Instant ECU tuning files, Stage 1 to Stage 3
Upload the stock read from your ECU, pick the stages and deletes you need, and download a checksum-corrected tuning file. Processing is automatic and runs around the clock, so a typical file comes back in under a minute — no ticket queue, no waiting on a tuner to come online.
- Stage 1, Stage 2 and Stage 3 calibrations
- DPF, EGR, AdBlue/SCR, DTC and more
- Checksum-corrected and flash-ready
- See every option and the price before you pay
How it works
- Upload your read Drop in the original file you read from the ECU. We decode it, identify the control unit and match it against our project database.
- Pick the services you need Choose your stage and any additional options. Each one shows its credit cost up front, so the total is never a surprise.
- Download the result The finished file is checksum-corrected and ready to write straight back to the vehicle with your existing tool.
What an ECU tuning file actually changes
A tuning file — also called a remap, a chip tuning file or a calibration — is a modified copy of the software your engine control unit runs. Boost pressure, injection quantity and timing, torque limiters and the throttle map are all stored as tables inside that software. Rewriting them is what turns a factory calibration into a Stage 1, Stage 2 or Stage 3 map.
The file we return is the same format you read out, with the modified tables written back in and every checksum recalculated. That last part matters: an ECU that fails its internal checksum test will refuse the write or throw a fault, which is why a checksum-corrected file is the difference between a job that flashes first time and one that does not.
- Stage 1 — a calibration for an otherwise standard vehicle
- Stage 2 — for cars with supporting hardware such as an exhaust or intake
- Stage 3 — for heavily modified builds, matched to the parts fitted
- Individual options — deletes, limiter changes and drivability tweaks
Supported ECUs and control units
The platform covers the control units that make up the bulk of the European parc — the Bosch EDC and MED/MG families in particular, across both petrol and diesel. If your read comes from one of these, there is a very high chance we already hold matching projects for it.
- Bosch EDC15, EDC16, EDC17 (including C74 and C76)
- Bosch ME7, MED9, MED17, MEVD17
- Bosch MG1 and MD1 (MG1CS001, MG1CS003, MG1CS011, MG1CS111 and related)
- Siemens/Continental SID, SIMOS, MSD and PCR families
- Delphi DCM, Marelli MJD and IAW, Denso, Temic/ZF transmission units
Which files we accept
Master files are accepted directly — .bin, .ori, .mpc and the other common read formats. If your file came off a slave tool it is encrypted, and it has to be unlocked before it can be edited: either run it through our crypt/decrypt service, or link your device to us so we can work with it in its native container.
If we cannot match your read automatically, the job does not simply fail. You can request manual processing and our team handles the file by hand.
