Vishnu Openflash Tuning Table Tablet (OFT V2)
Posted by Sean Grey on 24th Apr 2018
I ordered the OFT for my uel headers to run the stage 2 tune when they get installed, but I have been running the stage 1 out of curiosity. It is insane how much the car has changed just with the base stock tune. Watching videos on how to really utilize the tablet shows how easy it is to actually use it to its full potential. Highly recommend, and when I used this month's coupon, I essentially got free two day shipping. (Delivered the next day for me)
Only drawback I had was no preloaded tunes, but it is relatively easy to figure it out.

The oft is great the only thing that sucks about it now is that the rotate option isn’t available but it is coming since i talked to shiv about it and my didnt come preloaded with the tunes. i put them myself but that was pretty straight forward. great product overall and better build quality than the first version.

OPEN FLASH TABLET 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.
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.
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.
How long does it take for the Open Flash Tablet to flash my ECU?
At this time, each flash write takes just under 5 minutes. The Open Flash tablet writes the entire 1.3 megabyte file.
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.
Do I need a battery charger?
No battery charger is necessary since the read and write processes are so brief.
Will the OpenFlash Tablet work on a BRZ/FR-S with an 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 the Off-The-Shelf (OTS) maps incorporate the Direct Injector seal update/fix?
Yes. All OTS maps are based upon the newest factory software calibration with DI seal fix. So even if your ECU current has an old software version (without DI seal fix), flashing your ECU with any of our OTS maps will provide the fix.
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!).
How many ROM files can the Open Flash tablet hold?
At this time, the OpenFlash tablet can hold 3 ROM files with one of them being the original ROM file. This will change eventually as we continue to develop this product. Each ROM file is 1.3 megabytes and the total storage capacity on the OpenFlash Tablet is 256 megabytes. So plenty of room to grow while still leaving sufficient storage for datalog files.
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 with our free datalog viewer (downloadable from our website).
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.
Is this 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 make a clone ECU using the OpenFlash Tablet?
We have not attempted to do this yet given the cost of a ECU. But this will be tested soon.
What other development tools are coming in the future?
Expect a built-in CAN bus sniffing function eventually.
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.
Can my tuner lock these maps so I can't view them?
No. These maps are not "lockable".
Why is this device so inexpensive? Is it bad?
We have full time jobs. We are doing this on the side. So we aren't looking to do much more than cover our hardware costs, risks and time. If the price appeals to you, fantastic. If it doesn't, then there are other mighty fine options on the market for you to choose from!
Can I disable codes?
Yes, many common code toggles are defined in the current XML definition files. More can be found quite easily.
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.
>How many tables do I have access to?
At current count, you will have access to well over 200 tables. More will come as more users dig into the ROM.
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.
