OFT FAQ

  • In a few words, what is the OpenFlash Tablet?
    It is a portable hand held flashing device with high-resolution backlit color touchscreen with internal speaker. It comes with a USB cable, OBDII cable and download links for the OpenFlash software (map manager), map editor (Tuner Pro) and XML definition files.
  • Are OpenFlash Tablet tunes actually free?
    Absolutely. All of our off-the-shelf (OTS) maps are free and available for download. We can offer free tunes because we are mainly in the business of selling tuning hardware/tools, not tunes. While we believe our OTS maps are excellent, we have no problem with giving them out for free. They are unlocked, fully viewable and completely editable using free tuning software (also for download).
  • Do I need a laptop?
    Since the OpenFlash Tablet comes pre-loaded with tuned files for your vehicle, there is no need for a laptop. The only time you would need a laptop is if the OFT doesn’t recognize your ECU software. In that case, simply connect the OFT to your laptop running our free user software (downloadable from the downloads section on this website). Then download your ECU file from your OFT and email it to us. With 24 hours, you will receive tuned files compatible with your ECU software. The only other time you may want to use your laptop is for periodic updates that are applied automatically from our remote server when your laptop has a wifi connection. A laptop is also necessary to load custom files that you (or your tuner) may want to load to your ECU. And lastly, a laptop is needed to download datalogging data (.csv file) from your OFT.
  • What is “open” ECU mapping?
    The term “open”, in the tuning world, refers to being able to have full access to the ECU’s ROM file. In the case of the MSD80/81, this ROM file is a 2.1megabyte binary (.bin) file that is stored in a memory location on your ECU. This file is where all the engine mapping data is stored. By “full access”, you are able to read, save and edit your original ROM file without any sort of encryption. You will also have full knowledge of table location (when defined in the .XDF definition file), its values and its scaling. There is nothing hidden or obscured for the sake of IP protection. Even the dealership won’t be able to easily tell if the ECU is modified since the software IDs are unchanged.
  • How many ROM files can the Open Flash tablet hold?
    At this time, the OpenFlash tablet can hold 6 ROM files with one of them being the original ROM file.
  • How many time can I flash my ECU?

    Theoretically, there is a finite limit as to how many times your ECU can be flashed. However, we have flashed our development ECU over 500 times without a hiccup. This should not be a concern to most users.

  • Can I read/clear codes?
    Yes, all ECU trouble codes can be read in hexadecimal format. A code look-up document is also provided for user convenience.
  • Can I disable codes?
    Yes, many common code toggles are defined in the current XML definition files. More can be found quite easily.
  • Can my tuner lock these maps so I can’t view them?
    No. These maps are not “lockable.”
  • Is a flash from this device detectable by the dealership?
    Each modified ROM file is based upon the original ROM. In this ROM file, you have all the mapping data and the software ID data. Typically, you will only ever want to modify the mapping data. Which means the software IDs will be untouched and stock-looking upon basic inspection. However, it is possible for the dealership to conduct a more thorough inspection of the ECU code. Which is why we recommend flashing the original ROM file back into the ECU at your own discretion.
  • Is the OpenFlash Tablet for advanced users only?
    No. It is for beginners and advanced users alike. There is no need to edit ROM files yourself if you are not comfortable with doing so. Instead, beginners can use the Tuning Wizard feature on the Tuner Pro map editing software to tune your ROM at a click of the mouse. Advanced users, on the other hand, can do just about anything. From modifying map data, changing load/rpm breakpoints, editing software calibration IDs, etc,. There is nothing but your own discretion keeping you from doing whatever you want to do.
  • Can I flash multiple cars wither the same device?
    No. Each OpenFlash Tablet can only flash the ECU of one car at a time. However, it can be “unmarried” from the car by flashing the original ROM file into the ECU and erasing the device contents. At which time, the device can be installed on a second car. But even when married to one ECU, the device and be used in Diagnostics mode in other vehicles. Diagnostics mode will provide individual adaptation resets, code reading/clearing, data view and soon, data-logging and data graphing.
  • Does the OpenFlash tablet offer data-logging?
    Yes, high-speed on-board datalogging is supported by the OpenFlash Tablet! On-screen data viewing and data graphing functions are also available, making the OpenFlash Tablet a powerful tooling tool. Datalogs can also be analyzed on your laptop using the www.datazap.me.
  • Are software updates free and how do I get them?
    Software updates are free and available by simply plugging the OpenFlash Tablet into your laptop while running the OpenFlash user software. Upon launching (with a wifi connection), the OpenFlash software will automatically check for software and firmware updates and apply them immediately. With each update, expect new features and bug fixes (yes, we are human!).
  • Will the OpenFlash Tablet work on a vehicles with a pre-existing Ecutek tune?
    We do no recommend trying to read and edit an Ecutek tuned ECU with OpenFlash Tablet. Instead, we suggest flashing your ECU back to 100% stock configuration using the Ecutek programming cable and the proceeding as normal. There is no longer any need for the Ecutek cable or license.
  • Do I need a battery charger?
    No battery charger is necessary since the read and write processes are so brief.
  • How do I install the OpenFlash Tablet?
    To install, you simply plug the device into the OBDII diagnostic port and follow the prompts. Within a few seconds, the Open Flash Tablet will initiate a read sequence. You only need to do this once. This process only takes 2 minutes. After this process is complete, the Open Flash Tablet will have saved your factory ROM file which will be available for you to view and edit as you see fit on your laptop computer. For safety, the OpenFlash Tablet automatically saves the original ROM file in a special read-only memory location. Which means that you can’t accidentally write over it.
  • How long does it take for the Open Flash Tablet to flash my ECU?
    At this time, each flash write takes 3-5 minutes. The Open Flash tablet writes the entire 1.3 megabyte file (1.0 megabyte file for Miata MX5).
  • Does the OpenFlash Tablet correct for checksum?
    Yes, when uploading modified/tuned ROM files into the Open Flash tablet, the Open Flash user software will automatically apply checksum correction.
