Also any plans for a JB for the C63?

Is there a metal enclosure available for this JB4? I thought I remember seeing it somewhere on the BMS website, but I can't find it now.

That specifically mentions E/F series BMW. Will this W205 MB JB4 fit perfectly in that case? Thanks,

Here are a few quick logs from last week on my C43. Seems like I don't make map 2 target boost of 6 psi until 4th gear? What all should I be looking for when making adjustments on my map 6? I'm sure the Texas heat isn't helping, but our platform seems to be very sensitive to IAT. DA varied between 2200 and 2900 during these logs.

Post the CSV files for logs, so I can open and view them in the JB4 interface. But the target is a request. The turbos may not be able to hit that request until EGT gets up which is what you are probably seeing.

Here is two logs with a map6 in my c400

Both logs starting in 2nd Gear DA around 2600

First log 93 Degrees outside with 93 fuel
Second log 95 Degrees outside with E30

Doing this from my phone so hopefully I got the logs to upload correctly.

Both look really clean to me. Timing rolling up towards redline, boost on target, AFR in check.

My bad! All runs on E25. How does EGT effect our cars?

In lots of ways, but what I was referring too above is when you're working against limits of the turbo itself, as EGT goes up there is more relative exhaust pressure to hit higher boost targets.

What's wrong with the "throttle fail" log?

Using boost by speed I see, looks fine to me!

I was under the impression that big drops in throttle indicated that I was requesting too much boost. Are large dips in the throttle ok? Is there a better method to adjusting target boost in map 6?

Will this work with the GLC43 AMG? I assume so since it is the same exact engine as the C43.

Throttle is used to regulate boost if it jumps over target or the target suddenly changes. Dips are fine. If the throttle is consistently closed that would indicate a physical issue with the car that needs to be resolved like a stuck wastegate.

Hey Terry,

I am hoping you can tell me your thoughts on running JB1 on Map 2 on 91 octane at 5K+ ft altitude. I have researched the octane at altitude topic but there seems to be much debate. The idea is that 91 octane at high altitude performs the same as 93 would at sea level but that seems to be for NA cars and not turbo cars. I really would like to run map 2 but we only have 91 octane fuel in CO. If the answer is to run some logs on map 2 and evaluate, what should I be looking for in the logs that would indicate the car is behaving badly? Thanks for the help!

I'd have to see the JB4 log to evaluate it myself. Mainly looking at the ignition advance profile during longer single gear pulls, and shortly after shifts, for 3 degree drops indicating pull back.

Thanks. I was hoping maybe the question had been asked before. Looks like I will have to upgrade to the JB4 so I can get a better log to evaluate

I remember for the E9x, one could simply clear the ECU and remove any data about max boost pressure and the dealer would see no evidence of the tune having been installed. Is that still the case with these newer cars? I have heard rumors of peak boost being permanently recorded, but I imagine that is just speculation.

The JB4 prevents the ECU from ever seeing true peak boost.
