Apexi Afc Neo Install Into Rs-4s Series 2

I've bought an Apexi AFC Neo off a forum member, and have the manuals from the Apexi website. I also ordered an Apexi ECU Harness from Nengun so I don't cut into the original ECU Harness.

My question is, has anyone on here installed one of these before? If you have, please let me know how it went, what to do etc.

Cheers,

Adam

if you bought the harness then its should plug straight up

you may need to set the afm type tho, should be easy enough to find the info tho

the neo may even just have a menu and you tell it what motor (not sure, just a guess)

i put an old school safc on my r32, it reads the afm voltage then adjusts it up or down a percentage - your best to do this on a dyno but you can probably pull a few % of fuel out up the rpm range

or grab a wideband and get it up the exhaust and tune it yourself

As Tom said, it should plug straight up!

In the settings menu, set the 'Type' as hotwire and engine as 6 cylinder.

Also make sure it is all set at 0 correction before you start your car :huh:

I think the harness he means is like an extension the harness itself get cut and not your ogigional car harness. If I were you and had a series 2 I would sell it save a few hundred more and get a nitune! Much better onption way more tunability.

The advantage of the harness is that you can do the soldering on a bench and then just plug it in. You will need the pinout chart from the DIY section (although there is probably a basic pinout with the instructions). You can play with it yourself but really it needs to be tuned on a dyno or you could damage your engine.

Really you would be better off with a Nistune chip and sell the SAFC to someone with a S1 or M35 (i.e. someone who can't use a nistune chip).

I'm more looking to use the SAFC to get better fuel economy, by leaning out the Air/Fuel ratio for daily driving. And thaat way I can increase it for the track. I did think of the Nistune, but I can't really justify it for what they cost. The AFC Neo I bought cost me $250, the harness was just under $200. I bought the harness as I learnt the hard way about splicing devices into my S13 ECU harness and messing it up.

You have spent $450. Nistune is about $500 including software but for the extra $50 you can set the afrs much more precisely, set timing across the range, get rid of the speed cut etc etc. In either case you need to get a proper tune, preferably on a dyno. I had a SAFC and SITC as well as a wide band meter and played with it myself but couldn't get the same results as a good tuner on a dyno. I got better results with a chipped ecu (sadly not a Nistune as I have a S1 stagea).

      But we haven't even gotten to the point of talking about stateless controllers or any of the good stuff yet!

      You guys need to take this discussion to another thread if you want to continue it, most of the last 2 pages has nothing to do with OP's questions and situation

      And this, is just ONE major issue for closed loop control, particularly using PID. One such issue that is created right here, is integrator wind up. But you know GTSBoy, "it's just a simple PID controller"...

      Nah. For something like boost control I wouldn't start my design with PID. I'd go with something that originates in the fuzzy logic world and use an emergency function or similar concept. PID can and does work, but at its fundamental level it is not suited to quick action. I'd be reasonably sure that the Profecs et al all transitioned to a fuzzy algorithm back in the 90s. Keep in mind also that where and when I have previously talked about using a Profec, I'm usually talking about only doing an open loop system anyway. All this talk of PID and other algorithms only comes into play when you're talking closed loop boost control, and in the context of what the OP needs and wants, we're probably actually in the realm of open loop anyway. Closed loop boost control has always bothered me, because if you sense the process value (ie the boost measurement that you want to control) in the plenum (after the throttle), then boost control to achieve a target is only desirable at WOT. When you are not WOT, you do not want the the boost to be as high as it can be (ie 100% of target). That's why you do not have the throttle at WO. You're attempting to not go as fast as you can. If the process variable is measured upstream of the throttle (ie in an RB26 plenum, or the cold side pipework in others) then yeah, sure, run the boost controller closed loop to hit a target boost there, and then the throttle does what it is supposed to do. Just for utter clarity.... an old Profec B Spec II (or whatever it is called, and I've got one, and I never look at it, so I can't remember!) and similar might have a MAP sensor, and it might show you the actual boost in the plenum (when the MAP sensor is connected to the plenum) but it does not use that value to decide what it is doing to control the boost, except to control the gating effect (where it stops holding the gate closed on the boost ramp). It's not closed loop at all. Once the gate is released, it's just the solenoid flailing away at whatever duty cycle was configured when it was set up. I'm sure that there are many people who do not understand the above points and wonder wtf is going on.

      This has clearly gone off on quite a tangent but the suggestion was "go standalone because you probably aren't going to stop at just exhaust + a mild tune and manual boost controller", not "buy a standalone purely for a boost controller". If the scope does in fact stop creeping at an EBC then sure, buy an EVC7 or Profec or whatever else people like to run and stop there. And I have yet to see any kind of aftermarket boost control that is more complicated than a PID controller with some accounting for edge cases. Control system theory is an incredibly vast field yet somehow we always end up back at some variant of a PID controller, maybe with some work done to linearize things. I have done quite a lot, but I don't care to indulge in those pissing matches, hence posting primary sources. I deal with people quite frequently that scream and shout about how their opinion matters more because they've shipped more x or y, it doesn't change the reality of the data they're trying to disagree with. Arguing that the source material is wrong is an entirely separate point and while my experience obviously doesn't matter here I've rarely seen factory service manuals be incorrect about something. It's not some random poorly documented internal software tool that is constantly being patched to barely work. It's also not that hard to just read the Japanese and double check translations either. Especially in automotive parts most of it is loanwords anyways.
