The ISSPRO R4130 Turbo Temp Monitor helps eliminate early turbocharger failure in
diesel applications. When engine ignition is turned off, the
R4130 idles until a safe exhaust temperature is reached, then
automatically shuts down the engine. By shutting down in a cool
condition, deposits are reduced and turbo life is increased.
Standard shutdown temperature is 300° F. Operating voltage is 12 VDC. For installation, the existing
pyrometer system can be used or order complete kit below. The
TTM is Field adjustable: the temperature set point can be
adjusted by removing the cover and rotating the trimmer.

1: Ignition Switch: Keeps
engine running. (16AWG wire recommended)
2: Batt+: 12VDC A switch can be inserted in this lead to
defeat the TTM.
3: Lamp: an optional indicator lamp can be used to display
temperatures above the safe limit when the ignition switch is
4: GND: Ground
5: T/C-: The thermocouple (-) lead. Usually red lead wire.
6: T/C+: The thermocouple (+) lead. Usually yellow lead
location is post turbo (exhaust down-pipe). If your
existing pyrometer thermocouple is pre turbo (exhaust
manifold or up-pipe) we recommend that you purchase one
of the kits (R4130-AT or R4130-CT). If you already have
a Pyrometer, we recommend that you give us a call to
verify that it will be suitable for use with the TTM.
If your down pipe already has a 1/8"NPT threaded bushing
installed you can use the R4130-AT kit and change the thread
size on the thermocouple by purchasing an adapter fitting, part
R4130-AT Kit comes with the ISSPRO R4130 TTM,
10' Hi-temp Lead Wire, R658 adjustable Thermocouple, 1/4"NPT, and R680 Weld Bushing, 1/4"NPT.
This kit is recommended
for Dodge Cummins applications. You will drill and tap the exhaust elbow 1/4"NPT.
The kit's included weld
bushing will not need to be used.
comes with the ISSPRO R4130 TTM,
10' Hi-temp Lead Wire, R650A-HT Inconel tip adjustable
Thermocouple, Band Clamp style. This Kit is recommended
for Ford Powerstroke and GM Duramax applications You
will drill a 1/4" hole in the downpipe and insert the
thermocouple there secured with the included band clamp.
The ISSPRO TTM will not work with the BD XMonitor.
ISSPRO TTM vs. Turbo Timers -
The ISSPRO Turbo Temp Monitor is not a turbo timer.
When activated, turbo timers will keep an engine running at a
predetermined rate of time, usually an incorrect amount of time.
Most Turbo Timers allow for the user to adjust the amount of
time that they run, but most drivers don't know how long that
time should be even if there is a Pyrometer gauge in the truck.
Usually turbo timers allow for shut down times in 1 minute
increments. This means 0, 1, 2, 3 minutes and so on.
This does not allow for the flexibility required for most
shutdown situations (less than 1 minute). Example 1:
By the time you pull into a parking lot at the local grocery
store, the temperature at the turbocharger may be as low as
325°F. When the ignition is shut off, the ISSPRO TTM will
keep the engine running the correct amount of time before
shutting down. In this case it's merely seconds.
Sometimes the turbo may be cool enough that the TTM will not
even activate at all. With a turbo timer, more than likely the
engine will be kept running too long, wasting fuel. Even
with turbo timers that allow for finite (second) adjustments,
how is the driver to know what's the correct amount of time?
Example 2: Lets say the ambient temperature is 90°
outside. You're towing a heavy trailer up a moderate grade
on the highway for a duration of a few minutes. At the top
of the hill you decide you need to pull into a rest area.
How long should you set a turbo timer to run for? Good
question. The time could be up to several minutes.
With the ISSPRO TTM you don't need to worry. It will shut
the engine down at the right temperature every time.
The ISSPRO TTM does not operate like a self-powered thermocouple
gauge. The TTM has its own separate power source.
Self powered pyrometer gauges make their energy when the
thermocouple heats up. Examples are: Banks, Westach,
Western Diesel, and old series DiPricol pyrometers. These
gauges can sometimes be inaccurate, as under hood temperatures
can effect the reading at the gauge. The ISSPRO TTM
operates just like the ISSPRO Enhanced Visibility series of
gauges. They are accurate and under hood temperatures are
not a concern.
