Calterm Cummins software is a tool that allows access to the internal calibrations of engine computers for the Cummins manufacturer. By downloading these files, modifications can be made to certain internal calibrations.
This software is very useful when specific tests are required on a machine.
The importance of knowing how to use this software lies in the ability to make modifications to the operating parameters of the ECM (Engine Control Module) or engine control computer.
It is important to clarify that if you make permanent modifications to an ECM, it may affect the machine’s emissions system, which in some markets is subject to verification by government entities.
What parameters can be modified using Calterm Software for the Cummins manufacturer?
The latest generation Cummins engines come with many new features, designed to increase their power, performance and regulations.
Some of these systems that are installed in this type of engines are:
EGR: Exhaust Gas Recirculation or Exhaust Gas Recirculation.
The EGR valve is installed for the purpose of recirculating many of the gases that come out of the exhaust, and directing them back to the intake system.
Which means that these gases or fumes are taken back to the combustion chamber inside the engine cylinder.
In this way, a reduction of NOx or Nitrogen Oxides is achieved.
VGT: Variable Geometry Turbine or Variable Geometry Turbo.
The variable geometry turbo system is a novelty compared to traditional turbo chargers.
This system has an actuator that allows the position of the turbo flaps to be modified, achieving efficiency and higher speeds.
An inconvenience that occurs when the EGR parameter is modified in a Cummins ECM is that the exhaust gas temperature is no longer regulated.
The new VGT systems are not designed to withstand these types of temperatures when there is no control by the EGR.
Therefore, special programming procedures must be executed to avoid affecting the VGT system.
FAULT CODES: Permanent Fault Codes
It happens when parameters within the ECM are modified and components are permanently disconnected.
It is necessary to modify the ECM programming tables to permanently erase active Fault Codes, which in most cases “slow down” the machine.
Calterm Cummins Metafiles
A concept that you must master to start with Calterm Cummins Software are the famous Metafiles.
Calterm Cummins Metafile Files
These Metafile files are data structures that are used to be installed within the memory of an ECM and contain data maps with certain engine performance modifications.
The most common file types are: E2M, EFCG and BIN.
For this reason, it is essential that you master the use of the INCAL Cummins library, which you must install with great caution.
Setup to Work with Calterm Software in a professional manner.
Because the use of this software requires a lot of concentration, we recommend having a Diesel programming laboratory, in which you will have a basic setup.
ECM module to modify EGR VGT using cummins calterm.
- Use of exclusive Laptop for Calterm Software and others. It is not advisable to use the same computer for other purposes.
- Use of Interfaces with communication protocols accepted by the ECM. This interface can be Cummins Inline, however, other interfaces are also accepted.
- Always try to use reliable and original diagnostic tools, otherwise you risk permanently damaging an ECM.
- Harness to connect the Cummins ECM.
- Regulated voltage source, to supply power to the ECM during the diagnostic and programming phase
Cummins calterm 4.7 installation instructions
1.Install LCT1.12.0.17.exe under the LCT folder
2.Install java.exe
3.Install Calterm4v4.7.1.007.exe
4.Run HWID6.exe and click copy to Clipoard to get the machine code
5.Open KMforKM.exe in the registration machine and paste the machine code in the box under HWID, a random name in the box 1 or abc will be okay and click make key
6.Open the km.lic file in the generated lics folder and copy it to the KM folder,keep them both in same folder,so that you can open the registration machine KM.exe
7.Click HWID6.exe again and click copy to Clipoard to get the machine code, paste it in the HWID box of KM.exe,write any name you want then click make key
8.Open the newly generated lics folder and find this cc.sn file, copy and paste it in installation directory of calterm.
9.Copy Calterm_ start.exe and fnp_ _ld.dII, paste them into the installation directory of calterm.
Then send a shortcut of calterm_start.exe to the desktop. Click the shortcut of calterm_start.exe every time you use it.
CALTERM The program for the diagnosis of Cummins engines. Calterm 4.7.1 is an engineering development tool used to monitor Electronic Control Modules for Cummins engine systems and to alter the calibration data contained therein. Calterm is designed to modify fueling calibration parameters and feature settings in an engineering development and test environment.
