Remote Starter kit for 02 Forester?

[Tony Hwang]

Sounds like a great strategy when an outlet is not available.




My truck (ex-military) has what they call the arctic package. It
has a handheld gas-powered turbine (picture a big leaf blower) which
slides into a fitting under the front bumper. From this fitting,
pipes carry the hot exhaust from the heater around the engine and
the battery box. Once the engine has been warmed up, it can be started.
The heater can then be removed and a nozzle is fitted over the end
and the jet of hot exhaust can be used to de-ice the vehicle. The
heater then slides into a fitting where its exhaust drives a fan that
pulls cold air over its exhaust pipes and into the rear compartment
for heating. It's pretty cool, but I've never actually used it. The
coldest I've ever started the engine was about 5F and I was glad to
have a 24V system.

Hi, Dan
How about -30F without wind chill factor? 5F is short sleeve weather for
us.(little bragging, LOL)
Our life with automobiles got lot easier since the day of electronics
control and fuel injection. Much less starting problem in the winter.

Warm up cycle is computer controlled?
How? What does ECU do for warming up the car?

Everything. In particular, it controls the fuel flow - taking over the
job which used to be done by a manual choke and later by an automatic
choke. The ECU optimises fuel flow to minimise emissions, which are at
their worst when the engine is cold.

My definition of warmed up car is one I can drive off without any
hesitation or jerkiness, or difficulty with shifting gears.
Simply, warmed up car is drivable normally.

Fine. You are welcome to use any definition you like. It won't make
any difference to the ECU, which will decide when your engine is
warmed up to the point where it is working at normal efficiency.

Been driving ~50 years, I never encountered any unusual problem with
cold weather. Today's computer controlled car needs less idle(warm up)
time compared to old carb. engine cars for obvious reason.

Interesting. That appears to be the situation, yes.....probably
because the ECU does such a good job of maintaining driveability
during warm up. Modern, lightweight engines are, of course, designed
to run much hotter than the old cast iron lumps we used to use.

The ECU shutting down a car which has been only partially warmed up
and not allowing it to restart for half and hour or so may not be
common, but it is a well documented problem.

Fact? I have never heard this before and have been driving profesionaly for
23 years.

Try reading, listening and keeping an open mind. It's called
'learning'.

Where do you come up with this stuff?

Hi,
ECU's does not know whether you started the car remotely to warm up or
whatever, It's job is to make engine run for the condition. If it was
cold then it'll deliver more fuel like old choke did, etc. ECU has no
way of knowing this is warm up cycle, so I am doing this. Just it is
doing it's job as programmed for the situation. I neve saw anywhere in
the ECU firmware listing, routine for warm up. There is routine for idle
which has a sub-routine for variuous engine state; cold, hot, humid,
high altitude, low altitude, fuel Octane, etc.
Show me warm up routine in the listing.

Where did I ever say that it did? Go back and read my posts again. Do
try and understand before you start shooting from the hip.

Once again, where did I say you shouldn't? Go back and read my posts.

I would definitely use the artic package or an electric heater if
I lived in a colder climate.

Our life with automobiles got lot easier since the day of electronics
control and fuel injection. Much less starting problem in the winter.
Definitely!

The intended mission of my vehicle is portable communications.
I've restored several of the military antennas but none of
the original radios yet.

David - I think what Tony is taking issue with is your statement: "The
warm-up cycle is computer controlled. If it's not completed to the
satisfaction of the computer it may well not allow the car to start again
for several minutes."

Perhaps this could be cleared up if you would focus on that statement and
elaborate on what you were getting at. It does sound like you were saying
there that the computer could lockout the engine from starting up if it is
cut off in the middle of a warm up cycle - not clear if you would say that
the firmware is intentionally designed to do that, or it's an inadvertent
result of a chain of events not anticipated or compensated for by the
designers (conflicting sensor readings until cooldown occurs or something
of that nature).

I very much suspect the latter, Bill, but I have no detailed knowledge
here.....other than having read reports from reliable sources of a
number of occasions where precisely this set of circumstances has
occurred - a car is started up, driven a short distance, switched off
again and then won't start. Half an hour later it starts as normal.
Diagnostics can find nothing wrong.

Hi,
Then something was not right with the car. ECU stores number of past
incidents in it's memory. You can pull it with diag. tool.
I never had an occasion cold or hot engine won't do a repeated start.
Let's close this thread.

It has always been regarded as bad practice to leave an engine idling
to warm up, though. Much better to drive it gently until the oil is up
to temperature.

David Betts

That's true if you _*don't*_ live in Montana; Alaska; most of Canada; etc.

You'll drive nowhere until you've brought some lukewarm water into the heater
core for the defroster to function.

***There's a reason why Brits say "defogger" and Montanans say "defroster":

After scraping the outside of all the glass and mirrors, brooming off 6" to 2'
of snow, rocking the rig back and forth with your butt and legs to free up the
tire-melt ice to keep from snapping an axle; you'll be breathing enough moisture
to frost the inside of the windows .

That's not even counting the other possibles--- getting the hydraulic clutch to
move; moving the shifter; moving the seatback for a backseat passenger's entry
without cracking the old vinyl upholstery...

Hi,
I call it de icer. And what Brits know? They drive on the wrong side of
the road. Wonder how many Km from one end to the other end of Britain?
I have to drive all day like crazy just to get my daughter's living in
next province. They don't even have a clue how cold it is in winter
here. Who cares about wear and tear, name of the game is start the car
and get moving without freezing to dead.

And all that with no guarantee you'll get any farther than
the end of the streeet.
