I’m honestly not sure, I’ve seen that too from other logs I’ve looked at in here. Maybe I have a old firmware on my jb4 I don’t know if they made a updated version I only see one hex file on n54 tech for the firmware for my ewg. If anyone would like to chime in on this please do!

I’m rwd, and ok I’ll adjust the weight to that. Also just wondering is their anything detrimental to my car in the logs I posted, I know I’m not quite hitting target boost but I’m going to guess that’s From having a stock intercooler, inlet pipe, charge pipe etc.

That's my bad on the weight, totally forgot RWD F30's existed

It looks like you're hitting boost targets well enough. In my experience, it's rare to constantly be exactly at target boost all the time.

What you said about your WGDC and the fact you may have old firmware could be contributing to the fact that we're getting what are effectively unrealistic numbers on VD. Because the VD results hinge completely on the accuracy of logs, it'll be impossible to get accurate numbers with said logs. Like you said in the original post everything has to be spot on for it to work. It's absolutely not a strike against you, I'm just pointing out for discussion's sake.

Yeah, I'm mainly curious about WGDC here. If you're maxing it out at 100% during the pull, it's going to stress that turbo a lot. The only concerning thing I saw was knock in one of your logs. You dropped from 13.5 to 8 degrees of timing up top, which indicates knock.

Regarding the logs, another thing that's odd is the timing. I understand JB4 is running off an internal clock and the polling rate seems quite slow, which I'd be interested to see how that could change a dyno as well. Another thing is the curve of the dyno. While I understand you changed your map to try to get more power top-end, but there is a physical limitation of the turbo there and if anything, it's being thrown out of its efficiency range to make up for the lack of flow at higher RPMs.
