You can also clarify the location of the fault. An effective diagnosis will reduced risk of costly and prolonged repairs. The codes received in MaxiEcu are described, so there is no need to have professional knowledge to interpret them. Before erasing, you can also save the faults in the diagnostic report in .pdf format, allowing you to keep full overview of the fault history.


This option in MaxiEcu allows you to view many parameters in real time. At the same time, you can observe all parameters, obtaining their detailed values. Without additional tools or a need to open the hood, you are able to work out the technical details of the vehicle and find any irregularities in the operation of the system. The obtained parameter values are presented in a clear and comprehensible way. The data can also be automatically saved to a report that you can read in a spreadsheet.


Graphs give us enable to make a visualisation of the working of many parameters. Graphical presentation of the value is especially beneficial if you want to verify signals changing at a high frequency. Analysis as a graph is also possible while driving the vehicle, so you have the opportunity to directly observe the operation of selected parameters. Graphs have also undoubted advantage, that thanks to them, checking the correct operation of the subassembly becomes simple and clear.


The basic and inseparable function during cars diagnostics. Thanks to which you can check whether a given component is working properly. The MaxiEcu software, using Tests, enables elements to be activated and checked – even if the controller doesn’t meet the conditions for the component to be switched on.
