ECUMaster EMU Classic Tuning Package

This package includes a full remote tuning session!


  • The ECU MUST be installed correctly. This is largely in reference to the wiring of the injectors, coil packs, trigger wires, VTC solenoids (if applicable), boost control solenoid, Idle air control valve, Wideband O2 sensor, TPS, and vacuum hoses.
  • The engine MUST also be mechanically ready for normal operation. To put this simply, a 100% stock engine that runs perfectly fine on a stock ECU will likely satisfy this requirement.
  • The engine MUST be fitted with the appropriate parts to accommodate the end users goal. Quality injectors, turbos, cams, fuel return systems, ignition system, etc.
  • If tuning remotely, the vehicle owner is responsible for knowing how to properly use a timing light during the initial phases of ECU setup. If tuning in person, we will time the engine for an additional fee.

If tuning can not be completed due to any of the requirements not being met, additional charges and tuning will take place after adjustments are made to rectify the issue.

Some common examples of things that will require a tuning session to stop: spark plugs not at correct gap, engine oil overdue for a change, O2 sensor not functioning, vacuum hoses incorrectly routed, injectors of poor quality or incorrect size, lack of a proper exhaust, poorly made charge piping, and even incorrectly selected turbos.

- We are excited to announce a new and improved version of our popular EMU engine control unit: the EMU Classic. Our goal at ECUMaster is to provide the best possible products at an affordable price. The new EMU Classic is evidence of our dedication to that goal. We have improved the design of the EMU based on customer feedback and have kept the price at a similar point. The main improvements are as follows: Improved ignition outputs allowing the use of more than one active coil on one output, Separate 5V output regulator for external sensors, Highly protected H-Bridges (stepper outputs), Galvanic separated USB port, Compact CNC machined, black anodized enclosure (147x62x30 mm vs 155x120x45 mm) Both EMU and EMU CLASSIC use the same firmware and software package. EMU Classic is designed to operate the most advanced and complex engines presently available. The EMU CLASSIC controls fueling, ignition and auxiliary systems on 1-12 cylinder engines including those with drive-by-wire throttles (with an additional module) and VVT. Using the latest technologies in the fields of electronics and software, the ECUMaster EMU CLASSIC has the latest features and an attractive price at only $899.

Common applications for the ECUMaster EMU CLASSIC are modified sports car and racing engines, motorcycles, boats, and stationary engines. Check out this video of ECUMaster products in action.
