I have been trying to get this to work correctly for over a year. I have the Inglese 8 stack on a 289 HO SBF. It ran much better on the old Weber carbs so I know that it's not a mechanical or ignition issue. The problem I'm having is that it's pig rich at low loads no matter what I do. I talked to Brian at FAST and he gave me some ideas on "tilting" the fuel map so it will run leaner at low load by running a different fuel pressure than actual. This got me slightly closer but I can't get a hold of him again (other FAST operators hung up on me when I asked for his extension). The ecu is trying to trim the fuel -25% everywhere except idle where the active learning kicks in does fine. The AL rarely come on anywhere else in load or rpm. If I slowly rev it in neutral the AFRs drop into the 10s and 11s off idle. Cruising AFRs are in the 11s. Are there other ways I can trick the ecu to get the rough shape of the basemap to work with this engine? Displacement size maybe? Right now it's set to 39/lb injectors (which are in it) and 45psi fuel pressure (35 actual) and this got it closer but still -25% trim all over. If I put 50psi in the tune it goes too lean at high load.
