try using kfkhfm to tweak idle and part throttle fuel trims.
make sure mlhfm for your maf sensor is scaled to the proper housing size.
set krkte to allow proper wot fueling and tweak kfkhfm for fuel trims, this is the best method i've found.
jude: what equation do you use to scale the stock mlhfm? i've seen alot of uncertainty on this matter...
sorry i missed this question earlier.
i take the (new diameter)/ (old diameter) to get my correction factor and then i multiply mlhfm by that factor as a starting point.
I have had to make very large adjustments to the scaling in some cases, especially when using a bosch maf. sometimes scaling seperate parts of the map up and down accordingly.
