I have the stage 1+ tune on my 2019 gp1800r Absolutely insane, I thought I would want to go for the stage 2, But I honestly don’t need anymore power than this.. FYI; My stage 1+ is covered under Yamaha warranty, not sure if they changed that with the newer year model or maybe in Australia they have different warranty policy You should head down here to Aus mate!! Not sure if you’ve visited before, you’d be more than welcome to join us on some fun days out!!

[@darrelld8266]

I would be curious to know what the Speedo was saying verses the GPS at 79 mph

[@travisnilsson4928]

I would like to know too. My stock 2016 FZR speedo says I'm doing 77mph even 79mph in absolutely perfect conditions which I think is about 10mph too fast. I have seen the gps module that plugs in but not worth spending the money cause I don't even look at the speedo when in going that fast.

[@TommyS-k8d]

Does this void the warranty?

[@GreenHulkGarage]

As in void the entire skis warranty? No way. No mod voids your entire skis warranty. This will be a good read for you www.greenhulk.net/forum/personal-watercraft-performance-skis/yamaha-pwc-performance/yamaha-pwc-performance-4-stroke/262395-

[@zachmencke]

I watched a previous video when you used the stage 1 tuner and you said it "was warranty friendly". Why did you change to saying that it is not warranty friendly?

[@GreenHulkGarage]

The 8000 rpm tunes cannot be detected by the dealer. If you use a tune with a rev limiter over 8000 rpm then the dealer can tell that the ecu has been tuned.

[@Iminlikesinn]

Where is your shop located?

[@marcfairchild4967]

you need to put a different rideing plat on and different Rev limiter and with a full take of gas will run about 82 too 84 on the water

[@CarbonYote]

It comes with the riva ride plate from the factory

[@marcfairchild4967]

yes I know but it has to get more water to go faster reiva make a different rideing plate will help a bunch and get your heads shave will get you more hp as well

[@AlejandroHernandez-ph4hm]

I saw that the stock racing 8800 tune requires a power cooler mod, will it be okay to run the tune on a completely stock jetski?

our tachometer was not installed so I can’t say exactly. It seemed to be around 8200 RPMs

how many RPMs was it pulling on all three runs?

The answer to that is mentioned in this video. Because we are waiting on the arrival for our 2021 RXP-X 300. We will compare the GP and RXP stock for stock, stage 1 to stage 1, stage 2, stage 3. Trust me the content will be worth waiting for 👍

[@darbysnider]

Is the riva stage 1 8300 tune warranty friendly like the 8000 stage 1?

[@GreenHulkGarage]

The dealer cannot tell an ECU has been reflashed as long as the limiter is 8000. But even if you did a 8300 tune, it doesn’t void your entire skis warranty. They cannot “void” your entire skis warranty for doing a mod to your ski. They can “deny coverage” on a failed item if the modification is proven to have caused the failure, but your entire skis warranty is not VOID!! For example, let’s say you reflash your ecu with a performance tune. If your steering breaks, instrument cluster goes bad, a sensor goes bad, etc, then the reflash could not have caused one of those items to fail so they cannot deny coverage. Now, if you have some sort of engine failure then they could absolutely deny coverage on the motor repair. Point i’m trying to make, is your entire skis warranty is not VOID if you mod your ski. Research Magnusson Moss Warranty Act. It protects us consumers when modding our skis 👍

[@Wetlife0069]

Did you have to get the $600 tuning license?

[@GreenHulkGarage]

The tuning license is only $549 in the GreenHulkStore.com, but you also need the MaptunerX and cable to connect the MaptunerX to your ski if you don’t already have them.

[@GreenHulkGarage]

This was the AquaX stock class 8800 rpm tune. The stage 1 is a very safe and reliable tune, but it’s recommended you also do at a minimum the Riva power filter and Solas 13/18 impeller with this tune. If you are only seeing one tune in your tuning library you can contact [e-mail] and he will make the other tunes available to you.

[@deanhansen5041]

I installed a Riva stage 1 tune on my 2017 GP1800. It F'd it up somehow. It's like the air intake butterfly valve won't open up all the way like it's on low RPM mode. And when it is in low RPM mode it's really slow. Uninstalling the tune makes it really really slow and tune uninstalled on low RPM mode it's really really really slow. Nobody at Riva or at my shop can figure it out. Any one else have this issue?

[@GreenHulkGarage]

I don’t think this is tune related at all. Your throttle body is bad. It’s quite common for them to fail and not open all the way.

[@deanhansen5041]

@@GreenHulkGarage Nope, wasted $1472.00 for the new throttle body and 2 1/2 hours shop labor. Now it actually runs worse, dies and the check engine indicator is blinking/beeping. I'm bringing it back to the shop tonight. My ski can't be the only one adversely affected by a tune.
