    Voltage data for stock AFM M20B25

    Does any body have a voltage/rpm table handy? I'm going to modify the signal from an MAF from an e36 328i to match the AFM's in order to complete the swap.

    Already tried to obtain this data the same way you are. The only person I could find that had it had lost it.

    Ely (rs4pro3) may eventually have the voltage data for the eta engine but basically you will need a SMT6 or similar piggy back to monitor the data.

        Do you mean the MAF? My AFM was over 1v at idle. Very strange....

        Look for my writeup, its VERY easy to figure out a basemap to get the car working. Unless someone has spent an hour on the dyno tuning all the cells with a wideband, there isn't really a right answer yet.

            what about just plotting it throughout the rev range to get a basic curve?
