NSX, 2017-22

Mega power increases are now available from ScienceofSpeed for your NSX race car!

For more information, click here:

KTuner V2 Touch
Programming device to reflash the factory ECU. Allows wheel horsepower increases from 40 to more than 200 horsepower!

Pure900 Twin Turbocharger Upgrade from ScienceofSpeed
Huge power and torque increases made possible by replacing the the factory turbochargers.

ScienceofSpeed Ethanol Monitoring Kit
Take advantage of the performance advantages of ethanol FlexFuel by using the Ethanol Monitoring Kit from ScienceofSpeed. This allows you to pre-mix

How much power does the KTuner Flash V2 produce?
More than 40-60 horsepower depending on fuel used (91-93 octane) with the stage 1 map. For more details, see the product page for dyno results.

Are other components required?
Downpipes are recommended and increase power output by 15-20 horsepower.

How long does the flash process work?
Once setup, maps can be flashed to the ECU in 3-5 minutes.

Does the KTuner Flash V2 need to stay connected to my vehicle?
No. The unit only needs to be connected during flashing, gauge viewing, or datalogging. Once the ECU is flashed, it can be disconnected.

Is the JB4 Tuning Box compatible with the KTuner Flash?
No. The JB4 should be disabled or removed. See instructions included with the KTuner Flash for details.

For a limited time, NSX Type S Exclusive Paint Matched Manifold Cover Red Charge Tubes are Available Now!

This month marks 3 years since we began working with the Second Generation NSX. "Caliente", this 2020 NSX Thermal Orange project, embodies everything we have learned (and love) about this very special supercar.

100 BHP gain over factory power, suspension lift system, downpipes & valved exhaust that work with the factory mode control switch while giving the car an aggressive exotic exhaust note it deserves, along with many cosmetic touches from ScienceofSpeed. Thank you to all of our customers for allowing us to be a part of your NSX experience!

Modification List:

• ScienceofSpeed Sport Downpipe Set
• ScienceofSpeed Valve-tronic Sport Exhaust

Recently, a 2018 NSX was delivered to us for installation of the ScienceofSpeed Liquid Injection System. This NSX has an aftermarket exhaust system along with the JB4 Tuning Box from ScienceofSpeed. During baseline testing, we noticed that power was down.

Using the JB4 Mobile app, we were able to log variables like throttle angle and found the factory ECU was closing the electronic throttles by up to 25-30% even at factory boost levels. This was very strange considering the NSX was being operated essentially

ScienceofSpeed adds Liquid Injection to Second Gen NSX: As with any turbocharged engine, the performance from the 3.5L twin-turbocharged Second Generation NSX degrades after repeated acceleration cycles. With multiple acceleration runs on our Superflow chassis dyno it's normal to see the intake temperature sensor in the intake manifold increase by 40-50 degrees over ambient temperature.

As the intercoolers and manifold heat up from charge temperature and radiant heat from the engine - we've observed engine performance decrease by 30-40 horsepower after six to eight back-to-back acceleration runs on NSX engines at factory boost levels. Increase boost pressure and increased charge temperatures result in 40-50 horsepower loss in only three acceleration runs.

See what you missed!

Second Gen NSXes attack the track at Palm Beach International Raceway. Fastest NSX of the night was a 2017 NSX at 10.66 @130.8 with ScienceofSpeed Sport Downpipes & new JB4 Tuning Box by ScienceofSpeed.
