My Boost Leak Log... Big Leak Plugged, seek feedback
After tightening the coupler to the throttle body yesterday, I went WOT last night for a couple seconds, and hit a little over 17 PSI, whereas I only holding 5 PSI before that. The pipes aren't lined up properly, and I can see coupler that is buckled a bit that may be leaking air. Despite this, I wanted to try one datalog to see what it looked like. I kinda pussy-footed dipping into WOT, and shifted really slow. I'm not familiar with the sound of the HKS bpv (set to recric), and I didn't want to blow a coupler off, lol. So, I think I still may be losing boost, although the boost was pretty stable. I maxed out at like 17.5 PSI, whereas before I had seen it peak at like 19-20 for a single row. I only drove long enough today to fully bring her to temp. Good new is my BATs are nice and chilly, fuel pressure is excellent, and no KR in sight . AFRs are a little rich and whacky, which suggests that boost leak(s) persist. They will be fixed on Thursday.
I was surprised my WGD% didn't increase to try to make more boost to hit the load targets? Unless I was already hitting them at a lower PSI because of the fmic? My calc load was pretty high.. hitting about 208 and 210 pre and post shift, respectively. I dug up a WOT log I took a couple weeks before the fmic went in and attached it for comparison. Couple things here... First, with the FMIC and potential boost leak(s), my boost is a lot more stable than it was before. Also, the calc load is higher with the fmic with slightly less boost. My prior maps had me hitting higher boost, but the calc load was the same as with the fmic... if anything the calc loads were lower before. Am I correct in thinking that the fmic increased VE, and as a result I'm achieving higher calc loads with less PSI? If the logs remain similar after the leaks are fixed, can I safely increase my load/gear targets? I think I will use the +fmic map first, to see how the increased timing & slightly leaner OL/WOT fuel targets affect calc load first, before I start tweaking (and to control for variables).
ALSO, I am not yet running the +fmic map. This map has the identical load/gear tables as the +fmic, but not the advanced timing and not the slightly leaner OL/WOT AFRs. So, for the two logs below used that same map (including the same MAF calibration too). This map I was using before, that had my LTFT's within 2.
Please look at the two attached logs.. pre & post fmic. I'd appreciate your insights/comments/suggestions. Thanks guys!
