RomRaider

I am attempting to scale a new MAF in romraider. I set the reading at the lower volt and the max reading at the highest volt. I highlighted all the values between low and high and clicked interpolate and it turned all the values to zero.

What am I doing wrong?

Or...what is the actual procedure to scale the MAF in Rom Raider?

Thanks in advance!

Its on a BMW MS43 ECU (dont think it matters).

you mean you selected the contents of the whole MAF table in romraider and tried to interpolate it?

If I recall that will perform a linear interpolation which is not what you want for the MAF curve.
Typically you would measure AFR error for each voltage cell and apply an error correction to each AF value. You'll need a WBO2 installed for this process and it's easiest to complete while running in open loop mode.

Jon....yes, guess it was wishfull thinking to be that simple.

Soooo I have to data log it...

I cant just input the known voltage/kg into the map?

Why wouldnt I just adjust the fueling to the new maf opposed to trying to adjust the MAF?

yes you need make data logs of the final fuel base (the target AFR) along with the MAFv(voltage) and your wideband o2. Once you've got enough log data then start looking at the difference between the final fuel base and what your wideband is telling you.

For example, say at 3.5 volts your fuel target was 11:1 AFR. But your wideband tells you 10.5:1. Then at 3.5 volts in the MAF scale the corresponding g/s value is too high. Reduce the g/s value at that voltage and re-test until your wideband is matching up with the fuel table.

can`t find the on off for 2048 maf just the scaling map and do rom raider does the checksums
