I don't think that removes the tq limiters. It's a bandaid to be able to use race start with traction control off and the trans in S+ 1. Race start only works in sport mode with trans in M or S+ D. It won't work with traction control off or allow you to redline the gears if It detects wheel spin because it resets S+ to D instead of 1. This just turns traction control off after you launch and returns the trans to S+ 1 instead of S+ D.
yeah i wasnt buying it either but figured it might be worth a try at the track with good tires on to see if it could improve our 60ft times.
Eurocharged told me they have 2 different tunes, one or aggressive and one less.
The more aggressive one needs upgraded spark plugs to go along with it according to them.
Which one do you run? Do you think you can trap higher than 125 with the EC tune?
my only run on st1 + drop ins , 3000 DA , low 70F 1500 rpm , no race start .
On second run of 2500 rpm transmission said hello
if anybody have better 1/8 mile slip lmk , gas is 93 pump
You broke your trans launching @ 2500rpm with only Tune and filters? Damn! I've seen better times 1/8 mile though if that is what you were implying about the 1/8 mile slip. Here's one of mine from the other night. I'm starting to learn the car more and more. Its a 14' ClS63 S. Only Have K&N filters, Resonator Deletes, Updated stock plugs gapped to .025, and Mixed in a little E85. Wanting to see how quick I can get the car without a Tune and hopefully they will have better options by then lol. Cooler temps should yield even better times. My intercooler system needs to be pressure bled IATs wouldn't go below 120. I hope the track is open friday!

I'm actually not sure, I am running the stock spark plugs so I guess it's the less aggressive tune? This car is my daily, so I'm not looking to break any 1/4 records for a stage 1 car.
The Newer "Mercedes OEM" plugs are actually pretty legit and a step colder than the older versions. They do come gapped around .035 or so if I remember right. I think the reason they want the different plugs is to close the gap preventing misfires up top with more boost. Your time seems on par but I think its something like possibly plugs or another issue causing your car to not run at full potential. What octane was that run on Raudiace4?

I think my stock trans was faulty from the factory to begin with .
my best 1/8 mile so far 6.85 , pump gas , what DA is your track?

All my runs were done on 93 octane fuel, and it was in early may in WI at night so the temps were in the lower 50s with low humidity. Spark plugs could be an issue but i was consistently trapping 125.8, so maybe not? 60' is my biggest issue.

Well your 60' is pretty weak because there's most likely an issue with power or boost coming in quickly and efficient unless you're spinning which I doubt being a 4matic. I have stock tires, need new rears and have no doubt ill dip into the 1.7X range without a tune. When you drop 1-2 tenths on the 60' it should equate to even more than that at end for your ET. The MPH will increase when you figure out why your power isn't coming in at its full potential. Have you Data Logged your car? What year? You have K&N filters by chance? lol
Reason I ask about the K&n filters is because they caused a ton of issues being to oiled. Now they are dry and work fine but Oil gummed up the sensors and turbo. I was only making 10 lbs Because one of my Map sensors was covered so was only reading off the Map sensor that is easy to get to and that is because I cleaned it. I think the one under the intake is also the charge sensor but not positive. Just something to check on!

If hes trapping 126mph and only running the less aggressive tune from EC then it could be that's perfectly normal. I expect about 125-126 from only a mild tune, plus being 4matic. A stock E63s doesn't trap anywhere near 125-126 so maybe the power is taking longer to come kick then then it should be affecting his 60'?
Why don't you call EC and ask them which tune they gave you? That would make it a lot easier to figure out if your running at full potential or not based off your trap speeds and times.

I do have K&N filters, but they weren't over oiled I inspected them before installing so that can't be it. I was spinning the rears on launches, my car is a 2014 4matic, but this was with bad tires and heavy 20" wheels. I'll try again in the spring with 19s and stickier rubber.
Here are results of a Powerhaus Performance custom dyno tune and now the car is at DIME R&D for an engine rebuild! Good luck with your car once the weather gets colder. Hope for the best but plan for the worst!!
PS The CLS63s blew up on Powerhaus Performance's dyno after a rebuilt transmission was installed with many codes in the ECU that weren't even checked before doing the dyno pulls! Caveat Emptor!
