8860 Sequential Motorsport

EMS have designed their engine management systems to be universally adaptable for most types of engines from single cylinder up to 16 cylinders.

Their systems can control throttle body, multi-point or staged injection, distributor or direct ignition, naturally aspirated or turbo & supercharged engines.

EMS Engine Management Systems are used world wide in all types of vehicles for many reasons: Conversion from carburetion to fuel injection Modified engines Race and rally Off-road buggies Modified Skidoos Racing Boats.The 8860 offers state of the art in Engine Management Computers. Years of research and development by EMS has resulted in this system. It is the first of a new breed of engine management computers by EMS. Like all EMS products this is fully upgradeable as new software features are released. When you invest in this product you invest in the future.

We Believe this ECU is the most advanced system in its price range.

Key Benefits

Faster: The 8860 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 8860 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.

Stepper motor control 

Adjustable RPM and load points
The 8860 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
The 8860 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 8860.

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.
