When i made a quite large change to the VE tables (which control fueling using the MAP and engine RPM) i left the MAF tables completely untouched, so theoretically speaking, the BLM figures for the cells in the VE table i changed shouldnt have been exactly the same, cause the MAF was still saying the exact same amount of air was flowing as before, BUT it didnt work that way, cause instead of my idle BLM figures being down around 110 to pegged at 108, they were now up to 117-114. The only thing i changed on that setup was the VE tables, and Datamaster was still saying almost identical air flow. The MAF does have a say in fueling control, but the big boss is still the MAP. The O2s also both apply correction within a limit. |
