What are you talking about? It has already done a 12.67 on Map 0. That is stated in the original post. Don't understand your "THAT" reference.
Something about your claims isn’t right. Either your satellite reading is very off or your dragy is broken. No chance that a car running mid 4s 0-60 is getting into 12’s. Share your dragy results via screenshot.

So, its not a claim. Produced similar results several times. You can actually check my build thread, or various other spots that I have posted the information, to include JB4 Whatsapp. Are you here to provide useful information, or instigate?

Payam, from Burger, thinks it could be $h!te gas. It is 98 RON, but I buy it from post. Really don't know who their vendor is, but it does make sense. AAFES isn't known for carrying quality stuff at the Shoppette. But it saves over $1.50 per liter. That can really add up. I am just going to bite the bullet and get some Super V Power 100 RON at the local Shell. Thats like 95 octane. You got to pay to play. It will probably take 2 fillings to get it totally 100 in the tank.
So, I installed my MST Intake, BMS Pedal Tuner, and filled up with 100 RON (95 Octane) fuel from Shell.
This morning (49 F) I did a couple a run with the most aggessive setting pedal tuner (shouldn't affect performance) on Map 2. The Map is on day 2 since I reset the ECU when I unplugged the battery to do the installs.
0-60-> 4.33
1/4-> 12.45
I have included dragy shots and the csv, so there is no questioning of my legitimacy. I am hoping the guys from BMS will be able to provide some feedback on what the next steps will be to optimize the JB4.

Not true. I did 0-60 in under 4.5 and 12.7@109mph. Draggy verified. 2 additional passengers in a GLC43.
JB1 map2. 2 runs. Both moreless same result.
Time also verified with another brand of GPS unit thats popular here in Taiwan.
So he absolutely can do mid 4's and mid-high 12's int he 1/4 mile.

Well, just looking at that log, I can tell you why your times are not really much improved: you have three big throttle closures early in the run. The first one looks like it's from a boost spike, but I can't see anything in the log that explains the other two. They are there in your earlier logs too. The ECU is closing the throttle because it's seeing something it doesn't like.
You indicated you had traction control turned off (or at least ESC). Can traction control and ESC be disabled on the C43? Maybe some portion of the traction control system is still in play and while you aren't feeling or hearing wheelspin, the system is detecting enough that it's closing the throttle to compensate. Or, there is the outside chance that the rotational speeds of the front and rear wheels are varying enough in the lower gears that it's closing the throttle to balance it out.
The other cause for throttle closure with this Bosch ECU is overboost, but again, I only see it once, in your most recent log for the first closure, but not the second or third. Maybe dial back the boost in the lower gears with the boost-by-gear setting (if that's on this version of the JB4).
What's odd, is that I don't think I've heard anyone else with the C43 and a JB4 have throttle closure issues come up.
As I said previously the JB4 is a tuning tool that you can use to add as much or as little additional boost/power as you want. It's easy to imagine unique situations where cars won't pickup power with additional boost. Fortunately the JB4 also includes advanced logging tools to evaluate your runs and a tuning interface to let you adjust boost by RPM as needed to maximize potential gains.
I'll check out the map0 vs map2 logs to see what the difference is.
Ideally for analysis you'd do a map0 log, record on JB4 and dragy record it same run (so we see trap speed), then same for map1, and map2, so we can compare trap speed vs. boost vs. ignition advance and figure out why trap speed isn't going up.
So, I did a Map 0 run. I got it...its only on the first day...but it did hit close to OEM advertised 16PSI boost. it would probably get better as next week goes by. I will run a Dragy then. I have attached the graph from one run and the .csv from another. Why? Becasuse the oneothers I emailed to myself didn't make it to me in work, and I work in an environment that doesn't allow cell phones for security reasons.

Comparing map0 vs. map2 I see map2 is making 3-4psi more, timing is similar, fueling in check. No signs of knock or obvious issue. Trap speed should be 3-4mph higher here?

Bothe maps 1 and 2 appear to only be able to hit 18 peak. The 19s should see about 20 for 1 and 22 for 2 based of of previous models. Map 0 confirms that they are making around 16 from the factory...

Like I said, the current JB4 firmware needs to be updated with the proper scaling for 2019 C43.
I have posted my logs here, on the C43 JB4 WHAT'S app , and emailed BMS. Folks on the What's App made it clear that there hasn't been a lot of work done in the C43 JB in a while.There needs to be a serious look at the 19s.

The BMS crew is supposed to be working on a firmware update for the 19s. More to follow. On another note, BMS has released a Wastegate Control Module for the C43s. Link below.
