can't wait to get this

Waynezworld

Sorry guys been working too much. Car has been running great, I sit in a lot of traffic to & from work so I actually haven't been using it every day. When I do activate it, it works great. The next tempting thing is I want to do the exhaust on this car. Someone asked about the crackle from the exhaust; the c400 has none even in S+.

How's the bluetooth control?

Waynezworld

The control works fine but the interface can use a overhaul, it's very basic

Are the installation instructions the same as the c250/300?

I got the test unit for my c43 but I'm not sure if I follow the c300 install instructions

removedCFGaccount

Christ, you got no instructions?

sterz85

I think it might have been a small oversight or the installation might be the same as the c300. After all, it's just two plugs.

I got the test kit for the c43, pretty sure they rushed to ship it out since I was asking hourly for the tracking number.

The package looks great though.

photo?

I'm jealous.

sterz85

Sorry if it's huge, I'll resize them later. Box might say for the c300 series but that's because the c450/c43 packaging wasn't ready when they sent the test unit.

Now, I'm really jealous.

Send me a message when you get it installed buddy.

If it makes you feel any better, the driver side hood latch is messed up so I have to pretty much jump on the hood to get it to close.

I'll be installing it tonight, but to confirm, same install process as the C300?

Looking forward to hearing your results! Just picked up my 43 2 days ago. Very interested in this. Good luck!

Im sure the "sensor" locations for your c43 wouldn't be in the same place as the C300 due to the different engine layout. Same plugs most likely, different mapping in the tune Im sure but if I had to take a wild guess the sensor you are looking for will be near the front of the engine, maybe under the engine cover, but probably down between the front of engine and the radiator area in a "crevice" somewhere? .

Any news??????????

Any installed picture on the C400 under the hood?

No answers to these questions?

So, how is the chip overall?

DinanCars

I apologize for the delay. Haven't gotten into the habit of checking this forum regularly yet.

On a scale of 1 to 10 on install with the 2.0T being a 2 the 3.0T install might be a 2.5 or a 3. Haven't finalized instructions or anything but the sensor connector is pretty easily accessed. A bit of an odd angle but that's about it.

I am not aware of the processes in MB land so I will answer the dealership question like I would on the BMW front.... No tune is undetectable. However, the amount of effort to find traces of a tune is where the differentiation lies. With the piggyback approach if it is removed there is no way for a dealership to detect it has been there with their available tools. That said if something catastrophic were to happen and an engine or transmission destroyed chances are a factory team would come in to diagnose the issue (PUMA on the BMW side). These individuals have factory tools that could delve deeply into the electronics and find inconsistencies that would indicate a tune was present. Its all spurned on by a large warranty claim though and the chances of it getting to that point are minimal.

While the SPORT tune is safe its whole purpose is to be a commodity item that is attractive to the masses. At a $300 price point it simply isnt possible to extend a factory matching warranty. It ultimately comes down to our matching warranty coverage that include parts and labor and simple economics. A a single minor claim for any number of random small things could be a $300 bill just in labor at a dealership and erase any possible profits instantly.

Well said.

Yes, yes, but how is the process going?

Expected ship date?

DinanCars

We had "technical difficulties" with the first C43 test unit so a new one should be in his hands today to install. We shall see what comes from that before any estimates on shipping at this point.

removedCFGaccount

Damn....

Can you elaborate a bit more on the "technical difficulties" as in a simple installation issue or a more serious issue causing drivability problems?
