0-100 mph Times, Stock and Tuned
 

Do you guys know what range the 0-100 mph times shoud be? tuned versus stock?

I just had the VBOX tell me I hit another 3.3 0-60 but I only hit 100 at 7.8 during the same run. 7.8 seems off to me. 4.5 seconds to get from 60-100? I was floored the whole run in S+. It felt like I was moving pretty good. I actually never did a 0-100 before the tune. I can I guess by just swapping my ECU's.

Is this 7.8 time jacked up? I never really followed this parameter much.

I realize that drag is a squared function of velocity. But these cars don't have a lot of drag. Just seems slow to me. But I don't know for sure.

OK, Now Things Make Sense!!!
 

Well Guys,

I found the perfect very low traffic section on a 4 lane expressway to do my runs. It might be just a bit too short though for a full 1/4 mile run. I was able to get these nice times though yesterday afternoon with the following parameters:

Traction off
AC off
Windows up
S+ mode all the way
Suspension at double bars
3k rpm brake boost
tires at standard pressure
no passengers

With these settings I was able to spin all 4 wheels for the first time for about 1/2 to 1 second (quite audible) and still got these numbers:

Turns out the 2017 Hellcat does 0-100 in 7.2. So it looks like I'm in some good company. The AMS tune is VERY REAL GENTLEMEN!

Nice to see that 7.2 is achievable. Great for you. Remember, as I mentioned, I spun four wheels for at least 1/2 second. So 7.2 with everything perfect is certainly achievable. Additionally, I have no idea yet what kind of shape my air filters are in. I know the car is due for service. You did not mention what other mods you might have. This was done with nothing beyond the ecu tune, tires that might be due for replacement, and questionable breathing from the intake. So stay tuned, this might, and likely will, get better.

FYI I have a Eurocharged tune on my 2011 through the OBD port. I know they make good stuff. However, they badly dropped the ball on me when the flashing stopped working and I have been stuck with stock profile. I tried more than once, even sent them a youtube video showing them how it was not working properly anymore. Someone ther named Solomon said they would straighten in out. Then they went quiet. So I went with AMS this time. Both reputable tunes. However, the follow up customer service from them didn't sit well with me. And I don't care a lot about the 2011 tune problem as I am selling her to some VERY LUCKY person and if selling it should be stock anyway.

Enjoy your fast car!

Not sure what to say on this. Maybe it varies from car to car how the clutches perform? Maybe the tune somehow helps this due to the huge additional torque? When I do it, I full on brake with left (of course, duh, lol) But I dont stomp the throttle, I ease it up. Beyond that I don't know what to say. I believe RS is supposed to go to 4k insn't it? It does on my 2011 M156.

This is the best answer I have fellas.

Cheers.

A tuned W212 E63 will be faster most of the time than a stock very strong W213 E63s. However, most of those gains by the W212 will be seen more on a rolling race than from a standstill. There are cars at 4000+lbs with less power that can outrun all our cars from 0-60mph due to awesome launches.
The 70/30 fixed split AWD will always be slower than a variable AWD system from a dig (HP and weight being reasonably close). The W213 has had the launch/TCU algorithm improved over the W212, so goes to show it can launch better than a tuned AWD W212.

All this to mean if you can launch anywhere near as well as the W213 with your tuned W212, you will quickly reel it in and pass it up well before the 1/8th mile. Gets worse for the W213 on a roll.

Also, a tuned W213 is not showing to be significantly more powerful than the tuned W212 (W213 has ~20 WHP more but some 50-50 WTQ less except with Eurocharged tune). Only one vendor has shown power and track times that is in the mid-10s. Most are in the high 10s (like the tuned W212s). The W213 is the dream car (between the two) to leave stock cos there is little to be gained from tuning it as far as raw track times go.

Now let us compare to the competition.....RS7 are not running much faster, but they can certainly out launch either AMGs. M5s will be the ones to watch..... too new to tell right now

Additionally, I had a '17 C63 for a week and can say the newer version of MCT is no better, still a laggy start. I know it's the C platform but I think the setup is the same.

Peter,

I am told by FFTEC ( an AMS partner out here in the Bay Area) that you can't really do a pre and post dyno the same day. They suggest to me that I bring the car in with the tuned ECU first do the 5 pulls for $150. and then come back a different day after getting at least one full "drive cycle" on the original ECU. They say that the numbers will not be correct if the ECU has not registered some minimum amount of time being driven.

My thinking was that they are just trying to get paid twice. But after looking a bit more into it, it sounds legit. The extra $150 to run the stock ECU isn't that big of a deal. But the 35 mile drive and time there is a bit of a headache. Ugh. But I am scheduled to at least get the tuned ecu dyno'd in a few weeks! I will post results after I get them.

Side note: I am scheduled to take the car in to the dealer for some minor warranty fixes tomorrow so I put the stock ecu back in it yesterday. There is NO DOUBT that the tuned ecu is way more powerful! Car feels slow now. lol

My cars personal best is 4.3 60-100 but that's starting from 2nd gear and winding it to 8000rpm, to give the 60-80 portion a kick start. I wish it was faster man :(

That's moving :zoom:
