Fitting and Tuning a Haltech Interceptor
Fitting a Haltech Interceptor
From the outset, the Haltech Interceptor was designed to be simple and quick to fit and tune. To this end, Haltech has adopted an approach where all currently supported vehicle types can be fitted and started by simply wiring the interceptor using a vehicle specific wiring diagram, and then loading the Haltech Interceptor with a vehicle specific default map. The engine can then be started and should run as it had previously, as Haltech default maps apply no corrections. The engine is now ready for tuning.
Haltech provides a "Haltech Interceptor Software Tools" CD that contains the Haltech Interceptor programming software along with default maps for all currently supported vehicles. Additionally, the CD contains a folder with PDF wiring diagrams for all currently supported vehicles. The wiring diagrams can be printed from any computer with Adobe Acrobat Reader installed and access to a printer. The use of the Haltech Interceptor programming software to load the default map is detailed in later sections of the manual.
The complexity of the wiring varies from vehicle to vehicle, but the minimum complexity consists of wiring to the following factory ECU loom wires:
- Splice to +12V Power
- Splice to Signal Ground (low current, low noise)
- Splice to Power Ground (high current)
- Cut engine load signal and connect to each side
- Cut engine position signal and connect to each side Additionally, many vehicles have additional signals that must be connected:
- Cut MAP sensor signal and connect to each side (to defeat over boost fuel cut)
- Cut boost control solenoid signal and connect to each side (to enable boost control)
- Cut road speed signal and connect to each side (to defeat speed limiter)
For most vehicles the Haltech Interceptor can be installed by cutting or splicing just 5-10 wires of the factory ECU loom. An experienced installer should be able to install a Haltech Interceptor and be ready to tune in 30-60 minutes.
