ok i need to know how to tune my 1988 rx7 n/a it has a apexi s-afc-2 someone help please. thanks guys

 

Is it hooked up correctly?

What do you want to tune with it, just fine tune the AFR's?

On an n/a I believe to start I'd lean it out SLIGHTLY in the top end, like 5%..

To do it properly you really need an EGT, wideband or learn how to read plugs (and be willing to pull/clean them every 1/4 mile to see your results)

If you search there was a guy on here raving about his gains with an SAFC a long time ago, I think he leaned out the top end alot.. But I don't remember, search for the info and you might find it. This was back in 2004/2005 probably.

 

ok thanks man. and dang...you got a skyline??? whats the most i can crank out of a n/a 13b?

 

you'd definitely want to use a wideband o2 to tune it, most dyno's have them

 

depends how much u put into it

ive seen some rediculous numbers from na's
what all do u have on it now

 

well i just bought the car 3 days ago lol the emissions stuff is removed dual beat racing exhaust the air fuel controller. umm i have no clue what else. all i know is that it pulls hard. i kept up with my friends 1989 ford taurus SHO 5 speed. my rx7 also has a limited slip rear end. it came with the stock rear end in the trunk though lol

 

prob do some tranny stuff, short shifter, clutch and press.plate

the third rx7 i had came with a jet chipped ecu, that was pretty dope...
u have headers and and anti stock cat?
