Today I did something new: set the injection pump timing on my E300 using
the millivolt method. My goal is to improve fuel consumption.
The glow-plugs will produce a very small voltage when heated, due to the
dissimilar metals used to make them. Measuring this voltage (~12 to 13
millivolts in

Interesting idea. Did you read about it some place, or think it up on
your own?

Indeed we will! I do wonder whether optimizing at idle will yield the
desired results. It all depends on the accuracy of the mechanical advance,
and whether it is even possible to optimize both idel and cruising power in
an analog system.

There is an incredibly long difficult thread on peach parts forum that I read
long ago. I've always wanted to try the method. On that forum, the 123 crowd
found the injection pump nearly impossible to adjust on a running engine n

I timed a couple of 0-60 runs, with full tank of fuel and extra passenger
(daughter), and the car is about half a second faster.
Of course, the timing may have been off before I started this experiment.

Yes, thought about trying that. Would need a long empty flat road, as the
voltage takes a few minutes to stabilize.
In college I had a Datsun B210 or something like that, and set the ignition
timing by field test. Time a 0-60 run, move timing, repeat until fastest time
achieved.

Optimizing for cruising efficiency is the goal, I just may have to repeat and
make adjustment based on measurements at load. Would be nice to have access to
a dyno stand...

Problem with the OM61x engines is the lack of an adjusting mechanism on the
pump to facilitate adjustments on a running engine.

You certainly could monitor the voltage while driving and maybe even rig
up something to make the adjustment, but I think you might want to
monitor other things, too.
Maybe rig some sort of throttle stop so that you could use the exact same
throttle setting on successive runs? I

Attaboy!

Guaranteed if retarding it made an improvement.
Proper facto
So what 0-60 times does Caterpillar attain? ;<)

That's what I thought, too.

Caterpillar has made engines for big trucks for a lot of years.
And they now are selling 'em.
So 0-60 MPH i

604/605/606 are the four valve per cylinder versions of 601/602/603.
I think 606 NA was first introduced to USA in the 1995 W1214.
1990-93 had the turbo 60
Oh yeah. I forgot Max drives a '95.

Factory. Last year of the 124 line got the next generation engine, which was
used until 1999 or so. Non-turbo in my car, was turbo variant in later years.

Bust.
Fuel consumption is slightly worse, probably about 5% or 10% worse, after
about 1500 miles of driving.
Retarding the timing always does that, unless you were seriously overadvanced to
begin with.
Advancing gains MPG at the expense of increased peak cylinder pressures.
