Default New JB4 Install, Log Check and question about maps - 11-17-2020, 07:23 PM

Excited to have my JB4 installed in my 2019 GLC63. Have only had a couple of chances to get on it, but it's already put a huge smile on my face. Vehicle is otherwise stock. Only Map 1 so far, as I believe I'm supposed to have my logs reviewed first. Not sure if I'm logging correctly so I've attached two. Please let me know if everything look okay.

Also, the original JB4 post for my engine shows the maps as follows:

Map Guide as of V2 Firmware:
Map 0: Stock operation, JB4 disabled
Map 1: Default performance map, 4psi peak over stock, taper to redline
Map 2: 5psi peak over stock, taper to redline
Map 3: 6psi peak over stock, less taper to redline, suggested for E85 mixture or octane booster
Map 4: 6.5psi peak boost request over stock, less taper to redline, requires unleaded racing fuel or E85 mixture
Map 5: 7psi peak request over stock, less taper to redline, requires unleaded racing fuel or E85 mixture
Map 6: Custom additive boost profile, boost request over stock
Map 7: Progressive WMI (water/meth) mapping based on boost additive setting and WMI flow
Map 8: Low boost VALET / Safety map

But the instructions I downloaded for my install show different maps (Map 4 is low boost "valet" mode. I don't want to break something by choosing the wrong map. Can someone confirm what the current maps are for the most recent firmware?

Finally, if the logs all look good, is there anything I need to do or not do before trying Map 2?

Map1 runs look fine to me! You should be fine going up to map2.
