AEM's Series 2 Programmable Engine Management System is more powerful than its predecessor. In addition to more robust hardware, there are several improvements over the original EMS, noted in the chart below. Like its predecessor, AEM's Series 2 Plug & Play EMS plugs directly into a vehicle's factory ECU harness and requires no additional wiring or hardware. Windows® compatible software (XP,vista, windows7) makes the task of copying, viewing and manipulating data as simple as a click of the mouse. The new AEMTUNER software is infinitely adjustable software and allows tuners to program virtually any combination of engine control, power adders and auxiliary devices, and accurately delivers proper amounts of fuel and correct ignition timing for any boost level or operation condition.
- Plugs directly into the factory harness. No rewiring necessary.
- Uses all the factory sensors.
- Includes start up calibration.
- System is fully enabled and unlocked - never pay for upgrades !
- Context sensitive help eases tuning process
- Maps can be password protected by the tuner to prevent unauthorized usage or sharing.
