burger tuning (BMS) and C400

I noticed that BMS now has a plug and play tune that increases turbo output 3-5 PSI. http://burgertuning.com/mercedes_ben...nce_tuner.html.

has anyone tried this?
I have not been able to find any results or what type of increases this yields on their website.

My C400 is tuned on Map 2. I'm in Calgary at high elevation so results aren't quite as good as sea level but I notice huge gains. Definitely worth the low price. Tuning an equivalent Audi S4 with APR is about $1,200.

Been meaning to get to an AWD dyno for results but haven't found the time.

Hi A5HLEY2. I see you running on map 2. I am currently running on map 1 with 91 octane. Did you use a higher octane or ethanol/race gas mix to run map 2?


Also on map 1 after putting the harness on and off a couple times taking the car in for service, I do notice the difference acceleration wise compared to stock.


I live in Toronto, Ontario.

How hard is the install of the harness? I can't seem to figure out how to disconnect the harness lock on the 3 points on the engine

Any tips?

Super easy. Just push down on the tab and pull out at the same time. You have to push down to disengage the lock when the plug Is snapped in place. Easily down with a flat head screw driver. Yanking does nothing. You have to push down and pull out at the same time on the tab.

Thank you! How long have you had the tune? Have you had any issues?

I've had it for about 3 months. No issues plugging it in and unplugging a handful of times. Noticeable difference with it plugged and stock though.

I run map 1. I tried map 2 but it wasn't as consistent for me with the fuel I have available.

Probably same or slightly better than the unreleased c450 for next year's model. No dyno to confirm though.

On the C450 AMG Sport I'm ordering I will avoid Burger tuning with my BMW I had it on, there was an increased lag/delay/relay on the paddle shifters when changing gears. Found this out at the track, had to go back to using the auto stick for the fastest shifts. Guess that's what "piggyback" tunes mean.

Gains on the C450 would be interesting to know, especially since this car is turning out to be a beast compared to the currently offered and soon to disappear C400.

Yeah, I only run 94 octane which is readily available at Husky and Petro-Canada in Calgary. My fuel economy isn't great though..... I run only in the highest Mercedes sport mode with map 2 and I can't get 450km's from a single tank. The sport modes holds gears longer and blips the throttle on downshift.... all of the things that make the car feel sporty are terrible for fuel economy. Oh well.... I'm coming from a CLS63 which was barely getting 18mpg, which is worse than a full size pickup truck.

Hey HT,

When you say "track", you really mean the parking lot at the local Walmart, right?

The Streets of Willow Springs race track, a little scared you think of a track as a parking lot or local Walmart.

"after putting the harness on and off a couple times taking the car in for service"


I have been reluctant to consider a tune out of fear of voiding the warranty. Does the computer log the changes made by applying the tune or is it completely undetectable to the dealer as long as you uninstall prior to bringing the car in for service?
Thanks!

If you damage something by adding an aftermarket accessory like a tuner you are responsible for the resulting damage. But having said that, the tuner does not leave fault codes or traces behind once removed.

BMS tunes power the worlds fastest turbo BMWs. If you were having an issue shifting with one of our tunes definitely capture a JB4 datalog and shoot it in to tech support so they can help you resolve it. Probably a simple setting or firmware issue.

had a chance to data log and tried a few things with map3

i was able to hit 15.5 lbs of boost.

mostly 13-14+ lbs in mid power band and tapers down as thr rpms climb. this was done in 85d heat, full ac, comfort mode, esp off and 4 gallons of E85


no long freeway pulls. just empty street pulls just below 3 digits.

since OE tuning is hitting 16 lbs i knew running just under that should be ok to try.

i place data logs up later...

very happy i can adjust a bit on my own. without responsibility to the tuner since im taking my first step of customizing stage 1.

hope to keep learning and adjusting.
