From an original file to a validated MapPack
Automatic map detection
Map Decoder locates and identifies the calibration tables inside the ECU binary automatically — no manual hex hunting.
ECU file analysis
Detect the ECU family and fingerprint, and compare original vs modified files before you commit a change.
Patch generation
Apply validated modules — EGR, DPF, AdBlue, Lambda, NOx, DTC removal, Stage 1/2 — with one click.
Automatic checksum correction
Checksums are recalculated automatically so the modified file is accepted by the ECU.
Broad ECU coverage
Bosch, Continental, Delphi, Siemens, Denso and Valeo — EDC16, EDC17, MD1, MG1, SID, DCM, MED, PCR, MEVD.
Fast pipeline
Upload a file and receive a MapPack output within minutes, with AI plus human validation in the loop.

ECU tuning software — frequently asked questions
What is ECU tuning software?
ECU tuning software lets you read, analyse and modify the calibration data inside an Engine Control Unit. Map Decoder adds automatic map detection and a validated patch engine, so you can produce a ready-to-flash MapPack without editing maps by hand.
Is ECU tuning with Map Decoder safe?
Every file passes AI plus human validation and automatic checksum correction before output, which minimises the risk of a rejected or unstable flash. The user remains responsible for legal and road-use compliance.
How is Map Decoder different from WinOLS?
WinOLS is a manual map editor. Map Decoder automates the same core workflow — map detection, comparison, patching and checksum correction — with an AI-assisted pipeline and a validated patch catalogue.
Which ECUs does it support?
Bosch, Continental, Delphi, Siemens, Denso and Valeo ECUs, across families including EDC16, EDC17, MD1, MG1, SID, DCM, MED, PCR and MEVD — 35+ brands and thousands of models.
