Haltech DOS software has been rated highly by many users and is one of the most easy to use programs for aftermarket ECU’s. The use of bar graphs to display information combined with the ability to manipulate the bars without numerical entry, means that the fuel and ignition points can be easily manipulated in real time. This can save valuable tuning time resulting in less time on the dyno. This translates into cost savings for the end user.

The screen shot above shows the Fuel map programming screen for the E6K software. The displayed RPM range is 4500rpm across the full range of load. A series of these load maps construct the 3D fuel map. The engine data is display below in the green section to show current RPM, load, temperatures etc.

Haltech Software supports many correction maps for coolant temperature, air temperature, battery voltage, barometric pressure. Additional maps such as the cranking maps, throttle pump maps and primer maps add to the drivability and general quality of engine running and starting. These features help make a modified engine start and idle as well as most factory OEM ecu’s running factory engines.

Many auxiliary options can be controlled through the PWM and output options programming screens. Options can be programmed and disabled if desired.

NB: These units are application specific, Haltech or its representatives should be contacted for assistance when ordering an extra injector driver box.

The display is divided up into three sections representing lean, stoic and rich. The colours change to indicate which section you are in. Each section has 10 LEDs to provide a useful reading of your O2 sensor.

SIX PACK 12V IGNITION COIL

The six pack has three double coils mounted on the one bracket. For use with 6 cylinder or 12 cylinder wasted spark direct fire applications 

SINGLE 12V COIL WITH IGNTION MODULE

A high energy ignition coil and ignition module mounted on the same bracket. . For use with distributor, or multi-coil sequential fire applications.

The Haltech dual Hall Effect sensor has been in production for a number of years and it has been a popular item due to it’s ability to be able to generate both home and trigger signals from the one sensor.

Very occasionally there have been reports of problems caused by the temperature rating of the main chip in the system so we have reacted by sourcing components with higher temperature ratings. The main chip in Haltech dual Hall Efect sensors (both S1 and S2 variations) now has an improved temperature rating of 125 degrees C commencing with sensors manufactured from mid-August 2000.

The S1 and S2 sensors are used in conjunction with rare earth magnets which must be mounted in non-ferrous surrounds. It is vital to use Haltech supplied rare earth magnets. You may buy cheaper rare earth magnets at your local electronic store but there are many different types of rare earth magnets made from different materials and with greatly differing properties. Some magnets don’t have the required magnetic properties and others will fail at higher temperatures. Others will work correctly at first but will fail over time, particularly at high temperatures. The rare earth magnets supplied by Haltech are carefully chosen for their magnetic and temperature properties to give a long life even if operated at fairly high temperatures. Don’t spoil your installation for the sake of a few extra dollars!

The Ignition module is an amplifier designed to fire an electronic ignition coil. The ECU ignition signal connects to the ignition module, which then fires the ignition coil.

There are two main types of Ignition Modules, they are:
