No need to clean your engine before you take the picture, just take it. Everyone especially me wants to see a AMG s/c on a n/a AMG. (noobs: s/c = supercharger & n/a = naturally aspirated). I'd show you pics of my car's engine but there's nothing to see, it's bone stock.

In addition to improving part throttle maps and throttle-by-wire curve.
They definitely know how software works and know how to modify it.

New dyno with superchip custom tune is coming up soon when the body shop is finished with my car.I understand with the superchip tune ,Steve (c55m8o) put down 307whp 320ft-bs of TQ Superchips!I will ask him to scan his dyno. Like I said I think the Powerchip and Superchip programming is very good.Vadim I think the Powerchip is what you guys use right?I think both chips are excellent upgrades.Mario(E55cent) has had good success over there in Cali with the Powerchip in his 1999 E55.
Keep in mind that Steve's chip was customed tuned and I'm using the same exact chip he has.We have a guy over here on the East Coast that does custom chip tuning for Superchips.

This is not a recent picture, but it is something I had stored on my hard drive.
Tuning is still be sorting out. F/I is turning out to be really tricky. I was running really really lean and the knock sensors were shutting down cylinders, so I had to redo some of the fuel management. I just added a boost a pump onto the fuel pump, and added a FMU from Kenny Bell to keep the fuel return line closed up a little longer than stock.
Enjoy.

coolcarlskiC43: Stock cars are usually this rich. My guess they are trying to be as conservative as they can be. Customer was going to go with exhaust and play with airbox, so we left a little more fuel in it.
Dan: Renntech has been doing AMG kompressors for several years now. I can not believe they have not finished tuning them yet.
FMU will work, but start with 6:1 ratio. Find a Mustang shop that has a dyno and knows how to tune FMUs and you should be able to get close. Good Luck!

Thanks Vadim for your help. Josh at HOP has a dyno and we are going to try a voltage clamp on it first. Our goal is 4.9v clamped. The software that is on the car now was supposedly custom tuned by Oliver @ Renntech, but never tuned on the dyno. Furthermore it is clamped at 4.5v through the use of some resistors on the HFM. If the voltage clamp doesnt work, I am going to reflash the software back to stock.
My two thoughts are that Renntech most often sells off the shelf pre-programmed software. The software is probably ok, but was most likely tuned on one car, and then sold to the masses. I really dont know for sure.

I am on the same boat as Dan
I have a wideband O2 sensor installed before the cat,. after the header.
and I am recording as high as 16:1 at 4psi.... the car constantly run at
4.3- 14.7 at no boost to idle........ so I can't see why the stock cars are running as low as 10 a/f
I already have 12:1 fmu installed., and piggy backed the MAF,. gonna do some convertion to the fmu to give out more static boost
btw. any guys know what is the currect injector size on the 208 55
AMG?
I am thinking going for larger injectors

Dan.,
this is something Tony at superchargeronline.com put together for me to raise the static pressure for the FMU unit.
http://www.superchargersonline.com/p...=SODC-FMU-CONV
P.S if you gonna buy it., make sure to tell TONY that you need a 12:1
AND SERIOUSLY!!!.. .any body know where can I get a custom software in Cali area.,?

that is true but.,the ECU won't mind to fly down there., but I never believe someone without the actual engine would be able to tune the ECU correctly!...
coz, I have a custom blower installed with 7psi...... ... only if he did something like that before., if not he would need my engine.,,. too

Also this might be a good solution for you.

Super FMU, stupid name but I hope it works.

Well, the voltage clamp was installed today. A/F ratio is better (in the mid 12's). Power is still not where I want it to be. I need to flash the software back to stock to have a good baseline to work off of. The renntech software pulls timing way too far back.

Description
The VC2 Voltage Clamp is designed to condition the output of voltage based air flow meters, MAP sensors and mass air flow sensors. It is often used to avoid fuel cut in forced induction applications. Under normal operating conditions, the VC2 outputs a signal that is identical to the signal present at its input. When the voltage of the flow signal reaches the internally set clamp level, the VC2 maintains a constant output voltage at the clamp level as the input voltage rises. The VC2 differs from the VC1 by offering a hard clamp function that is user adjustable. The hard clamp allows the output to track the input right up to the clamp voltage. Once in clamp, the VC2 maintains the clamp level with high accuracy regardless of overdrive.

So is your system running 12 A/F all the way up now?

I am going to try colder plugs to prevent detonation.
Higher Octane gas definitely helped (approx 12hp gain because it wasnt detonating as much).
