Hey

I've been searching for a while now and keep coming up with the same old descriptions and specifications

I just want to know what the main differences are between SAFC1 and SAFC2.

I presume the SAFC2 has more load points and obviously looks different so the SAFC1.

Can someone post up some specifications..

Would you say the SAFC1 is now outdated and best to go SAFC2? I am having trouble finding one at a reasonable price and have bought an SAFC1 now.. but not sure if i should use it or what.

I mean, if there is a major different between V1 and V2, then yeah, but if its the same shit then I will just use SAFC1.

I am also referring to the blue screen SAFC, not the ancient dial version :pirate:

Don't know how much of that makes sense, I'm pretty tired, hungry and out of it, lonnnng day today..

Thanks in advance,

Abu

Basically the SAFCII has a knock sensor and the extra load points and a scroll wheel instead of 4 buttons. In the end they will get the same result - dunno how much the few extra correction points make to real world performance as the safc creates a smooth curve between points. The monitor mode may be different as well but essentially the same. I just bought the number II cos i wanted one brand new with manual etc - and for the knock but i dunno how accurate the knock readings are anyways.

safc1 has 8 correction points that can be adjusted in 500rpm increments. thats about all it does.

safc2 has 12 correction points that can be adjusted in 200 rpm increments and has the ability to run 2 maps (usually 1 tuned, and the other standard) and it has the ability to minitor knock.

safc NEO has 16 correction points, VTEC controller built in (i.e. VAFC built in) as well as all the features the safc2 has but has a colour display that kind've turns me on.

That is the answer I was looking for.

So 2 maps, 1 standard. So pretty much you can switch the SAFC2 off and you will be running off standard ECU.

SAFC NEO with the 16 points is another advantage, as well as the SAFC2 features..

Although I am just looking for something basic to do the job, so SAFC2 would be good, because I would like to have 2 maps, standard boost and high boost would work?

Time to weigh up prices and see whats available!

Thanks for your help man, much appreciated.

Neo also has no knock sensor.

the knock sensor on my safc2 was a life saver. i turned timing over a bit too much, i saw it hit 99 then started to hear a little pinging AFTER.

i set it to flash if it went over 40 knock, otherwise i would've have known and blown my motor to bits..... again.

Hahaha lucky hey.

Hard to find a SAFC II for sale, been looking pretty hard..

What mods you got and how much power you making with the SAFC II?

Thanks,

OK so I got me an SAFCII but the whole thing is in Japanese, as it would be lol

Anyone have a English manual for one of these by any chance?

Thats the DIY I found on doing the installation so I will be following that.

Also just want to know how to set it up to run stock fuel map until I up the boost and can take it to a dyno to get it tuned?

Thanks,

Abu

in one of the menus there will be an option to "initialise". that will delete all data that has been input into the unit.

i recommend doing that and starting from scratch.

OR you can scroll through and find "file select" or something like that. this will allow you to choose between the 2 data files by going to the column which says "ON OFF" and pushing the joystick up or down to select.

this is all off the top of my head so follow it only as a general guide.

You can have it all prepared/installed as in have it clipped, femal/male plugs attatched and then plugged back into the original position. All powered up and running too.

Then when ready to tune, just unplug that 1 wire and re-route the signal to go thru the SAFC unit.

If you use the plugs supplied, no further soldering will be required to make the signal go thru the unit or back to the original position.

It'll make sense when you are doing it, I'm crap at decribing it at 5am.

Thanks for that man. Will have a better look now that I am half awake and sort of know whats going on.

Are you saying plug the male and female plugs that go into the AFM into them selves?

Once you install the safc it will just run the stock fuel map because no correction has been applied to the load points. You can have it fully installed and driving around and all it will do is display values such as throttle, air flow, knock etc. If you install a brand new safc it is fine to drive around with it untill it gets tuned because it hasn't changed anything. Otherwise if it is used just check that in the 'settings' onder 'high throttle' and 'low throttle' everything is on zero correction and you will be sweet to drive. Don't have to worry about disconnecting it etc. :)

      Rusty roof repair

      By GTSBoy · Posted

      A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway.

      first time swapping rb25det into r34

      Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too
