Sea Doo 300HP Watercraft AA Custom ECU Tunes for HP Tuners RTD

These tunes are for customers that already have the HP Tuners Remote ECU Tuning Device (Or MVPI2/MVPI3) for Sea Doo 300HP Base Watercraft Models Looking for the best/most badass ECU tuning available for your Sea Doo? AA's performance tunes are readily available to gain horsepower and torque. Through our advanced ECU tuning we are able to modify parameters correctly to gain you the power needed. We are highly experienced in tuning these ECU types and this will show. We go for the most horsepower allowable on that fuel, but also make sure mid range power is greatly increased.... all wrapped into a tested tune that is safe to run all day. These 300HP watercraft models has very mild tuning from the factory. Through data logging and many trial tunes, we were able to come up with the best recipe for great power. As we have tuned BRP products for years, we could easily compare our calibrations from various other BRP products to start calibrations. We then slowly pushed the limits of timing with different air/fuel ratios to increase power. The mid-range grunt these gain with tuning is the biggest gain, and this helps them get to top speed much quicker and usually gains 1-3 MPH top speed. Many others claim +30 HP with their 91-93 octane tunes, but we know from experience this is not the case and quite simply not possible without increasing boost pressure. While we believe our mid-range power may be 20+ HP gains, the peak power is shown in RPM increases, and we estimate it to be roughly 320-325 HP output peak. Knocks .22 seconds off in 16 less feet when testing 5-60 MPH with just the tune! Removes OEM speed limitations built into the ECU calibration normally giving you another 2-3 MPH with only the tune. This greatly varies depending on conditions, vehicle/rider weight, and other factors. We also offer a nozzle and impeller for your jet pump which greatly compliments the tune. These vehicles will make more boost/power at a higher RPM due to spinning the supercharger faster. Pick up our AA Machined Nozzle for an extra 50-100 RPM. Pick up our AA 13/18 Impeller for another 100-200 RPM and all around acceleration/speed gains due to the better pitch. With the AA impeller and nose cone we normally see an extra 200-300 RPM over stock. This combination will increase horsepower output to 330-340 due to the 2-3 PSI extra boost at that RPM. The same tune will run excellent at the higher RPM. This results in extremely noticeable faster acceleration over just the tune, and normally another 2-5 MPH. Acceleration graphs were done using the Dragy device and phone application. For 100% Stock and our L1 91 Octane Tune tests, wind was calm at 2-3 MPH and tests were all done without any added waves from other boats, and on the same course within reason. For our L1 91 Octane Tune w/Machined Nozzle and L1 91 Octane Tune w/Machined Nozzle & Impeller tests, ambient temps were 13-15 degrees hotter, wind was mild at 5-10 MPH with the lake being choppy from added waves from other boats and increased wind - still impressive gains seen! Tests were all started from idle speed (4 MPH) straight to wide open throttle. Test were done as consistently as possible with the same 225lb adult driver (winter bulk started early). Price includes one AA custom tune (more tunes optional) Credits may be needed for your device to flash another vehicle if your device is not already paired to the vehicle you are trying to tune. If your device was purchased elsewhere, you'll need to get those from HP tuners directly, or if your device was originally purchased through AA, you can purchase credits HERE Great peak horsepower gains with big mid-range power gains Much quicker throttle response and power delivery giving a whole new feel to the vehicle Throttle by wire limiters disabled Rev limit at a safe 8600 RPM (stock is 8050). AA's wicked timing curve is safe for the fuel used, but we do a much better job of finding timing limits for ramp up/more torque. Many others simply focus on wide open throttle timing/fueling. The timing curve is extremely mild from the factory, and this is where most our huge gains are made and felt. Engine safety: Our tunes utilize and properly reconfigure the knock adaption system in the stock ECU. This system is very well designed to sense engine knock and retard ignition timing well before any motor issues would arise. This means you have motor safety built in that is extremely well done, and works fantastic. AA's modified fuel curve will still get decent mileage cruising but a little less than factory. Our fueling is corrected over the factory lean AFR when needed and richer in key areas. Level 1: 87-89 octane tune with an estimated 295-300 HP and still has big mid-range gains. Though the factory calls for 91 or greater octane, we decided to create an 87 octane tune for those who only have access to 87 octane, or for those wanting to run long distances on cheaper fuel. Level 2: 91-93 octane with an estimated 320-325 HP and huge mid-range gains and up to 330-350 HP with higher RPM via jet pump modifications Why AA tunes over others? �We have been tuning powersports vehicles for a long time and know how to properly test through data logging and reviews/changes. Really it comes down to us having/riding our own RXT-X and wanting to get everything out of it ourselves.... we truly push for the max and are constantly trying to get more out of it. We left nothing on the table. If others claim more power/gains for the same mods use caution in believing it! If you have any other needs in these tunes, or any concerns; please e-mail!
