Default Q60 3.0t Data Logging Help - Yesterday, 06:20 AM

Hey everyone, I just received my JB4 yesterday and have been messing around with the different maps and map 6 specifically. However I'm having this weird issue regarding my AFR and Ignition timing. It seems whatever map I run (even map 0) the AFR and timing seem fine at idle, but after going WOT and letting off the throttle, both gauges max out and the graph looks very concerning. I don't see why it would be doing this on map 0 though, any thoughts? Ill post a few different logs soon.

My only current mods are:

HKS Resonated Lower *********
CZP CBE

Me being totally new to JB4 and all, for all I know this could be entirely normal. Would appreciate it if someone could check out the logs I posted in my reply below to let me know if this all seems normal enough!

Any help appreciated!

Not sure what looks concerning to you. The AFR after a pull on decel will go full lean since the ECU is cutting off fuel injection. This is normal.

Yeah after thinking about it a bit I realized this as well. Other than that though, how does my map 6 look i terms of AFR and timing?

Its always tough to tell from a pic. You didn't go to redline so I cant tell if you tapered the boost curve or not, but you should above 5000 as the turbos start running out of breath. Otherwise looked pretty good.

Yeah I just did a quick run and wasn't able to get to redline, but I do taper boost off after like 5500.

Thanks!

For logs attach the CSV directly to the post so I can open it in the windows JB4 interface to view.
