The Weistec S63TU tune provides solid gains through out the entire powerband, This is on a vehicle with stock exhaust and turbos. Additional upgrades will result in even more power.
Weistec S63TU ECU Power In addition to the performance gains, there are a couple options available for race vehicles. First is the "Burble". The M4 GTS comes from the factory with this in a mild form. You can choose "Off" "Mild" or "Aggressive" for the "Burble". Many seem to prefer aggressive, but we gladly will let you choose based on your preference. The other race vehicle option would be Catalyst Heating. On race vehicles, many times the catalysts are removed. In those cases, there is no need for the catalyst heating which would just be making excessive noise on a cold start of the race vehicle. If you have a race vehicle with the catalysts removed, Catalyst Heating can be disabled.
Once you place your order for the tune and the Cypher Handheld, we ship you the handheld complete in a case with all necessary cables and a USB drive. On that USB drive is a PDF instruction manual for the tuning process. The Cypher must first be updated using the link the PDF instruction manual then paired to the vehicle to either read the stock file or identify the software versions on the ECU. After that process, the handheld is connected to a PC so that you can download the ID file and email it to [email protected] so that they can begin the process of making your tune file. Once ready, an encrypted file which contains both the stock file and the tune file, will be sent back to you. You upload the file to the handheld and then use the handheld to flash the car.
