has anyone tried to mess with the r17/1 on the 300SE? according to alldata, its located on the right side of component compartment, by the battery I suppose, but I am unable to find it. however, there is a R17 trimming plug, located somewhere near the ECU, which I was also unable to find, does this one have the same function as the r17/1? If you have some pics, that would really hit the spot. I have already removed the R16/1 and I like the results, especially above 3k rpm.
