Another first from Revo Technik, the ultimate in tunability and control. The ‘select plus’ features variable boost, timing and fuel adjustment. The ‘select plus’ consists of a diagnostic port interface, USB cable and new PC based software. Boost, timing and fuel adjustments can be uploaded directly to the ECU using the software communication mode. The ‘select plus’ not only features the 2 default performance modes like the ‘select’ version, but also includes an additional 3 “user based” modes. These modes allow the user to custom configure their performance settings and upload them to the ‘select plus’. Changes to ECU settings can then be made using just the ‘select plus’. These saved settings can be changed and re-saved using the software as your mechanical upgrades or environmental conditions permit. Combined with the ability to revert to stock programming, and Revo's unique anti-theft mode, the ‘select plus’ is unmatched in its ability to provide the highest levels of control and flexibility, and is ONLY available from Revo Technik.
