Hi, 551R on an 03 Allroad tip.

I'm having trouble getting AFR to do what I want.  I tried putting .80 on the last 2 columns of LAMFA, which didn't seem to affect AFR at all.

I then scaled LAMFA (stock file was .5 .6 .7 .8 .9 100) tried both (0.5 0.6 0.7 0.8 0.9 1.0) and (50 60 70 80 90 100) neither of these seemed to change things either.

Could I please get some words of wisdom on what can be done to get my fueling under control?  Also for looking at the logs am I best to look at (Fueling>AFRDesired, LamdaControl, LamdaPartProtection), or other?

Thanks so much in advance!  Smiley

Log will be attached in separate post as I've tried posting it here TWICE and had to retype this :/

How did you go about scaling LAMFA?

For LAMFA, look at Driver Requested AFR

Thanks Guys! 

Scaling was by creating a 'LAMFA Scale' XDF parameter in tunerpro and setting its Rows definition to be the same as the LAMFA's Columns definition.  This was based off the 551M's method (at a different address) because my XDF did not come with LAMFA scale as a defined parameter.

Thanks, it looks like I wasn't even logging "Driver Requested AFR" lamfa_w.  I turned it on in my definition thank you so much! Smiley  Is there a different AFR I should be logging to view what the Final AFR is, regardless of what map it's looking at at the moment?
