So my engine returns for the 2nd time LOL, tomorrow and i know how to dial in idle and cruise i think. Ive watched the videos a thousand times LOL. My question is, do i use the mafcomp sliders to make boostest and actual boost match up when im doing wot pulls? I cant seem to find a video on ecmtuning that explains that.
Also, if my afrest and actual dont line up what can i do about that?
 
Zero out your mafcomp, and add more fuel globally , but then you will need to re-tune your idle and cruise. Once the AFR and Widband are similar at WOT then you can target your AFR in the DA tables, then tweek/calibrate airflow if there is still any minor deviation between AFR and wideband.
 
Ok, i just looked throught the knowledge base on their site and came up with a couple answers. Im sure boostest is a mafcomp adjustment, but like you said, if the afrs are off then ill have to adjust global and retune idle and cruise and do a new mafcomp. I think itll be pretty easy now that ive read a bit more. Ive loaded evo8 mod 1 tables to get a much better starting point too.
