SAFC II Tuning questions?

viprdude · 08-29-2007, 01:30 PM

I only changed the high throttle maps on my car for tuning. this is my daily driver so i need the best of both worlds here.

Right now i have high throttle kicking in at 65% and it leans out the mixture a whole lot and ends up with about a 13.5:1 a/f ratio. i know that is golden, it was tuned with aid of a wideband.

for the lo throttle, i did not make any changes to the fuel curves, it is at 0 across the board, should it remain this way?

I also have an SAFC II but my car is stock....ive heard that i shouldnt change any of the settings since i have a stock fuel system...is this true, or is there anything i can tweak to give me a little better performance?

Sorry i couldnt answer your question but there arent too many threads regarding this piece of equipment...

i have found out my answer. i have stock mostly everything also.

the only time when it makes a true difference is on high throttle or when you are going over the threshold of whatever high throttle is set at. the car normally ignores the front o2 sensor when you gun it and this is where the s-afc II takes over.

i have mine take away alot of fuel on the hi throttle setting, i left lo completely alone and have lo throttle at 15% and hi at 50% currently.

how does that work out for you? Any seat-of-the-pants difference?

yeah def gains. +10 hp easily.

car ran rich as a pig when the rpm went past 4500. all that is gone and pulls hard in every single gear. i wish it had 2 more geras for me to go through!
