MULTIMAP MED17/EDC17

Switching is done using the Android / iOS application "TuningHost" and the diagnostic device ELM327 Bluetooth.

All branded ELM327 Bluetooth devices are supported. However, please be aware that low-cost, unbranded ELM327 devices may not be compatible. We recommend:

• • UniCarScan  (Android / iOS)
  • iCar Pro 2S   (Android / iOS)
  • vLinker BM+ (Android / iOS)
    You can also read an excellent article about ELM327

• WiFi ELM327 devices are NOT SUPPORTED!
• We do not sell diagnostic scanners. You need to purchase ELM327 yourself.
• Dashboard indication, switching using cruise control, custom boost pre-control, etc. are not supported in this service as it requires additional changes to the firmware code.

Some modes can be activated simultaneously, allowing you to combine Power, Fuel Type, Sound, Eco and more.

Switching to Stock mode is fully complete, i.e., not only some maps are switched, but all of them, meaning the engine will run on the completely factory program with only one exception: 

in most cases, in Bosch MED17, the torque monitoring area (a small area located at the beginning of the calibration data) will not be switched(as this can cause checksum problems) and will remain common for all modes. This normally does not affect the vehicle's behavior. All other maps will be switched.

Why App and not cruise control?

Cruise control, the combination of pedals, and similar features do not offer the same level of convenience as our app. The obvious advantage of cruise control or pedals is their constant availability in the car and quick response, as no connection is required.

Connecting to a BLE (BT4.0 - ...) device takes 0.5–1 second, followed by another second to initiate communication with the car and retrieve the available and activated modes. Switching modes takes another second, including deactivating the anti-theft system, etc. Many modes can be switched while driving, which is nearly impossible with pedals or even cruise control in many cars. Moreover, the anti-theft system uses 8 hexadecimal (0-9A-F) values instead of 4 decimal ones, making it virtually impossible to guess such a code in a reasonable time (months), especially considering protection against brute-force attacks. The ELM327 can remain in the OBDII port since most devices sleep when no CAN Bus message is received, thus not draining the car's battery.

On the other hand, the phone has become an indispensable accessory, and it’s unlikely anyone would go for a jog without their phone, let alone on a car trip. What if the phone runs out of battery? The counter-question would be: what if the cruise control or brake pedal fails? A phone or tablet can be charged, or you can use any other device, even a MacBook. Cruise control and brake pedals are less common, and in such cases, you’re more likely to end up calling a tow truck if the anti-theft system is activated.

We believe there’s no point in comparing indicators like the Check Engine light or a tachometer needle with a mobile device screen. A nice bonus of the app is its ability to read, save, and erase fault codes.

There are three scenarios:

1. You send us Stock +  tuning versions.

• • • Read the file on the BENCH or in BOOT mode. OBD or decrypted files (like .frf => .odx => .bin) are NOT SUPPORTED!
    • Modify the file. Name the versions as Stage1, E85, Cat, Exhaust, etc.
    • Send us the stock(original) file(incl. eeprom) along with the modified versions.
    • We will merge them into one Multimap file.

2. Tuning, E85 mode, etc. are done by us. In this case, the price will be higher.

        3. You can use markers. 

Please do not send us the names of the maps you would like to add since we do not need it.

If two engine control units (Master/Slave) are installed, you need to provide the firmware from both units. The Multimap file name will include the processor number, which indicates which unit the firmware is for. Slave does not affect the price.

For self-employed clients and companies, discounts of up to 75% are available when purchasing an average of 3 files within 6 months. The number of maps does not affect the price and is not of significant importance. The only limitation is the available space in the firmware.

The more files you buy, the lower the price:

1. The first file costs 420 EUR* (VAT 19% excluded)
2. The second file costs 210 EUR* (VAT 19% excluded)
3. 105 EUR* (VAT 19% excluded)
4. 105 EUR* (VAT 19% excluded)
5. 105 EUR* (VAT 19% excluded)
6. 105 EUR* (VAT 19% excluded)

After purchasing first 6 files within 6 months, you get 4 files for free. This effectively refunds the overpayment from the first two files (420 EUR and 210 EUR).

1. Free of charge
2. Free of charge
3. Free of charge
4. Free of charge
5. Each next file costs 105 EUR* (VAT 19% excluded)...

If you do not order files for more than 6 months, the pricing will reset to the initial rates (420 EUR, 210 EUR, 105 EUR).

* Exceptions: 

• Sports cars: Audi RS, Mercedes AMG, Alfa Romeo QV etc.
  • 1. 420 EUR (VAT 19% excluded)
  • 2. 350 EUR (VAT 19% excluded)
• Supercars: Ferrari, McLaren etc.
  • 800 EUR (VAT 19% excluded)

• We recommend PCM Flash Module 71 as it has settings, particularly for disabling checksum calculations, it does not erase the bootloader area or split files into PFLASH0, PFLASH1, etc.
• CMD users have to merge and export the file or files if there is external flash from the backup. The multimap can be flashed normally. CMD will automatically detect if it's a full file and flash it accordingly.
• Autotuner users have to send the Backup. It is extremely inconvenient for us to work with files read by this flasher.

Since the empty space in memory is limited depending on the manufacturer, normally there can be from 2 to 10 modes

You can make modifications of maps of different modes later on. We do not provide descriptions of maps, A2L, etc.

The cost includes checksum calculation if required.

• Many flashers incorrectly calculate the 16-bit checksum in certain software versions when additional code has been patched. In particular, CMD and PCM Flash have this issue, Autotuner does not calculate CRC in full files at all. WinOLS calculates it correctly.
• Checksum calculation for certain software versions that include multiple calibration areas (CAL) is also available. WinOLS and many flashers do not calculate such a checksum for the monitoring area. PCM Flash does.

The firmware is individual, modified only for a specific control unit and cannot be used in another control unit, even with the same software and hardware numbers.

If you need it, you can edit the software numbers in flash and in eeprom in this specific ECU.

Around one minute if you send us the versions (Stage 1, E85, etc.).

Support is available only through WhatsApp chat or email in English. We do not provide free support for reading and writing firmware, diagnosing the engine, analyzing logs, etc.

• To our bank account without fee.
• To PayPal account 5% fee.

After successfully verifying the file, we will issue an invoice to you.

We will permanently terminate cooperation with you or/and your company if the following terms of use of the service are violated:

• Collusion of firmware is prohibited. If we find a thread on the forum, Facebook, etc. that such collusion was organized by you or you participated in it, this constitutes a violation of the terms of service.
• Posting firmware on forums, Facebook groups, Telegram, etc. is prohibited.
