	16487 - Mass Air Flow Sensor (G70): Signal too High « on: January 30, 2012, 02:35:36 PM »

I had this code after today. Any idea what would cause this or what to do to fix it? The TC light and ABS lights came on during a pull as well.

RS4 MAF using stock RS4 MAF scaling.

Thanks!
Nick

Thanks guys! I just used the KFMLDMX and KFMLDMN values fromt the RS4 file. I'll do a few runs and see if it took care of this issue.

set your entire KFKHFM table to 1.00 as well like in the RS4 file...

Hi all.
I have the same problem but i saw it is activated only on 4 or 5 gear at highet speed and rpm.
I have the stock MAF from BAm engine and the file is stock from BAM.
I attached my stock KFMLDMX and KFKHFM.
Is it a good option to make HFM all 1 like you said fee post ago or increase KFMLDMX?
I think HFM will modify the partial adaption too, Correct?
And other question , my load is higher than Load axis of HFM, do you think i must increase lastr value of axis too?
Many thanks in advance
