Next, disable Cylair Anticipation, Cylair Filter, MAF Adapation, Long-Term Fuel trims and max out the Closed Loop 02 Sensor temperature so you will be tuning in open loop in order for you to dial in your MAF. Next, you'll need to get the proper values for your injectors. I recommend that you look on the injectors for a part number and Google it so you make sure you have the correct values. Next, set the Cylair WOT Multiplier and Cylair Max Multiplier to 1.99 and Max Load to 2.00 or higher, depending on how much boost your running. Now your car will be ready to tune. I would set up a histogram with the MAF Airflow vs. Voltage table with your wideband set as the input for the cells. Then set your Base Fuel table to 1 Lambda across the board and start logging. Make adjustments to your MAF and keep going. It should be a nice smooth curve. Do not go WOT or build too much boost as the car is set to run at 1 Lambda and will be too lean. This is just to get the first part of the MAF transfer accurate. I would start there.
