We have different ways to test the MDEC ECU when we have to repair it, simulating all the sensors as RPM, temperature, pressure, digital channels and signals or injection.
You can see one photo with the box where we can control the external temperature as you can have in an engine room during operation. We simulate the conditions to make the ECU running as in the engine, activating the injection and modifying speed or other values, this belongs to our main simulator where we do a lot of test. The unit is installed in our complete BlueLine simulator to make the unit running, but during 2025 we have been developing a simulator to work in our repair engineers bench to simulate all conditions and take internal measurements with multimeter, oscilloscope, changing values and looking for fails or following different internal signals.
As this unit became obsolete, in 2024 we noticed an increase of repairs on these MDEC units, so we decided to improve our possibilities to repair them, going deeper in the simulation. We designed and developed this prototype to be able to connect on the ECU, not only on this model, it will be available for other models of MTU ECU´s. We are on last stage to finish it, now working on the software side. Each board connected on motherboard would be prepared to simulate different channels, sensors or conditions. The idea is that each of our engineers will have this unit on the bench to work on ECU repairs.
In 2.025, we continue repairing a lot of these ECU´s for different companies or end users worldwide, with one year warranty, as you can see, with very specialized tools developed by our own company to make the repairs as much professional as we can. I will share more details when the unit is fully ready, I hope you like what we can offer you, also sharing these type of internal technical information.
