Yamaha Apex HALTECH EFI System DEVELOPMENT
160+ HP, Dyno Proven, Fuel Trim to Rev Limit, NTK O2 Sensor, Knock Sensing, Full Data Logging, Remote Tuning
September, 2024 - Apex Haltech EFI Flight Testing
I have about 5 hours of ground testing and about 20 hours of flight testing on our new Haltech EFI system for the APEX. I should be ready to build these systems for customers SOON.
Haltech Features:
NTK O2 Sensor - More robust to leaded fuels
Long Term Fuel Trim / Learn Table - Customer Adjustable
Nexus S2 ECM
WiFi & Mobile Application
Onboard Data logging, 128Mb - About 2 hours / 60 ch.
Altitude Fuel Compensation Table
WOT Timer - Enrichens lengthy WOT events
HOBBS meter built in
Fuel Flow/Burn in GPH
Available HP
Current Engine Load
Pricing for this system has not yet been finalized as I decide what combination of Haltech components is best for our application. Bottom line is it's not going to be cheap at approximately $4400 with ECM & Harness. Dash (EMS), and other non essential sensors like Fuel Pressure, Oil Pressure, Gear Box Temp, EGT's, etc will be at an additional cost. Will continue to use AEM 5" & 7" Dash's as they are still the most configurable for aviation.

Side Note: I will still continue to support current customers that have our Apex AEM EFI system. It is a great system and is NOT obsolete. Holley (owners of AEM) simply discontinued the complete Infinity line of ECM's as they have solutions in the Holley brand.
July 2024: We are working on a Haltech EFI system for the Apex. We will continue to support the AEM systems we built and I still use AEM in my own plane. Holley purchased AEM some years ago now but went public with it in late 2022 I believe. Subsequently they decided to abandon the AEM Infinity Line of ECM’s. Not because the Infinity was outdated or obsolete but the reasons for this decision varied on the source, but product (chip) sourcing from Covid, continued backlash from EPA, and Holley simply having similar products with the Terminator, HP, and Dominator ECM’s all possibly had a play in the decision.
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.
August 2024: Ground & Flight testing of the Apex Haltech system has begun.
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.
