Not sure if this is the right place for this or if it's already been asked, but since the C250 will be a turbo'd 4 does this mean it will easily be chippable to squeeze out another 40-50hp like the Audi and BMW turbos?

Not yet chipable, because the ecu isnt easy to tune. But there are powerboxes , easy to instal in 20 minutes.

You could also just install a manual boost controller and raise the boost a couple of LBS and just let the ECU adjust.

Actually Brabus has a chip, 204-B25-00 BRABUS PowerXtra CGI B25
+ 26 hp, base C 250 CGI; 169 kW (230 hp), max. torque 350 Nm
on their USA website, scroll to near the bottom of the catalog

http://www.brabus.com/en/raster.php?...49&modell=3644

They are the experts, wouldn't trust anything else.

@lithium332. Hmmm... missed that one. Anyway truly AMAZING performance from a 1.8L I4, why didnt MB get 133 HP/L out of the 3.0L and 3.5L 272 engines? And HUGE gas mileage. I want a 466 HP twin-turbo 3.5L 2014 E that gets 30 MPG hwy.

Brabus is also a tuningbox, not chiptuning but piggypack.

Expensive. The one from Brabus costs around $3k and adds 36 hp.

Holy Shiiiii

What happened to the days when I sent away to Neuspeed for my 1.8T Passat's chip...$200?

I guess you need to pay if you want measurable results...

Dumb question, my C300 is the most powerful car ive owned (coming from old toyotas) does 36 extra HP actually FEEL like that much?

It all depends on initial oem turbo size. If it's a small size for minimum lag, you can't get much more boost out of it, before building up exhaust back- pressure that is TWICE the boost level, and destructive to the engine.

To roughly compare the turbos, find out what the compressor inlet bore diameters are.

First thing is minimizing intake and exhaust pressure drops. I used a Dwyer 100mm H2O differential pressure gauge to find restrictions in the rx7 intake, and the oem air filter was fine, for example.

There is a current thread about Renntech developing a power kit for the C250.

Renntech-C250

From a business perspective, I wonder why the price is so insane. Does this price actually reflect the R&D costs or are they just inflating the hell out of it? Assuming they inflate the price wildly, wouldn't they make far more profit selling it at a reasonable price and tripling their sales?

I heard it actually makes a difference, though I haven't tried it personally. It shaves off around 0.3 seconds from the 0-60 time.

There should be plenty to see for gains. Keep in mind its a small turbo which spools low so it is going to run out of air up top but the gains in torque is what you'll feel and use around town. The limitations will ultimately be the cooling (both intake and coolant) and the fuel (measuring injector on-time and lambdas to see where they are running out). It doesn't have to be so expensive, no. The US players will start to get involved and still make hand over fist charging 500 to 900 bucks. Software is the bread and butter of tuning companies. Its much harder to make that kind of profit margin on hardware. Keep an eye on what BMS is doing for the c250 too. Their 335i stuff has a following.

i tried a RaceChip piggyback box.
It connects to the boost sensor and manipulates the readings.
I drive a C180 CGI and was able to get +10HP and +10N Torque on the low setting on the dyno.
Will probably play around with the settings bait more when i have time.

C250 CGI is a twin turbo - one dealing with low engine / road speed boost and the other, larger one handling the higher rpm / road speed demands. The smaller turbo helps eliminate turbo lag.

My remapping exercise on the diesel engine was done by opening up the ECU. It works perfectly with improved mileage and stunning performance. Blows most gas engined Cs away (C63 and the like excepted of course!): zoom:

Did I miss something? the US C250 (CGI) is a single turbo, right?

It is a single turbo. I'm not aware of any MB 4 cylinder worldwide that is a twin turbo.

Whew, thought I had gone crazy and missed the additional turbo and intercooler in the engine bay. Are we sure it doesn't have one of these http://www.electricsupercharger.com/products.html installed?

We just did some dyno tuning today also. The turbo is small but gains were promising. Posted them on our forum to avoid any sponsorship conflicts.

Check the link I posted above.

Terry are you going to be tuning for 93 octane?

Thanks.
