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) |

Replacing the D-Jet injection with any modern, aftermarket injection system will require replacing some hard parts. You will need new injectors, the impedance on the D-Jet injectors is not correct for modern injection. You will also need to replace the circuit board on the throttle body with a TPS. And you won't be able to use the stock harness, you will need to make your own our buy one ready made.
The CHT and the air temp sender will have to be replaced. The stock sensor for a 3.2 Carrera/964/993 works well in a 914 with modern injection and is a bolt in on a 914/4 head. If you wire it correctly, you can use the stock relays on the relay board for the ECU and fuel pump relays. The rest is just wiring. |
