How TCEPro works

Six steps from creating an account to editing ECU maps on this PC — and what to expect once access is granted.

Create account — Email and password, or Google.
Sign in to TCEPro — Same account. The installer is available from Download after you sign in.
Buy a catalog — From a dealer, one catalog at a time, with the email of this account.
License turns on — With your first catalog. Each catalog you buy is added to the same license.
Catalog downloads — Bound to your license and device slot.
Work offline up to 3 days — Warning in TCEPro until the signed lease expires. Then sign in again.

Inside TCEPro

After purchase the catalog opens in the project workspace — tables, compare and offline projects, licensed to this PC.

Maps, projects and the licensed catalog — one desktop app.

Several maps open at once — tables, a chart and the map list.

Fault codes beside the catalog — Errors (DTC) in the map list.

What working in TCEPro looks like once access is granted.

Sign in and download catalogs — First time only: open Map Catalogs and download what you are entitled to.
Open a firmware file — Drag a .bin, .rom or .mod file into the window — the map tree appears on the left.
Find the map — By name or color tag; open its table and chart.
Edit with undo — Cell by cell, in bulk or by smoothing. Every change is remembered and can be undone.
Compare if needed — See the differences against a second firmware and carry them across in one action.
Export and flash — Export to a new file with checksums recalculated for supported families, then program the unit with your usual equipment.
