Hey guy,

can someone give me a hand, i am going to install the safc tomorow although,

the manual doesnt match the wiring coming out of the safc lol so i am a lil confused.

can someone take a pic of there ecu and tell me what wires go where. or give me a lil run down.

few things i am unsure about is what wire should be going into the throttle wire on ecu. and someone told me a whire should be going into the knock sensor wire on the ecu also, but this isnt in the manual.

which makes me confused.

my car is a r33 gts-t

thanks

G'day,

I recently wired a SAFC (blue screen version 1) into my ca18det S13 so I can give you my experience with this unit and hopefully answer some questions. The SAFC doesn't have a knock sensor function (the SAFC2 does) so you won't find a wiring diagram showing it.

Your SAFC should have 10 wires - red, green,grey,black.brown,yellow,white,blue,pink and orange. For your R33 gts-t you won't use the blue, pink or orange wires. The grey wire is the throttle position sensor input. Red is +12V power, balck and brown are ground, green is RPM, white is AFM input and yellow is AFM output.

I recommend you go to the Apexi website www.apexi-usa.com and download the 2 PDF files from the documentation page called electronics_safc_ins.pdf and electronics_safc_wire.pdf. These contain all the information you need. Make sure you read all the warnings before you attempt to install it.

Hope this helps

Kris

i just installed my safc on friday night. d/l the 2 pdf's and its alot easier. it has 2 diagrams for rb25, one for ser 1, one for ser 2, however they are both the same.

also look closely at the wiring and the locations in the connector. there was a few times i questioned which wire it was.

dont rush it and u'll be fine.

cheers

Linton

if you are not busy today i could have a look at it for you as i fitted one to SKA's 33 gtst not long ago..

if your afm isnt workin you would have had troble before you fitted the safc-1

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
