D-jet to Haltech 550, Gathering information before I start install Options

[JORACER#40]

Nathan on YouTube Barefoot Garage Jax converted his D-jet to modern EFI using Haltech 550 and hoping Nathan or someone who knows him would message me so I could ask Nathan a few questions.
I am very impressed with Haltech they been very informative and prompt but this is not a common conversion for them.
I am using a variety of sensors manufactures most from The Dub Shop that not standard for Haltech but will work as long I know how to implement each into the tune.
Just trying not to make the same mistakes and be back on the road sooner than later.

This has became necessary due to my D-Jet started failing and trying to get new or remanufactured parts is next to or imposable. (IMG:style_emoticons/default/headbang.gif)

I have either purchased or know what components I will be purchasing. Thanks to the Dub Shop, Haltech and Jax Videos. I was hoping to talk to Nathan about the nuances of each custom sensor and how to integrate them into the tune. Also idle control valve was not covered in the Videos.
I chose the Haltech because it will run stock injectors peak and hold. The D-jet was a great system in its day. Since i am using the stock throttle body and injectors the main reasons for using modern EFI is reliability and cleaner emissions due to closed loop and better processing.
