Safc1 Vs Safc Ii

[abu]

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.

Ah awesome mate, thanks heaps.

I hooked it up to a power convertor and have been fiddling around with the settings to get an idea of how to set it up! Very interesting, and has a lot of features. Slowly getting the hang of it.

I will reset it, and check the settings under high throttle and low throttle before I start the car up.

Will have a go at installing it sometimes early next week when the car arrives.

Thanks for your help.

Go to www.apexi.com.

Select the picture on the left (America)

Select 'Support' at the top right of screen

Select 'Installation Manuals'

Select 'SAFC II Instuctional Manual (401-A911)'

That might be what you're after

Thanks for that man.

FOG35 was nice enough to PM me the 2 x PDF files for installtion and configuration.

Thanks,

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

Thanks,

When you check the instructions, you'll notice all the wires are only tapped into to get a reading from, like throttle postion, knock etc.

Although, the one wire that has the Air/Fuel signal is the one getting altered so it's not just tapped into, you CUT it in an appropriate spot and route the signal thru the SAFC to fool the Nissan ECU.

So get everything done, cut it and attatch the male female plugs supplied which is then supposed to be plugged, 1 end into the SAFC, and the other end out of the SAFC.

But if you're not using it yet, just plug the female/male plugs you made up back into the original position, so that the wire and it's signal is unaltered (except for 2 plugs now in the middle) and not going thru the SAFC at all.

Everything else will be fine and showing the other readings.

The throttle pos sensor is the best

BUT, as someone else said, there's somewhere in the menu to turn the maps off (which i didn't know) so just do that if you want.

Have fun!

Ah I see now sort of! Its making more sense. I will have to read over that again and follow the steps in the wiring diagram to ensure that I get it hooked up correctly.

Pretty straight forward though, wont take long at all.

So if the SAFC II is reset or is brand new and never used or altered, I can plug it in and it will run my standard fuel map unaltered, as long as the 'settings' under 'high throttle' and 'low throttle' is on zero correction?

Just confirming before I break some shit! lol

Thanks guys, been a really big help.

Yep, exactly what you said

Although, even though it's straight forward, be prepared for some gravel rash on the knees...haha

It's a bit fiddly and in a tough spot to work on.
