Greg,
Thanks for taking the time to investigate and post these results. Originally, the R16 "mod" was started for the 190E 2.3-16 valve U.S. spec model only...somehow, it got out and everyone with a CIS-E (KE3) equipped engine thought it would increase their performance.
In my U.S. spec, 1987 190E-16V, removing the R16 made a difference only above 3000 RPM and only that the engine revved faster to redline from 3000 RPM on up. Yes, this is by my butt dyno and not verified with actual measurement. I have since acquired a Euro-spec rotary resistor 'switch' and hope to run some tests with a G-Tech accelerometer to verify any improvement
if any with the different resistance values.
But anyway, thanks for posting your results!
