Took the CLS63 last night to TMP for a few runs.
It's 2016 with 34,000 km = 21,000 miles
Recently serviced @ 31,000 km (Oil Change and Spark plugs)
Stage 2 ECU E30 dyno tune, TCU tune, De-cat, UPD intake.
Running about 1/4 tank.
Temp is around 77F
Humidity is 80%
DA around 2000 - 2300
Rear tires are stock pirellis, worn down - 25 psi
Front tires are stock pirelis, good shape - 45 psi
Suspension S+
Transmission S+
Traction completely off
Track prep is garbage! Always is on Fridays! Wish they prep it like Saturdays and Sundays as I'm sure people won't mind paying the extra $20

Congrats!
You've got to be happy with those numbers.

I assume you are running EC Slavs E30 Tune / TCU tune combo considering where you are located.
When you refer to the ECU tune as a stage 2 E30 ECU tune... are you saying it's a little spicier then the conventional EC Slav E30 Tune? I do note that your dyno does show about 20 more awhp than my EC Slav E30 tune, but that could be down to variances in the dyno.

Thanks in advance for any additional info you can provide...

 

Thank you! I am relatively happy given the conditions!
Went in there hoping to crack 10.8s cuz of temps/humidity and did that!
I am just unimpressed with the track prep on Friday nights!

Originally, last year, I had a stage 1 tune. Since then, Slav has revised the tune and it's different from what I've got told.
It is a dyno tune E30 file. Stage 2 otherwise? Sorry for confusion.
Slav did the tuning for my car and brother's car.

Brother's E63 put down 675 whp on the same dyno, that same day.
Only explanation that comes to mind why I put down extra power is perhaps due to the UPD system (spacers and filters)?

Now I need a new wheel set up and stickier tires and cooler weather for better numbers.

Iron Sheik

 

Thanks for the quick response. I put down almost the exact same numbers as your brother did then, I'm stock intake as well.
It appears your intake flows better up top then, all other things equal. Did you both make similar torque?

I invested in some Nitto 888's for the rear for the exact same reason as you are facing now... traction! lol
I'm waiting until cooler temps before heading back to the track.... our Houston humidity isn't conducive to summer running.
I'm amazed, having lived in Bramalea that your DA was as good as it was for July.

 

No problem!
Intake does help with better air flow, especially top end!
Him and I made similar numbers regarding tq. I may have made 10 more than he did?

Do they make Nitto 888 in our sizes? 255 fronts and 285 rears?

Weather has been brutal the last few weeks. Yesterday was ok and it did get cooler towards the end of the night; however, cooler weather and poor track conditions made my car way too tail happy and decided to call it a night.
Could have made few more passes, but what's the point when you're not hooking?
Made the drive from Waterloo, so wasn't too far.

Iron Sheik

 

I'm running the Nittos in 295 width in the rear and the stock Pirelli up front.

 

did you manage to test your 100-200 km/h times?

 

Wow, damn nice times in poor conditions! Like that mph!

 

No I didn't unfortunately.
Guessing around 7s??
Brother's similar set up, minus UPD, ran an 8.0 seoncs 60-130 mph on draggy that night.

Iron Sheik

 

Great numbers -- have you ever launched with comfort mode suspension?

i am at 700 ft and correct your car is 10.6 range

nice!!!

 

is his quarter mile also in 10s or 11s? I think it would need a 6.xx 100-200 or 7.xx 60-130mph for the 10s.

 

His was always 11.0x that same night loool
He's getting major service done today.
Oil Change, spark plugs, transmission, both diff's and brake fluid.
Adding his UPD intake spacers/filters to see if it'll make a difference

ps. he did run draggy that same night when the weather was much cooler and got 10.75

Iron Sheik

 

DA plays a huge roll. Especially after 70mph when your hauling up to 130. Better da and your times are gonna drop very well.

 

 

Damn, coming back from the future, huh?

 

loooool
Those were back to back with tracks prepped
Now it's colder and Prep is bad. Pulling only 10.8 And 10.9

Iron Sheik

 

Today's runs at TMP
I'm 13 and brother's E63 is 519
Don't think it'll Ever get better than this Even though It WAs not ideal conditions tonight

Iron Sheik

 

Fantastic times for only E30/TCU. You've got to be very pleased with that 10.5. Your 60 ft was pretty impressive as well. Congrats.

 

Can you list all the specs for your car please?
E30/TCU with filters... anything else? Your car is a CLS63S correct?

 

Ecu/tcu E30 tune
de-catted.
Upd spacers and filters
everything else is stock including tires.
Ran full weight with tank being almost empty

​​​​​​My car is cls63 yes

Iron Sheik

 

Thank you kindly
That 10.4 vs 10.7 slip was my brother and I running against each other

What does your brother have in mods & car?

 

Mine's 2016 Cls63
His 2016 E63

Exact same mods
MY car has 22k miles
His car has 57k miles with recent service done:
Oil change + filter
Air filter
Spark plugs
Transmission fluid + filter
Rear diff
Brake fluid

Iron Sheik

 

It must come down primarily to gearing and weight then, because the power is similar.

 

I think they have similar trannys!? But not exactly same
CLS is much easier to launch though.

My car made bit over 700 whp and brothers made shy of 690whp

I was running almost empty tank.
His tank was over 1/2 full.
