Did anyone try installing it to a Q50 2.0T? It shares the same M274 engine with W205

Hi, new member here. I just installed BMS JB1 on my C43 and would like to share my results.

Instillation was very easy, 3 plugs, route the wires, secure/ziptie and done.

My track times before


Times with BMS base map


All runs were done on 93 pump gas. Using online calculators to figure out HP gains, from averaging all my E.T.s and trap speeds. Stock, the car is averaging 367hp, which is on target with factory rating. Using the same method for the JB1 I got an average of 413hp. That's a solid 46hp gain.

Not bad at all! Thanks for testing it out!

Map 0 - stock C43 map, boost peaked to 11psi and tapered down to 9psi.

Map 1- It's the standard default map that BMS unit comes with, it's ideal for 91 octane. In this map boost peaked to 14psi and tapered down to 11.5psi

Map 2- It's for 93 octane and higher. Boost peaked to 15.7psi and tapered down to 13.5psi

My previous 12.5sec runs were in map 1, today I switched to map 2 for the 12.35@112.98




On the way to the track:
After almost an hour ride to the track in map2 without any problems and a couple of miles before getting there, I decided to practice my launch. Also, to make sure I won't get "limp" surprises, well, it surprised me :D

My son was driving behind me recording.

Results look great! That is default settings I presume? You can also raise boost on Stage1.

Firmware is the same. We've not released any C300/C400/C450 firmware updates.

Do you mean switching to map2 or using the usb cable to increase boost by rpm using the data logger?

You can switch to map2, or even use map6 to create a custom boost additive profile.

What are the default values that BMS sets for map2 ?
what is the boost safety set at, map2?
what are the boost settings for map 2?
1500 ?
2000 ?
2500 ?
3000 ?
3500 ?
4000 ?
4500 ?
5000 ?
5500 ?
6000 ?
6500 ?
7000 ???

The reason I'm asking is because I want to start adjustments with map6 and would like to get 1 or 2 more psi than map2. When I open map 6 "User Adjustments" all I see is "Boost Safety" set to "3".... is this 3 psi or 3 over stock. ?

In map6, assuming stock boost is 10psi and I want boost target of 16psi, do I set the "Boost Safety" to 16 or 6?

Also, when setting "RPM/MAP 6 Boost" for 16psi, do I enter the target boost, or target boost above stock?

For example:
RPM MAP 6 Boost
1500 11 or 1
2000 12 or 2
2500 13 or 3
3000 14 or 4
3500 15 or 5
4000 16 or 6
4500 16 or 6
5000 16 or 6
5500 15 or 5
6000 14.5 or 4.5
6500 14 or 4
7000 13.5 or 3.5

Thanks

You can record a map2 log, and then look at "target", to see what that boost targets are. If you need addl help just email us with a log and we can work on it!

Can you please answer my other questions, thanks

Q1 - In map6, assuming stock boost is 10psi and I want boost target of 16psi, do I set the "Boost Safety" to 16 or 6?

Q2 - Also, when setting "RPM/MAP 6 Boost" for 16psi, do I enter the target boost, or target boost above stock?

For example:
RPM MAP 6 Boost
1500 11 or 1
2000 12 or 2
2500 13 or 3
3000 14 or 4
3500 15 or 5
4000 16 or 6
4500 16 or 6
5000 16 or 6
5500 15 or 5
6000 14.5 or 4.5
6500 14 or 4
7000 13.5 or 3.5

"Boost safety" is not used on your tuner. Doesn't matter what you set it to. 20psi is fine.

For map6 you enter "boost over stock"... So, 5.0 for 5psi over stock requested.

I have been running map 2 and e30 blend for 3 years on stage 1. Lease almost over and currently running map 3, setting 6 over stock and dwp at 30.

Runs strong....

I only wishes map 2 was set to about 5 over psi since i feel the advance timing helps with throttle response.

Map 3 as described above feels slightly less responsive but playing with the dwp settings help out, simailar to the VQ engine.

Likely i will end up w another MB with the same engine.. so i do plan to keep the tuner and experimenting with ecu flash and bms tuner.

For boost evaluation I'd have to see some logs. But we can always tweaks those maps.

Besides MAP BOOST, what else works, does FUEL BIAS, FUEL OPEN LOOP, MAX BOOST 1st work?

Basically, what works and what's not used? Thanks

Open loop can be used to range fuel trims, if needed. Stage1 has no CANbus data so the other options are not active.

I tried MAP 6 adding another 1psi over map2 and better fuel mix, but the car didn't like it. Both (ECU boost request) and (timing) in map 6 were less than map 2.
While I'm asking for more boost in map 6, I think the car is pulling timing, causing the ECU to request less boost, thus giving me less overall boost than map 2.

Terry,

Jumping from the M4 into a 2018 AMG c63S. Will this tune work on that car, if not, is there anything in the works? Thanks-

The nissan vq stage 1 has map 2 with 5 psi. We have 3.

All we need is an update or terry to unlock map 2 to allow users to adjust at their own risk.

I use map 3 with boost safety at 6. When i save, it holds that value.

It provides a good bump in power with 30-second installation. I just sold my car so mine is up for grab. PM me if you interested.
