Dear all members
I own an slk 200k 2001 with siemens ECU SIM4LE
I have a bigger crank and a smaller kompessor pulley and now I have 10 PSI in the intake manifold (measured with mechanical barometer )
I have also install a wideband O2 sensor to monitor the A/F ratio
The problem is that the A/F ratio is always around 14.5 in the entire rage of the RPMs
I went for ECU tuning with out good results ,the tuner who has tuned successfully many slk?s with Boch ECU?s said that we need a modified (tuned ) map from siemens ecu SIM4LE or the damos in order to check what is more needed
Can someone help??
