RENNtech Bad *** Tune Video- 10.88 quarter mile/0-60 in 2.79
A simple tune pulls this?? WOW and this is just a basic street test not some prepped track..... who knows what this car would do in optimal conditions:

Edit: and remember that since their numbers start higher, the key will be gains over what they started with. Further, for me, the best gains will be in the usable rpm ranges of driving vs just the peak peak rpms that none of us sit at on a constant basis.

Weistec has theirs up already as well, and claiming the fastes E63S, 10.849 1/4 of a mile, their ECU upgrade is only $2,950
who is going to give us the best deal on their ECU tune?

We'll see tomorrow and I'll try not to be sad when the real numbers show their stinking head..
The shop I'm going to is claiming a 20% drivetrain loss for rear and AWD cars, that seems a little high to me. I wish I did a before pull for a base line.
I think it's funny that there are no real dyno sheets from any of these tuners..
I'll get it on video as I always do with my tuning, much like this low boost tune on my Rs211..

It should be in the same setup as it is driven. I'll do the math and keep my fingers crossed, ether way the car rocks and I have no regrets with the OE tune as for the way it drives.
I'll be there at 1:00 pm.

I have updated the classcebenz site with this info and I should have a wiestec tune shortly to review I am looking forward to getting the tunes in and seeing what real world numbers we get out of them.

Didn’t Renntech run (claim to run) a 10.6 with their initial tune on the W212? And all the tuners speculated how much potential there would be and got people to jump in the mod game with both feet! Then a year later when real world customers started hitting the track stage 2 cars could barely run better than low 11s and full turbos cars barely broke mid 10s. I think Renntech even tried to explain it away by saying they no longer offered their magical early tune. I hope we’re not getting lied to again!

Once my car is broken in (or at least have access to race start), I'll run the quarter mile stock. Will then tune, likely Weistec, and then run again. Going to stop at stage 1 on this car, as these perf numbers are more than enough for a 'daily'.

Or conditions, Weistec was on a track with DA unknown... RENN's was on a street and we have no clue about the conditions. But yes 91 vs 93 is a difference.

Is 93 available in Cali?
In most places I only recall seeing 91. Haven't really looked closely at pumps lately as my cars use regular and I use race fuel in my bikes.

Nope max octane is 91, the one thing that bugs me here... you can get race gas in certain locations though but its cost prohibitive for a daily driver sedan IMHO.
Ive seen gains of 20-30 whp on turbo engines with 93 octane vs 91 (in the RS world for example) and this is whp.

Good points, at least in this case we know that the oem car is generally putting up better numbers from the factory than the W212 did thru so many videos, tests, magazine reports, etc so maybe the results are straight up. Granted here, we dont know the slope of the road or the conditions- we will just have to wait and see. Im slated to dyno my car pre and post tune next week. Ill post up after.
The more time I spend at the track and more data I accumulate, the more I realize that the biggest proble with the W212 is not the launch. It’s the power that gets pulled during shifts. It defeats the purpose for AMG to brag about their MCT millisecond shift times if they have to pull power during the shift to avoid problems. BMW (and Audi) got it right by recognizing the ZF8 tq converter auto was the right transmission for the job.

RENNtech quotes crank adjustment numbers I think.... so take the 773hp and adjust down to whp based on drivetrain loss.
Edit: and remember that since their numbers start higher, the key will be gains over what they started with. Further, for me, the best gains will be in the usable rpm ranges of driving vs just the peak peak rpms that none of us sit at on a constant basis.

As mentioned before, those are just calculated numbers for reference to power numbers published by MBUSA. Important are the wheel power and the gains achieved at the wheel.
Our wheel results are 665whp and 670wtq, which are gains of +70whp and +72wtq.
We'll try and go to the track (PBIR) this week. Currently the car is on the lift to finalize the downpipe development.
For everyone that wants to read more about the whole crank vs. wheel hp and peak gains vs. gains at the peak, we created a section on our website.

Well I tried to get some dyno numbers but the car didn't like the dyno dynamics dyno and threw a fault code. No matter what configuration the car was in.
So who's up next ?
