Safc Ii Vs Neo

[tmc_2]

Ok well I'm making the purchase of a SAFC II. Haven't found any cheaper than $380 unfortunately... but such is life.

Who should I go to on the Gold Coast for tune etc..??

And I've been told I can install it and run the car for a while before the tune and won't cause any damage. Is this correct?? (the SAFC II is currently tuned for a Silvia).

Yes u can wire it up, as long as u dont touch and values , make sure there is no previous tune and all values are zero. The only thing u can tune is DEc/AIR that stops it stalling an minimising poping between gear changes, thats all u can tune safley ur self. u can find a DIY in the diy section of this forum.

Any good tuner with a dyno should be able to do it in no more than 2 hours dyno time max.

Thanks to all for the help!

Bought a SAFC2 for $300. Got tuned and dyno'd by Matt Spry on the Coast.

183 rw at 11 psi. I'm quite happy with that with my current setup.

[tmc_2]

Good to hear, nice power figure.

hows the knock readout? i find it handy for a bit of peice of mind.

[Strik3r]

just so you know, the actual figure will be closer to 195+rwkw.. matt's dyno is a tad low I think thats a good thing though, your in for a pleasant surprise when you go up against someone claiming a 190-200rwkw tune on a dyno that reads high.

i have my SAFC2 sitting in a plastic bag in my back seat.. out of curiosity, did you wire it up yourself ? and if so, if i was to bring some drinks along, would you be willing to help me wire mine up ? Matt said he'd do it for $100 which aint expensive, but its $100 that i should be able to save quite easily.

With an SAFC II and a CENTRAL20 ecu i got 207 rwKw at 12psi and approximatly 217 at 14 psi.

[Anakha]

Sorry for the late reply.

Sent ya a pm strik3r.

Havent actually got the knock working yet. I connected to knock 2 wire atm and not working - gonna change over to knock 1 and will repost.

alright guys... i'm set on a air fuel controller (wont be getting a pfc or any ecu).

i have three choices:

- SAFC Neo

- SAFC II

- Gizzmo CamFC

we'll do em in order

SAFC Neo

- like everyone has said, the extra load points arent really such a bonus.

- wanky color screen

- NO knock sensor

- Completely new case design

- Compact design

- Incorporates both AFC and VAFC functions in one unit

- 16 point fuel correction

- Color FED display

- User defined button and background colors

- Inverted "anti-glare" screen

Key functions include:

MONITOR MODE-

* RPM

* Throttle

* Battery voltage

* Correction %

* Air flow %

* Pressure

* Karmann

* VTEC

SETTING MODE-

* Air map

* Air map graph

* Throttle point

* Deceleration air

* VTEC control

* VTEC unmatch

ETC MODE-

* Model select

* Mode select

* Car select

* Sensor select

* Analog scale

* Warning set

* Display set

* Sensor check

SAFC II

- knock sensor

- less load points

- old design shape

The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The S-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. The S-AFC is capable of monitoring and replaying the following data channels in Numerical, Analog Meter and Graph displays: Intake Manifold Vacuum/Boost Pressure, Air Flow Capacity, Intake Manifold Pressure, Karmann Frequency, Engine RPM, Throttle Position, and Air Flow Correction %.

Gizzmo CamFC

- made by apexi

- looks pretty plain and simple

- no monitoring functions

- who can tune it?

- less wanky

- no knock sensor

The CamFC has an AFC (air/fuel controller) onboard so that fundamental fueling issues related to the addition of tuning accessories such as extractors, exhausts, adjustable cam gears, filters and mild cams can be resolved. The cam switching point is adjustable in 1 RPM increments and the switch off point is adjustable as well.

The AFC is adjustable in 500RPM increments and the switch off point is adjustable as well.

The AFC is adjustable in 500RPM increments and automatically interpolates (averages) between these points. For non-adjustable cam vehicles, the CamFC can be used to its AFC and tachometer features while the cam trigger output can be used as an RPM switch for NOS, shiftlight, high boost solenoid, etc.

CONCEPT:

Gizzmo's AFC/Cam controller is the one stop solution to solving basic fuelling issues and cam switching points on any car.

CHARACTERISTICS:

AFC RPM range: 0RPM to 9000RPM

AFC RPM adjustment range: 500 RPM

AFC adjustment range: +/- 40%

Cam adjustment resolution: 1RPM

Tachometer resolution: 1RPM

Unit size: 117mmx57mmx26mm

Conclusion

At the moment i'm leaning more towards the CamFC, it seems to do air/fuel control and control cam switch on and switch off points.

has anyone tried the camfc? and can anyone shed some light as to how they'd rate it?

cheers

[rev210]

Hang on mate!

Extra load points are exactly what you want!

[Eug]

the SAFC interpolates between each load point anyway, obviously more is better to give a finer tune.

but are the other features such as cam adjustments more worthwhile?

i also cant seem to find the number of load points for the CamFC (assuming it's every 500rpm from 0-9,000rpm = 18 load points??)

cheers

[tmc_2]

U will find u dont need the extra points, and th esafc interpolates between points. Id be gettgin the safc2. I did have a neo but didnt tneed the load points. Just get the safc2 as it has knock wich is a handy guide.

[Pauly33GTS-t]

what about haltech e11?

[JieLine]

I got the SAFC Neo cause of the colour screen...

[Eug]

no one has anything to say about the cam switch on/off feature on the gizzmo camfc???

where it be they've tried it or not, or have any opinions, etc.

is it more suited to having aftermarket cam shafts?

theoretically if it doesnt knock on the dyno whilst tuning, it shouldnt knock any other time (and in my case R33 GTS25) there's not much risk of knocking.

since SAFC2's and SAFC Neo's are around the same price...

[GorGasm]

Thats because you cant use it.

cam switching is for Vtec/mivec/other variable cam engines. A Cam FC provides similar functions to an Apexi VAFC.

Tuning a cam fc is the same as an SAFC. Anyone with a dyno can do it.

The SAFC is a better unit as it has a knock input and a monitor.

I thought the neo did have a knock monitor? Anyway, if you arent going to play with the settings on the road then you wont need the knock monitor.

[Eug]

oh right.. i'm thinking about variable timing... my mistake.

looks like it's down to the neo vs. safc2

thanks.

[rev210]

I used the 'extra load points' on the SAFC Neo, why wouldn't you? There still aren't enough of them but, for the money it's as good as you get. Like I said the choice between S_AFC II and Neo is easy, the SAFC II doesn't have as many load points as the Neo therefore the SAFC II isn't as good.

[humble]

sorry to dig up an old thread but doesnt the AFC NEO have a sensor select??

could you not select Knock in that option???

[Basti]

bump. i'd like to know the above too

[QWK32]

bump. i'd like to know the above too

the sensor select menu isn't what your thinking it is. when you go to sensor select you get option relating to the setup of you afm and throttle. eg. when throttle is pushed does the signal voltage increase or decrease (skyline is increase) and if you are running 2 air flow meters in gtr's or if you are running a z32 or q45 afm. nothing to do with the knock signal in this manu. safc2 has a knock signal readout and but the neo doesn't have that option.

[icemm]

I owned a neo, i would have loved the knock sensor, you will find you don tneed many load poisnt to modify if u dont have any problems wiht ur car. I know have a PFC and recomend just going for that.

hi ) i have NEO and need some help with it. (settings.) can you help me? we have no tuner here thats why a need help. thank you
