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.

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.
