Custom ECU remapping, by hand Real files. Real gains. Real fast.

• Every remap is calibrated by hand

  Stage 1, Stage 2 and Stage 3 files are custom calibrated by the tuner on your own read, around your hardware and your software version. A remap is never delivered from a library.

• We change your read, not a template

  The file you download is the file you uploaded, byte for byte, apart from the regions that had to change. Nothing is rebuilt from a stock file and nothing is swapped for somebody else's.

• Automation only for simple solutions, on an exact match

  A solution on its own, such as EGR or DPF off, can be applied automatically, but only when the checksum of your read equals the checksum of a file the tuner has already done that work on. Not the same car, not the same software number: the same bytes. Every changed region is verified in your own file first.

• Ten checks, all or nothing, and your choice

  An automatic file is released only if all ten checks pass on the finished file, and a half-written file is never produced. Prefer a human on it anyway? Tick one box when you order and the tuner does the whole job.

• Stage 1

  Software-only remap on completely stock hardware, custom calibrated on your own read. The everyday gain, and the one most customers want.

• Stage 2

  For cars already carrying an intake, exhaust or downpipe. The calibration is written by hand around the hardware you actually have.

• Stage 3

  Built engines and upgraded turbos. Quoted per job, because no two of these are the same car.

• DPF and EGR

  Particulate filter and exhaust gas recirculation solutions. Off-road, motorsport and export use only.

• AdBlue and SCR

  AdBlue and SCR system solutions for trucks, agricultural and commercial vehicles. Same terms of use.

• DTC delete

  Clear a specific stored fault code from the calibration once the underlying cause is understood and handled.

• Vmax, pops and launch

  Speed limiter removal, overrun crackle and launch control on platforms that support them. Ask first if you are unsure.

• Gearbox (TCU) tuning

  BMW 6HP and 8HP, GM 5L40E (GS20), Mercedes 722.6, VAG DSG and S tronic, and the 8HP in other makes. Calibrated by hand. Anything else, just ask.

Emissions equipment solutions are supplied for off-road, motorsport and export use only.

1. 01

   Find and upload

   Pick your engine out of the database, read the ECU with your tool, and upload the original file to your account.

2. 02

   Calibrated for your car

   The tuner calibrates your remap by hand on your own read. A simple solution on its own, such as EGR or DPF off, can come back in seconds on an exact match, and one tick sends that to the tuner too.

3. 03

   Download and drive

   The finished file lands back in your account, ready to flash. Questions go in the job thread and come straight to the tuner.

• Files come back fast and spot-on. The engine database alone saves me so much time finding the right variant. Support is top notch.

• Proper custom work, not off-the-shelf files. Someone knowledgeable actually answers when I have a question.

• Ordering through the portal is effortless. Pick the engine, select the modifications, done.

• Is Remapify a file database or a tuning service?

  A tuning service. Remapify is not a download site: there is no archive of stock ORI files, DAMOS or ready-made tuned files to browse or buy. You upload the master read from your own ECU, and every Stage 1, Stage 2 and Stage 3 remap is custom calibrated by the tuner on that read, for your hardware and your software version. The vehicle database is there to identify your exact engine before you order, not to hand out files.

• Are any files automated, and can I opt out?

  Only simple solution work, and only when you order it on its own: EGR, DPF or AdBlue off and similar. If the checksum of your read exactly matches a file the tuner has already done that same work on, the portal applies it and runs ten checks on the result, which can return it in seconds. Remaps are never automated. If you would rather a human handled a solution-only order too, tick one box when you submit and it goes straight to the tuner.

• What kind of ECU file do you need?

  A master file: an open, unencrypted read taken from the ECU with your own tool. A slave read can only be worked on if your slave tool is slaved to Remapify, so contact support first. A slave read belonging to another tuner is encrypted to them and cannot be opened. Full, partial and virtual reads are all accepted, and the upload limit is 50 MB, which is comfortably above a full read from a modern ECU.

• Which tuning tools do you support?

  All master tools are supported, and slave tools are supported too as long as the tool is slaved to Remapify: contact support and we will help you set it up. The submission form lists Autotuner, KESS3, KTAG, MPPS, CMD Flash, Trasdata and New Trasdata, Dimsport New Genius, FoxFlash, PCMFlash and Magic Motorsport Flex, and there is an Other option for anything not on that list. File names and extensions do not matter, the file is checked by its contents.

• Do I get a generic file, or do you modify my own read?

  Your own read, and never a generic file. Every remap is custom calibrated by the tuner on the file you upload, and the file you download is that same file, byte for byte, apart from the regions that had to change. The only automatic path is a simple solution ordered on its own, and even then the checksum of your read has to equal the checksum of the file the tuner originally did that work on, and every region being changed is verified in your file before a single byte is written.

• Do you need my ECU software number?

  We take the ECU from the vehicle database when you pick your engine, and if that engine ships with more than one ECU you tell us which one, or say you are not sure rather than guessing. What identifies the file is the read itself: the tuner calibrates from the actual software on it, and an automatic solution file is matched on a checksum of the actual bytes, which is a stricter test than a software number because two files can share a number and differ.

• What checking happens before a file is released?

  A remap is calibrated and checked by the tuner, and goes out under the tuner's own judgement. An automatic solution file gets ten checks on the finished file: the original content of every modified region has to be present in your file, the size has to be unchanged, changed regions may not overlap or fall in a protected area, and the file has to differ from what you sent. It is released only if every check passes, and a half-written file is never produced.

• How long does a tuning file take?

  A remap is calibrated by hand, so it takes as long as the work does, and you are kept updated in the job thread on that order. A simple solution ordered on its own, such as EGR or DPF off, can come back in seconds when your exact read matches a file the tuner has already done that work on, and is checked before it is released.

• Is checksum correction included?

  Most current tools correct checksums as they write, so on a normal job that is where it is handled and there is nothing for you to add. If yours does not, add the Checksum option when you order, or just ask in the job thread and we will sort it. That same option also covers a file that was modified somewhere else and arrives with its checksums broken.

• What if the car does not run right on the file?

  Tell us in the job thread what the car is doing, with logs if you can take them, and the file is reworked at no extra cost within 30 days of delivery. The thread stays open on every job, including after it is closed, so there is always somewhere to raise it and it goes straight to the tuner.

• Do you tune gearboxes (TCUs)?

  Yes. We tune every BMW ZF 6HP and 8HP, the GM 5L40E with its Siemens GS20 control unit, and the Mercedes-Benz 722.6 with the Siemens EGS52 or EGS53, the common VAG DSG and S tronic gearboxes, and the ZF 8HP in Jaguar, Land Rover, Dodge, Jeep and other makes. Shift times, pressures, scheduling and torque limits are calibrated by hand from your own read. A TCU tune is not required with an ECU remap, but it is recommended whenever the engine is tuned.

• Can I convert a TunerPro XDF to a WinOLS map pack, or a KP to XDF?

  Yes. The mappack converter in your account turns a TunerPro XDF, a WinOLS map pack (.kp) or a WinOLS CSV into any of the others, including a map pack WinOLS 2.24 can open. Upload the file and see what is in it for free, and pay credits only for the file you download. No KP or XDF to start from? We can make a map pack or XDF for any ECU, quoted per request.

• What is the difference between Stage 1, Stage 2 and Stage 3?

  All three are custom calibrated by the tuner on your own read. Stage 1 is a software-only remap on completely standard hardware, which is what most customers want. Stage 2 is written around hardware you have already fitted, such as an intake, exhaust or downpipe. Stage 3 covers built engines and upgraded turbos, and is quoted per job because no two of those cars are the same.

• Do you supply DPF, EGR and AdBlue solutions?

  Yes, for off-road, motorsport and export use only. There is one restriction we enforce in the software rather than in the small print: emissions equipment solutions are not sold to private individuals in Finland, only to trade customers. Everywhere else they are ordered like any other solution, and the terms of use still apply.

• What vehicles do you cover?

  Cars, vans, motorcycles, trucks and agricultural machinery. The vehicle database carries over 10,000 engine variants, so you pick your exact engine rather than a rough model match before anything is uploaded.

• What if my vehicle is not in the database?

  You can still order. The submission form has a My vehicle is not listed option that lets you type the details in by hand, and there is a report link on every engine page. Missing entries and corrections are added continuously.

• Who can open an account?

  Signing up is free and takes a couple of minutes, and every account is reviewed by the operator before it is activated. This is a trade portal, so tell us who you are and what you work on when you apply.

• How does payment work?

  You buy credits with a card through Stripe, and each job spends credits from your balance. Card details are entered on Stripe's own checkout and never touch our site. Every purchase produces an invoice you can download from your account. Refund terms are in the Terms of Service.

• Is my file kept private?

  Yes. Files are held in private storage, never in a public bucket, and are readable only through your own account. Two-factor authentication is required on every account, with an authenticator app or emailed codes. Nothing you upload is shared with anyone else.

• Who is behind Remapify?

  Remapify is run by a working tuner in Finland, operating as Ainamotive Oy. Files are written and tested in Finnish conditions, which is a harder test of a cold start than most places give one. Questions in a job thread come straight to the tuner, not to a call centre.
