The factor for the map values themselves may be 0.021195 as suggested in the A2L, but given how much the rest of it. 40 MPH = approximately 1.70 volt. 60 MPH = approximately 2.10 volt. Check the resistance of the MAF signal wiring. Pin D on the MAF and pin 50 on the computer (dark blue/orange wire) should be less than 2 ohms. Pin C on the MAF and pin 9 on the computer (tan/light blue wire) should be less than 2 ohms. There should be a minimum of 10K ohms. The MAF tab relies on the stock closed loop system and works solely off of the short and long term fuel corrections in the ECU. That means that any problems with the stock closed loop logic (delays, over corrections due to large injectors, etc.) will plague the results of the MAF tab in RomRaider. I do my MAF scaling in open loop. MS45 to MS43 ECU Conversion. If your car is a 2001-2002 330i/330ci, this page will not apply to you.
