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.

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.

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

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

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...

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.

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.

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.

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

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
