How to Flash Your ECU with the VR Tuned DimSport Handheld Tuner

These instructions are for OBDII flashing your vehicle with the DimSport Handheld tuner provided by VR Tuned.  We do not make the hardware but will do our best to support it.  Dimsport is based in Italy and some support for their tool may take 24-48 hours if issues arise.  For a more in-depth manual, Click Here.

***Please always have your computer plugged in and a battery charger on your vehicle during the flashing process.***

In the event an error occurs, please send us the LOG FILE.  Follow these steps here.

***Important note after you flash – After you have received your tuned file and loaded to your vehicle, if you have had your vehicle serviced and the firmware updated during this time, whether you are aware or not, DO NOT flash your car again.  Doing this will corrupt the ECU because of the mismatching firmware.  Your vehicle will not start and you may have to have your ECU repaired or replaced.  In the event this happens, we cannot be held responsible and there may be costs involved at your expense.  If the firmware was changed, do a new stock read/ID out and we will provide you with a updated tuned file.

If you have the option to READ, please do this, only if that does not work then do a ID.  If you need support, please email tuning@vividracing.com. We will contact you back as soon as possible to request more information or do a screen share.

Once you read out your car, you will need to send us your file (CLICK HERE UPLOAD YOUR FILE). We will then return your tuned file to this same email address unless otherwise specified.

Note to Porsche Customers: The new Porsche ECU’s which are the SDI6,7,8,9,10 cannot be read out of a car.  So what Dimsport does is they reverse engineer the factory tool to get the stock files.  So when a Dimsport Mygenius is sent out and you connect it to your vehicle, it ID’s the car only.  We then send that ID to Dimsport to see if they have the matching stock file to create a tune from.  Unfortunately they do not have EVERY stock file and none of these hardware companies share if information.  Sometimes a firmware might just need to be upgraded by the dealer.  Other times it is just not available.  In the event an original file is not available, you can return the Dimsport for a full refund.  We have no way of knowing what firmware is on the car until it is ID’d..
