DJetronic Limitations Options

[Teknon]

It's probably been said before many times. So if there is a thread you can lead me too all well and good. (IMG:style_emoticons/default/confused24.gif)

I am having a 2270 built and was told the DJet FI will not be enough to handle the fuel requirement of this engine. I am not interested in a mechanical carburetor at all. And have no room for that discussion. (IMG:style_emoticons/default/dead horse.gif)

Why can’t the DJet keep up? Can it be tweaked or larger injectors installed? (IMG:style_emoticons/default/WTF.gif)

“Chicken Little” type members need not answer, as I don’t need someone’s emotional opinion. What I would like is a down to earth technical understanding. (IMG:style_emoticons/default/yappin.gif)

I am surprised no one made a daughter board to augment the existing ECU to test oxygen or whatever would be pertinent.


Thanks for your time and experience.

I agree with James with regard to the sizing of the intake setup.

I also agree that the fuel delivery system is not a limitation as far as being able to deliver enough fuel for the 2270 or larger.

But d-jet requires a mild cam to function properly because it is dependent on manifold pressure. An agressive cam disrupts this.

So you would need to use a very mild cam with your 2270. But why are you building a 2270? More power right? So why would you cripple your motor with a mild cam? You wouldn't. Which is why d-jet is a bad choice.

It's like putting a 3.2L six into your car but keeping the stock 165 width tires. Sure, you can do it, but it makes no sense.
