IMO the first thing to do is get your wideband logging into Efilive. If you have the V2 unit the best way is to get a serial cable from TAquickness. If you have the V1 you will need to go from the EXT.ADx analog ports with the supplied cable(if they ship one with the lm-2). Once this is done you will need to ensure that your IFR table is correct for your injectors & rail pressure & then go through the AutoVE & Automaf procedures.
Fuel supply definately seems to be a problem so you will need to check that out as well. Logging fuel pressure is a good way but it costs a few dollars to set up.
