I know piggy-backs and other ECU topics are always popping up, but I am looking now for the comparison of these 2. After looking around I have fallen on these - I am not upgrading the turbo thus this piggy-back will be running with:

- FMIC + Exhaust

- Fuel pump and FPR

- AFM

- Turbo smart Dual stage boost controller

- Stock turb

- Stock new serviced injectors

After looking around I found the main pros for each are:

SAFC NEO:

16x tuning

.... Whats the deal with it supposedly having features over the VAFC?

SAFC 2:

Knock sensor

Those are the main differences I know of, and help would be appreciated. I also apologise for my ignorance of these piggy-back machines :ninja:

dont bother IMO. Get a PFC.

The NEO is just the new version of the SAFCII. not sure about knock snesors If u get the old SAFC (non blue screen) you get ingition control also....thats why thr old ones a re popular.

Well i have an SAFC II and the knock is great, and it works, if you know how it works.

I have a Central 20 ecu and an SAFC II and got 207 rwKw at 12 psi with supporting mods.

SAFC II also gives ignition timing modification, this occurs because as you take fuel out, you also take out some timming with it. If you get one it is best to get an adjustable fuel regulator. This will help in adjustment, as you can add fuel with the reg, but take some ignition out with the SAFC II.

Well this shatter's my reasoning on getting the SAFC II.... Its says the NEo has a knock-sensor?

http://www.racingworks.com/apexi_afc...controller.htm

Also, I've been talking to a few ppl - what would I do in regards to getting the ECU played with?? Would I get the same performance etc as using a SAFC? For the same price - ie ~$500 total

I can confirm 100% the neo has no knock read out. I reckon if you only have $500 to spen the safc2 is prob your best bet. Remapping ur stock ecu will be more expensive.

I was in the same boat as u 4 months ago and i got a neo and now have a PFC , i think you should just save up and get the big daddy pfc to have it done righ tthe first time.

Yeah problem is with PFC or E-manage I'm easily looking at 1000-1500 buckaroos... specially since R32 PFCs are near impossible to get atm second hand, and I'd need a E-01 or something to go with the E-manage Ultimate.

How much would the re-mapp be?

Central 20 ecu ($200) + SAFC II($350)+tune($200)=207rwks at 12 psi on stock turbo and a bucket load of midrange. The ecu i have will support large turbo and the SAFC II will drive any airflow meater, so i am good for another 40 rwKs or so.

a guy buy the name of mad82 i think? is selling a modified stock ecu for like 200 in the forsale section, u should buy that then get a safc2 or neo to make it just right! his ecu has no rich and retard no speed cut and 500rpm more rev limit, i think also slightly different mapps! Id go for that plus safc if on a budget.

Unfortunately that ECU is R33 not 32 :woot:

Hmm if u have a 32 u can ge tit remapped, i think its still like 600-1000 to do tho.

Id prob get a NEO or safc2, then reevalutae it u thin ku need th eITC or a remap, if u buy a second hand safc2 or neo u can sell it for pretty much paid for it if u dint like it.

the neo has a higher resolution map, but you dont really use it anyway since the SAFC autmoatically interpolates between the points.

Neo looks a bit nicer and is new.. aside from that, many people will tell you it was a step backward from the SAFC2 which had the knock sensor and the ability to have multiple maps as well.

If you can dig up a nice safc2 2nd hand, get it, else the NEO will perform the same task, but ur missing out on some peripheral features.

the interpolation is better when you need less of it. Hence the extra map points are more important than a knock sensor from a tuning perspective. The S-AFC is a fairly blunt tool to begin with without ignition mapping so if you have the choice take more tuning resolution.

I could have got got either but, went the Neo. It's a short term thing anyway.

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).

    • Maybe I also should have wrote that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂
    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
    • Hence why I said earlier that I don't think the turbo Neos ever would have actually qualified as an LEV. I suspect the only actual LEVs that came out of Nissan were the NA Neos. Still call them all Neos. They all stil have the Neo-ness. Just that they don't all qualify as as LEVs.
    • It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car
