ECU file service for shops & DIY tuners

Send a read from any tool, get a file back. Every job is a ticket: the vehicle, the files and the conversation in one thread, with every revision versioned.

Tune files

Stage 1, Stage 2 and custom calibrations from a stock read, built against the customer's hardware and fuel.

Checksum correction

Your changes, our checksum repair. The families we support are computed on our own tooling.

File repair

A file that won't flash, won't start, or throws codes. We diagnose what's wrong and fix it.

Custom & unusual ECUs

Controllers other shops can't work on. If it has a bus and a binary, we can usually map it.

Pricing

  • Stage 1 — Stock or bolt-ons. One revision included.$399
  • Stage 2 — Downpipe, intake, intercooler. Your fuel target.$599

File service questions

What file formats do you take?

Plain binary reads from any tool. If your tool wraps the read in its own container, send it anyway and tell us which tool — we'll ask if we need something else.

Do you do checksum correction only?

Yes. If you've made your own changes and need the checksums fixed, open a ticket with the file and the ECU — we'll quote it there.

Can you fix a file another tuner built?

Usually. Send the file, the stock read if you have it, and what's wrong. We'll tell you what we see before you pay for anything.

How do revisions work?

Each tier includes revisions. After that, a revision is $99. Send logs in the same ticket and we work from them.

Do you do emissions deletes?

No — not on road vehicles and not on farm equipment.
