3208NA driving tips
Hey, On our recent trip to Moab (3 passes between here and anything
remotely flat)I recently went into "full fuel" (read:overfuel) mode.
Propane helps when acelerating, but when you get into an overfuel
situation, it seems to have no real benefit. My question is: when
pulling a grade, what driving style do you prefer? As far as going by
the full fuel light, should I back out until it just flickers and have
some popcorn until I reach the top, or just keep pouring the coals to
her (or him as the case may be)? What seems to work best?? Best to all,
Doug n' Pokey.

If you have looked at the circuit, the "Full fuel flow" display just
indicates that the injector pump has hit it's stop and will not flow any
more fuel. You have probably noted that it is a function of RPMs and
throttle position. My cruise control will put it into "Full fuel flow"
rather frequently. If we are maintain speed and temperatures are within
range I don't worry about it.

Doug,
We don't have propane injection nor do we have a full fuel light to watch. We
gained some
hill climbing experience on Monarch Pass last summer that may apply to your
question.
We're normally flat landers by comparison to Colorado so we had a steep learning
curve on
our drive to Ouray. We found that we could overheat the coach fairly easy by
holding the
throttle to the floor for extended periods while the coach gradually lost speed
and bogged
down.

Part of our overheat/boilover problem was a weak spring on the old radiator cap
which
was replaced during the trip. On our trip home to Texas, we experienced less
overheating
by proactively selecting lower gears and accepting slower speeds (say 20-30 mph)
that
could be maintained at something less than full throttle. We've since installed
a switch
that allows us to engage the radiator fan before getting too hot and that is
also helpful.

We recently had the valves adjusted on the 3208 and I've noticed a distinct
improvement
in power. It'll be interesting to see how the coach works the next time we hit
some serious
grade.

Thanks for teh input. Yours being a 84 should be turbo, so there is some
difference there for sure. Best Wishes, Doug n' Pokey

Doug:
I suspect you don't have a pyrometer, but the EGT's are a pretty important
measure in
deciding how hard to push the coach. Last year, when running through the hills
of WV,
the crossover pipe which feeds my aftermarket turbo started to fail, resulting
in lower air
inputs and overfueling. I noticed a marked increase in EGT's to the point that
I was
becoming quite concerned. It was running about 200 degrees hotter than normal.
I would
be concerned that the propane injection might produce a similar result. Without
piston
coolers (which the turbo motor has, but the NA doesn't), this puts the pistons
in danger of
melting.

Kerry,
Thanks for the input. Mine is NA, so no turbo and no pyrometer. To the best
of my knowledge, the propane does not significantly increase the EGT, which can
be a real killer as I'm sure you know. Thanks again, Doug
