idle looks very rich (I cant download the msq its disappeared)
Also CLT is 63F but warmup is off and that seems unusual. I think you need to lean off the idle area a little and smooth it with no big leaps of either timing or mixture around the idle area of the 3d tuning maps. It also looks like you are using EGO correction at idle and it has a very wide range of correction. I suggest you make ego apply only above 1500RPM then manually tune the idle mixture. I would guess that the fuel your VE table is indicating for idle is very different from that required for the AF ratio table and EGO is going mad trying to correct it.

thanks, will try to tune the VE table instead of EGO correction.
the CLT is C, not F.
