	MLHFM, MLOFS help desired « on: March 15, 2021, 05:47:21 PM »

I think I'm in the right place for this question "Noob Section".

I'm attempting to tune an originally AL-Box ecu (I no longer have the stock file.). It now has M-Box.bin loaded onto it and I'm trying to make the proper adjustments for the Bosch vs. Hitachi MAF's, at the same time, a larger MAF housing.

What I've read so far:
Set MLOFS to 200 (the M box .bin has this set at 0.)
Scale MLHFM by 35.5% to account for a 85mm MAF housing.

I've done this and yielded poor results. Before you say "read the wiki" I have, and about 20 related forum posts. I'm not sure what I don't understand.

Please advise

-Calvin

I'm using files attached.

Obviously you can see the stock .bin I started with. Then the one titled "ScottMAFCS.bin" is the one I made the changes to. (Scott is a friend, not a customer fyi)

There's a euro M bin file knocking around somewhere in this forum that works with the Bosch MAF instead of Hitachi.

I got this all sorted out. Delete if wanted.

I just needed to source a Bosch ori .bin and a xdf that would read it. Copy the MLHFM and paste it into the generic M-box .bin that floats around these threads.
