KA-t SAFC2 Settings wanted! (t25)

[2chuki4u]

What are your settings?
-Post setup,settings, and degree of timing.

My setup is:
T25
n60 mafs
370cc inj's

i need a base setting tune please! ive looked all over so help if you can!

Simple math.
370 x .73 = 270

So your new injectors are 27% (1-.73=.27 or 27%) larger then your stockers, take out 27% fuel on low throttle map to get it to idle.

-27 across the board on low throttle pretty much

Then just get a wideband or get on a dyno and tune the high throttle map, set decel air function, etc. etc.

Everybodies settings are going to be different.

I also forget the MAF correction but you can probably find that in a second.

im trying to sell my plug and play safc neo harness if anyone wants it. Props to prok0 for being cool and actually posting something helpful.

This is great advice, and coming from a previous T25 KA-T owner I would follow what he's said here. The Stock S14 MAFS can handle 7psi btw... Once you hit 10, you'll max it out and go to full rich.

i can see what hes saying by subtracting 27% out of my low throttle IF i had a stock mafs. but im running a n60 so shouldnt i set it at 0?... see thats whats got me right now. but otherwise, yea i do appreciate the help. +1.

byt the way im s13 not s14

I think the whole deal with the n60 maf and 370s was if you were running a stock ecu without the AFC.

I remember reading some shit about different maf housing sizes, etc. to get it to run properly.

But you have the ability to change your MAF input type in the afc to in essence 'trick' your ecu into reading the n60 properly...

Also, maxing out the stock maf really isnt that big of an issue, mine was maxed out pretty much once I got into boost on my KA-T, but it made it kind of nice since maf voltage stayed constant it made tuning with my wideband really simple.

So yeah, -27 and then just do the MAF correction deal, under the MAF table it should say like __ In __ Out, and you just have to put like 2 in 5 out or w/e corresponds to the MAF you have, I cant recall off the top of my head what the settings are for n60...

[yoni_nismo]

you could run a n60 with 370cc without a safc just retard your base timing to 15deg a friend ran this for a while before getting a tuned ecu.... try to get a dyno run with afr readings before you start pushing your car because every motor runs diffrent so dont copy someones safc settings.

for changing the maf sensors you would need to know the correlation between the both voltage quantifier maps
