Mercedes benz 1991 300ce(RIP), now an 89 300ce
bjay, where is it located on the 89? i knew where it was on my 91, but havent checked on my 89, so i dont know if its in the same spot. thanks

That's borderline placebo. Numbers don't lie, but the fuel gauge is notoriously inaccurate. The only true measure of gas mileage is an average over three fillups, not "I drove ___ miles until the gauge read half full with a __ capacity tank." An average over three fillups are the only numbers I will recognize.

mine was actually sitting right under the brake fluid resivoir.I think its usually tieds to the ac hose.Mine was not, it was just sitting there.

I tell you what. Take that resistor out, pop in some 108 octance boost and you have what some call a quick car. I love it.

Quite a few:)
On the dyno w/ the 560's I've seen as much as 8hp over out baseline up to 2500RPM w/ said resistor pulled. Hell Mercedes flat out says that the stock US resistor causes 'decreased performance and economy'.
Now I do recommend that ya'll check your timing as you may be over advancing on some engines w/ the resistor pulled while others come right into spec.
Here is what I have for timing maps and their resistance:
0 - 145 ohms ~4atdc
150 - 330 ~0 tdc
350 - 675 ~4btdc
680 - 3.0k ~10btdc
3.2k - 0pen ~15btdc
This was off of a 420SEL which should translate to and CIS E car.
The 12 degrees is where the Euro's come set, and that's the theoretical ideal thus it's where I shoot for.
If y'all don't think going from 2-3 degrees initial to 10-12 makes a difference get into an older points car and retard and advance it accordingly...You'll notice the difference straight away.

ha ha, this is all so confusing to me. Luckily, if Matt is correct, my M104 doesn't have this part... So there's no point for me to dwell on it. lol

Love the info. So when you say open is almost 15btdc is that w/out the resistor? I am running high octane and have no pings, i'll check the timing tomorrow. But I could always run to radio shack and get a resistor and solder it in there and check for a varying in perf. "over advancing"? 15btdc is pretty advanced if you ask me. clarify please?!
