The software solution published on Kyotechs' official website addresses engine ECU, excavator controller and monitor software issues as one system. It covers complete replacement of ECU and monitor units, remote-control refits of ECU and monitor programs, and program upgrades that reuse the customer's existing units — the route that avoids buying hardware for a software problem. Programs are customised to the machine model, and the published service scope includes modification of EFI engine DPF, DOC, EGR and SCR system programs and resolution of GPS lock problems.
What the Service Covers
- Complete replacement units — ECU and monitor supplied ready to install where the original unit is dead or missing.
- Remote program refits — ECU and monitor program upgrades handled remotely, without sending units back for testing.
- Reuse of existing units — program upgrades on the customer's own ECU and monitor, avoiding unnecessary hardware cost.
- Model-specific programs — software tailored to the machine model, with compatibility and performance as the stated goals.
- Emissions-system program work — DPF, DOC, EGR and SCR program modification, with the necessary DPF pipes offered as part of the published scope.
- GPS lock resolution — deactivation of the GPS lock program in both the ECU and the monitor.
The Process, as Published
| Step | What happens |
|---|---|
| 01 — Machine information | The customer shares ECU/monitor photos and stickers, the machine nameplate and the engine nameplate. |
| 02 — Schedule | A time for the remote operation is agreed with Kyotechs. |
| 03 — Connect | A testing tool (ET, Inline 6, VCOM, IDSS or DX2) is connected to the machine. |
| 04 — Remote link | The remote software is installed and a secure connection established. |
| 05 — Remote operation | Kyotechs' technicians carry out the program installation or refit remotely. |
| 06 — Test on the machine | The ECU and monitor are installed on the machine for comprehensive testing. |
Hardware, when it is needed, comes from the documented catalogue: the controller page and monitor page list the units on record. Diagnosis of the underlying engine is covered by the engine repair solution, whose platforms are the same tools this service connects with.
Frequently Asked Questions
Do I have to ship my ECU to you?
Not for the remote routes. The published process connects a diagnostic tool to the machine and works over a remote link; shipping a unit is only involved where a replacement unit is supplied.
Can my existing monitor be reprogrammed?
Yes — reusing existing ECU and monitor units for program upgrades is an explicit part of the service, and it is the first route to price if your hardware is alive.
What information do you need to start?
Photos of the ECU and monitor including their stickers, plus the machine and engine nameplates. That set is step one of the published process, and it is what the enquiry reply will ask for.
Software or Hardware? Deciding First
The three routes in this service exist because software faults impersonate hardware failures. A controller that has lost its program looks dead; a monitor with the wrong program looks broken; an ECU locked by a GPS lock looks like a security write-off. Each is a software job with a working unit. The decision procedure is the published process itself: identify the units from their stickers, connect the diagnostic tool, and read what the system reports before pricing any replacement. Where the hardware is genuinely dead, the replacement route is quoted from the documented catalogue with its program state arranged for the machine — the two outcomes are priced separately so the customer can see what they are paying for.
