UPDATE!!

I went to the Jaycar website to buy one of the DFA kits (Digital Fuel Adjuster, Jaycar catalog# KC5385) And cant find them anywhere; I have a feeling they have been discontinued..

However after a little more searching I found a similar kit

http://www.jaycar.co.nz/productView.asp?ID=KC5490&form=CAT2&SUBCATID=965#11

Which im pretty sure is the kit which supersedes the classic DFA kit which we all know and love...

It says in the blurb that it can adjust air/fuel ratios by adjusting the voltage so yeah.. pretty sure it will do the exact same job..

Peace

I've been using these for a while now & they do a great job. The downside with the voltage adjuster over the DFA is there are more load points to set & so it will take a bit longer to configure. The upside is with more load points you can do finer adjustments.

Looks like they have put the price up on the kits tho.

Edit: there are some ambiguous instructions when it comes to the calibration. It is possible to set these so that each unit (added or subtracted on the hand controller) will equal whatever you want, ie a coarse or fine adjustment. If you follow the instructions to a "T", you could find that the adjustment is so fine so as to make no difference at all. Mine is set for 2 hundredths of a volt (0.02V) per increment, which gives me great control.

If anyone builds one & has trouble working out the calibration, just ask.

Cheers, Leon.

I actually bought a prebuilt kit from eBay (after my initial kit I built didn't work a few years ago :P ) - have a look here. I *think* all the kits are the same but just check with them first - it works with my R33 GTS-T. It is definitely a Jaycar DFA - I have opened it and checked it out :)

Unfortunately, you have to buy it with the hand controller, but after contacting the seller they were willing to drop the price a bit for me. They also responded quickly to my questions so overall pretty happy.

As you will see, the hand controller is a different shape to the Jaycar one but I can confirm that it does work with both the DFA and IEBC.

Anyone here in Canberra could install the DFA and IBC and do a basic setting of the load points?    I bought both pre-built kits from this forum 10 years ago, and its been sitting in my cupboard ever since!   Happy to reward accordingly...

They are relatively easy to install and tune - so long as you have the hand controller to go with them but if you have a S2 with the Neo engine I would really recommend getting a Nistune chip.

Many of the C34 owners from 10 years ago have left the forum but hopefully someone will still have the instructions!

Actually I still have a few files on my computer so I will attach them...

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.
