Had a thought. As some of you may have seen, in the last 6 months the M5/M6 S63TU tuning scene has completely changed. This is due to the development of a Full JB4 + Boost control module from Terry @ Burger Motorsport Tuning. Basically, the flash only limitations limitations were similar to us, where there were absolute boost limitations, boost limitations by gear, etc. Flash tuned cars were maxing out in the 650-680 whp Range.

By leveraging the JB4 piggy back tuner and dedicated boost management controller, they now have the ability to fully control the waste gate function and run additive tuning to support the fueling or timing needs. This means they can boost close to 30 PSI. Cars with stock turbos, stock downpipes and exhaust and meth are making mid 700's now. Stage 1 billet wheel turbos in the 800's. Basically the holy grail of what we are after. A piggy back is a good solution since it intercepts the signals and can provide the factory ECM the signals it wants, and separately telling the systems controlling the hard parts ( IE Injector PWM and boost control systems ) to do something else

Now they needed to justify development due to the small market of potential for market of M5/6 that the S63TU motor comes in hence why it took a few years to get there. I am thinking the market for something similar for the AMG platform is way bigger since the M157 is in every model of car MB sells save for the C class. Additionally I am certain it would also support the M278 since its basically an M157 lite.

I am going to reach out to them and see what interest it may hold for them. They already have stage 1 piggy back tuners for the new 4 cyl and 6 Cyl turbo benz motors, so they are interested in expanding in this space and have some of the base system understanding it would seem. Would be good to know who would be committed to something like this right off the bat to get a sense of how many people would want to be part of a pilot group.

I might be completely off base, but since there are other M157 piggy backs available there must be a path forward on this.

Thoughts?

 

This is a great idea! Didn't know they did anything for the Mercedes platform. Competition is awesome for everyone

 

IN!!!!

 

That JB4 is so versatile... You can alter other function on the car it with too.

 

Let us know what they say.
Are you going to call them tomorrow?

 

definitely interested!!!!

 

 

Seem like a cool idea, as you mentioned the m5/m6 and even the v6 turbo tunning has blown up recently in the power they are producing...but it also has a drawback...what are the limits as this is all new to an extent.

My other issue is I have seen how they conduct business and it reminds me a lot of other tuners that have been on this board, that promise great things and talk the talk..only to later bolt out when it gets too sticky and the **** hits the fan

Are all these cars running fine? No limp mode? no codes? no parts going bust?

Alas advancement will only happen once someone pushes the boundaries, so all the best

 

Burger ecu products are on quite a few number of cars for quite a few years now. I doubt they have bolted.

That being said, what would really be the point of having a JB4? More options for stuff you can do? Race gas vs street fuel switch on the fly? Meth tune option? Because outside of that, the stock turbos are only blowing hot air and will not make much more power than they currently do due to size

 

The main point would be to be able to deliver more power in lower gears, and to be able to raise absolute boost. Other features like Meth tuning and multiple on the Fly maps, and ability to change settings and log through JB connect would be awesome too. Now on stock turbos, given the exhaust is a choke point, might not be big power gains up top, bu I have full hybrid turbos coming, and I'll need something to really run those things hard. 28-30PSI on an M157 with bigger turbos and meth would be easy high 800s.

 

Wouldn't mind having a JB4 controlling my ECU. I've followed numerous builds on N54,N55 and S63TU and these guys are who you have to go to in order to get crazy with power.

I doubt they can program our cars on the fly because our ECU's dont work that way necessarily. But, that doesnt mean they cant figure out how to get a piggyback working with a front-end and back-end flash to hopefully break up that ****ty "unwritable" TCU that holds back the power in these cars.

I'm all for Terry getting into the M157, M177, and M178 market.

 

The point of a piggy back is it intercepts and replaces the ECU. Multiple maps on a JB4 are different profiles stored in the JB4 and cna be swtiched on the fly because all you are doing is sending different output profile. Again, the key here is full waste gate and boost/fueling control based on torque request ( IE pedal position ). Now I am speculating on some of this, but still think this might be doable. will probably need somebody local to burger to pony up to be a test mule, unless we can convince them to buy a car once the M5 dev is done.

 

Well, sent an email to Terry, I'll see what he says.

 

I will support this with my M278 engine.


I was the first C400 to get stage 1 BMS piggy back, installed by Terry him self Dec 2014. I run E85 4 gallons per fill up and boost increased from 10lbs to about 14 lbs

Super nice guy and really involved with his products.

I tried for the 400/450 folks to jump on, but all I got was low take on a $300 product. I have stop posting on C205 forum since most of the post was negative towards Terry. I even posted on N54tech.com and got better response.

For those already tuned, adding the piggy back and adding some additional boost will make it worth it.

It done right with E85 or 100oct or Meth. JB4 is very powerful

I know my tune from OE is conservative and having ability to data log and custom adjust is the best piece of tech.

Terry will need a large take of owners to jump on to make it worthwhile. If a sub forum can do it, it will be this one.

 

 

I agree, its held the M157 platform back substantially. I'd love to run a bit of e85 or even have the ability to switch between mild and aggressive tunes at my leisure,... not to mention tossing USPS/UPS/Fedex substantial amounts of $$$ for overnight shipping :-/ I'll still keep mine, but I feel like it's already been overshadowed and tuners have moved on :-(

 

 

you can buy a extra ecu for $ 350-400 and have a race file done on it and just swap it when needed takes like 5 min to swap ecu or you can get HP tuners and flash your car with OBD II.

 

 

 

Yes I am sure 100% did it before with customer cars. Ecu needs to be shipped to them to Unlock the fee is $299.00
then you need 4 credits to flash your car with OBD2 you can also use HPTuner to log.

 

Woww I am surprised I am hearing about this in this thread! Just checked the HPtuners website to confirm and they do indeed support obd2 tuning after a one time pcm modification on biturbo cars. Pretty amazing in my opinion.

 

Just looking at them and yes it does say for the M157. That's really shocking, this could be an option. Kind of annoying to pay for credits but in the end. Might be worth it and cheaper to get a customer Dyno tune this way then.

 

This is great. So does this finally mean we can E tune these cars? do HP tuners do e tunes aswell?
