial adapter from
Innovate Motorsports (P/N 3733) or use any USB to serial adaptor
that includes drivers. Make sure that nothing is connected to the IN
port of the MTX-A
2. Power up the MTX-A.
3. Launch LM Programmer. The LM Programmer application can be
launched from Start->Programs->LogWorks3->LM Programmer from
the Windows task bar.

6
2.3 Temperature Alarm
The temperature alarm setting can be configured in the Temp tab in LM
Programmer. When the water temperature threshold has been exceeded the
entire gauge’s backlight will flash. To enable this feature, the “Enabled”
option must be checked.
Whenever a change is made to the programming of the gauge click the
Program button for the change to take effect. Once the gauge has been
programmed the Program button will grey out.
To set the gauge back to the factory settings click the Set to Defaults button
and then click the Program button
2.3.1 Updating the Firmware
Do not update the firmware if the versions are the same. A
firmware update should only be necessary if there has been a new
release that specifically fixes a problem that you are experiencing with
the controller.
1. Connect the MTX-A to the computer and launch LM Programmer.
2. Once connected, LM Programmer will display the current version of
the firmware that is installed in the MTX-A. Do not update the
firmware if the versions are the same. A firmware update should
only be necessary if there has been a new release.

7
3. On the very first tab of LM Programmer you will see a button labeled
“Update Firmware,” click this button.
4. Select the firmware file with the dld extension. If there have been
revisions to the firmware, you will find them available for download
from the Support section of the Innovate Motorsports web site.
5. The software will now prompt you to confirm that you wish to
overwrite the firmware currently on your MTX-A.
6. Click OK, DO NOT power off or disconnect the MTX-A from the
computer until the firmware progress screen completely disappears.
Once finished, you may disconnect the unit from the computer and
exit out of the software.
2.4 Logging data from your MTX-A with LogWorks
1. Connect the OUT port of the MTX-A to the provided serial
programming cable. Connect the other end of the serial
programming cable to your computer. If your computer does not
have a serial port, you can purchase a USB to Serial adapter from
Innovate Motorsports (P/N 3733) or use any USB to serial adaptor
that includes drivers. Make sure that nothing is connected to the IN
port of the MTX-A. Power up the MTX-A
2. Launch LogWorks. The LogWorks application can be launched from
Start->Programs->LogWorks3->Logworks3 from the Windows task
bar.
3. Once LogWorks launches go to File->Connect. You will be prompted
to connect to the serial COM port. Select the COM port the device is
connected to and then click Connect.
4. To start recording go to File->New Realtime Log or, in the Toolbar,
click on the Tool.
2.4.1 Adding and Logging MTS channels
The Innovate Motorsports’ MTS (Modular Tuning System) allows you to
daisy chain multiple devices together via the serial IN and OUT connectors to
form one single synchronous log. MTS log chains can consist of a single unit
connected directly to a laptop (connect your MTX-A directly to a computer,)
two units, or multiple devices connected together, up to 32 channels
Innovate Motorsports’ MTS devices have two types of serial interface
connectors, the legacy 2.5mm stereo and the 4 pin Molex. The following
patch cables are available to interface your devices together:
4 Pin Molex to 4 Pin Molex - 4ft p/n 3846
2.5mm to 2.5mm Stereo - 4ft p/n 3760
2.5mm to 2.5mm Stereo - 6in p/n 3789
4 Pin Molex to 2.5mm Stereo - 4ft p/n 3812
