Title: Fueling not matching requested
Post by: savages4 on July 14, 2013, 11:52:21 PM
Just got my wideband, fuel pump etc in and I'm trying to dial in my fueling finally.  I was curious what maps you would suggest correcting to get the fueling to follow requested more.  I'm using an RS4 MAF and bosch rs4 maf sensor and I have copied over MLOFS, KFKHM, and MLHFM from K-box rs4 bin.  Also, is it safe to copy KFLF and KFLF axis's from the k-box file, I haven't done this yet but thinking of trying it to see if it helps however after looking at the values they are higher which would seem to throw it even richer which isn't what I need.

Thats actually pretty close.

Just pull a bit through KFLF or KFKHM.

Also, log ps_w to make sure you aren't at its limit.

So when adjusting it a bit through KHKFM should I do the entire load range or just the high load parts?

I'd stick to load areas you have logged.

That said, you should attempt to keep it relatively smooth.

No issues using the k box axes but don't go beyond the K-box upper load line of 191.25.

Adjusted KFKHFM and looks like I got it pretty dialed, just need to get desired leaned up a bit over 4500 rpm..

Awesome! nice work.

btw.. thats pretty rich... might want to consider not going any richer than 11.5 ...

I concur. My car usually starts bogging down at anything richer than 10.8, but that's with 2 x 630cc of W/M so it would probably go down a bit more on pure gas.
