Fx SVHO MoTeC M1
I recently bought a Fx SVHO. I installed the listed mods below as soon as I bought it and broke it in as per the manual with the mods. Next thing I did was installed M1 which was on my Seadoo 260 RXPX that I sold last year, I bought the Yamaha M1 wire harness from Ivan at PowertecUAE (our local MoTeC dealer in UAE). Regarding the base startup file what I did is basically downloaded Fx Sho 2008 file package from MoTeC website and adjusted the injector values to be able to use ID 1000 and 3 bar map sensor. I changed the overall fuel trim value from +6 to 0 and lambda values were spot on as per the fuel aim table.
My results were amazing I couldn't believe it an average RPM 8450 top speed on hand held GPS 78.6 MPH with full fuel tank, neutral trim level, stock impeller and stock ride plate. I didn't want anymore for now. My lambda was in the range of 0.81-0.82 at full throttle. That's it, I am very happy with the result. Yamaha did a great job with the new SVHO upgrade and MoTeC what can I say its a really powerful ecu.
My Mods are:
-New Fizzle intercooler with dedicated cooling line from pump
-Riva air filter
-Riva sound suppression delete mod
-Riva intake grate
-Deleting intake ribbon
-Replaced 70C thermostat with a 2009 50C thermostat, stock cooling with blocking intercooler line
-Riva valve retainers
-3 bar map sensor
Finally I would like to thank Nils888 for all his support with MoTeC M1 and Jerry for making all parts available.

I think this si only the start.
85mph are not impossible for this ski and your mods.

You should be faster. Got your RPMS up to around 8600

With retainers already in he could easily turn 8800

No tunnel reinforcement? If I knew that was going to crack soon as I started going faster it would be on order before I even pick the ski up
