What’s the difference between Profiler EFI & the Full Size Profiler?

The larger  has the same Traction Control features, but also has optional Event Timer Outputs, Ignition Controls, Bump Box and ProAxe features. Profiler EFI uses the cars ECU to manage those functions externally, which is a lower investment in a Profiler Level Traction Control System.

So if you’re using Holley EFI, FuelTech, Haltech or other EFI Systems, you can directly integrate the Profiler EFI into those ECUs and gain the full power the Profiler with a much smaller footprint.
