Dyno result!
Finally i got my car on the dyno yesterday and would like to share the result...you can see the engine HPO and in the reading you'll see the RWHP..I realized that the HP is not transfering to the RW as it should be...VRUS and Grumpy, your opinion will be apreciated

33% is a large loss. Almost too much.
Use 17%.
Manual cars are around 15% (usually) and autos are around 20% (usually). Our (5sp AMG) is an 'efficient' auto (whatever that means).

chocalate cookie granted to you....thanks for the information, but what can i do to get the proper power to the car...the problem is A/F ratio sucks, i know but what is the solution...i am really confussed here

So at high rpm this should behave very close to a manual in terms of drive train loss, but a bit more due to its high mass / inertia. You may need to apply a higher DT loss at low rpms before the TQ locks up, but for peak power this is not necesary.
Correct me if I am wrong anyone.

The first time I read this thread, I thought it was a prank post. 584 HP? Not from the data in the posted chart. With the mods listed (K2 w/TB), 580 corrected crank HP is not an unreasonable expectation. My guess is the dyno shop fudged the chart to give an expected result, not a measured result. If the car were mine, I would take it somewhere else.
From the data chart it looks like the car is bumping up against the speed limiter, so the peak HP indicated is somewhat lower than what the true peak HP would be at 6100 RPM. Also note the test temperature - really high. Assuming there are no correction factors applied to the data in the chart, this car is probably make 470-480 WHP, and could probably make a little more with an ECU tune to pull out a little fuel up top (3500 RPM and above).

plugged my car on Star Diagnos to do the -10 fan setting, found out that i can also change the fuel setting from baseline to 93 ocatain which is the maximum, then went for a dyno run...LOST almost 60 RWHP!!! why? attached is the Faults from the SD and my dyno run....man....my car has some proplems....is it the program? should i go back and change the settings to baseline? or should i re-program the ecu? hope one of you guys can help explain whats wrong..

the technician that plugged the Star D did the following:
would these settings conflict will Kleeman Program?
- Ingnition from base to 93 octain.
- mixture from base to slightly enrched.
- fan setting to -10.
would these settings conflict will Kleeman Program?

I know there is a place in Star where you can advance timing +6dg.. I believe that is the function of the Fuel quality (93 octane).. If you change that setting on an already modified ECU (ie. kleemann) you might be advancing the ignition timing too far and causing problems.. I would take the ignition advance off..
I just got my Star working so later today when I have some free time I will be messing around with it on the car to do some "exploring".
The -10 mod is fine but I would mess with fuel or enrichment becaus the kleemann programming already does that.
