Thanks... I've put in an inquiry with my local MB dealer to see what kind of pricing I can get on the car. I prefer to own at least one of each car we develop a tune for to do proper durability & drivability testing, etc. With engineering time it's easily a 100-200k investment. Based on that I have to consider how many tunes we might sell to determine if the project is viable.

Since the same engine may be used in a few platforms that bodes well. And it seems at first inspection that the C300 and C400 share the same electronics which means a tune developed for the C400 could be adapted to the C300 with revised software. Also a good thing. The last thing I'd want to know is what's going on with the C450 and whether RWD models will become available.

this forum does not use E85 much.. even tuned Turbo cars.

Adding 1 or 2 gallons of E85 during a fill up of 91 oct? is there a benefit to a Turbo stock ECU? Does a car need to be tuned for E85 to use it.

Or should we just add 1 or 2 gallons of 100oct for some extra power.

Your knowledge on this topic would be appreciated.

Jon@BMS

I'll be sure to do some testing if/when we source a car and share the results.

Starting to wonder if getting a C300 might be a better idea as a starting point. I hear they expect it to outsell the C400 5:1. Our BMW 328i tuning is very popular due to the volume of cars out there!

How and where can I get this? I live in Japan and will be getting my C200 delivered in January. (No C300 or C400 for us.)

MFRace

C300 will definitely outsell C400 by 5:1 or more. However those that chose to spend more than $5k for more HP/Torque already are probably 10x more likely to buy a tune for additional HP. In my opinion I'd go for the Halo product first with the C400 and follow up with the C300 later.

I am admittedly biased as I'm taking delivery of my C400 later this week, and would buy your product immediately if it was available.

TopGun32

i'm in the same boat.. i'm a few months from getting C400 or sticking to E550 sedan.

a mild tune that takes advantage of E85 mix.. should yield good results.

E85 much easier to find and cheaper than 100 oct race gas.

Jon@BMS

That is a fair point. And the C400 would be a lot more fun of a test car to have around, personally speaking.

I'm poking at my local MB dealership for a good price on a stripper C400. We'll see where it leads. Part of me wants to wait for a RWD just because it will be easier to dyno (our normal dyno can't do AWD cars) but on the other hand AWD might be more fun from stop light to stop light with brake torque launches.

Jon@BMS

After some poking it's difficult to get a low optioned C400. While they are all super over-stocked on various C300s. I think I'll just grab a base C300 for ~$36k to get started with development. I hear they run high 14s stock. If we can get them in the low 14s I'll be happy with it. Then when the C450 comes out I'll just grab one of those. Hopefully by then they offer RWD only.

On the C400 front if anyone close to zipcode 93065 has a C400 and is interested in tuning some day I'd love for you to swing by so I can pop the hood and do a little non-invasive data collecting. Easy things measuring the boost pressure via the OBDII, and taking photos of the various DME connectors. Just email me at terry@burgertuning.com.

mechatune

i love how this turned into a C300 tune thread. i'm part of the 5:1 majority

Jon@BMS

lol I know. I'll make a new thread shortly as C300 tune development has begun.

I would be very interested in a C400 tune.. I'm just waiting for my darn car to get in

c4004matic

Copied from another thread:
Not to diss anyone but I'd avoid "tunes". The manufacturer spends 10's of millions of dollars employing 100's of engineers to provide a car that gets the best combination of power, fuel economy, emissions and most important longevity. Engine "tunes" always screw up a variety of these parameter if not all of them, in general mostly producing over boosted conditions that wreck havoc with everything else. More often than not the biggest change is a motor that is constantly operating the wastegate due to over boost for marginal improvements in performance. IF you want a car for the track and don't care about anything else by all means feel free to "tune" it.
Anyone else should avoid them like the plague.

gdmmercy

I spoke with Renntech and they said they are currently in the development phase of the tune for the C400. The guy said he will fallow up with me in the Spring to let me know when will be available.

BoboPolo12

This is a good point and is worth mentioning because there's always a risk with tuning. I do believe that some tunes (or map settings?) are more aggressive than others though. I also think that some engines can safely handle more power via tuning but the manufacturer may not exploit it for various reasons (e.g., plans to use same engine and components but tuned differently for different models down the line, protect placement of higher end models). I think BMW's N54 engine and the engine in Porsche's Cayman may be good examples of this.

I don't disagree with your point though and I wouldn't know how much more power the C400 can safely handle without screwing up some parameters.

Latest news C450 won't be the same as C400

As it will be taken care by amg I believe

http://www.autoguide.com/auto-news/2...ree-years.html


It states at the end

I have a C200 and checking it with the C250 its the same engine but with different sizes of internals.

MB aren't fools to just sell the same car with a detune only, everybody will head to the C400 & tune it back to C450...

I Will wait for the C450 once it's out and confirmed in the middle east By then the ~BMW M2 might be there

then I can chose

OSMS_Carlsson

I spoke with my Headquarters at Carlsson in Germany and they will have a Plug-N-Play unit similar to what we offer currently for the CLA/GLA250 for the C300 and C400. The new engines are going to become very common in a few of the MB platforms, so development for these kits will be based on the engine, not just the vehicle.
The Plug-N-Play units are easy to install and remove and offer a failsafe electronic modification. In the event of a failure or malfunction, the cars will go into a limp mode before anything mechanical is damaged.
I am told by March we should have these units available, not sure yet what the performance gains are, but they will be functional and a reliable choice.

Getting the tuned C300 0-60 "close" to stock C400 times. Improved from 5.7s stock with an aggressive launch to 5.3s with just the tuning. After some more testing I'll see if we can get an E85 tune going for the vehicle to try to crack in to the 4s.

synaptik

with the c450 putting out a rumoured 362-367 hp and 380 torque, i'm hoping a tune can have it hit 420. that would be a great value proposition for a car of this class.

coladin

The M156 engine, the 6.2 V8, was tuned in many. many different ways. They aren't fools but they also know their clientele which many will not bother with an aftermarket tune and the complications that go with that.


The C450 is no different than the PP on the C63. They increased 30bhp with a more aggressive tune, and so will the C450...

Jon@BMS

Was able to do a little C400 tuning yesterday and things are looking promising on that front!

DameMD

Kleemann has a tune for the c400 which they claim they got 413hp - 428tq. That is incredible. This car has so much potential. http://catalog.kleemann.dk/catalog/400-v6-biturbo-cgi-m276/k-box-400-v6-biturbo-cgi/

I can't wait until the c450 arrives. All that power needs a better tuned suspension and brakes.

DameMD

Terry - Kleemann is claiming high gains out of the c400, 80hp+ & 70tq+. I hope you guys are able to match or beat them. It would be good to have more available options on the table :-)

Jon@BMS

We'll be able to make as much as anyone else can make with the platform. Those Kleemann power figures sound pretty optimistic to me though. I'd wait for an independent dynojet run from their stuff before crowning them.

PeterUbers

And I imagine whatever end result u get for the 400 you'll get for the 450
