https://mbworld.org/forums/s-class-w...ml#post3708008
Forget peak#'s this DD is Stiletto Heal in ANY mans heart
370 RWHP 505 RWTO STOCK OUCH
POST ECU 428 RWHP & get this 680 RWTO
gains are nearly 60 RWHP 180 RWTO
For good comparo Powerchip recently tuned A DIFFERENT S600 w/another DD down the street, their Baseline STOCK #'s were 450 RWHP 560 RWTO
gained only 40 rwhp 100 rwto

what's up with the goofy mph axis? makes it appear like the car was in 2nd gear which some would argue could explain the hp/tq discrepancy.

I believe heat-soak could be a factor here, they ran this S600 17 times on Dyno w/stock cooling system.
I agree rwhp could be tad higher I.E. 400 tops in stock form on this DD

I'm not certain about that but, a properly setup DD will show LOW stock #'s like above on ANY 600 TT model car...

***quick side note...Dyno Jet has a mode that when you can find tach signal it will somehow extrapolate the TQ from the HP vs RPM, when you use this mode it grossly miscalculates the TQ figure, lets put it this way I have dyno figures that say I make 950+RWTQ when using that mode and we know that aint true. I cant comment if thats whats wrong here though, looks like a healthy car!

That's hilarious since TQ is the only measureable factor and HP is a calculated value off of TQ haha.

Thericker - that Dyno Comp dyno chart is insane! 520 rwhp and 710 rwtq, on a Dyno Dynamics?
Don't know about that car (and it's OT for this thread), but all the more impressive if it's on AZ 91 pump.

Yes most higher 680-700+ rwto curves drop-off like seen on charts above...Example SL600 RENNtech ECU/TCU on 100+ Octane DD see any similar curves?
I think this id same DD Hooleyboy & you use?

Based on the car only having 3 pulls (as shown in the chart) shows that the customer was only interested in a basic "can" tune rather then spend the time on the dyno dialing the car in.
In the same respect with only have 3 pulls there is no way this car was tuned for 100oct. Maybe when the guy raced it at the track he put in 100oct but not on the dyno. Any tune over 93oct can no longer become a "can tune." It takes alot more pulls to dial in a race map as i'm sure we all know.
If you want I can post up some 600 dyno charts (other than this one) so we can compare curves and what not. Its not everyday we see 600 charts.

Since torque has to equal (hp x 5252) / rpm, I don't understand how it would give an inaccurate RWTQ reading - that should be the easy part, once the HP is plotted...

I asked him before I posted.
EDIT: just to be sure I will have Rich pull the VIN on the car and find out 100% for sure what was done to this car. Also I just got off the phone with Ken (again) he says he has no clue what oct was in the car. He also said with only 3 pulls its not consistent with 100oct dyno tuning.

Very nice gains! Have to look past peak and admire the HUGE gains above the curve in that dyno.. Looks like 80-90rwhp over the main MEATY part of the band.. Add the huge TQ into the picture and you will drop a full one second plus off your ET. Granted you can get traction now!!
I bet daily driving has become very exciting..

The difference between the two top runs was about 30 minutes of cooling with two large fans blowing on the intercoolers. They were really cold....
Unless someone can figure out how to keep the IAT's down and those intercoolers cold, the green run will be what you get. We wanted to prove a point that these cars heat soak and they do...

Some of you guys are mistaking the SL600 Dynodynamics Dynocomp as the LET tune or my SL, it's niether I posted it for reference to compare to LET's current work on MRAMG1's S600 while using a different Dynodynamics in Chicago vs SL600 in Arizona.
SL600 reading 520rwhp 715rwto is an old graph belonging to Joe Curry, noted in supplied link on my OP, I've seen plenty of AFR's from RENNtech tuned 600/65's they're @ 13-13.5 super LEAN I.E. using 100-105 Octane period...

Does Eurocharged have something else planned for me?
