Elite 550 – Entry Level
The Elite 550 (HT-150500) is designed for simple four-cylinder applications. It’s a great entry-level ECU for basic turbo or naturally aspirated builds, but it lacks features like cam control and drive-by-wire. If you’re on a budget or just need a simple solution, the 550 gets the job done.
Elite 750 – Versatile Step Up
The Elite 750 (HT-150700) adds support for drive-by-wire and single cam control, making it suitable for more advanced 4- and 6-cylinder builds. It’s a popular choice for turbo setups where you need more flexibility than the 550 provides.
Elite 1500 – Performance Sweet Spot
The Elite 1500 (HT-150900) is often considered the sweet spot in the range. It supports dual cam control, drive-by-wire, and advanced boost control strategies. For turbocharged Barra, RB, and LS engines, the 1500 delivers serious capability without the full price tag of the 2500.
Elite 2500 – The Flagship
The Elite 2500 (HT-151200) is the top of the line. With dual drive-by-wire, advanced VVT control, full motorsport boost strategies, and professional-level logging, it’s built for serious racers. If you’re chasing maximum flexibility for a high-end Barra, LS, or other big-power build, this is the one.
Buyer’s Guide – Which One for Your Engine?
- Barra (XR6 Turbo): Elite 1500 is the go-to choice. Elite 2500 if you want room to expand or add complex features.
- LS V8: Elite 2500 gives you full dual DBW and VVT control. For simpler LS turbo builds, Elite 1500 is enough.
- RB Engines: Elite 1500 handles cam control and boost strategies perfectly. Step up to 2500 if you’re building a big-power drag motor.
- 4-cylinder turbos: Elite 550 works for simple setups; Elite 750 if you need DBW or single VVT.
FAQs
Which Elite ECU is best for a Barra / LS / RB build?

Yes. The Elite 1500 supports single drive-by-wire, making it suitable for most modern throttle setups.
Can I upgrade from an Elite 1500 to a 2500 easily?
