AA/HP Tuners Remote ECU Tuning Device for Sea Doo Spark 90hp Base Models or the GTI 90
Looking for the best/most badass ECU tuning available for your Spark? 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.
The Spark has very mild tuning from the factory. This makes them very easy to increase power through an ECU flash. Through data logging capabilities 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 other products and higher HP watercraft files to the Spark. We then slowly pushed the limits of timing with different air/fuel ratios to increase power beyond the 90hpp mark. The biggest gains we feel are in the mid range and how the Switch responds when getting on the throttle... to us, this is night/day difference and acceleration shows it.
In testing, we improved 2-4mph on top end, and greatly improved acceleration.
Price includes HP Tuners RTD, OBDII to Polaris Diagnostic Port cable, necessary credits to flash your ECU, and one AA custom tune (more tunes optional)
AA/HP Tuners RTD device allows you to flash via your smartphone to through your Switch's diagnostic port. This allows you to flash different tunes or go back to stock for dealer/warranty work.
Allows you to log engine parameters and view/erase trouble codes from your phone
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 8500 RPM (stock is 8050).
AA's wicked timing curve is safe for the fuel used, but does a much better job of finding timing limits for ramp up/more torque. Many others simply focus on wide open throttle timing/fueling. The switch timing curve is extremely mild from the factory, and this is where most gains are made.. along with optimizing air/fuels to go along.
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 estimated at 95-100hp
Level 2: 91-93 octane tune estimated at 105-110hp
More products in the works to increase RPM for even more power
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 a Switch 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 on the Spark. If others claim more power/gains for the same mods use caution in believing it!
Please note there is always a very small chance that the tune in your vehicle is not one we currently support. If this would be the case, we'd need your ECU for a very short time, then wait for HP tuners to support the vehicle, so we can then build your files. This is rare, but a situation that could happen. If it does the device is not able to read your OEM/stock file and will let you know to contact us for support.
If you have any other needs in these tunes, or any concerns; please e-mail!
