help with mass air meter conversion bmw-nissan

[speedsex]

I have a 90 bmw 525i m20 engine with a 173 dme, and i would like to convert the mass air meter to a nissan 300zx z32 . both sensors are bosch and both 0-5 volt. both have xdf files and you can find bins online.

I was thinking i could just move the maf scaler from one bin to the other.
but the scalers are not the same chart values

Or run the new maf inline with the stock bin and record voltage. but i have no way to datalog this info



any info on this would help

thank you
