Tuning A/F for setup
I know there is a specific section in the forum for this but i posted like a week ago and i still have gotten no replies because not as many members go in there for the hell of it.. So here is the story. I am getting an s-afc to install along with my FMIC. Right now the car is running about 10.5 lbs of boost and i expect that to go up alittle with the FMIC. Is anybody running a stock turbo with a similar setup and can tell me what their settings are? I am very unfamiliar with tuning with a piggyback. My secondary injectors have been upgraded to 680's.

You need to run it with a wideband or EGT to do your tuning.

Yeah i understand that i was planning on doing so but i can't do that right away so i was wondering, even if my car runs a little rich, what would be some safe settings until i can tune it?

Yea, I wouldn't drop it at all, keep it default. You don't even want to go a little lean, cause in our cars, detenation = death. Most piston cars can take quite a few dets before completely being busted, but our cars, it breaks stuff pretty hard.
Keep stock until you can get a wideband, or get to a dyno shop.

I am not stock... My car runs just a smidge lean as it is because i am boosting almost 11 pounds. When i put the FMIC that will go up more so i need to adjust my fuel which is why i am getting the s-afc in the first place.. I want to turn it up to a safe setting even if its a little rich i dont mind wasting more gas than i need as long as my motor doesn't pop. When i can tune it, which will be soon anyway, i will do it. So how much should i increase fuel to be completely safe? Oh and remember my secondary's are 680's.
Thanks

Dude, you have no idea if it's running rich, lean, or whatever without a wideband, either on the car or on a dyno. Drop the $100 for dyno time or drop $300ish for a wideband.
Some people are running pretty good with upgraded injectors and hardly any SAFC correction. Others are running lean (I am one of those) and many are running way rich.
