i have the same exact issue, my car runs fine but i get code 1211 and im running red label 413 ecu with s50 24# 3.5maf tune on my s50 swapped e30, no vacuum leaks, new coils, new spark plugs, new 24# injectors, new 3.5 maf, idles perfect and pulls strong i just hate the CEL staring me in the face, any fix yet? the tune im running is unchanged from the one in the download dropbox.
