reference resistor or R16/1...

hello all. i was wondering if this modification can be done on a 97 C280? "reference resistor or R16/1, it is a manually adjustable dial that allows you to retard your ignition timing" i have a stock C280 but was wondering if this resistor could be removed to improve performance? thanks!

thanks M.B.DOC...

so nothing of the sort can be done on my car? are there any other options for some minor mods for slightly better performance? ie. k&n drop in filter.

As a point of clarification, the USA (and perhaps all of North America) C280 does *not* have a reference resistor, however, European C280's do have the "dial-type".

It is very difficult to retrofit since the leads coming out of the ECU aren't there to "splice" into (I've checked with my 95 C36 ECU & harness vs. the European/Netherlands 95 C36 harness which has the "dial-type" reference resistor).

Not only would you need the Euro wiring harness, but even the ECU may not have this "feature" activated.
