weird issue with safc

[the_momo]

ok....so i have had my safc in my car for about a month now and it worked fine for like a week, then i broke an injector. (maxed it out and it was stuck open). i replaced the 370cc's with 480cc's and retuned the hi and lo throttle accordingly...now it doesnt show any readout for airflow correction as it did before..

my setup is 480cc s15 injectorsstock fpr and railstock mas pull throughapex safc 2

i thought at first that my mas was bad...but it still has a voltage readout and when i bypass my turbo(mas right into charge pipe just to test) it works just fine, so thats not the issue...im stumped has anyone else had any similar issues with the safc or have any idea what could be going on. i havent changed any wiring at all the only change recently was the setting (went from -27ish to -44..only running 6 pounds till its tuned) and the injectors. please help!!

check the connections with the wire where you welded them toghether.(for the harness)

definitely already did that, they are all just peachy the weird thing is, everything runs fine and had ran fine until i had the issue with the injector, maybe the afc is broken or something.

i also tried initializing the afc and reprogramming all of my settings but still the same. can an afc just stop working in that fashion? it doesnt seem like it would

horray i fixed it....the ground wires were backwards. brown before black.

seems odd that it would work for a while without it being right.
