fast idle for 2001
#18
Can the high idle be temp be changed? for instance can I set it to do this if it's colder than 50? or even now when it's 1 if I plug the truck in it doesn't do it. Can it be made to? I use the stick method now, to let it warm up.

Here's what you do. Find your local DTR chapter and join. Then there is bound to be one of the fellow members with the Smarty. Just load it and unload it and BAM, High idle, worked on my 99.
Last week i started the truck in the morn after not being plugged in and walked away, all of a sudden it started to idle up.
the Ebrake has to be on though for it to work.

I think this question is still up in the air and hopefully one Marco will be able to answer.... I think a lot of us would like to see the temperature raised.

I had emailed mads in the past and I think it has been mentioned here many times that this option was not in the plans... So built my own

Wow,
I just started my truck. It was in the teens last night with wind chills in the single digits. High idle and 3 cylinder idle both kicked on. Man does it sound weird when those other 3 cylinders drop off!

TSB says 15F or below, but it's been colder than that, and I've never had the 3 cyl kick in.

1. Intake Manifold Temperature less than 0°C (32°F) and,
2. Coolant Temp is less than 60°C (140°F) and,
3. The Transmission is in Neutral or Park and,
4. The Service Brake pedal is not depressed and,
5. Throttle = 0% and,
6. Vehicle Speed = 0 mph
Additionally, if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters above are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change (yea right!) in engine sound which is normal. This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and cab heating.
Both features will automatically disable when one of the following occurs:
1. The Automatic Transmission is placed in gear (forward or reverse) or,
2. The Service Brake pedal is depressed or,
3. Throttle position is greater than 0% or,
4. Vehicle Speed is greater than 0 mph or,
5. Coolant Temperature is greater than 79°C (175°F).
Engine speed will return to normal operation at 800 rpm. If the engine continues to idle and coolant temperature is at or below 60°C (140°'F), the feature will reenable. In order to operate properly, the Accelerator Pedal Position Sensor (APPS) must stay at idle.

The kicker here is the intake air temp which is located after the intercooler. The air is one getting heated by the turbo while it's being compressed and two the grid heaters keep cycling on and off which is heating the incoming air as well. That's why I built my own little high idler. It works like a charm. I love this thing.

try a diesel speciality mechanic or a cummins dealer. we have a place here in anchorage called northwest cummins. They might have a location in canada Sadly Ive found that most dealerships dont have much of a clue when it comes to diesels.
