Yamaha Sidewinder & Nytro HALTECH EFI System DEVELOPMENT

Fuel Trim to Rev Limit, NTK O2 Sensor, Knock Sensing, Full Data Logging, Remote Tuning

July 2024: Moving forward with EFI development for the Yamaha engines and specifically the Sidewinder & Nytro we will be using Haltech.

Haltech is not new to EFI as it was established in 1986 in Sydney Australia. All of Haltech components are designed, built, and tested in their own facility. Although the Haltech systems will be more expensive as an appropriate Haltech ECM alone is almost +$800 over the AEM Infinity 3 we used, NTK Wideband O2 Sensors are available to use along with more advanced ECM/PDM units. The NTK O2 Sensor is much more robust to leaded and exotic race fuels and Haltech’s new series of Nexus ECM/PDM units are vey full featured


The Haltech Nexus R3 combines their typical ECM like the Elite 1500 with a PDM (Power Distribution Module). All of this combined with modern CAN protocol can eliminate a lot of wiring and complexity while monitoring electrical loads. Additional features like WiFi connectivity and an onboard O2 Sensor driver really brings the Nexus to the forefront of modern ECM’s and their capacity.

Dash / Engine Monitoring

July 2024: Haltech makes a very nice line of Dashes for Engine Monitoring but at this time they are not configurable enough for our use in aviation for some of the more unique data we have come accustom to monitoring. They did just release an update that utilizes the new NSP software but I have yet to evaluate it and initial online reports are saying its still not as customizable as the AEM Dashes I’ve been using. Therefore for the time being and testing I will continue to use the AEM Dashes. But this may and probably will change as time goes on and the Haltech community demands the flexibility as seen with the AEM units.
