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.

Part of the problem is the cam, so what cam are you using?? Even a Web73 is a pain to tune due to the valve overlap to get a good idle.

Far as I can tell there should be plenty of fuel delivery even for a 2270. I should try a test on DaveHunts 2270 and stick back on the Djet parts and tune just to get a baseline MPS. I have pretty much go my 2056 with a Raby 9550 (web73) set up and it rocks!

Well, Dave ya wanna try????

The problem with Djet tuning is you have 3 thats it , 3 tuning tools, idle, partload and WOT. Its a lot of trial and error to get them set up right using a wideband O2 sensor. You don't need a O2 after you set it up as it is hard wired then.

RichD, did you repair the exhaust leaks yet so we can tune yours.
