SST Valve Body / Mechatronic / TCU Assembly - Rebuild Service
As part of the rebuild service, the Mechatronic / Valve Body will include the latest version of the EVO ROM software installed. For the Ralliart owners, this software upgrade will give you the S-Sport driving mode and launch control. You may need to slightly raise your rev limiter via the ECU tune if you plan to go WOT while in S-Sport. The factory limiter on the Ralliart is just under what the transmission will want to shift at while in S-Sport mode.
Let us know if you have any questions or if you would perfer to have the Ralliart ROM software installed.
