ECU reset = more power,better shifts
Good replies from the E55,E500,CLK55,CL600,etc.... I didnt see any CLK500/209's over there. Anyone willing to try this on the w209 clk500 and get back to us.

I'm concerned about that as well. It took me like a whole day setting up and storing my seats/mirror settings. I don't want to have to go through that again.

The procedure is just to reset your thottle/MAf not the ECU where all setting memories is lost. Only worry if you ever disconnect the battery.

Yes, it does work on mine CL 55 and Clk 500. I also try it with my Sprint booster installed and it didn't work well with the Sprint booster. I have to remove the Sprint booster then put it back after the adaptation is done.

Sorry, but you are wrong. Go back and read pages 3, 4, 8, 12 very carefully. Its a small percentage, but........... It was mentioned

Yeah... it took some digging into. I was intrigued, so I read the entire post to get as much info as possible and that's rare for me
It's to go fast!

Actually tried this yesterday. Initial impression was the car seemed a bit peppier right after the reset. It pulled hard but that could also be due to the tranny shifting at higher rpms than before. I haven't played with the memory functions yet but my side view mirror still adjusted back down to my setting when doing a reverse. I'll check and see later if my memory functions stayed the same. I'd also like to add that I do baby my car when I drive it so I really can't do a fair comparison because yesterday was only one of few times that I've mashed the gas pedal to the floor .
Now am I supposed to drive it like I stole it for a few miles in order for the ECU to adjust?

I tried this and it works. Nothing else was damaged during the process. I got a new tranny and torque converter last week after mine went bonkers and I can definitely say the downshifts are a lot quicker and the tranny always wants to goto red line. I am assuming whichever mbenz tech put in my new tranny, drove it slowly through the gears while they were test driving it to make sure there were no problems...

I swapped my OEMs with a forum member, the tint is only around the outer part, it's spray painted @ medium. Also using silver colored turn signal bulbs from Sixity Inc to complete the clear look.

!! It made the car lower than any installed H&R springs would haha. But soon enough I'll give up and follow the crowd.
