45651, S-AFC tuning
Posted by rydereclipse, Mar-01-03 11:21 AM

I just installed the S-AFC and was wondering what hi throttle and low throttle "points" work best. I know every car is different, but I would just like to see what you guys got yours set at, and see if any of you guys could help me find some good start points.

Heres the MODS i got:
Short Ram intake
headers
Denso Plugs w/MSD wires
NOS
intake ported & polished
test pipe
3in. muffler (2.5 piping)

TIA for any and all help guys!!!:P :P

well most people will tell you to let someone tune it for you. i set my high and low points at 50% for high and 35% for low. as for tuning, let a professoinal do it.
later

Hi 85%
lo 35%

pro tuning is rec.

I tuned my own using a blinky A/F but didnt do any drastic changes (6% was the PEAK i reduced it by at only the higher RPMs)

You dont need a pro to tune a SAFC. all you need is a digital O2 gauge. its pretty simple really. Lo-throttle settings, drive around under your set throttle percentage at whatever RPM you are tuning for, and watch the A/F gauge, lean it until the highest number you see is a .94x or in that neighborhood. same way with the Hi-throttle settings. RS_Guy made a REAL good write up on how to tune the SAFC for our cars a while back. it was on the main page, check and see if it still is. hell, if i can tune the damn thing myself, i KNOW you guys can.. :-)

check the review I made on the main board

http://www.2gnt.com/nuke/modules.php?name=Sections&op=viewarticle&artid=52

my low throttle is about 55%, the high at 85%, this is because I don't drag race at 30% throttle and the car's computer does just fine down there with my mods, I need a/f correction at WOT
