2001 mercedes CLK 430 ME2.8 need help :(

[ahmed18881]

i have a problem with timing on a custom file for my 2001 mercedes clk 430 (ME 2.8 ) custom supercharger install , i need to retard timing after 3800 rpm 3 degrees, and one 6 degrees (both partial throttle and WOT). my file was based on high octane fuel which is not available where i live. tried to trick the ECU in many ways but did work out, now driving on octane booster, but still pinging when heat soaked. will send file for who is willing to help me. thanks all for this great forum.

thank you very very much

here you go the car is a US-Spec CLK430 2001 it has the ME2.8 ECU , it has a motor S500 motor swap and E55 Kompressor supercharger. The car has alot of timing advance at over 3800 rpm, i would like to have two files one with 3 degree retard and one with 6 degree retard. Also at partial throttle it has lot of timing if you can please edit both the timing tables in WOT and partial load.

again many many thanks

Try adujusting the fuel air mixture 1/2 turn clockwise, which is a 5mm allen key ontop of the CIS unit.
