The fuel side of the air/fuel mixture is manipulated next. Through the Base VE table, Brian adds and subtracts fuel based on closed-loop O2 sensor readings. With the engine held at 3,000 rpm, and then moving the throttle from light throttle to WOT, we were able to see how far air/fuel was from our target. Fixing the fuel curve is done by changing the value in each cell by the O2 correction-percentage amount, first in the Target Air/Fuel table and then in the Base VE table, until total correction is less than 5 percent.
