Looking for opinions from those who have them on truck. I don't mind doing the wiring (electrician by trade). Thanks

It probably doesn't help you because it requires the X-monitor to work, but I have BD's Cool Engine Shutdown and I like it. Goes by EGTs instead of a timer

 

I was just on BD's website and it says I can wire the timer to my existing egt probe and I'd be good to go. How does yours work... does it automatically time itself or do you have to push a button every time you leave the truck?

 

It is automatically activated and gets the signal from the X-monitor box. If you want or need to shut the truck off sooner you just hit the brake pedal.

[edit]I just looked on BD's website as well and it looks like their Cool Down Timer works with a normal K-probe[/edit]

 

I have one of these on my truck, simple and effective.

Take a look at SP Diesel's fully adjustable 0-10minute Engine Shutdown Timer http://www.spdiesel.com/shutdown_timer.htm

The great thing about their timer that most the other timers mentioned don't offer is automatic operation. You don't have to arm the timer everytime you go to shut down, that has got to be annoying.

 

SP diesel has a lot of interesting features and I think I may get that timer.... and maybe an eliminator....hehehe.

I've been following this thread......I like the idea of temperature based shut down a little better than time based. If temp is the monster, I'd like to base shut down on temp. I don't have, and don't want, the horsepower boxes however. It seems the BD is temp based, with or without their gauges. Do I have this right?

From what I can tell.... Yes

 

I used to like the temperature idea, but after watching how the preturbo temperatures on my truck behave I really prefer the timer versions now. Depending how I drive the last 30sec of my drive will determine how quick the EGTs come down. Given the same driving style, in one case if I coast into my parking spot EGTs will be at 350 deg almost imeadiatley. Now if I use the accelerator while going into my parking spot the egts will be about 450 and take a minute or so to get to 350. I can't believe the temperature of the oil in the turbo is much different in the two cases I described

Based on that I set my timer between 1 and 5 minutes depending on the time of year and I am always covered. If I am towing a heavy load or on the highway for many miles I may crank it up closer to 10minutes if it is in the middle of summer.

 

So your thinking is not to have the engine run longer than necessary? OR

The EGT may be low enough to shut down, but the oil may be hotter than you want?

I think the second, eh. Good point. I'd rather error on the safe side as I plan to drive my new truck for at least 500k miles!!

I read some time guidlines around here somewhere. Where was that, in some faq?

 

The big reason to use an engine shutdown timer is to give the oil and bearings in the turbo a chance to cool down before oil flow stops. Once oil flow stops if it is to hot, the oil can cook up and overtime distroy the bearings of the turbo. My previous point was that in my experience EGT temps do not seem to be a great indicator on how hot the oil is, at least on my truck, so I use a timer for shutdown.

 

So what I gather from this is I should monitor my oil temp as well... interesting point... now I need another guage.

 

If you could find away to put an oil temp gauge in the turbo oil drain line that would be a real interesting one to watch for shutdown purposes.

 

That wouldn't be too hard to accomplish.
