EMS 6860 Engine Management System EFI ECU Motorsport

Motorsport Series The Motorsport Series comprises of 3 state of the art Engine Management Computers. The 4860, 6860 and 8860. These ECUs are based on the proven performance of the 8860. Like all EMS products these are fully upgradeable as new software features are released.

Advanced Design

One ECU fits all.  There is no need to send your ECU back for re-programming when you want to fit it to a different engine. The same ECU can be re-programmed by the user to suit almost any engine.

Faster

Analyses and recalculates every engine parameter over 600 times per second. Combined with EMSs advanced programming techniques it will ensure that your engine consistently receives the  amount of fuel and ignition timing that you programmed. This equates to longer engine life and more power.

Better

EMS has lead the way in user-friendly ECU management software and the Motorsport software is again leading the way. Our Windows software is developed by professional software developers who have experience in engine tuning and advanced Windows programming. This becomes evident when you tune any of our systems. 

Key Features

8 User Definable outputs. 4 outputs can be programmed as digital or PWM and the other 4 as digital only. These can be used for controlling thermo fans, Idle controls, variable cams, fuel pumps, Boost Control, Variable water spray, etc.

4, 6 or 8 Sequential Injector outputs with 4 to 1 peak and hold current control

4, 6, or 8 Sequential Ignition outputs (Coil-on-Plug)

7 Dedicated Analog inputs Water Temp, Air Temp, Lambda 1, Lambda 2, Throttle position, Manifold pressure and Battery volts.

8 User Definable Analog inputs for normal temp sensors, Pyro/exhaust temp sensors, Suspension measuring sensors, G sensors, air flow meters, etc.

Stepper motor control. All Motorsport series ECUs hav a dedicated 4 wire stepper motor controller which can be used to control 4 and 6 wire stepper motors. 

Adjustable RPM and load points. The Motorsport series offers 96 RPM points with a 1 RPM resolution and 32 load points with a 0.1 percent resolution. This provides a tuning grid of 3072 points. Of course you don't have to use this many. You can define any number of RPM and Load positions you require to tune with. This provides non compromised tuning ability. The advanced micro code will perform a 3 dimensional interpolation between all load points.

Multiple Load Sensors. All ECUs in the Motorsport Series can be programmed to use 2 load sensors in cases where the engine may have 2 load measuring sensors such as 2 air-flow meters.

Connects to most sensors. This means that you can use your existing sensors with the Motorsport Series.

Advanced trigger circuitry. Automatically filters trigger inputs for noise ensuring that the trigger signal is always 100% accurate. This combined with the advanced auto signal tracking and true zero crossing detection with magnetic sensors always provides accurate timing at all engine speeds.

Advanced Micro Code EMS have put great effort in programming their micro code to ensure it stays in exact synchronization with the engine. This minimizes the risk of misfired and lean strokes therefore increasing engine life and providing more power. The system also performs a 3 dimensional interpolation between load points to ensure that your engine is getting what you tuned it to receive.

***
The Motorsport series now has an advanced engine protection system. 

The ECU can monitor up to 16 input channels and shut down the engine if any channel exceeds the programmed threshold value. Eight of the input channels are analog voltage inputs that can be calibrated to accept any 0 to 5 volt sensor.  This allows you to monitor inputs such as, exhaust temperature, fuel pressure, oil pressure and shut down the engine if any of the programmable  threshold values have been exceeded.

The software for the digital inputs has been expanded to include an extra 4 to

make a total of 5 inputs, for these inputs, new software has been developed to

include gear shift ignition cut & air conditioning control.

A new multi-tooth trigger mode has been introduced allowing you to define which tooth after the sync is the index tooth, this can be used on applications like the Honda NSX & many others.

New trigger modes have been developed that support 4 cyl. Lotus Elise engines.
