    Well guys, I pulled the trigger and got the Maptuner X straight from Riva.

    Kudos to Brian in tech support and Riva's tune team for smoothing out a small hiccup. Turns out a 2016 192 jetboat ECU had never been mapped until now. They got the whole thing done in less than half a day! Can't thank them enough.

    On my way now to Lake Conroe Texas to try both the 8100 RPM bone stock tune, and an 8500 RPM stage 2 afterward. Hopefully the water is calm enough. If not, I'll just wait until tomorrow morning.

    Right now my mods other than the tune are ribbon delete, cold air intake + PCV breather, type 14 intercooler, hi flow jet pump strainer going to a dedicated intercooler cooling line, and cobra jet steering viper venom ak fins and a tank of boosted octane gasoline (96+ octane) courtesy of Lucas oil racing octane booster on top of regular 91....I may have a riva B2 wheel plus blow off valve in the near future

    I think this should be a pretty good indication of what the stock wheel can produce.

    I'll post results as soon as I can.

    I love my Maptuner.
    Even though in my case - w/ the N/A engine - the RIVA programs boost the torque some but primarily just improve the throttle response.

    I would not, however, run even Stage 1 on anything but premium 93 - and from a good station.
    For me the whole idea for buying the Maptuner has been so that I can switch between the reflash and stock, on the go.

    The only octane boosters/retardants that have some credibility are the Torco, which I would use in a pinch (in a situation like - "no Maptuner on hand and stranded in a place with no premium gas" - very unlikely to happen), and Boostane which is supposedly better, as it does not sediment as fast and does not turn the plugs that rusty color. Still, I would not go WOT with non-premium, why play with fire.

    You will probably have to pitch your impeller to get rpm up to see much benefit. But.. No one has done it yet, so we are anxiously awaiting your results.

    Well the lake is too rough, everyone beat me there with their own toys and its basically stirred soup at this point. Not even going to try. Going to go bright and early tomorrow.

    Yeah, the Lucas is just insurance. It uses MMT just like Torco and Boostane, but not nearly the same amount as Torco, and certainly not the same delivery fluid as Boostane. But it is more widely available in a pinch.

    I may indeed need to pitch the impeller, I certainly don't think I'll see 8500 RPM...but supposedly this tune removes the boost limiter and adds some ignition timing, so at the very least we'll see it give everything it has with a wide open throttle blade. The boat will basically be unloaded with just me on it and the 4 yr old. Given that and my other modifications, maybe I'll get lucky...and if not, i think a B2/ET-LB wheel is probably in my near future.

    Before I get to that point I'll need to install my blow off, the FPR and the high flow pump...among other things.

    Sorry about the wait guys. Had a couple of things come up on Saturday and never got the opportunity to go until today.

    I still had a bunch of stuff on board, and a lot of wind, but fairly decent water...not glass, but nothing more than a foot of chop.

    These are the results of my 8100 RPM BONE STOCK tune: RPM read 8000 on my stock tach. Gps Mph was 49 mph.

    Don't read too much into my speed though. I still had most of my stuff in the boat, and water wasn't bad but certainly not ideal. There is also my CJS viper venom steering plate/fins to consider.

    This tune is nothing more than an RPM raise and boost limit removal.

    After lunch I'll try the STAGE 2 8500 RPM tune which will have more aggressive tune parameters...but I'll have two more people on board so we will see what happens.

    8000 rpm should be 52 mph with a light load. It looks promising. Perfect water slows me down. Best speeds have been in 6-8 inch chop.

    Yeah I figured I was losing a few mph with my current state of things at anything above 25 mph.

    I tried the stage 2 and the boat didn't even crank. I re-installed the 8100 rpm bone stock and it runs fine. It hits 8100 with no problems and 50-51 mph on gps.

    I'll reach out to Riva about the stage 2 tune. I'm sure they can handle it with no problems.

    Well, I tried to load the 8500 tune after lunch, but it would not even crank. Thinking I was stranded at a marina that was 20 miles away by car from my trailer, I reloaded the 8100 and it worked.

    In fact, the 8100 rpm tune is pretty great. We were running it right at 8100 and 50-51 by gps all afternoon before we got off the water. No problems at all with getting to 8100 on the stock impeller and SC wheel. I have no doubts that my boat with a stock pump discharge could hit 53-54.

    In hindsight I figure maybe I forgot to turn the battery back on. After I got off the water today, I was waiting for a good long while for my ride, so I reloaded stage 2 for S's & G's. Fired right up of course!

    I shut it down immediately thinking "Next time!"

    Unfortunately, "next time" will be 3 weeks from this coming Friday due to my work schedule. 3 weeks on and off. 5 years into this schedule, and I still try to jam as much into that last 3 days as I can.

    I feel your pain. I work 2 weeks on and 2 weeks off. A lot of time off, but never enough.

    Good results for just removing boost and rpm limit.

    I wonder if there is enough left in the stock wheel to go further. I guess I'll find out in June. Hopefully with a little bit of added timing from the stage 2 tune, I might see 8200-8300 RPM.

    I realized last night hat I never outlined how to do this install, which is very simple. Riva has a very good install video on YouTube, just search "riva yamaha maptuner x". They lay out everything rather neatly, but I'll list the items required.

    Items required:

    1. Windows (7, 8, 10) laptop computer with an open USB port and online access. Sorry, the software is not compatible with Mac OS, but if you can run a Windows Virtual Machine it should work.
    2. Two of the three cables included with the bundle. The usb adapter, and the ecu/battery harness.

    Be prepared for this process to take a little time. If you have your boat, computer and internet in one location you can probably knock it out in an hour.

    When you get to the point of loading custom tunes from the internet to your maptuner x, pick one of the options and wait for them to update your account. If you immediately try to load multiple tunes, it will ask for an additional tuning license, which you do not want to fork out $600 for. Give it a few minutes, then select another tune. A notice should pop up saying additional tunes are available free of charge. When you have selected each of the tunes you wish to retain on your tuner, execute the synchronize function.

    I downloaded stock file, the 8100 bone stock, and the stage 2 8500. I'm not sure how many tunes it can hold, but it's at least 4.

    Figure 10 minutes to load the tune to the ecu. Make sure your battery is fully charged prior to starting the tune download. If power were to fail during the process, it might brick your ecu. Follow Riva's instructions for connecting the battery and the module precisely.

    Once the tune is done, plug everything back in securely.

    Crank the engine to ensure it starts.

    If you have multiple tunes you want to switch between, you simply load the new tune to the ECU.

    So far this has been a great mod, right up there with the intercooler upgrade and totally worth the money and time I invested...and I haven't even tried the 8500 tune yet. Hole shot is ridiculously improved, and getting up on plane is nearly instantaneous.

    It'd be interesting info if you could compare the tunes on the same day...stock vs 8100 vs 8500.

    The only thing we compare on this forum is top end speed because it's hard to measure the "feel" of acceleration. Unlike in the car world of dyno's and drag strips etc.

    Other things I'd be curious to know is any fuel mileage improvements at cruise. I imagine the factory tune to be fairly rich but it's only an assumption.

    How much do you have invested so far in the tuner setup?

    I'll make it a point to do exactly that, @Jetswu87.

    I can tell you for sure that the boat's hole shot is remarkably improved and I could further improve it with a Lucky 13 cone. I'm sure @SamCF and @swatski can attest that even when using the stock impeller, the 500+ RPM that a modified ECU allows is a total game changer. The boat is simply able to get on plane so much faster and ride higher out of the water.

    As far as fuel mileage, I have only tested the 8100 RPM bone stock tune so far which makes no changes to the fuel mapping or ignition mapping. I have verified that no changes in fuel mileage have occurred with this tune on top of what my other mods were already making which is a slight bump over stock values despite my added steering fins. I believe that once I test the stage 2 8500RPM tune, I will see some level of fuel mileage improvement due to the changes in partial load AFR and ignition timing. Also, without the fins my fuel consumption might be slightly better at some speeds, but perhaps not. If I were to copy the nozzle setup that @SamCF has implemented I will know for sure. I will say that regardless of whether there is a speed loss associated with the fins or variable nozzle trim, the comfort of your ride is in a different league when you can bring the bow down and cut through the water. I'm sure others can attest this as well, and I believe the sacrifice to be well worth it.

    I believe both @SamCF and @swatski have noted significant improvements in mileage with their respective tunes on other threads, so regardless of NA or SC, I believe there is room for improvement...however much of that may be due to the impeller changes and pump efficiency modifications they both have made but that I have not yet done. Perhaps they'll chime in on this subject as they have both done virtually all the testing for pumps thus far.

    As far as what I have invested, I think roughly $300 for my intercooler and plumbing, $100 for the flow strainer and dedicated thru-hull cooling line, $35 for the ribbon delete, $54 for my intake, $179 for my fins, and a little over $900 for the Maptuner X bundle (tuner, cables and ECU license). So about $1570, call it $1600 including minor odds and ends.

    I also have a $60 blow off valve and pipe-T I haven't installed yet because I still need to tap my intake manifold for the vacuum fitting. I haven't done that yet because I would have to take the manifold off to properly clear the cuttings after drilling and tapping. It's a major PITA that I've already done for the ribbon delete, but I'll have to do it again if I want to add a larger wheel.

    I have played with 3 different impellers, each in varying pitches. Regardless of impeller OD or brand/style, the best hole shot comes with higher rpm, period. The factory impeller launching the boat at 8500 rpm is very exciting. The 160mm I'm running now works very well, but it bogs the motor with the current pitch. Everything about the pump matters (sealing, smoothing rough transition, pump cone), but number one is getting the rpm up just under the rev limit.

    Fuel economy is affected by the tune, but every tune will be different. 6000 rpm seems to be the best cruise mpg, so it's all about having your pump and ride plate set up to have the boat riding in an economical attitude at the same time the engine is hitting it's peak economy rpm.

    Previously I used the ride plate to adjust the attitude of the boat for the best compromise between top speed, ride quality and hole shot. With the adjustable trim, I can set the ride plate for best top speed/mpg and trim down for ride quality when needed.

    Well, it looks like I'll be working an extra week. Not getting home until the 14th. Hopefully I'll have the results from Stage 2 fairly soon after that. Sorry to keep people waiting.

    More mod money. If I work extra there's a pile of packages in the garage when I get home. What do you do for a living @Midnight2V? Sounds like an oilfield job.

    Assuming the stock wheel can't get me any further than I already am, I am looking real hard at a rival fuel pump, FPR, and B2 wheel.

    I never could figure out which regulator would work on our boats. It looks like they mount on top of the tank, and I'm not sure there is enough room. Dean's team sells a drop in regulator for $100 that raises fuel pressure by 10 psi. I bet there's a tune for the maptuner that uses that regulator.
