When i had mine tuned it did feel a like the power came on alot smoother and according to the dyno sheet i have it was getting alot better air/fuel mixtures and it also did yeild a decent power increase i think it was like 5 - 7 kw though i am not 100% sure.

The main reason i got my SAFC II was because with the few bolt-on mods i had the goold old ecu started doings it typical nissan rich and retard...

In saying that though mine has gone stupid its almost like its lost its settings maybe the connecting is loose who knows but it has gone back to being very rich. When i get a moment i will take it back to a new tuner to get checked out.

My car is sporting one. I found that it partially fixed the missing/flat spot problems through the high rev range and increased power due to the alteration of the previous very rich air/fuel ratios (at that stage running 12 psi with aftermarket intercooler, exhaust etc – my standard R33 computer going into super rich air/fuel ratio mode). Although I feel the missing problem was a combination both the rich air/fuel ratios and faulty coil packs (now they are painted in a pretty blue heat resistant paint and work like a dream).

I wouldn’t be surprised if I gained at least 15rwkw after getting the SAFC tuned, and the power delivery was much smoother as Leech has said above. As I picked mine up second hand for a relativity cheap price it has been a very good value for money modification providing both a good increase in power and power delivery. Hope that helps :)

EDIT: Actually from what I remember (ive got a bad memory though :P ) the dyno run before it was tuned was getting close to 190rwkw (somewhere in the high 180’s at least) and now after the tune getting 210rwkw. Quite a large increase in power…

Alittle bit off topic but does anyone know if the VAFC and SAFC are anydifferent besides the VAFC having to a control for Vtec. And could the VAFC control VCT on a rb25??

Just wondering cos i've been offered a really cheap brand new Apexi item, but I can only get 1 and not a whole bunch.

Check the VAFC application charts on the apexi website (www.apexi.com). I think you will find they will work with Honda vehicles only. They are very specific about only using it with cars on that list “Do not under any circumstance use this product for any car application other than on the applicable vehicles”. Stick with the SAFC eh? :rofl:

I just ordered one then. Got it for $300 plus delivery of $60. Thanks for the replies. Now I only have to worry about who im gonna get to tune it. Any suggestions :(

Pete at Autotech in fyshwick is the man you want to see, he tuned my SAFC, A/F ratios are a bit healthier and i gained 0.6 rwkw to boot

that sounds pretty shit to me... though i guess like most things it depends on existing mod's, engine size, how much you strap it.

When my car was bog stock i was getting like 480 - 490 around town. Since putting the few mods i have on and increasing power i am now at around 450ish maybe 470 on the odd occasion.

I can vouge for that considering i was dumb enough to stand like 10 meters from it last dyno day and get absolutly covered in shit :)

Im yet to find someone to beat me for the sheer amount of black crap on the back of their car :wub: I wash it and its filthy again within 1 day though :D

I put an old school SAFC in my car a few weeks ago (push button type).

My car was previously running 187rwkw with the AFRs sitting at around the 13 mark (pretty dangerous).

After the SAFC install and tune the car put out 206.6rwkw, the AFRs went down to 12 and the powercurve was alot smoother.

Worth the 360 your going to pay IMO.

Then again, different cars get different results.

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)

      Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.

      A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
