EMS Hydra Nemesis 2.7 -- Custom Wire In
KORacing Products » Subaru » Electronics & Tuning

Want a fully capable EMS system for a vehicle that currently doesn't have a Plug and Play option? Building a dedictaed track car? Let us create a custom wired in solution for your engine management needs using the Hydra EMS.

This is the cost of the EMS unit plus a custom adapter to your current harness or cutting the factory ecu out and wiring the hydra connections directly to your OEM harness. It does not include a base map for your particular engine, and does not include tuning. It will include an air temp sensor if one is not already installed on the vehicle.

If you need a complete engine harness as well, that would be available at additional cost. All wiring and harness work must be done on site at KO Racing -- you must bring your car to us for this type of unit and installation.

NOTE: Dual Wideband sensor setups (for V6/V8/V10/V12 engines) does require additional purchase of an external wideband gauge type controller that can output a 0-5V signal to the Hydra.

NOTE: Only Gamma and Epsilon specification units are available as of June 2017.
