Compatibility

Current focus is supported Mercedes-Benz M157 applications using Bosch MED17.7.3, including compatible CLS63, E63, S63, ML63, and GL63 variants.

Exact support is ROM-specific. ECU software versions, table addresses, definitions, and checksum coverage can differ. Confirm compatibility before purchase when your ROM is not already supported.

The supplied releases include separate 32-bit and 64-bit builds for supported Windows 10 and Windows 11 systems.

Lifetime product access

The purchase is a one-time lifetime license for M157 Calibration Studio, including lifetime applicable updates for this software line. Additional definitions, compatible ROM support, Quick Commands, and workflow improvements are planned as the customer community grows.

This license is separate from EvoPro ROM Tool and does not include the Mitsubishi product.

Full XML service — $300 USD

For a supplied compatible ROM that needs a complete custom definition, the flat-rate XML service includes the confirmed tuning parameters, tables, thresholds, maps, X/Y axes, addresses, scaling, dimensions, categories, and relevant calibration areas that can be properly identified.
