warming up / high idle mod

Alright fellas, I got two semi related questions.

I'm one of the unforutnate ones whos parking brake has to be applied for the high idle mod to work. Not sure why some 06 owners don't have to do this, but I do and I don't really want too. So is the computer reading the brake light on the dash for its signal that the e-brake is on? I was thinking about trying to find the feed for that on the e-brake and just hook it up to switch 3 so I can flip 3 & 4 to hit high idle, and not set parking brake. BTW, I did the battery charge route, not PTO. It was simple and only took about 30 minutes to do that and the high beam / fog light mod together. Has anybody ever bypassed the parking brake like I'm thinking of trying?

I was also wondering how much you guys let your trucks warm up? Are you going by timing or ECT/EOT? I used to just wait till my factory ECT gage got up a little. Once I got my Edge I found that to be at about 100-105 degrees. Now I normally warm up to about 105-110 and take off. My truck doesn't have any idle or running issues if I take off cold, but I still warm it up everytime. I'm just wondering how warm people consider warm cuz I'm using a lot of fuel warming up, maybe too much?

Thanks!

i start mine and let it run about 8 to 10 minutes before i leave now that its cold. mine doesnt have a problem taking off cold it just seems like better for the engine to warm up obviously on these cold nights. i havent had any issues.

only thing i have noticed is last year i just had a straight pipe with the cat, this year i am fully straight piped with NO cat and i hear the vanes in the turbo flexing. how often should they flex/exercise when the truck has been running for 8 minutes. and i dont have high idle mod. i let the truck do it by itself

I think it is tied to the dash light. The parking brake is a mechanical brake system so the only electric part you could pull a signal from is the dash light, right?

I put my idle switch on the left side of the steering wheel so I can crank, push my parking brake with my hand and flip the switch without having to get in the truck. The brake doesn't have to be pushed until it is "set", just has to be moved about a half an inch.

That's what I was thinking. Just wondering if anybody has gotten under there, found the wire, and hooked it up.

I also don't normally climb in when I start it. I push the park brake in with my hand like you and reach across to the outfitter switch. Truck is lifted so reaching under steering wheel is easy. My issue is after I get in and situated, I don't want to reach down to release it. I am figity when sitting and have a hard time getting comfortable. I think that's somewhat related to an OCD issue, but that's another story. Then after reaching under the dash to release, I have to start all over trying to get comfortable.


So what temp do you guys with gages normally warm up to?

Man I'm so glad I don't have to apply the parking brake, that would get old quick. I typically let mine warm up about 5 minutes before I get in. I have about a mile and a half drive thru my subdivision afterwards and by the time I get to the main road my temp gauge is starting to rise. Not sure what's on my CS, I'll look next time...

My '05 requires the brake be on but as stated just until the light comes on. Just because I have to ask what is your aversion to putting the brake on?

As you said I bring mine up to about 100 and then go slowly to the end of the neighborhood. Once there I normally have to sit for 10-45 seconds and then I pull out onto the road easy, 35 mph speed limit. By the time I get to the light about a 1/2 mile down the road I'm normally at 130-150 and I roll almost normal. If I really want to smash it I will wait until 180-190.

Have the #3 switch trigger a relay to send a ground to the Parking brake wire. Thats all i did. I even have it where an AUX channel of my Remote Start can trigger it in case i don't want to go out to the vehicle to turn it on or forget to the night before.

Wait now this just got interesting. Please explain? Can you turn your high idle on and off via the remote start?

I use to let it fun for a few min in idle or high idle, but the block heater really helps with cold mornings.

This morning I plugged the block heater in. My Scangauge read 39 degrees.

1 hour later it was 80 degrees.

2 hours later was 94 degrees.

3 hours later it was 103 degrees.

4 hours later it was 110 degrees.

Yes, 39 isn't that cold to start, but was interesting to see that it went from 39 to 80 in an hour.

Currently my oil temp in hour 3 is 77 degrees. It was 40 at starting point.

Oil temp after 4 hours is 91 degrees.
