Idle Tuning Concepts and Some Final Idle Tuning

In this episode I go over the reasons why I changed what I changed in HP Tuners when I was doing my idle tuning after my cam swap in the last video.
I also show how to diagnose what is causing my timing to be different than what is in the base idle timing table, and disable the spark retard that is being caused by the torque management in the tune, which was causing my truck to idle rough in gear due to fluctuating timing.
I think I finally have this thing idling the way I want it to!

WAY under rated channel. Your presentation and demonstration are great. Got my swap idling in no time.

[@LowbuckLS]

john mongrandi thanks sir, I appreciate the compliment and I’m glad you are finding my channel helpful.

[@IsMeAlShOrTy]

Amazing !! Thank you for sharing this information, helped me get my idle right on my truck.

[@n8vjefe]

I greatly appreciate these videos as I am about to dive into the summit 8713 cam and figured I would need a tune based on videos of the 8718 cam at idle. Another person had a tune for that 8718 to idle at 900rpm but didn't talk about anything else as in depth as you. So thank you for showing how to tune it too!

[@chrisnicholson72]

Great video, learned some new tuning stuff off your videos

[@LowbuckLS]

chris nicholson good to hear, thanks for watching!

[@theozman38]

Wow. Someone who explains the why and how. Thanks. Just swapped out my cam in my 5.3 to a sum 8719. Having that bucking at stop and low idle cruising. I Haven’t bought a Hptuner yet but I think tomorrow I will. I hope you can help me with my tuning if I need some, I’m sure I will. Good video

So I've been trying to get the idle figured out in gear. It's taken me over a year to do so and I watch this video one time and learned about the brake trq mgmt. Went straight to it and 0'd it out and it fixed the idle in gear. No more throwing it into second at stops and backing out of the driveway in neutral. I couldn't thank you enough!

[@LowbuckLS]

Trevor Burke great, I’m glad this video was helpful to you, thanks for watching and commenting. Just to let you know, after I made this video, I found a different solution to the “idle in drive” problem that solves the problem without having to zero out your torque management table. This lets you still keep some torque management active during gear shifts. If you’re interested I have a quick video about it here: kzbin.info/www/bejne/pInZZa2oq5uNq7c

[@trevorbmx08]

@@LowbuckLS if thats the one with the brake trq management thats what I 0'd. And i 0'd the 1st 3 blocks of the trq management to help with surging while turning.

Found your channel and really like it. I tried to look at your website for the scanner configs and it appears to not be working. I would like to see a more in depth video on setting up scanner configs, saving multiple configs and using filtering if you know how to do that. That seems to be the most important part of tuning and it is always glossed over. Great content! Keep it up!

[@LowbuckLS]

[@SirHC888]

You will want to find out why the ecm is sensing and looking up the torque management tables before dumping it completely. If it’s just due to the cam, I would update the table accordingly, not completely zero it out.

[@LowbuckLS]

Good advice, and I did exactly that. A couple of videos after this one, I figured out it was the Brake Torque Management setting that was causing my issue idling in drive. Once I changed that setting I was able to put my torque management tables back to factory. You can see the video I did that in here: kzbin.info/www/bejne/pInZZa2oq5uNq7c You’re advice was spot on, thanks for commenting.

can you help?

About to get a hp tune when I put in drive rpm drops 400 then gets back up to around 700

[@redvette2466]

My idle smoothes out to almost no chop when I turn my AC on, what tables can I adjust for that? Also the same thing goes for when I'm in drive but I just figured that to be the stock stall which is about 1800 or is that something I can tweak? Any help would be appreciated.

[@ericdolby1622]

I have a 2003 drive by wire LQ4 in mine. Why is there still adjustment for IAC when I dont even have one?

Good man Randy, i have to say your video's are great, im loving the detail you go into, I've got a cammed 6.0 that has a hanging idle issue,im try the russle k method you did a video on and see if that solves it, what province are you in btw?

Hello, I have the same problem. I dont know what tune i have ! On a cold engine, the engine speed (Idle) is very high at 1800 rpm. I bought the car without a katalysator, DPF and without EGR. I put the Katalysator back in because it was smoking and smells from the exhaust pipe. No errors ! Everything suits me and I don’t want to change anything yet. I just want to change the engine idle setting at startup. How can this be done? Maybe HP Tuner or other tuners ? What do you think about this Thanks 2015 Ram 1500 Ecodiesel .107000 Miles

[@doughooser9708]

Can you make a video of the truck idle outside the truck

[@Euphoria0011]

Still stuck on this 6.1. Wish these crazy idle PID settings didn't exist.

[@CorEdmonds]

Alrighty now, You got that idle sounding sweet! By removing the torque management, will that burn up the transmission?

[@LowbuckLS]

Corey Edmonds the torque management is still active under normal driving conditions, it will still pull timing during the shifts to save the transmission, this just disables the torque management when the brake pedal is pressed so it shouldn’t have much effect on the transmission life.

[@CorEdmonds]

@@LowbuckLS Do you think it was pulling timing in drive do to the higher idle that you commanded? The torque management computer was probably trying to get back to the 550-600 factory idle in drive.

[@justinanderson860]

Hi Randy my name is justin from phx I am so frustrated with tuning my 4.8 L Gen 4 Silverado for Boost I've been built and designed my own rear mount Turbo kit and started trying to tune this thing probably 5 months ago just learning by videos and trial and error and I am to the point where I've had one or two good tunes that we're almost there and then somehow or another I don't save them or I mix them up in a tune and I don't have them anymore so I'm to a point where I have no June at all it will not run is there any way that you can help me out

[@foxlyfe5175]

Appreciate the videos. What did u do with the underspeed table??

[@LowbuckLS]

At the 13 minute and about 15 second mark of this video I showed what I did with the overspeed and underspeed table. Basically I just shifted the table over two cells so it doesn't try and control the idle speed so tightly, it gives it a bit of room to move. kzbin.info/www/bejne/rWe8hXl-abF0o6s

[@ThaProfeshional]

at 23:06 , does that not disable all torque management? obviously that would still fix the idle timing but now you wont have torque management anytime when driving.

[@LowbuckLS]

Yes that did disable all torque management. I later decided that wasn’t a great idea and put that table back to stock when I discovered I could disable brake torque management which only disables torque management when your foot is on the brake. I explain that in a later video I think.

[@lloyddecker2965]

Can I ask u done need to be hooked to internet when tunning the truck ?and what hp tuner do u have ? Some say u only need internet to download hp and stock tune ? Thank u Lloyd

[@LowbuckLS]

Lloyd Decker no you don’t need an internet connection while tuning, I’ve got the old MVPI model which isn’t available any more.

[@Nutflame55]

can u send me your all your channel layout and graph layout u make it look easy.

[@smg8498]

i wonder if the torque management was retarding timing because it was initially configured for a low stall speed converter so it doesn't push the vehicle with a higher idle

[@ktcarroll4723]

My ls 5.3 is 95% done in my 84 c10 it’s running with stock exhaust manifolds open to and tune off of eBay just wondering if I should buy a hp tuner or have a professional do it. I love the thought of doing it myself Waiting on headers transmission torque this week and I can let it run longer and get the bugs out

[@LowbuckLS]

Kt Carroll I like having the ability to make changes to the tune myself so I’m learning HP Tuners. Also allows me to tune future vehicles with the same interface. It is a little complicated to learn though.

[@ktcarroll4723]

Lowbuck LS what hp tuner are you using? I seen one at summit for 299 no credits but reading on websites they say you really need that sensor for exhaust pipe to read the exhaust out put rich/ lean? I’ve worked on cars for 40 yrs but tuning a ecu is a little different than a Holley 750

[@LowbuckLS]

I’m using an older model, the original MPVI Standard not the MPVI2. The one for 299 should work but you will need a couple credits. I made a video a while back showing how to connect and log the wideband O2 exhaust sensor you are talking about by wiring it in to the EGR circuit of the truck, you can find that video here: kzbin.info/www/bejne/hHXcmqRpdpqAf8U

[@ktcarroll4723]

Lowbuck LS thanks for the info. I think I’m going to go for it and keep educating myself with all the videos. Since I’m in a no inspection state I deleted all that egr stuff and depinned the ecu to basically a stand alone wiring harness anything not needed was eliminated. Thanks again

[@calvin4374]

I have a similar build with a slightly larger cam. Idle is tricky, I am also experiencing a slight wandering on start up and stabilizes after a about ten seconds. A process on the that correction would be helpful.

[@LowbuckLS]

Calvin if I figure out how to fix it on my truck I’ll post a video of the process I used, for sure.

[@calvin4374]

Lowbuck LS I made a channels config that has all the timing pids. After watching your video, I made one like yours and it is seriously helpful. My slight wandering on cold start up is visible! My Startup Retard is pulling a bunch of timing. I am gonna figure out which table Startup Retard is referencing and adjust that. I’ll keep you posted.

[@LowbuckLS]

Calvin that great, glad you’re getting it figured out! I’ll have to check that on mine during startup.

[@dudemcgee256]

Your audio gets fuzzy because everything is louder in the truck which causes the mic to "clip". Meaning the sound level is too high for the mic to handle so it distorts. If you have the ability, turn down the input, or you can add a compressor to tame the peaks. Not sure what your setup is, but there is a few things you can do to help.

[@LowbuckLS]

Dude McGee yeah I’m just using a small mic that clips on to my shirt that is plugged in to my iPhone for audio so don’t really have any way of adjusting levels. Works ok in quiet environments but yeah the audio isn’t great in a noisy environment. May look at getting a different set up soon.
