S-AFC II on R33 RB25det tune

[rev210]

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.

Hey what's the diff between S-AFC I and S-AFC II?

new casing? extra feature?

[rev210]

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.

The increase in tuning resolution is much better, but the knock sensor and datalog also make it worth while.

Where did you get yours from, TakaKaira?

What did it cost?

See'ya:burnout:

[rev210]

yep taka's. They take no time to get it to you. mine was like three days max!

from memory it was about $550 after conversion to AUS.

You can't really use my SAFC settings on your car as like you said everyone has diff mods, and my stock A/F ratio could be higher or lower than yours. For $100 you can get it done properly on a Dyno.

Did that include shipping? If not, do you mind telling me what it cost in total?

Thanks

Zahos

[rev210]

Probably $80 in freight

[Zahos]

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

[rev210]

go to takakaira.com

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.

[Zahos]

no worries,

thanks anyhow

wow...version II has fill in the gaps for point to point...awesome...

also data logging and knock sensor is AWESOME!

What size is the case? is it still bigger than a DIN?

[GTS-t VSPEC]

rev210,

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

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!).

[predator]

I could give you mine but its running like shit so probably not a great idea

[DJ_L3ThAL]

**** 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!!!

[Clint32]

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.

[whatsisname]

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.
