I plan on installing my injectors this weekend. I got the 440cc ford ones. I already have my s-afc hooked up and working. I know I have to drop the idle pressure down to about 40 when the injectors are installed. Do I have to adjust the boost fuel pressure? Can someone explain about the settings on the s-afc. Like about the high and low throttle settings. Can someone make up a breif "how to" on getting started tuning the s-afc.

well once you set your idle fuel pressure, you should do like -40%-42% at the 1000rpm on the low/high to get your car to idle... it might take a few turn overs but it will start up... well 1st off make sure your Th point % is set.. and the low setting refers to anything to the low Th point % and same goes for Hi...

Dave, look under the main page's mods section, and check out Guy's write up on tuneing the SAFC for the 420A. it should help you out a lot. the lo-hi throttle percentage settings vary for every persons driving style. you will set hi and lo settings, and the % settings for hi/lo tell the SAFC when to make the switch over to these settings. in between the two selected numbers, it does a mathematical equation, and averages them out. i have mine set at 35%-lo and 65% hi.

i'm almost positive that guy's link doesn't work anymore. he redid his site i believe. maybe someone saved it? well i would like a nice right up.

Heres the link.. http://www.2gnt.com/www/files/SAFC-tuning.htm#Introduction
