Hi there

I am after some info on the apexi safc, like how much more power would u get out of using one and can u tune the car that much more with one with standard ecu. Sorry for my ignorance I dont understand them that much. I have the following mods if that helps.

Nissan Skyline1997 r33 s2

apexi airfilter

walbro fuel pump

large front mount

dump 3in exhaust

splitfire coilpacks

atomic boost controller running 10psi

bov

with standard turbo

thanks

not sure how much power you have now but with a SAFC you can tune the air/fuel and net 250-280rwhp

aorund 200 now? assuming you dont hit R&R

but if you plan for more mods in the future then get a stand alone ecu which can control ignition timing would be better

Most cars with those mods will get between 180 to 200rwkws.

I got similar mods on my car minus the FMIC (only got a SMIC off a 34 GTT) & the coil packs (still on stock ones I think), I got 180rwkw when I got my SAFC 2 tuned at All star garage.

Also my car is a 4 speed slug auto box so theres more power loss at the transmission compared to manual.

i reckon something like a Nistune/Mines/Blitz tuned computer coupled with a SAFC is bomb, that way you have the more agro timing maps, and can still pull/put fuel where you need it!!!

why do you need safc when you have nistune?

Mines/Blitz are tuned in jap land and i dont think their suitable with aussie conditions

I used to have an Apexi SAFC and an SITC (to control timing) and they worked reasonably well but I would recommend a Nistune chip which will give you much better tuning ability for about the same money. Nistune do not make a chip for the R33 so you will have to use an R32 ecu or other and chip that. Do some searching - there have been a few threads on this topic.

If you are ABSOLUTELY sure u are not going to do any more mods except raise the boost 1-2psi the safc will be the cheapest and best bet.

U may just get a few extra max kw but the good part is that you can tune out R&R with it and make the mid range come to life

I had an safc2 along with an adj fuel pressure reg and the exact same mods listed above on my 25 and the car felt so much better to drive without that hole in the mid range

True that ^

But then again it seems pointless. A Nistune board will cost much the same as a SAFC, perhaps a little bit more considering you need the R32 Or Z32 board for an R33. You need a tune on the Nistune or the SAFC, Nistune will be cheaper to tune because it will already have a base image for your car. And then the gains you will get from the Nistune far outweigh those of a SAFC...

    • Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!
    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
