    Frequently asked questions

    How can I operate the file?

    Before you start

    • Cruise main switch must be on.
    • Engine must be on if you didn't change the "Reset prevention switch".

    Controls

    • Press and hold cruise down, then press up/down to switch maps.
    • Press and hold cruise cancel to switch to Quick Toggle map.
    • or
    • Press and hold brake, then press and release accelerator pedal to switch maps while holding the brake.
    My ECU is not bench flashable. Can it be recovered if something goes wrong with the file?
    Absolutely. We have added a "Reset prevention switch" which is on by default. After you have tested the file, you can turn it off and use Mapswitch with engine off. The address for the switch is provided in the document sent with the file.
    I need to adjust the timers to enter Mapswitch mode
    We will provide a document with the file for you to adjust parameters in the file.
    Do you offer any tuning or help with tuning?
    No, we specialize in tools for tuners and do not offer tuning. You can contact one of the registered tuners in our Tuner List.
    Are my tunes safe? How can I be sure you will not copy them?
    • We do not offer tuning services, nor do we have plans to enter the tuning market. We have been active software providers since 2020.
    • Tunes are never stored on the server; they are processed by the tools and the combined file is sent over email.
    • We do not need to know what hardware is installed in your car — any tuning file is worthless without that information.
    How can I use this tool without sharing my tune with you?
    Place a marker in the maps you changed instead — for example, a repeating number like 111111 at the beginning of a map. Our tool recognizes that as a signal to copy that map. Later in WinOLS you can search for the marker. Mappack/csv is not provided; define markers manually.
    What file format do you upload?
    • Bflash .bdc, KTAG .bin, MMS Flex .bin, CMD .bin have been tested. Dimsport full reads are also supported.
    • For Autotuner, first unlock the ECU for OBD flash, then read the file in bench, combine the iflash0/1 files, then submit.
    • Virtual reads are only supported if they have a code area. If your file has only calibration data, it cannot be patched.
    • Our tool will reject VR that does not have a code area. That does not mean the ECU is unsupported — it means the file is incomplete.
    What is the Quick Switch Slot?
    An extra slot outside the main slots rotation. Lets you toggle while driving — for example into a retarded ignition map — for Quick Toggle.
    What does Cruise Control Ethanol Adjust do?
    Adjusts fueling/lambda behavior with cruise control buttons according to ethanol blend. Ignition/boost/load control based on ethanol is planned for future updates.
    What does Live Ethanol Sensor Adjust do?
    Reads your ethanol content sensor in real time and adjusts fuelling/lambda in the active map accordingly. Requires a functional ethanol content sensor on drivetrain CANBUS, like Zeitronix ECA-2.
    Can I upload fewer than the maximum number of files?
    Yes. The minimum is 2 files. You do not need to fill every slot — upload only what you need.
    Can I reorder or replace files after uploading?
    You can change files anytime with unlimited updates for the same VIN.
    Who can see my files?
    Nobody. Files are handled automatically. A human only accesses them if you open a support request.
    What do I get back?
    A single merged binary file ready to flash. It contains all your uploaded maps with switching logic built in.
    Can I change my package after selecting one?
    Yes, before you submit. Use the "Change Package" link at the bottom of the order form or click the package name at the top.
