and also i want to run 16psi or the max boost to my 14b but having difficulty for proper setting to my sfac. pls help

 

Do you have a boost controller, wideband o2, datalogger or tuned eprom chip? Any of those things are going to helo along with the SAFC.

just have manual boost controller, boost and air/fuel gauge. will that do? /ubbthreads/images/graemlins/confused.gif

 

wide band or narrow band gauge? the little autometer or other company narrow band blinky light gauges dont work except for a very vauge ball park, i used a neo for some time but i just have the GM maf translator.. but im going with DSM link.

 

Then without a logger to measure fuel trims or a wideband o2 sensor to see the a/f ratio(wideband not narrow band like in a bliny light but a real number) you are only guessing how much fuel you are adding with an SAFC. A dyno tune would be beneficial so you could utilize the shops wideband gauge when they tune it for you.

for the mine time i'l just run normal boost and set my sfac (lo and Hi) to 0% or disconnect it?

 

Leave it hooked up for monitoring but leave the settings at 0%.

 

I have tuned my safc with a exhaust temp gauge before I had got my aem ugeo. basically make a full pull in third and if the gauge reads over 14,000 degress C your running to lean just make small ajustments (one click up at a time)to richen it up until it stays under 14k. Kinda crude but it got the job done. remember with an safc theres not much tuning there.

Good luck
