it doesent help out with starting, it just raises the idle speed to prevent washing the cylinders when idling a long time and i can be turned up to help warm up the truck faster when it cold.

When the switch it flipped on it actually decreases performance. it acts like a valet switch. thats why some people mount it out of sight.

no problem with remote start. i got a PPE one but u can make ur own for like 10 bucks.

tomc983 01-19-2009 03:09 PM

oh okay. well seems kinda like a waste. i mean my truck heats up fine and i don't let anybody drive my truck. and it never idles for a long time. conclusion: i don't need it:ok1:

works good in the summer to cool off the truck and also when jumping people with dead batteries.

i use it frequently, but its damn near impossible to have a conversation next to my truck with high idle on

tomc983 01-19-2009 08:49 PM

yeah thats all im really lookin for i work about a mile from home so when i let it run in the am before i leave would like to have it on high idle. the only other thing is if i get remote start woner if i can get it programed that it kicks on

2500HeavyDuty 01-19-2009 09:37 PM

you can leave the switch on the night before, so in the mornin when u remote start it itl be high idling

tomc983 01-20-2009 10:41 AM

i didnt know if that would hurt it but thanks man

Duramax03 01-27-2009 07:41 PM

ppe has one, ask the vendors for one in the price quote forum they can hook ya up

mossburger 01-30-2009 03:25 PM

my 01 has a factory pto switch. that allows it to have a standby at 900 rpm(i think thats perfect) and also a 1250. my 02 didnt have the program in the tcm for it, it just has the 1250 and 1700rpm.

2500HeavyDuty 01-30-2009 07:57 PM

mine has 800, 1200, and 1800 idle speeds, all controlled by the cruise control

My boss has an 04 lb7 and gets jealous everytime my truck starts idling up on its on and he keeps telling me i need to figure out how to get his to do it. Is there a DIY kit or is it something that you have to buy a kit? Thanks

2500HeavyDuty 12-09-2009 01:14 PM

you can make your own swtich, you will need an ecm pin, wire, a switch, and a 12v source

i forget which slot in the ecm you have to put the pin in, ill look it up later.

JTProuhet 12-09-2009 02:53 PM

alright thats cool.. if you find it, hit me up on FB, i will probably forget to check the dmax section.... :moon:

I got mine from PPE (Pacific Performance Engineering). Took 30 mins to install, and works great. Works off the C/C switch. Im in Alaska so its necessary
