Haltech ECU and Accessories

We get a lot of questions about using a Haltech ECU and what is all needed to use this.  We will dive into this right after this legal disclaimer.

 

IMPORTANT EMISSIONS NOTICE:
In many states, it is unlawful to tamper with your vehicle's emissions equipment. Haltech products are designed and sold for sanctioned off-road/competition non-emissions controlled vehicles only and may never be used on a public road or highway. Using Haltech products for street/road use on public roads or highways is prohibited by law unless a specific regulatory exemption exists (more information can be found on the SEMA Action Network website www.semasan.com/emissions for state by state details in the USA). It is the responsibility of the installer and/or user of this product to ensure compliance with all applicable local and federal laws and regulations. Please check with your local vehicle authority before purchasing, using or installing any Haltech product.

 

Now that you have decided that the above fits your situation, the first thing you need is the ECU.  We have supplied a chart from Haltech that gives a comparison of the different ECUs and their features.  For most people, an Elite 2500 will be sufficient.

 

Once you have decided on your ECU, you will need to decide how you want to wire this in.  There are a few options here  If you want a more plug and play experience, the Boomslang Plug and Play harnesses are probably your best bet.  These will plug into your ECU and your existing stock engine harness.  If you are wanting to do some rewiring, have a bad engine harness, or if your other mods are going to have to cutting into you engine harness all over the place, you may want to consider going with the Universal Wire-In Harness from Haltech.

I highly recommend running 2 widebands on a v engine. The haltech Can system is a lot smarter than just a plan 5 volt input and it will trim both banks independently:Haltech WB2 Dual Channel CAN O2 Wideband Controller Kit – R'venge Performance (rvengeperformance.com)The Haltech has an integrated Map sensor, if you are okay with the 3.5 bar limitation on that you won’t need that.You have your boost controller here:Haltech Boost Control Solenoid 3 Port 1/8th NPT 33Hz – R'venge Performance (rvengeperformance.com)You will also need an air intake temp sensor:Haltech Air Temp Sensor 3/8 NPT 18 TPI (Incl Delphi Plug & Pins) – R'venge Performance (rvengeperformance.com)The aem flex fuel sensor will save you about $60 because it comes with the an adapters:AEM Ethanol Content Flex Fuel Sensor w/ -6AN fittings Kit – R'venge Performance (rvengeperformance.com)Works the same as the Haltech.

For the DBW, you want the smaller throttle body if on a stock plenum, the mitsu pedal and wire and the bosch throttle body connection.
