New H&S ECU in my '03 C32 reactions
Well, after 250 miles with this new H&S ECU I have just one word:
..TORQUE!!!!
1. Out of the line is quicker, and explosive.
2. At the highway the car is FAR quicker and 130-140 is so easy to reach. Among third and fourth the shifting is quicker.
3. Same top RPM.
4. The car sounds louder, cooler, and deeper.
5. I feel the Kompressor working more efficiently and “listen/hear-able”.
6. Between 800-3,500 is better than stock specially the reaction.
7. Between 3,500-5,500 the improve in torque considerable,
I really fell my back squash the sit. It really makes me remember my Fiat Turbo when reached 1.6 -1.8 bar when the turbo opened. If I need it to compare with the stock C32, imagine that in this range you gave an “over boost” that may be generated from better timing and flue efficient mixture.
8. Between 5,000-6,220, I feel quicker than stock but I must say that the improvement in torque is that big, which makes me lost the sense or perception that where is the improvement in the other RPMs.
Finally, I’m waiting for the BMC panel filters, and I’m thinking to replace the plastic Y-connector that brings both sides into throttle body from the SL55 Kompressor (Bigger diameter). After everything is done (ECU, BMC filter, and Bigger Y-connector) I will dyno and post.

-Will the sl55 y-connector fit? I don't know but I'll try.
-How much for H&S ecu? US$ 1,290 with shipping to Germany and return.
-What octane gas dos H&S? well I higher better, Thomas told me that the program that the upload in the OEM ECU does set up depending the octane. Thus, the figures that you may see at the H&S web are the minimum that you may get. Also he replayed to me that they had used the same program with 100 octanes in Germany and of course the car goes much faster.
Finally I had the H&S ECU on my old C43 and works excellent for a year, so far.
bye.

I had a look the the H&S specification.
450 NM to 485 NM
354 HP to 376 HP.
You may indeed feel a small improvement, but really this is nothing to be shouting about. For the price you paid I would say it"s ok.
I am waiting and hoping for something to come out in the 450 HP range with a torque about 540. That is what I think of in terms of feeling the extra power in your but ! MKB kit is close, but at a price of 10-11000 $ ... forget it !
I hope vadim comes along soon and bring us an extra 100 HP for XMAS !

Thanks bverotti, 
by the way the H&S specification in torque is right (450 NM to 485 NM) but the hp are not right added (354 HP to 376 HP) because they claim 26 hp more, thus 380Hp and Thomas excused for that.

What does H&S claim to do to gain all of this HP?
ECU modifications on NA cars aren't worth squat, except to advance timing so you have to run higher octane fuel. Even then there isn't much gain. You can give a better SOTP feeling by playing with the fueling and ignition timing, but overall power isn't increased by a whole lot.
When you get to turbo or supercharged cars, you can realize huge gains by upping the boost and adjusting the ECU settings accordingly. However, just an ECU change without increasing boost pressure (pulley change on supercharged car) is not likely to free up 26hp with no other changes. It seems unlikely that Mercedes left that much HP on the table when tuning the SLK/C32.
Aftermarket tuners can make a lot of claims for power gains, but it's not necessarily how it's going to perform on YOUR car. Many times tuners will make a bunch of modifications to the car (like intake changes, cams, heads, exhaust, etc) and run it with the stock ECU. Then they'll run a modified ECU and see huge gains due to tuning for the other mods. They can now claim that they saw XX gains on XX car, when it's not really applicable to your average joe who's only making an ECU change on an otherwise stock car.
Anyway, just my .02. I'd be interested in seeing a before/after dyno of just the ECU and also the corresponding A/F measurement from a wideband O2 for both before and after.

Totally agree, I feel that my car is a rocket every time I get it after the service is beeing done and that is only because I have been driving loaner for the time of service. I also used Sunoco 94 octane gas and it felt quicker--------I don't know if it were just the feeling may be because I expected some difference from better gas. Personally I do not believe that you can feel much difference from ECU change so I say Pierre simply was out of his car for a week and that is what felt different to him.

Hi,
if you have fuel with 91 octane in the US then it´s the same fuel with 91 octane in germany. There is no difference. 91 octane is 91 octane
In germany you will find 3 categories:
- Super (95 octane)
- Super Plus (98 octane)
- Optimax (100 octane)
Mercedes-AMG says that its recommended to drive super but i always drive super plus. It´s better for the engine cause of the "cleaning effect". And maybe the engine reacts more powerfull.
One 4 times a year I drive optimax. But you can only get optimax @ shell fuel stations.

this might be off-topic, but has anyone heard the high pitch noise when the car is over 140 mph? Finally drove it up to 158 mph (the speedo is off at that speed about 3-4%). after 140 the audio is automatically turned off, but i also get this weird high pitch noise from the center console after the audio is off. is that supposed to happened?

Yo Frank!
you´re right: I have this screaming noise too. But my radio doesnt switch off automaticly. AMG makes this special for EU cars cause the driver should know that the speedlimiter starts with his work.... Everythin´is allright with your car.

Same thing with the benz. And didn´t some1 write somethin about dyno and his car that has ~ 300 HP? My car hast 354 HP and is the same as his one...
@ FrankW: AMG told me that if your car (C 32 AMG) is delimited on the 1st stage it will run 280 kmh. With full delimitation (2nd stage) it makes 10 - 15 kmh more. Thats 290 - 295 kmh!! Imagine that...
