apexi safc II tuning HELP!! Options

[brommy02]

Ok my car is way too rich so my turbo only spools until 4500 rpm then blows black smoke out my wastegate. i have an apexi safc II but don't know how to tune it and nobody around me can either. if anybody could help me that would be great thank you.

you really need to get a wideband, and even better, get the car on a dyno to tune the safc properly.
with that particular setup, which was basicly a copy of shannons (supershannon77) setup, your gonna wanna setup the RPM points to look like this:
800 1200 2400 3000 3400 3800 4000 4200 4800 5200 5800 6200

i cant remember if it gives you 8 or 12 RPM points, if it only gives you 8 points, go 1k, 2k, 28, 36, 42, 48, 56, 62.
then in the lo throttle your gonna wanna be at like -16 or -20 at all the throttle points below 3600rpm. above that, set it to -15.
in the high throttle your gonna wanna have it about the same, but would go to around -12 or so right after 4k rpm, and tune it from there to get it to around 11.5:1 under boost.
your also gonna wanna set the crossover point which i believe is called "NE point" or somthing like that in the menu to like 25 or 30 lo and like 40 high.
what that does is control the point at which the SAFC will use the lo or high throttle map, according to throttle input.
so, with the settings i mentioned above, anytime the throttle is below 25-30% open, the SAFC will use the lo throttle map, and anytime the throttle is open more than 40%, it will use the hi throttle map. (it interpolates in between the 2 settings.)

that will definetly get you in the ballpark for that setup, provided it is setup the same way it was originally.
can you get some pics of the engine bay and post them?
