Unlocking the SVHO w/ RIVA Stock 8000 Reflash: The Watercraft Journal EP. 85 

Sadly, we do it to prove a point. (Well, several actually.)

@@watercraftjournal What point is that

We walk the walk.

Noted!

Awesome! We're happy we could help!

Love the new 2021 GP1800R I got mine added a riva tune riva intake and ride plate my digital gauge shows 81MPH it’s probably going 78-79MPH

Thankfully the crack is located in a specific spot, and Yamaha has addressed it with the 2021 models.

@@watercraftjournal nice to hear this. But cracking happened from cooling engine to fast? Some ppl idle to cool it before turning it off, idk if thats true or not

Glad you enjoyed it!

Yes, RIVA is a major advertiser for The Watercraft Journal. So we use, test and endorse most RIVA products.

The MaptunerX tune is the exact equivalent of a SCOM for a Sea-Doo.

@@watercraftjournal just way more expensive.

Right on! And thanks for the support.

It's a winner.

You're welcome!

We ticked the GPS at 73.1mph on a 2014 FX SVHO - some we sneaking out with delayed throttle controls.

I did 73 according to the speedo on my 2016 SVHO Cruiser.

LOL! It's not too bad when you make up your mind to ride all year long, regardless of the weather. We tease those guys who claim to "ride 365" but won't go out if its a tiny bit chilly.

@@watercraftjournal Tiny bit I don't mind as I will go out riding if the temperature is only 20C as that can be 20C cooler than the middle of summer ;) but there is no way I would be out on the water if it was anything cooler than 20C :) , where as 20C is probably a nice warm day for you guys :)

It's truly the most impressive before/after experience we've had on the water.

Well , since I HV the exact ski, exact color, everything, I'm gonna look into this. Is this the fastest tune for this ski?? I don't wanna go half way, I want THE fastest tune. Thanks.

Intentionally for the videos

Meh, you'll hear it more than you'll feel it. -K

@@watercraftjournal So it's not worth it on a NA ski

Thanks!

Glad you enjoyed it!

Yamaha's do not require a catch can.

I would contend any boosted engine needs a catch can (possible exception of Civic Type R baffled head) because they all have some blowby...most just recycle the blowby to the sump where it contaminates the oil

Duper!

Nope

Purchase of a Maptuner comes with one tune of your choice.

ARE YOU NOT ENTERTAINED?!

Literally no clue.

No not really. Save your money for a supercharged ski later!

It is 100% reversible.

Watch today’s “Quick Topic” video, you’ll enjoy it.

Not at all.

Does a stage one tune from riva only come with one tune the 8000rpm? And is not detected when going in for service?

@@Matt-xf6pn already answered service question and no can't be detected

Yes, the Stage 1 tune can be identified by the dealership. This is NOT the Stage 1 tune.

Stage 1 Plus with the stock impeller? That's your problem. What's your RPM?

@@watercraftjournal he is seeing 7900 on the stock tach at wide open throttle, how accurate the stock tach is idk, we tried one of those TTO tachs from greenhulk and never got it to work either. We first flashed the “bone stock” tune into the ECU and saw no change in any performance at all then we did the “Stage 1 + tune” I Believe it was called, and only saw about 1.5 mph gain, then the ride plate only gained about .3 to .5 mph gain, ski is stock other than oil breather upgrade.

Forget about MPH. Pay attention to RPM. If you're not seeing over 8K (8,100-8,150 ideally), you've got a problem, and your problem is the impeller. Grab this now: rivaracing.com/i-18698460-solas-yamaha-160mm-concord-13-20-impeller.html

@@watercraftjournal okay I’ll see if he’s willing this sink a couple hundred more bucks in that impeller. How come the GP1800 SVHO see’s such a big improvement with just a re flash and oil breather as compared to the FX SVHO, to our understanding the motor and “drive train” / “driveline” and even the hull are the same between the two skis just the FX is a little longer/heavier. Does the stock impeller just suck that bad on the FX? One other question. Is that factory tach reliable/correct over 8K RPM on the ‘19 FX? We noticed the speedometer is an absolute joke on the ski, it is just relative to the RPM and what speed you “should” be going in its mind for the RPM, and the speedometer max’s out at 70 and it’s not accurate anyway at 70, it shows 70 when you’re doing 67 on GPS. Does the Tach “max” out like this at say 8k or does it read true past 8K so that we can actually notice if it is turning better RPM with the impeller you listed.

Go ahead and look up our videos on the current FX. We explain why.

VX Limited is naturally aspirated. It can run on 87 or 89 (or 91 if you want) without trouble.

No idea. Go ahead and look that up.

Ah, good question! Unfortunately, not much further past 70 and definitely not accurately.

Ok. Thanks for the response.

@@watercraftjournal You know, I just did 75 on my ski last weekend. Exact same ski as yours, same color, year, model, and my speedo read 75!! Bone Stock.. It's running F ing great! 40 hrs on it now. I'm gonna research your stuff and then call you. I'd like to hit 90 or more. Perfect water where I am. Thanks.

GoPro suction cup.

Why not? Your bass boat has a very flat planing hull.

I don’t tow long distances with them on.

Covers = scratches on plastics and paint job.

@@dreknotz1996 paint fades without just don't drive with them on 😜😜

When you buy the MaptunerX you're provided one tune/map, that you can switch back and forth as often as you like.

No, because the stock HO tune is not speed restricted in any way. You'd have to up to a Stage 1 tune. Call RIVA's Maptuner support with further questions.

No, it's a stock tune.

Anything is possible but consider who their primary buyer is first. The vast majority are cruisers who simply want a temporary thrill of squeezing the throttle. This is why so much of the SVHO’s power is delivered via the torque from displacement of the 1.8L instead of the top end horsepower.

You're over 300HP.

Who says there's two sizes?

@@watercraftjournal K&N site

Go to rivaracing.com instead

Certainly! It's the same SVHO engine!

Yes (if you get caught)

@@watercraftjournal if you get caught? And that's my question! What do you mean? I have 2, both seadoo gtx 300 limited 2018 and 2021. I used maptuner X for a "barebones" tune, I know you can reinstall the factory tune, but I'm hearing these ECU's (for all jet-ski makers) have an rpm history it saves and when you take your ski in that's what the dealer looks at for warranty! So even if you reinstall factory tune (maptuner X saves) they still know! Is this true? If so, there is no way to tune a ski without voiding the warranty.....which sucks because these skis are way more fun with a good tune!

Yes. The Maptuner X must have a license for each PWC it tunes.

Does the license come with the Maptuner?

The first license does/can at purchase.

Your anger is misplaced. Be mad at lawyers and the morons they represent who gave us the need for these regulations in the first place.

68mph is plenty fast out of box and above that speed a lot can go wrong. It's best an enthusiast unlocks the extra power willingly, because 75mph + is mind boggling fast and isn't for novices.

It's absolutely worth it if you know how to work on your own stuff. -K

Nah. You can do this at home.

Not with just a SCOM

Yes, but ONLY with the factory ride plate swapped for a RIVA plate.
