Videos: RIVA & Precision EFI Develop Tunable ECU for 2024 Sea-Doo 325


It was only a matter of time before RIVA Racing cracked the code on not only reflashing the ECU of the new 325-horsepower Sea-Doos, but have it ready to be reprogrammed using a Maptuner. Amazingly, that day is today and RIVA Racing is excited to announce that this new Unlocked MG1 ECU is the ECU that the new Sea-Doo should’ve come with from the factory.

The product of the pairing of RIVA Racing and Precision EFI, the new Unlocked MG1 ECU ($1894.95) is fully tunable using RIVA’s Maptuner tuning devices – meaning, no more sending off your factory ECU to be cracked open, monkeyed with, soldered back together and shipped back. Heck, it even comes with its own tuning license.

So now you can plug the MG1 in, plug in your Maptuner Nano and access the entirety of RIVA’s massive tuning library just like any 300 ACE engine. These ECU’s are ready to ship out May 24th so get your orders in right now if you want to get yours as quickly as possible. [And for those certain to ask yes, this will void your factory warranty. It’s for competition use only. –Ed.]
