Built-in Engine
Checksum correction now happens inside the platform, in a separate tab — no external tools needed. Upload your file; the system detects the ECU, applies the required correction itself and returns only your own file with the checksum fixed.
Browser-Based Map Editor
No installation, no licence dongle — your file is open the moment you sign in. Hex, 2D and 3D editing, ready-made mappacks and an automatic DTC module in one screen.
Membership & Packages
Pick a package for your vehicle type — PrimeChecksum is included in every package, no extra fee. Credits are spent per job; no credit is charged when no result is produced.
Flow
Safe output in four steps.
Upload your original ECU file — the system detects the vehicle and ECU and shows the match rate.
Only genuinely applicable solutions (DPF / EGR / Stage…) are enabled; the rest stay dimmed.
The solution is applied to your file safely — it won’t break it; credit is refunded for any undeliverable job.
Download the output. If a checksum is needed, fix it with PrimeChecksum in the Checksum tab, then flash safely.

Yes. Our built-in PrimeChecksum engine fixes the checksum for you in a separate tab. Upload your file — the system auto-detects the ECU (148 ECUs), asks for the original if needed, and returns only your own file with the checksum fixed. Credit is charged only once the result is ready.
