#49733, "s-afc tuning"


          

Can people that have theirs tuned please please put up what points you have your fuel curve at on both high and low? That would be awesome, thanks..I know I should really get it tunned myself but I just want a general idea of what others have it at.

Oh yea i'm running at -16% 1000rpm, -14% 2000rpm, -13 3000rpm etc on high and all 0% on low.
Is that too lean for someone with a high mileage engine and is n/a with only cai and catback exhaust?

What pressur esetting are you running? what approximate O2 sensor voltage are you seeing?

It seems a bit high of a correction factor, but what pressure in/out do you have the S-AFC set at.

okay
in/out i have at 7, pressure setting is the last one, karmen or whatever
o2 sensor voltage is the middle one in the sensors screen right? that one is always around .4 to .9, never seen it over 1
thanks so much man

The SAFC can't read the Karmen count from our cars. You should change it to read manifold pressure, or whatever the SAFC calls it.

The type needs to be pressure.

What are you tuning to then, if you don't have A/F meter? And you may be confusing the TPS signal with the O2 voltage, unless you did the blue wire mod then the S-AFC doesn't read O2 voltage.

If you are NA at WOT, you are looking for .88 to .92 volts at the O2 sensor. Below that and you are lean and could cause some damage.

Do not tune an S-AFC without OA/F Metering, and preferable an EGT!!!

that's probably too lean, at least it will be at high rpms and WOT (the car runs richer in low gears, leaner in high gears)
