January 11, 2024

FuelTech’s FTManager software version 5.2 is now available for the PowerFT line of ECUs (also referred to as VCUs or vehicle control units). The update is available for the full PowerFT line including the FT450, FT550, FT550LITE, and FT600. As always, FTManager software and updates are free to download from our website. FTManager V 5.2 highlights include external TCU control (transmission control unit) as well as the ability to replace the OEM ECU in Can-Am UTVs and Sea-Doo PWCs with the FT550 or FT600. Additional features include Electronic Blowoff Control, Water Methanol Injection (WMI), and expanded blip, heel and toe activation methods. A full list of v 5.2 features, changes to existing features, and software/functionality corrections is included at the end of the article.

External TCU Control
The v 5.2 software update provides FuelTech’s PowerFT line of ECUs with OEM CAN communication with the TCU, allowing DSG transmissions to continue running the internal TCU. This feature requires the OEM TCU to be reprogrammed, which is not included in the FTManager software. TCU reprogramming should only be performed by qualified technicians at specialized shops. FuelTech’s research and development teams used VW/Audi DSG transmissions, including models DQ250 and DQ500, to develop and test the software. Compatibility may be limited by the TCU model/version and is not guaranteed, especially for cars on the MQB platform (late 2012 and later).

FT550 and FT600 to Replace OEM ECU in Can-Am Maverick X3 UTV and Sea-Doo 325 RXPX and RXTX 2024 PWC

The updated FTManager software allows the OEM ECU on the Can-Am Maverick X3 UTV to be replaced with either the FT550 or FT600 aftermarket ECU. The v 5.2 update provides CAN communication capabilities with both the dashboard and the electric steering assist and includes protocols for 2016-2020 models and 2021-2024 models. The available FT600 plug and play harness adapter makes upgrading your Can-Am Maverick X3 to a FuelTech ECU easier than ever!

The FTManager version 5.2 update also allows the Sea-Doo 325’s OEM ECU to be fully replaced with the FT550 or FT600. The update provides OEM CAN communication with the dashboard and Sea-Doo’s intelligent brake and reverse (iBR) system. The FT550 and FT600 are IP67 rated against water and fine dust particle intrusion, perfect for taking on tough trails or heading for open water. To make upgrading to the FT550 easier, the FT550 2024 Sea-Doo 325 PWC PNP Harness provides plug and play installation by utilizing the OEM wiring harness.
