Well I got my New A'pexi S-AFC II yesterday and after only 2hours it was in and running (no thanks to a completely japanese manual).

I was wondering if those guys out there with the Apexi S-afc hooked up to the factory ECU and running a factory turbo would like to share thier S-afc settings with me so I can get mine going a little better.(R33 RB25DET).

Details include the Hi/Lo throttle %

The Rev point and mixture + or - on low throttle.

The Rev point and mixture + or - on High throttle.

I don't mind if you have different mods to me (more or less) I am just getting an idea of the curve people are using to offset the factory one. With the knock sensor feature I will have a good shot at tuning quicker this way.

Cheer's

:P:):D

differences:

12 vs 8 tuning rpm points

200rpm increments and fill resolution Vs 500 rpm

Knock sensor input

Maintains more stable signal voltage

Security lock feature

Stores 2 different settings

Toggle joystick Vs buttons

Smaller case same size screen

More display parrameters

Has 30 sec data log replay mode.

but is that included in the $550 you said previously, or is that extra? (so $630 with freight?)

It's just that I have allocated myself a certain budget for SAFC + tune, and if SAFC-II fits in that budget, I would prefer to go for that...

thanks

And then you can work it out by making a purchase and not finalising it. It's a good idea to do this rather than ask me because the exchange rates change all the time, I might say one thing and then because the rate has dropped you might pay $50 more.

rev210,

Did you manage to datalog any info at the track last night?

See'ya:burnout:

Na,

I kept forgeting, was too excited to start the thing before staging. It records the highest points reached on monitor mode though and I used that for knock ( 0 ) and rev ( 6800rpm ).

Hiya rev210,

How much benefit have you noticed with the S-AFC II installed? I would have thought with your mods that you wouldn't have experienced much gain?

I was thinking of one too but I thought I'd only bother if I went a FMIC. Are your air/fuel ratios that rich with only a full exhaust and 10psi and worth 'correcting'?

If so, then I might look at doing the same after my dump/front pipe (my priority!).

**** man dont drive yer car, there s a break or leak in the tubing to your boost gauge, zero means atmosphere pressure, u can **** yer engine, may explain the knocks too, trace along the boost gauge tubing and find a leak ot a break, barstards for breaking it!!!

I dont think so, the car wouldnt go very well with a major boost leak. Just check near the fire wall there would be a small black box on the drivers side with a few wires and a small black hose, this hose has probably just cracked or fallen off. Happens all the time and is just there for the boost gauge.

Rob,

147rwkw pre S-AFC2 on the Tilbrook dyno with the FMIC, 3" Ext, filter, CAI & stock boost (7psi) sounds about right. A dead stocky makes ~120-130rwkw on Mark's dyno.

160rwkw post S-AFC2 & stock boost also sounds right.

Get some boost into that thing & make the most of your FMIC & other mod's mate! You should be able to pick up a basic bleed valve set-up for bugger all (festo valve is cheap as) or a 2nd hd Turbosmart/TurboXS for much less than $100. Piss easy to install. Set-up takes a few minutes! You can then use your factory gauge(once you've got it running) & your S-AFC knock indications to adjust it to a safe level until you get a decent aftermarket gauge fitted.

You'll be fine running 10psi (12psi for drag runs) even with the S2 turbo. Trust me 7psi to 10-12psi with your mod's is a big jump in power. Just waiting for the taking as is!

It provides stronger acceleration due to improved A/F ratios, I am not sure how much accelleration yet.

Worth correcting.

I don't think the FMIC is a particularly good value for money mod on the stock turbo, I haven't done the FMIC yet (probably won't) and I estimate a 12 second pass on the stock turbo next outing to the drag strip. The FMIC or not should have no bearing on when you buy the AFC.

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
