My car will soon be turbocharged.  I would like to have a way to program it to turn on and run for 10 or 15 mins at a certain time of the day(ie, before i go to school in the morning and when i get out of school)  I want to do this to make my engine last longer by being properly warmed up before driving.  If anyone has any ideas, please let me know.  I'm thinking all I would need is to output a signal to the ignition and starter to cut on and off quickly, then my turbo timer will make sure it runs for the certain period of time.

Thanks

Sooooo...... you basically want a remote starter then.....

not really, i want it to start up before i'm walking to it.    i'd like it to run for 5 mins before i even rev it past 100 0 rpm. metal expands differently at different temperatures and revving high when it's cold your tolerances are different and the oil doesn't flow as well so your engine is different, if that makes sense. I was told i'd need a microprocessor w/ a built in clock. Maybe this needs to be moved to another forum?
Thanks

so what is a good company that makes them.  i thought remote starter meant that you can start your car from a certain distance away from it, but you had to hit the button yourself, and it's not programmed.  i guess i thought wrong.  thanks

Alright this is gonna be a long post. I think this was the best place to post this, but move it if there's a better place.
Anyways, my car will be turbocharged soon and I would like to make it start and warm up for 10 minutes at certain times of the day. I have been having a hard time getting answers on how to do this so I went to howstuffworks.com and started looking at programming stuff. They skimmed over the basic program and using a stamp module from parallax. They said the stamp is not extremely fast and doesn't hold much memory, but i don't believe i need that much room anyways. I believe all I need to do is have a wire come off of one output on the stamp to send power to the ignition and starter, kinda like an amp turn-on. I think it will only need to stay on for about 5 seconds and then let it shut off because I have a turbo timer that will keep the car running for my set time after it is cut off. The turbo timer will just be preset to run for 10 mins everytime the car turns off.
I think the programming could work something like this if I understood HSW.com correctly:
high 3
pause 1000
low 3
sleep #(# equal to number of seconds until afternoon start up, like 10 hrs)
high 3
pause 1000
low 3
sleep #(# equal to number of second til next morning start up, like 12 hrs)
high 3
pause 1000
low 3
pause #
...etc... you get the point
I know some of the stamp models will only hold 80 commands and i don't think that would be enough to program for a whole week and then tell it to repeat so my last output could go to another stamp to turn it on and have it end the week, then the last output on stamp 2 would turn on stamp 1, etc.
How do you guys think this would work out, maybe I should just get a more expensive stamp that will hold more commands, or are there other chips i could use that would do the same thing and be cheaper. I dont know much at all about programming, but this is valuable to my car as I would like the engine to last as long as possible.
Thanks in advance to any replies
and again sorry for the long post, but i didn't want to leave any questions to ask

Sooo... you want a DEI 611T, and a 130XV.
The 611 is a programmable timer/temp box that can start the car at exactly the same time every day. The 130 is a baseline starter that can be externally pulsed by the 611T and will start the car.
No sense building something that is readily available, reliable, and proven to work.

PS: A 10 min turbo cool down time is waaayyy overkill. 3min, tops, unless you regularily come to a screeching halt after driving at higher than highway speeds for hours at a time. Use a quality synthetic oil, nothing to worry about.

I think you are going at this backwards, typically on a turbo'd car you want it to cool down after you are done driving, warm up can be safely done by driving the car.  If you don't have water cooled turbos (like me!) its a good idea to let the car idle for a few mintues AFTER you are done driving it, to let the oil in the turbos cool.  If your oil heats up and cools down too quickly it can cause problems.

So gus, where can I find the products you mentioned?  And also thanks for continuing to reply and try to help me with this, I know I sound like a total noob.  10 mins was just kinda a rough figure, maybe i'd like about 5 mins warm-up.  The only thing is that on monday and friday I need it to start at 8:05 before I leave for school and then at 1:15 when I leave.  Tuesday and thursday I need 3:35 and 7:15.  Then Wednesday I need 8:05 and 4:30(I have lab this day).  Then saturday and sunday I need 4:00 am when I leave work and 4:00 pm when I go tow work.  So starting at the same time everyday won't work right.  I need something fully programmable for my schedule.  Kevin, I understand the need for proper cool down as the oil can "cake" up in the turbo, that's what I got the turbo timer for.  But metal also expands slightly differently at diff temps.  It is safer for the pistons to be moving at the low velocity of 1000 rpms, rather than being revved to 3 and 4000 rpms right when it's cold.  I want to keep the engine tolerances as small as possible for as long as possible.  I realize that lots of people, almost everybody, just jumps in their car and drives off with the engine cold and some car last over 300,000 miles, but by that time the performance of the engine has decreased by up to 75 percent or somthing I'm just guessing.  Anyways, point is I want my engine to last long and stay as close to it was right after I rebuilt it, even though I may end up rebuilding it after only 50k, when I do I wont have to do much machine work.

That's it, Thanks for the help

I just try to keep my car under 2000RPM until the temp guage is half way up, and definately stay out of the boost.  To me, this just seems much easier then trying to set up what you're going after.

Good luck with your setup, I've seen the DEI timer but I've never used one, I'm not sure how programmable they are.

I have used event timers for work though, and some industrial event timers will let you program on/off points for every day of the year (nice for holidays).  I'm not sure if anyone makes one in a 12vdc version, but that would be pretty cool!
