IQ3 Street - Adding Haltech GPS
Configuration settings for using a Haltech GPS kit (HT-011310) on a Racepak or Haltech IQ3 Street dash: Wire signal into dash pin 32 Sensor type = "HE RPM Input" Raw data value B will become = 24 Pullup resistor = Off
How to use a temperature sensors on a SPI
When using temperature sensors on AVI inputs, the calibration Haltech provides is correct. This is because the AVI's in the Haltech use a 1k pullup to 5 volts. When using temperature sensors on SPI inputs, the calibration Haltech provides is ...
EGT sensors – everything you need to know (and then some)
What is an EGT? EGT stands for Exhaust Gas Temperature, and to measure it we use EGT sensors. The most common EGT sensor is a K-type thermocouple, but not all K-type thermocouples are used to measure the exhaust gas temperatures. You see we could ...
Narrowband vs Wideband: Oxygen Sensors Explained
Today we’re talking Oxygen Sensors: what they are, how they work and why you need them. The Oxygen sensors can usually be found screwed into the exhaust system. They are located closer to the engine than to the tailpipe. Their job is to measure the ...
Hall Effect or Reluctor?
The two most important sensors on your engine are the crank and cam sensors, so it’s super important to ensure they’re installed, wired and configured correctly. Sensor Type: Hall Effect or Reluctor? A Hall effect sensor typically has 3 wires. Power, ...
Extra Sensory Perception. What Sensors Do I Need ?
One of the questions we get asked quite often is: What sensors are required in order to run an aftermarket ECU? While there are many additional sensors you can fit to further increase the functionality of your ECU, there are some that are essential ...
Wideband O2 Sensors explained
What is an 02 Sensor what does it do? Broadly speaking there are two different types of O2 sensor available, wideband and narrowband. Both sensors have their place in tuning an engine, narrowband sensors are designed to be used in conjunction with a ...
HT-010610 "Cherry" Hall Effect Sensor
Information on the Haltech HT-010610 "Cherry" Hall Effect Sensor The HT010610 is a Hall Effect sensor with a sinking current output. This requires a pullup resistor to generate a signal that can be used by the ECU. It is triggered when an iron tooth ...
Throttle Position Sensor - Finding the Correct Wiring
This guide is to help find the correct wiring of a Throttle Position Sensor (here in referred to as a TPS) when the information is not provided by the manufacturer. What is a TPS? A TPS provides throttle opening angle information the engine ...
Temperature Sensor Problem Diagnosis
What is a Temperature Sensor A temperature sensor is actually a resistor that changes its resistance depending on temperature, typically using something called a thermistor. It is this resistance change that can be used by the ECU to interpret ...
Using ABS Wheel Speed Sensors with Nexus or Elite ECUs
Most factory ABS wheel speed sensors will be a two-wire Hall Effect type. These are powered sensors that produce a square wave pulsed output unlike a non-powered variable reluctance sensor that will produce a sine wave output. Wiring of a two-wire ...
Manifold Absolute Pressure (MAP) Sensor
A Manifold Pressure Sensor, commonly referred to as a MAP Sensor, is used to measure vacuum or boost in the inlet manifold, and is often used as the primary load input to the Elite ECU. A MAP Sensor is a powered sensor that typically has three ...
Flex Fuel Composition/Temperature Sensor
A Flex Fuel Composition/Temperature Sensor is digital sensor used to monitor the ethanol content of the fuel as well as the fuel temperature. This can be used with your Elite ECU for Flex Fuel tuning to suit a varying blend of ethanol in the fuel, ...
