Default chipped ecu/3bar/safc?

ok quick question. i have an ls swapped crx. we ran 9psi on afc hack for a while, ran awesome, no probs. now, i have done the obd0 to 1 conv. and had a chip burned at phearable.net turns on and runs like a new stock honda. awesome. turned the boost up as far as 15psi to get afr where i wanted it. (about 11.8 afr). now for the track (road course) i want to run 9-10 psi. only thing is it'll be rich at that boost. i still have the s-afc hooked up, so i can pull fuel with that, BUT, with the 3 bar map, will the afc work right? the safc is zero'd out right now. i'm thinking i have to change the in-out settings on the afc right? i found an old post from '05 where i guy said to set them @ 14in / 6 out. does that sound right? remember, i'm not actually doing the afc hack now that i have a chipped ecu, i'm just using the afc for a small fine tune. (what it was designed to do) also, if needed i have a msd boost/timing master (retard) that's zero'd out right now), if needed. that's how we ran the afc hack for 2 years without a single issue. sorry, i guess it wasn't a ''quick'' question.

Your ecu must be mapped for what ever map sensor you are currently running.
The afc must be tuned with what ever map sensor you plan un running also.

let me clarify, i have a 3bar map sensor with a phearable.net chipped ecu mapped for the 3 bar. i want to ''lower'' the boost, so i will need to pull some fuel with a safc. do i need to change the ''in/out'' settings (voltages) on the apexi?

First things first you really should not be using the SAFC with a chipped ecu to be completely honest. If your car is running rich why dont you just have it tuned? No need to try to lean it out with boost.

The SAFC has been proven to add timing on a honda with a distributor if you pull fuel which in this case may not be to feasible in a boosted application.

Is this a basemap?

John(the owner of phearable) replied above, have you tried to contact him? Im sure he did not send you that map under the impression you would be using an SAFC on top of what he has setup for you.
