sup guys i have done some pretty serious engine mods recently, >_< and need to upgrade my afm.

is it possible to run the z32 or q45 off the stock ecu with a SAFC?

dont even think about saying "buy a pfc" ITS NOT GONNA HAPPEN :):):rofl:

would like to know if stock ecu (remapped or standard) and a SAFC will run it.

please only have clear answers

cheers :)

Hey buddy

The SAFC is a fuel only computer, so short answer no you wont be able to run the Z32 off it. That also applies to after market injectors.

You can run the Z32/Q45 with a REMAP ECU with no issues, but if you were to go with a REMAP or any form of after market stand alone ECU (WOLF, MICROTECH, PFC etc) there would be no need for a SAFC as the REMAP, WOLF, PFC, MICROTECH will do EVERYTHING for you.

An SAFC is only a fuel only computer, piggy back, which alters the signals from the ECU, where as a REMAP is basically a full retune of the standard ECU.

Hope that helps.

I'm pretty sure these units have the ability to change the airflow curve to suit a different MAF.

Its worth reading up to find out.

Got any links to the documentation on these units?

I got heaps of shit at home man, manuals etc but currently at work.

I remember when I bought my SAFC II, I was assured that Z32 wouldn't be supported along with after market injectors.

SUPER AIR FLOW CONVERTER is what SAFC stands for, which does actually imply in a way that it should be able to configure a Z32.. according to air flow signals.

But it's all a bit technical for me.

Will get supporting documentations up for everyone tonight once I get home.

If you've done enough mods to warrant a bigger AFM.

Then that also warrants a decent ECU. Not a band-aid like a S-AFC

That is true.

An SAFC is just like a temporary solution/supplement... best to get a tune done, that will show the best results/gains.

Even a piggyback ECU such as E-MANAGE will show you good results at a lower cost than say a PFC.

that's not right mate. SAFC alters air flow signal which actually affects fuel AND timing. and yes it can be used with a Z32 AFM on an RB25 and can probably cope with larger than stock injectors. so will it work? yes it will. is it ideal? no it's not. if you are upgrading injectors and AFM then something like a Power FC is a wiser choice. but if you are set on it the SAFC II will still work.

safc II can convert a z32 afm signal to a signal to match your car, its part of the setting up. it asks what type of signal is inputted and what signal you would like to output. and you can run larger injectors, the safc has nothing directly to do with them, just changes afm signal and then the ecu changes its output signal to the injectors. one thing to keep in mind is like what Beer Baron said, your timing is also effect by these changes.

safc is only ideal for slight afr changes, like a tune for a car with exhuast, air filter, fmic and boost up a bit.

whats your reason for staying with the stock ecu?

wow lot of info there, thanks guys.

the SAFC is the series 1 SAFC not the 2nd one.

will this still work?

also, i would like to get a pfc, but feel it is a waste of money as i am only aiming for 260+rwkw, i know it is always good, but dont want to waste the money on it.

although, if the price is right i might consider it

so will a safc 1 work with a z32, also i am putting in some 550cc injectors aswell, been told by chapmans that they do it all the time.

anyone out there actually done it>????

thanks for ur advice guys

you dont judge if a powerfc is justifiable or not by rear wheel killowats

its judged on user ability, car response once tuned and how it performs over all

ive got a powerfc at 190rwkw and its the best thing ive done to the car of all of my mods

i couldnt recommand a stand alone ecu (setuip correctly) high enough out of all the mods anyone would do to a skyline

sure if powerfc isnt your thing, then go greddy or remap or motec or autronic or link or SOMETHING etc etc

the point is, get a real ecu or remap the bastard and the car becomes a new car

once all the load points are tuned (regardless of ECU) the car should drive like a different car

thats what you pay the $1000 for. for the amazing throttle resspone, for the good economy, for the rapid boost build and torque when u need it

forget about rear wheel killowats

if you go for 260rwkw with injectors, afm etc and you do actually get it working properly (good luck)

you will spend ages mucking around, the tuner will get angry and take longer (cost $$$)

and youll end up with a big comprisemise and you have to tippy-toe around deontation cos the piggyback dials in more timing automatically (part of the nature of bending the afm signal)

by all means do it and save $1000 etc but another guy with 220rwkw and a good tune on a real ecu will smash you in all of the usual comparisons, average power, ramp up power, boost build, lag, response, ability to smoke tyres etc

the tune is the biggest thing here, get that right, and the car should be the best, regardless if you use 480cc or 520cc or 11psi or 13.34psi etc etc...

omfg, you thoguht you were going to "omly" go for 260rwkw with a safc1?

Your delusional.

You're only option is a powerfc or other standalone ecu. I don't even think you'll be able to get a Re-map to suit that sort of power level.

we'll see, stay on topic mate

well, looks like i will go for a standalone ecu:blitz, mines.

NFW am i buying a pfc. every man and his dog has one.

and yet, they are hell expensive.

easy to say buy one if ur not a uni student, and a casual employee. BE REALISTIC

i will look into a standalone ecu. any suggestions would be sweet.

ps still want to run safc

Edited by r33cruiser

anyway you have enough info to make an informed decision

if you have a local remapper guy and he is ok with doing injectors and afm go for it

it will be much better than the safc comprimise

we'll see, stay on topic mate

ok you are set in your ways so i will stop caring and offering advice at this point

but dont buy a blitz or a mines ecu, they are pointless as there are no mines or blitz tuners in australia

so you may as well stick with the stock ecu and just be done with it.

get a locally supported ecu and get someone to tune it correctly

every man and his dog has a powerfc because they are the easiest, cheapest, quickest, well supported and best bang per buck ecu

sure motec is great but for 3 grand why would when you get the majority of the crap you need for 1k instead

if you are looking at a stand alone ecu look at;

apexi powerfc

greddy emanage (remap piggyback)

link ecu

wold 3d

autronic

motec

hks fcon

but as you will know none of those come cheap, as they are standalone systems

and if you do go for some exotic ecu find out how much for tune and how many workshops can support it

if only one workshop in aus supports it then whats the point, its gonna cost you 10 billion $ for a tune

we'll see, stay on topic mate

every man and his dog has a pfc for a reason.

Your going on about 260rwkw's but then saying your a uni student and casual employee. It'll cost u money to make that power and u NEED a stand alone computer of some sort, its not a luxury in your case its a necessity.

haha, alright cheers man i do appreciate it.

i just installed a turbo, pump, reg, clutch, diff, safc, injectors, z32

and would like to get as much power out of that as possible

been told by chapmans i can make 260kw...

cheers guys, u can finally lay this one to rest

its always funny to see the old codgers get rilled up because they think that their way is the only way to make HP.

anyway guys see ya at a later date

Paul is right, is a waste of time trying to help this guy. Buying an ECU to be "different" is the dumbest thing I have heard since trying to run a RB30 crank in a RB26 block. Let me guess, you painted your car a special colour to be different too?

Go on, tune your SAFC to run 260rwkw, I dare you. I bet you spend more money than a powerfc costs trying to get it to run properly.

f**k some people on this site make me laugh.

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
