	Copy MLHFM from RS4 bin to 1.8t bin ? « on: March 22, 2017, 02:41:44 PM »

Hey Guys

Just a short simple question.

Can I just copy the data from a RS4 mlhfm map and paste it into my 1.8t bin file?
Will it work ?
I mounted a bigger turbo into my wideband converted S3 (1999)

Or do I have to manually scale my old stock mlhfm map ?

Thanks in advance

Did you install a complete rs4 maf? If so, yes.

Don't forget MLOFS if applicable

Both (my stock and rs4 maf) are Bosch.
So i guess MLOFS is 200 in both files ?

In my 1.8t file it is already 200

I'm asking, because my axis looks like this:
(already pasted RS4 values)

That axis is incorrect. try 8 bit 1,2,3 data with factor 0.009765625
* data is also not right! My definition shows 16 bit lo/hi values with factor 0,1.
should look something like this:

I'm actually about to do the same thing but on a wideband converted audi TT (2001), using RS4 MAF and GTX3071R.
What turbo are you planning on running? Have you thought about the ps_w limit?
My plan is to copy the MLHFM map and increase boost slowly while watching ps_w. Might need to underscale KFKHFM and compensate with KFLF.

Or do 5120 hack and have tons of headroom! Even on stock map sensor this is really helpfull. But I can imagine GTX turbo wants to run at pressures over 1.5 bar too...

I would love to do that but when I briefly looked into it, I saw that ASM changes are needed so I assumed it is near impossible for a noob like me.
Maybe I will give it another look.
Any idea if someone has already done it for 8N0906018H or similar?
