Hey,

I'm new to RomRaider and i have a problem. I have m52tub28 and when i want to open MAF sensor scaling i just cant't, no map shows up. Here is a screenshot.

Thanks

The definition for the MAF Senor is wrong, it should be a 2D table and in your screen shot is appears to be a 3D table.
What definition are you using?

MS42 ECU Definitions v0.41.xml, I found it on here.

It works thank you. Just is it possible to see 16x16table, because 256x1 is somehow hard to see?

MAF is not a 3D map, it is strictly kg/h over volts, a 2D curve.
This is the only way to know which voltage step your are adjusting your MAF value for.
If you need to see its shape, copy the entire table and paste into a spreadsheet, then plot kg/h over volts.

I just saw the option to copy whole table. Thanks.. and i have another question i need to make MAF read values to 1100kg/h.. i heard about resistor hack... How do i wire 2.2kohm resistor, on which wires?

You'll need to search the BMW Tuning forums for that answer as I have little knowledge about tuning/modifying BMWs. I'm sure there's something over there about a 2048kg/h MAF modification that can be done.
