Tool comparison
MTX DTC Remover is a classic desktop utility used to search and disable P-code Diagnostic Trouble Codes in older Bosch EDC15/EDC16/MED9, Marelli and Siemens ECU binaries. Because it only handles DTC tables on older vehicles, modern workshops use Softechpro Solutions to handle 9,415+ DTCs alongside DPF, EGR, AdBlue, Stage 1–3 and automatic checksum correction on 1,691+ modern ECUs.
"Volta" refers to automatic ECU-file solution software of the type used to apply common tuning-file modifications, including diesel emissions edits (DPF, EGR, Lambda) and DTC fault-code removal, with automatic checksum correction after each change. The intended workflow is to load a supported original read, choose the desired operations, and export a corrected file rather than editing maps by hand. Such software targets workshops and file-service technicians who want repeatable, one-click solutions on supported controllers, typically covering widely used Bosch and Siemens/Continental diesel ECUs. As with any automatic solution, coverage is defined by a supported list, and results depend on the specific ECU. Emissions-related deletions are restricted to off-road, motorsport, or export use in many jurisdictions.
MTX DTC Remover (Emissions Tool (DPF/EGR/AdBlue), MTX Electronics) and Volta (Emissions Tool (DPF/EGR/AdBlue)) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.

Whichever you flash with, Softechpro Solutions auto-applies DPF/EGR/AdBlue/DTC-off modules and Stage patterns with automatic checksum correction across ~1,400 firmwares on Windows & macOS — the fast way to get the actual file edits done.
