Idling Auto Start/Stop Questions

I went to the neighbors today.

He's got an 06 pete with an ISX. It was running when I got there.

Went inside, talked a bit, came out so he could change the oil. It had shut down.

He's an O/O and has owned it for over 5 years. He still has his auto-shutdown in the ECM enabled. Never said a word about it....

I know on my Detroit S60, I can set it for either thing. Shuts down after X time or I can have it keep track of temp and start/stop within the parameters.

I just have it set to run non-stop instead.

 

Heres what you do.Bump the cruise switch and it will remain idling.My trk does it,it shuts off like in 5 minutes.So I hit the cruise an it idles high then stays on.You can hit cruise high then tap it again to lower the cruise and it will still remain idling.

 

It's similar to the ac in your home. You set your desired temp. Once the truck reaches the desired temp, let's say 72 degrees, the truck shuts off. When it senses a 4 degree variance between desired temp and actual temp the truck will start and run until it hits 72 again. It will do this as long as you have the opti idle engaged.

 

USA Truck had that on their trucks, and it did help save fuel but one time it had me believing I had a ghost. It was set to run on temp setting and it was -20 out side and I ended up sweating cause it never shut back down. I got up turn the key off and laid back down. No sooner my head hit my pillow it started back up again I almost ran out of the truck. (Key was in the Off Position)

 

Lmfao I would've been running across the lot in my underwear if that happened.

 

Try this ... It worked when I used to drive for a company .. They had this APU set up.. Do not apply parking brakes .. If you are parked then use trailer brakes ... Because by applying parking brakes the timer starts ... But make sure when you are Boobtail .. Bobtail i meant... Use chokes.... Good luck

 

My prostar has this essentially it is set in the computer what parameters sets it but since my truck has the electric APU with an inverter mine is set on battery voltage. At 12.2 the engine will fire up run for an hour and shutdown to charge battery's for continued use

Yeah it's a good feature and from what I've seen it has no triggers to disable automatically unless it jumps when starting signaling in gear
OR when you physicly turn the key to turn it on. My truck will cycle through on off on off every so often even with no key

Some companies program trucks to run continuous after a certian temp is met. Back in college during the corse on ecm programing we were shown how to set a truck to start itself with no key at certian Temps to maintain engine temp for coolant and oil. They do have a "Deadman switch" so to speak. If they sense movement they auto kill to prevent things like starting in gear then the system remains disabled until late next key cycle

 

The Volvo's auto idling when you are on cruise and flat land also on grades. It will then shift to the gear needed for the road.
