Once you login, navigate to the Protocol Database. Once here you can use the drop down menus to discover any vehicles ECU type. This is to aid you in the selection of the tuning method and tooling best suited. You should also take a look at the Wiki to see if there are any known issues regarding tuning of your ECU.
After using the Protocol Database, you should now be aware of the ECU type. To determine the best tool to use, we recommend using websites such as http://flashtec.ch/ and proflash.works. Here you should find extensive amounts of information on each of the various tools including the supported ECU types. You may also wish to visit Ebay and Amazon for price comparisons. PrecisionCodeWorks supports all master flash tool formats (OBD, BDM, Tricore including TPROT). Note we are in the process of building a lookup service for this.
Following the instructions of your tuning tool, download the Original ECU file from the ECU. Make sure you check have checked our Wiki to see if we have any expert notes regarding the ECU.
Navigate to 'Build your Tune' and complete the three steps. The first step is to upload your original ECU file. This is the file we will modify to your desired calibration. You can see a demonstration of steps 6, 7 and 8 in our demonstration video.
Once your file has uploaded, you will be shown the options for your original file. Select your tuning profile (reviewing the various profile data) and any DPF/EGR switches and confirm. If there are any issues, you may raise a support ticket to have an engineer look at your Original ECU file.
Once the system has built your selected tune file after around 30 seconds wait, simply press the download button and the file will save to your computer. Please note that this is not a standard file, it is specific to your original to ensure maximum compatibility.
After flashing of the ECU is complete, the car should be calibrated to your chosen profile. Take the vehicle for a drive and feel the difference for yourself. If you are not happy in any way, please raise a support request and let us know. We pride ourselves on our work.
