Mods are still Jb4 and DCI only.
I'm on 50/50 (e85/93) so I'm going to give map 7 a try just for poops and chuckles.
Will post logs sometime this week.

Map 1 (93 octane) vs Map 5 (50/50 - e85/93)
All logs done on same road for consistency.
A few more mods then I'll put this car on a REAL dyno.

You're underboosting a bit and the timing curve isn't as awesome as it could be, but all in all looks OK. I only looked at the first log.

Everything looks nice but you’re very tight on fuel trim up top. Add in some scalar perhaps?

I thought the JB4 has a different scale than COBB. where by 50 is where you max it out. This is what I remember at least.

I know on COBB it's +/- 34.

You could be 100% correct, I won’t pretend to know native JB scaling.
