I just got my WMI kit installed and I mounted it low enough that I could keep the cabin air filter.
I just need the WMI Firmware update and then ready to test, the tank is loaded with 50/50 mix and then I am ready to dyno.
Here are some pics of my install of the WMI

Between AMGMessiah and Vader, we should hopefully have some good dyno results soon.
Vader, I am selfishly hoping that you don’t muddle the dyno process with the methanol, or at least make sure you get clean JB4 vs base maps before turning that on, or else it will certainly skew the real world results for everyone just running JB4
oh well, all the more reason why a nicely done install video from BMS would be very helpful. Last I heard, they were working on that a few months ago!
It's easy to turn the tuning on and off and feel the difference or measure it via a dragy or track if you're so inclined too.

Gains are noticeable and our 1/4 mile runs are showing a 10mph gain trap speed, so that should speak volumes.

Other than that, are there any other goodies you can mention that you guys are working on or are testing, that can be integrated into future firmware? I suppose WMI counts as one, but things like exhaust valve control and other toys that the OBD2 and CANBUS connections let you play with?

From what we have seen map 2 is fine on 93 as well.
We're working on a few things actually. Terry would be able to tell you exactly what. I don't want to say anything I shouldn't especially prematurely. Don't want you guys to expect something, and we see that we're not able to do it in the end.
I'll tell you that the development will never stop and we're always looking for more innovative things to keep the platform moving forward.

My suggested dyno pulls:
1. JB4 off, Full stock with paper filters in comfort mode
2. Stock with Race mode
3. Stock with High Flow air filters in Race Mode
4. JB M1 with Boost Reduction by gear off for all JB4 pulls
5. JB4 M2 - I’ll this be worth it on 91 oct fuel ?
6. JB4 M8 “valet mode”
7. JB4 M7 WMI with settings at 5psi over stock, 60 sig scale and 9psi min boost
8. Could or should I bump it to 6 psi over stock for MAP 7? Or lower the min psi to 7 or 8?

Couple general suggestions.
Make sure you get comfortable with how to put the car into dyno mode. Sounds simple but God forbid the shop doesn’t know how to do it, the car won’t be able to complete the tests if the traction/safety/ABS systems are going bonkers.
You must be in the Odometer home dashboard screen, not the AMG screen or any of the others before doing it.
Practice this a few times while at home so it isn’t something you’re figuring out while the shop’s clock is running! https://mbworld.org/forums/c63-c63s-...tructions.html
You want 5th gear. That is 1:1 in our 7 speed.
You want the car is Manual trans setting otherwise it will kick down after you’re in 5th gear.
Let the shop know how many runs you plan on doing so they can schedule time accordingly. You’ll need a decent chunk of time for 8 runs with some changes in between.
The list looks great. #1-3 will be so nice to see, for everyone in the community.
Hopefully it’s worth doing #5 on 91 (map 2). Maybe BMS can confirm that you might just see limited additional power, and not that it’s dangerous to do?
Take lots of videos and pictures!
I may see about installing mine this weekend. I really wanted to wait and do the BMS intake at the same time but they are really delayed with no firm end in sight.

The codes were:
0300
0800
4833
E617
5CA3
0000
We shall see if it starts that way today.
I do have the BCM module installed, but not really sure how I utilize it.
