User-Friendliness:

The EFIgnition can be configured using the most versatile and user-friendly ECU calibration software ever developed: Tunerstudio. The effectiveness of an engine management system relies not only on the electronics but also on the usability of the software. A clear layout and easily accessible functions are crucial for optimal engine tuning.

In the 3D tuning menu, characteristic fields can be set quickly and clearly.

Through a module in Tunerstudio (VE Analyze Live), the ECU can automatically adjust itself, which has proven to be highly effective.

Data logs can be created and later analyzed with powerful tools for further optimization of the tuning.

Robustness:

The electronics are fully vibration-resistant within this casing, allowing for installation in the engine compartment of off-road vehicles. Additionally, components have been selected for their high temperature resistance.

- 100% waterproof
- 100% vibration-resistant
- Impact-resistant
- Compact design

Vehicles must perform under the most extreme conditions, such as:

• Very high and very low temperatures
• High humidity
• Splashing water or submersion in wading vehicles
• Dust and dirt
• Salt in coastal areas and brine in winter
• High frequencies of vibrations
• Impacts during off-road use

A common cause of failure in engine management systems is moisture ingress. Therefore, the casing of the EFIgnition has been designed to prevent moisture from reaching the electronics.

Through intelligent placement of components, a quad-layer PCB design, and a unique custom housing, the EFIgnition 88 stands as the most comprehensive and compact engine management system globally, measuring 190 mm x 82 mm x 28 mm, excluding the connector.

Connector:

A modern automotive-grade connector with a double seal has been selected to prevent water infiltration. This connector is compact, has proven to be highly reliable, and is also utilized by OEMs in production vehicles.

PCB Design:

• Ground plane ensures interference-free operation and sharp registration of sensor values by the processor.
• Central ground point with multiple ground connections for interference-free operation.
• Rounded circuit traces ensure correct signal transport without loss or crosstalk.
• Components that switch high currents are placed as close to the connector as possible.
• Integrated PCB heat sinks with perforations for cooling components that carry high currents.
• Low-loss power FETs for high-power output stages minimize internal heat.
• Circuit traces carrying high currents are thick, wide, and short.
• Quad-layer PCB design for a more compact build.
• Wide range supply voltage input.
• Switched 5V power supply. Short-circuit proof. Protected against incorrect connections. Very low power consumption.
• Logical placement of inputs and outputs on the ECU connector.
• Bluetooth/WiFi communication module safely shielded from sensitive areas on the PCB.
• Current-protected stepper motor driver.
• Equipped with the highest quality components with high resistance to extreme temperatures.
• All circuit traces have been manually optimized.

Our engineers have refined the design until complete satisfaction was achieved. Subsequently, we dedicated hundreds of hours to testing the ECU, covering tens of thousands of test kilometers in the most remote locations across Europe. Based on these tests, we further adjusted the design. The final result is a reliable engine management system, rich in innovations and manufactured with the highest quality components proven in practice.
