I could use more eyes on my attempt to tune the MAF.
Going from the K04 turbo to the ZFR 6758 Ilso replaced the LSJ intake manifold with the OTTP intake manifold and a small inline water to air that runs off the existing lsj intercooler setup.
I started by increasing fuel by 15% on the MAF table then made a easy short run with LTFT reset and LTFT STFT off through the VCM scanner functions. Made several adjustments to the maf curve and had to add a lot of fuel up higher where the K04 was not pushing boost at higher RPM.
what interesting is how nice idle looks with the STFT's off but the log afterwards where the STFT's are allowed to make changes the throttle has a small idle hunt loop. You can see the spark changing as it pulls fuel and lets it back in.
