E6X Fuel & Ignition Computer
The Haltech E6X is a powerful "real-time" programmable fuel injection and ignition system computer designed to control most ignition type engines. Whether 1-6, 8, 10 or 12 cylinders, 1-2 rotors, naturally aspirated, turbocharged or supercharged, the HALTECH E6X can control it.

The E6X System optimises engine performance through the following capabilities:

- Ignition timing control
- Fuel control
- Idle speed control
- Closed loop

The E6X is much more than a programmable fuel injection computer - it provides logging of engine data and allows access in real time to maximise performance and trouble-shoot problems in a vehicle while running.

Typical Applications:

- Control of fuel injection on modified engines
- Conversion from carburetion to fuel injection
- Race and rally applications of all description
- Design and development purposes
- Educational use by universities and technical colleges
- Original equipment in cars and motorcycles.

The patented Haltech system of programming virtually eliminates the input of numbers. You simply manipulate bar graphs by pressing arrows keys on the attached PC running Haltech Programming software. Manipulating the bars allows you to increase or decrease the amount of fuel delivered or ignition advance at that particular RPM and load point. The process is repeated for all load points in each rpm range.
Ignition timing is precisely mapped through the RPM range so that the exact timing required to obtain optimum performance is applied in every RPM and load range.
