Stock KA SAFC MAF setting question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

1985zcar · 08-11-2007, 09:09 AM

What's the MAF In/Out? I know it's Hotwire-5 and the arrow is up right? But I'm unsure of the In/Out...is it 5 in 5 out or something else?

5 in 5 out and make shure the arrow is facing up to the right if its a stock mass air flow if not for example n62 maf 2in 5out
cycle is 4, arrow pointing up to the right

yeah I was KA-T with a N60/370 combo but yesterday we took all the turbo parts out but I still have the SAFC II in...so I just wanted to make sure I had it set right. 5 in 5 out arrow up to the right. Thanks!

im pretty sure im running 1 in 1 out with stock maf and it works good

juniorjimenez · 08-11-2007, 10:43 AM

its going to be 5 in 5 out with stock maf

Here a list of HW numbers I made back in 2003

HW= Hot wire BTW-----------The number after indicates the number that needs to be inputed into the SAFC (sens.in).

If you don't all ready know, the way the number system works is the lower the number after the MAF the more the airflow the MAF can measure.

All SR20DE cars are HW6 and most SR20DET are HW6 with the exception of the following being HW5, the RNN14 GTi-R (230ps) and the W10/11 Avenir (230ps) and S14/15 Silvia.

Here goes a final list of Model / Chasis / Engine / Year / Hot wire codes:

300ZX Z32 VG30DE 90 - 96 / HW-2
300ZX CZ32 VG30DETT 90 - 96 / HW-2

Skyline GT-R BNR32 RB26DETT 90 - 94 / HW-3
Skyline GT-R BCNR33 RB26DETT 95 - 98 / HW-3
Skyline GT-R BNR34 RB26DETT 99 - Present / HW-3

240SX S13 KA24E/DE 89 - 94 / HW-5
240SX S14 KA24DE 95 - 98 / HW-5

Sentra SE-R B13 SR20DE 91 - 94 / HW-6

Maxima A32 VQ30DE 95 - 98 / HW-4

Altima U31 KA24DE 95 - 97 / HW-5

Q45 G50 VH45DE 90 - 96 / HW-1

If you are using the stock ECU and stock MAF the IN/OUT numbers will be the same (ex. for S13 KA24DE IN-5/OUT-5).

If you are using a stock ecu and a z32 maf on a s14 what should it be set to?

IN 02 - OUT 05

Thanks UNISA JECS!

Neejay · 10-01-2007, 12:48 AM

So according to that list, whatever engine MAFS you're using = IN and the engine that the air is going into = OUT?

i.e. N60 MAFS on KA = 4-IN/5-OUT?

Yes 4 IN and 5 OUT would be equal to -

Maxima A32 VQ30DE 95 - 98 / HW-4 ***MAF***

and

240SX S13 KA24E/DE 89 - 94 / HW-5***ECU***
240SX S14 KA24DE 95 - 98 / HW-5***ECU***
Altima U31 KA24DE 95 - 97 / HW-5***ECU***

IN = MAF

OUT = ECU

Neejay · 10-01-2007, 01:03 AM

ECU...ok, gotcha. Thanks for sharing the info.

frosti108 · 10-11-2007, 09:12 PM

hmm ok i have a ka24e using an N60 maf. so i should use the 4 in and 5 out like neejay...

BUT im running it blowthrough. so what settings should i use for it then??????? pressure?

also what should i have for the decel settings...?
