If you’re in different performance circles, it’s very likely you’ve heard the word “SCOM” bandied about. The word itself is not a word, but an acronym meaning “Speed Control Override Module” and is used to supersede the restrictive GPS speed control function on all iControl-equipped Sea-Doo models. In stock form, the factory BRP engine control module restricts the vehicle’s sustained top speed. While peak speeds have been recorded as high as 71-plus mph, the factory GPS speed control will immediately throttle down the engine until it reaches an “acceptable” speed.
The RIVA Racing SCOM supplants that programming, delivering significant increases in top speed with stock ECU. That’s right. There’s no retuning or modifying the factory ECU. Designed to be as easy to install as possible, the module allows system to start in “Sport Mode” for maximum performance as well (bonus!) with “Touring Mode” available by manually selected after start up. Compatible with all 2016 300hp and 260hp models, the RIVA Racing SCOM delivers “up to 75mph top speed on 2016 RXP-X & RXT-X 300 models” according to RIVA Racing, and retains all original dash functions. RIVA also cautions that the “stock ECU limits peak RPM for first 5 hours of operation. Top speed increases should be measured after 5 hour break in period,” so make sure your ski is properly broken in.
As a final testament to the RIVA SCOM’s claims, a recent review by Ray W. revealed how successful the SCOM truly is, writing: “[I] installed the SCOM on my stock GTX 300 Limited and it ran 74 mph. This was with a full tank of fuel, 215 lb. rider wearing a survival suit, and a full storage container dry box. On my model it wasn’t a simply “plug in” installation, some additional wiring/fuse box modifications were required. This depends on if your ski has a 5 or 6 wire diagnostic plug, and if a bilge pump or depth finder have been installed. All extra needed parts are supplied. I contacted tech support and they told me exactly what I needed to do. Great modification for 6-8 more mph.”
