Hello,

I would like to convert an AFM to MAF on a Bmw E30 325i (DME 0261200173), many companies offer kits, but the goal is to understand the operation.

So for the connections it's not a problem, but after that you have to modify the cartho.

So my question

Following the passage in maf, it will be necessary to modify the maps AFM or all the maps of the DME.

If you have any information ?

maf signal is kg/h

old potenciometer flap signal (m3/h ?) and air temp = maf

you must mod afm calibration and remove air temp corection from that...
