Getting Started with the OpenFlash Tablet

Step 1: Read and save your DME software. You only do this once when you first install your OpenFlash Tablet.



Note: E90 (Sedan) owners should select E91, E92 or E93 when selecting their Vehicle Type. Erroneously, there is no 335i option for the E90 chassis in the OpenFlash Tablet interface. This is a known issue and will be resolved soon.


Step 2-7: Download your original ROM file from your OpenFlash Tablet to your Laptop and Use TunerPro to create your tuned ROM.

For those who don't like watching videos onine, below are written instructions covering Steps 2-7:
Step 2: Install and launch the OpenFlash Manager software on your computer. When it is running, the status window will say "Connecting to Device":

Connecting to Device


Step 3: Connect your OpenFlash Tablet to your laptop with the supplied USB cable. Make sure your OpenFlash Tablet is disconnected from your vehicle's OBDII part as it will not communicate with two devices at the same time. At this time, the OpenFlash Manager may apply some updates to your OpenFlash Tablet. This can take up to a 30 seconds. After updates are completed, you will see the following screen:

Step 4: Now you will download and save the DME file from your OpenFlash Tablet to your computer. This is a one-time only thing. Go to the Download Data menu. It may take up to 2 minutes to extract the DME file data from OpenFlash tablet. Once done, you will see this window with "Original File Present" near the bottom. Please note that your DME software version (IJEOS, I8AOS, etc,.) will be displayed next to "ECU SW":

original present

Click on the disk drive icon to save your original DME file to your laptop. Name it "Original ROM." We recommend creating a new folder called "OpenFlash ROMs" in which to save the file into. When you save your original DME file to your laptop, you may get an error message saying "Checksum is incorrect." This is normal and nothing to worry about.

Step 5: Download both the TunerPro Tuning Software and Off-The-Shelf (OTS) Maps from our website. Both download folders will need to be unzipped. Install and launch TunerPro software. This is the software you will use to edit and create your maps. Go to File->"Open Bin" and select your original DME map file that you saved in the previous step. Then go to XDF->"Select XDF" and select the appropriate XDF file (IJEOS, I8AOS, etc,) that you downloaded. Next, go to "View By:" and select "Parameter Category". To confirm that you selected the proper XDF file for your DME software type, go to Fuel->Fuel (Bank 1). It should look something like this:

correct XDF

If you have loaded the incorrect XDF file, you it will look strange. Perhaps something like this:

incorrect xdf


You MUST use the correct XDF file or you will not be able to generate functional tuning maps. If your ROM type is unsupported, please email it to openflashsupport@vishnutuning.com along with your ECU SW type as seen in your OpenFlash Manager screen (or on your Tablet screen, under DME Info, when plugged into your vehicle).


Step 6: To apply one of our Off-The-Shelf (OTS) tunes to your original ROM, simply double-click on the "Stage 0 (or Stage 1) OTS" parameter at the bottom of the parameter tree, click on "Apply Patch" and then click on "Apply". This will automatically transform your original ROM into one of our OTS baseline maps.

To confirm that the changes have been applied to your map, go to Limits->Torque Max (Index Array). If the tuning changes applied properly, all the values in the table should be equal to 110 like this:

max torque array 110




Step 7: Next, go to File->Save Bin and rename and save your now modified ROM file (i.e., Joe Stage 0/1/etc,). With the OpenFlash Manager software, click on "Upload Data". After approximately 30 seconds, you will be allowed to upload up to two different tuning maps on to your OpenFlash Tablet. After uploading each map, you will see an alert message saying that "Checksum has been Corrected." If you are running on Windows 8, you may see some nonsensical messages as well. You can ignore this. It will be corrected in the near future. Once you select the map(s) you want to load, scroll down to bottom of the window and click "Start". At this time, the map(s) you loaded will be saved to the OpenFlash Tablet. This process can take up to 1 minute.

Once the uploading process is complete, the message "Data has been written" will appear. At this time, you can disconnect the OpenFlash Tablet from your computer and plug it into the OBDII port of your vehicle.

Step 8: Programming your DME.



Note: During the writing/flashing process, it is extremely important that you have your ignition fully ON. You can tell this by looking at your fuel gauge. If ignition is fully ON, it will show a valid fuel level reading. If your fuel gauge reads 0, you are on accessory power which is not sufficient for the flash process. Also, during the writing/flashing process, you may hear your fuel pump whine. This is perfectly normal. It will turn off once the process is complete.

Step 9: Upon start-up, your vehicle should exhibit no strange behavior. If you experienced slow (or no) cranking, it is possible that your battery is very weak and was not able to hold up to the voltage demands of the DME flashing process. It is recommended that you get a new one. Vehicles with 6AT will trigger a transmission fault code upon start you. This will cause an SES light to illuminate. This is normal post-flash behavior and nothing to worry about. The light will clear after 4 engine start/stop cycles.

Boost pressure (among other parameters) can be monitored on the OpenFlash Tablet by selecting Diagnostic->My BMW->Realtime Data Display. Once coolant temperature exceeds 170F, boost pressure will be 16-18psi @ 4300rpm (depending on conditions and OTS map selection). Boost will naturally taper down to 12-14psi by 6500rpm. If you experience any misfire, you will need to troubleshoot the vehicles ignition system hardware (ignition coils and spark plugs). Other than that possibility, your vehicle should perform smoothly and consistently. Lastly, t is very important to run quality premium fuel.
