SAFC and 550/560cc guys chime in please!

[phillabaum03]

Hey guys im not gonna lie, I dont know shit about tuning with a SAFC, and my 95gst has one and I put 560cc evo injectors on, a 255 fuel pump, and a 16g since i've had it, just to name a few things but my cars running real rich. In the 10's on part throttle, I was gonna see what you guys have your Lo-throttle and Hi-throttle corr.'s set at as well as Dec-air? Pics would be the easiest for both of us but any help would be greatly appreciated guys. I'm really trying to lean it out. Full throttle is still a little rich but mostly low throttle. Please give me your .02cents fellas

first off you may need an adjustable fuel pressure regulator.

255's often overrun the stock unit and cause you to run rich.

if you are running 550's you should set your LO side to -18% since they are that much larger than the stock 450's

560's are 19% larger so you would set those to -19% on the LO side.

these #'s are to be set across the board to give you a start.

then use your wide band to make corrections as you drive.

I have 560's and they are set at -18% across the board and i get 23mpg.

as far as Hi settings you need to do A LOT of highway pulls while logging, or just go to the dyno.

hope this helps.

-19 threw all lo throttle RPM's?

You can't go by someone else's settings and expect it to work for your car. They might have a perfect tune that will knock like crazy if you try and use it with your car. You have to do your own tuning.

Before you start, make sure you have covered the basics, such as plugs, wires, timing belt (if needed), boost leak test, fuel filter, etc. You're going to be pushing your car hard while tuning and you want her to be in tip-top shape.

Decel air doesn't work properly on our cars, so you can forget about doing anything with that.

Have you set your FT's properly? Once you get that done, set the Hi throttle map to -15% across the board and make a 3rd gear pull from 2.5k to redline. Log timing, knock, IDC and rpm only to maximize your samples/second.

Also make sure your sensor type is set to Karmen, with the arrow pointing North East and set your TPS trigger points to 30% and 80%.
