1 Mounting and Sensor 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. 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.
Make sure the mounting location does not impair visibility or
interfere with driving.
1.1.1 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.
1.2 Fuel Pressure Sensor
•The fuel pressure sensor can be mounted onto any 1/8 27 NPT port.
•Before disconnecting any fuel line connections make sure to
depressurize the fuel system.
•Check for fuel leaks and address them accordingly before
driving the vehicle!

2 Wiring
2.1 Main Gauge Wiring
1. Connect the RED wire to a switched 12V source. A switched 12V source
comes ON as soon as the ignition on the car is keyed on. Make sure the
connection is fused with a minimum fuse size of 2A.
Circuits that share power with the vehicle’s stereo, ignition
system, ECU or fuel pump should not be used.
2. Connect the main BLACK wire to a ground source. Note that there is an
additional black wire coming out of the 3 pin connector, this is not the
main gauge ground and will be covered later in the Fuel Pressure sensor
wiring. Avoid noisy ground sources, such as grounds used for the radio
and or ignition.
3. Connect the WHITE wire to a headlight power wire (a wire that supplies
current when the headlights are on). 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.
2.2 Fuel Pressure Sensor Wiring
1. Route the pressure sensor cable to the gauge and connect it to the 3
pin connector.
2. Coming out of the female three pin connector from the gauge you
will find a black wire with a stripped end. Connect this black wire to
the same ground source as the gauge.
3. Connect the other end of the pressure sensor cable to the fuel
pressure transducer.

3 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.
3.1 Installing software
1. Double click on the Logworks 3 installer previously downloaded.
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 the MTX-A manual can then be located by navigating
through Start->Programs->LogWorks3.
3.2 LM Programmer Software
LM Programmer is used to configure the pressure alarm and upgrade the
firmware
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.
Avoid connecting or disconnecting any of the ports labeled
IN or OUT while the unit is powered ON.

3.2.1 Pressure Tab
The pressure alarm setting can be configured in the Pressure tab in LM
Programmer. When the pressure 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
3.2.2 Updating the Firmware
The LM Programmer Info tab reports the firmware version currently installed
on your unit. 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 unit.
Firmware for the MTX-A Fuel Pressure gauge has the extension dld. New
firmware releases are available for download on the Innovate Motorsports’
web site (www.tuneyourengine.com) under ‘Support.’
1. Power OFF the MTX-A gauge
2. Connect the supplied serial cable to the port labeled OUT.
3. There should be nothing connected to the port labeled IN.
4. Power ON the MTX-A gauge.
5. Connect the serial cable to your computer. If you are using a serial to
USB adapter, connect the serial cable to the adapter then connect
the adapter to the computer.
6. Launch LM Programmer. The LM Programmer application can be
launched from Start->Programs->LogWorks3->LM Programmer from
the Windows task bar.
7. Once connected the 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.
8. On the very first tab of LM Programmer you will see a button labeled
“Update Firmware,” click this button.
9. Select the firmware file with the dld extension.

10. Do not disconnect the unit 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.
If your computer crashes during a firmware upgrade, the MTX-A gauge has a
recovery mechanism where it will be able to retry the download again and
not be disabled by half loaded firmware. Switch the MTX-A gauge off and on
again and then reload LM Programmer. The recovery mechanism is
designed to be able to recover 99.9% of the time. While we don’t anticipate
this occurring, it is possible that the MTX will not recover correctly and may
need to be serviced at our factory. If you suspect this is the case, contact
Innovate support.
3.3 LogWorks Software
The MTX-A gauge can be connected to the LogWorks software to record and
analyze the fuel pressure readings. The gauge can also be connected to
other Innovate Motorsports products to create a log chain with additional
gauges and sensors.
3.3.1 MTS Serial Communication
The MTX-A gauge has a port labeled IN and a port labeled OUT. These
connections allow multiple MTS (Modular Tuning System) devices to be
connected together in order to form a single log chain.
There are two types of cables used to interface the MTX-A gauge. The 3812
cable is a 4 pin micro fit to 2.5mm male stereo plug used. The 3846 cable is
a 4pin Micro fit to 4pin Micro fit. These cables are sold separately, make
sure to select the correct cables to interface the product you own.
1. Power OFF all your MTS devices.
2. Start with the first product in the serial chain. Using the appropriate
mating cable, connect the OUT port from the first device and feed it
into the IN port of the second device. (Note: If you have an LC-1,
there must be a terminator plug in the serial IN if it is the first device
in the serial chain.)
3. Continue connecting the OUT port of each device into the IN until
all your devices are connected together.
4. If a recording device is not connected to the serial chain, e.g. DL-
32, LM-2, the OUT port of the last device can be connected directly
to a computer to log with the LogWorks software

5. Once all the connections of the ports labeled IN and OUT are made
the MTS devices can be powered ON.
3.3.2 Logging data
1. Power OFF the MTX-A gauge
2. Connect the supplied serial cable to the port labeled OUT.
3. Power ON the MTX-A gauge.
4. Connect the serial cable to your computer. If you are using a serial to
USB adapter, connect the serial cable to the adapter then connect
the adapter to the computer.
5. Launch LogWorks. The LogWorks application can be launched from
Start->Programs->LogWorks3->Logworks3 from the Windows task
bar.
6. Once LogWorks launches go to File->Connect. You will be prompted
to connect to serial COM port. Click Connect.
