Automated chiptuning · RemapCloud Studio
Online ECU Remapping Software with a Map Editor in Your Browser
RemapCloud is automated chiptuning software that runs in your browser. Upload your file, see applicable operations in the free pre-check, apply your selection and download the result. For manual map editing, use the Hex, Table, 2D and 3D views in Studio. Checksum is handled in a separate RemapChecksum tab; not every operation is available for every file.

What it does
Identifies → Applies → Edits
You work on your own ECU file, read from the vehicle with your own tool.
Identifies
Identifies the ECU from the file itself; when it is recognised, you do not need to pick a make or model from a list. If it is not recognised, the panel asks you to select the vehicle type, make and ECU yourself. The pre-check is free: you see the operations that apply to your file without spending credits.
Applies
Only the verified solutions from the library that genuinely apply to your file are enabled. The solution is verified at byte level as it is applied; if one of your selected operations cannot be applied, the file is not delivered and the credit is refunded.
Edits
RemapCloud Studio: Hex, Table, 2D and 3D view; potential map finder, ORI/MOD differences list and compare, undo/redo, saved versions and the Ctrl+K command palette — in the browser, no installation.

Operations
Supported operations
Each operation page lists the ECU families and vehicle types that support it.
Operations on emission systems are offered only for use permitted by local law (e.g. off-road / motorsport / export); responsibility lies with the user.
RemapChecksum
Checksum and the honest limit
Inside the platform
The ECU is detected from the file and the original is requested when needed; the output is only your own file and your tune is preserved.
The honest limit
Checksum correction happens inside the platform, in a separate tab: 1 credit, charged only when the result is ready. Some newer-generation ECUs (RSA-signed) need an external tool; the system detects this and warns you.

Pricing
Price summary
A module job costs 1 credit (any number of modules in one job); Stage 1 costs 2 credits for cars/bikes and 3 credits for trucks, tractors and construction machines. With Stage 1, each module you add costs +1 credit (Stage 1 + 1 module: 3 credits for cars/bikes, 4 credits for trucks, tractors and construction machines). No credit is charged for a job without a result. A package is bought once and renewed every year with the annual licence. Prices exclude VAT.
Let the program apply it instead
If you would rather not edit maps, the program applies the verified solution from the same library to your file; you download the result from your panel.
What should good chiptuning software do?
Six criteria — correct file identification, refusing unfit files, credit refunds, honest checksum status, range of operations and support — and what RemapCloud does on each.
Got an Autotuner, Flex, KESS3 or Dimsport file?
How the file you read with your tool is uploaded to the software: which file, which formats, full and partial reads, encrypted slave packages and the checksum before writing.

Questions
Frequently asked questions
What is chiptuning software, and which programs are used?
Chiptuning software is used to edit the software file read from an ECU. Three kinds are common: desktop map editors, editors that run in the browser and file services that process the file for you and send it back. RemapCloud combines the automatic solution with a browser editor: it identifies your file and applies the verified solution, and you can edit the maps yourself in RemapCloud Studio.
Do I need an installation or a dongle?
No. RemapCloud Studio runs in the browser; no installation or licence dongle is needed. Log in with a free account and upload your file.
Which reading tools are compatible?
The system looks at the file itself, not the reading tool: upload the original (raw) file read from the ECU and the ECU is identified from the file. KESS3, Autotuner, FLEX and similar names are trademarks of independent manufacturers; RemapCloud is not their dealer or representative; we provide solutions for files read with these tools.
Do you correct the checksum?
Yes. Checksum correction happens inside the platform, in a separate tab: 1 credit, charged only when the result is ready. Some newer-generation ECUs (RSA-signed) need an external tool; the system detects this and warns you.
How much power does Stage 1 add?
Typical range by engine type — Turbo diesel: power +20–30%, torque +25–35%; Petrol (turbo engines): power +15–25%, torque +15–25%; Diesel (heavy-duty): power +15–25%, torque +20–30%. The horsepower figure depends on the vehicle's stock output. Gains vary by vehicle hardware and file; typical ranges are indicative.
How is the price calculated?
A module job costs 1 credit (any number of modules in one job); Stage 1 costs 2 credits for cars/bikes and 3 credits for trucks, tractors and construction machines. With Stage 1, each module you add costs +1 credit (Stage 1 + 1 module: 3 credits for cars/bikes, 4 credits for trucks, tractors and construction machines). No credit is charged for a job without a result. A package is bought once and renewed every year with the annual licence. The pre-check is free.
What if my file is not recognised?
The panel asks you to pick your vehicle yourself: vehicle type, make and ECU. If the library solution for the ECU you picked fits your file, the operations open; if it does not, they stay closed. This analysis does not use credits. If no applicable operation comes up, you can open a request in the Support & Requests tab of your panel and attach your file.
Is chiptuning legal?
It depends on the country and the intended use; complying with local law is the user's responsibility. The condition for operations on emission systems is stated in the note under the operations section.
