Title: MLHFM, MLOFS help desired Post by: Ckorsch 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 Title: Re: MLHFM, MLOFS help desired Post by: Ckorsch on March 15, 2021, 06:39:46 PM 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) Title: Re: MLHFM, MLOFS help desired Post by: Tomas on March 15, 2021, 07:07:47 PM There's a euro M bin file knocking around somewhere in this forum that works with the Bosch MAF instead of Hitachi.

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. Title: Re: MLHFM, MLOFS help desired Post by: tao13 on March 26, 2021, 10:22:07 AM Stock case what diameter has ?
