did this TINY part fix ALL my problems? + 4l80e wiring & tune

- It's a tiny part with huge results! When putting the COPO truck back together after the 4L80e swap I ran into some issues while reconnecting the exhaust which required me to get the welder out. It was a pretty easy problem to fix, and I tried a new part which may have cured a problem I've been battling for a long time with the exhaust. In addition to welding another version of my exhaust, we also took care of the last few changes needed to finish up the 4l60 to 4l80e swap like wiring, and a segment swap in the tune.

We just got the driveshafts back and some more drumsticks, so test drive will be coming up very soon!
And of those items the most important one is the drumsticks.
Did you solders in those wires or just used crimp connectors?
The copo truck is literally my dream truck!!
Do you know anyone in the SLC area that does code removal??
You should make some removable test pipes. I think those cats are killing your power on top
@@dadeftones7 naw fam, the cats aren’t hurting a thing. Plenty of street cars out there making way more power with cats installed. Being on E85 is good. Maybe run E90. Spray M1 pre blower snout; it’s an oxygenated fuel, it has an evaporative cooling effect on the internal parts of the blower and the intake air charge, plus it helps seal the rotors to the case. Lastly, he could re do the ATW system for the blower. Capacity and flow rate is key. I would use a 5-8 gallon fuel cell as a water tank. Use -10 to -14 lines, and the highest flowing pump he can find. Insulate the tank and supply line, fill that tank with as much ice as possible, then top it off with water. Between these mods; your IATs will be well below ambient at the start of a run, and will continue to drop through the run. This allows for more fuel to be burned, more power made. If you start to run out of fuel system, I spray more M1 to supplement the fuel system.
Funny....I just can't figure out why, but I feel like I'm watching a TV show 🤔
🤣😂🤣 Another bang up job LT Love this channel!
lol... I watched powerblock as a kid, I must've taken inspiration from them or something
@@LawrenceTolman Had to be 🤣🤣
Lt..everyone is wondering..although I don't believe anyone has asked. When are you going to change those yellow headlights?? Lol..it is an absolutely beautiful and amazing truck and really deserves some new ones. Keep up the great work. I comment from time to time but I've been watching you since your first day on trucks. Honestly can't believe I can can actually comment and ask you about stuff. Seems unreal. Love what you do. Just like everyone else. On your back,getting dirty, and using what resources are needed and available. I'm almost 34 years old and you are like my role model
I do need to fix those headlights in the worst way, but I'll admit they're at the bottom of my to-do list lol... thanks for the kind words and for watching as well!
I LOVE how much effort you've put in to perfecting the exhaust on this truck.
Great news about drive shafts coming in. Can’t wait to see the test drive and how the new tune runs. EXCELLENT!!!
Whoever has followed you for a little while knows that you LOVE welding mufflers!!! What can I say, you're freaking awesome at it!!!🤙
I appreciate that! and for sure, its my very favorite thing to build or add
Love watching you work, LT, especially fabricating and TIG welding exhausts. I'd love to install a remote turbo on my 2nd gen Tacoma one day. I could really use your fabrication skills!
Great to see the channel grow! Thanks for your time and the content!
Much appreciated!
Another great video LT!!
Dang LT, you tig weld faster than I mig weld! Lol looking good!
got that 1,000% timelapse going in my favor lol
Definitely ready for more big block stuff
that'll be up next I believe
Used many a v band in the USAF on jet engines. We had these cool quick disconnect vbands that needed to be safety wired. They looked so trick when done correctly.
Everything in the Air Force has to be safety wired.
Been there did that on the F-16 and I was Avionics (Helping Engine Troops)

Thanks for another great video.
Truly a truck wizard at work, amazing DR LT..I can't work on anything without my headlamp.. please do me a favor and where safety glasses under truck, a small spec of rust fell in my eye., seen DR they have to scrape your eye no fun looking like a pirate for a few weeks painful and costly,,I like the direction you are going with the super mighty mouse
5:20 yup! Ya gotta clean up your welds. It was my job as a kid to brush all the welds and lightly spray them with a neutralizer
Looking back I’d almost wish that I would’ve done something like this to my 99 sierra, but having probably one of if not the only gen v swapped gmt800 trucks is nice
I had drone in my 86 Mustang the way I got rid of it I purchased a set of DynoMax VT mufflers. They no longer make them due to the spring breaking, so far mine are still good. GM also did kind of the same thing with a spring loaded valve behind the muffler which helps with drone also.
I just did a 4.3 to 5.3 swap in my v6 silverado... I did longtubes to 3" y pipe with a kooks high flow cat and then flex pipe before the 14" magnaflow Muffler.. it sounds amazing compared to by built gmc sierra. One has 14" magnaflow and kooks cat. The other (gmc) had an 18" magnaflow kooks cat and vibrant resonator and it's louder that the chevy and has an extra resonator... I think your onto something LT as I could them to tame down exhaust noise. Especially with headers and camshaft. Good stuff bro and nice welding
Very cool LT
1st thing I’m betting on is you’ll be awake at 2am unable to sleep and you’ll be reconfiguring the exhaust.
2nd you’ll check the fridge for drumsticks before starting any projects
Just for information purposes they are on sale by my place in Ontario Canada this week lol
Love this build LT if you didn’t know what was under the hood you’d never suspect it, it looks completely stock beautiful job
Stainless is an alloy of steel nickel and chrome I believe, the welding process boils out the the heterogeneous mixture exposing more of the steel to the atmosphere. Removing the top layer by abrading it or with acid returns it to a more heterogeneous state.
doing a 4l80 in mine right now too
Absolutely love the real world content of your channel. I’m really interested in the idle drone issue. My 6.0 drones awfully bad at idle, and has long tubes into dual 3” exhaust. Plz keep us up to date as always!
Appreciated! Will for sure keep you updated
3" may be too much
Although u can work with what u have and fix it
one thing i would have liked. Is a brief explanation of the wires being moved. Maybe an edit magic of inserting a pic from the internet. Just to help illistrate what you moved around as far as wiring. And why. I have considered doing this swap in the past. So im curious. 😅
Sweet, let's go!!!!
Good video
Out of drumsticks! Time to visit the supermarket before wrapping up wiring changes.
Wished mine was 4wd, good job dude.
Thanks!
Good man, crimp and heat shrink! 😆
Keep up the good work.
Thanks! Will do!
I love the fact I can still learn by watching your videos. I just completed a 4l80 swap on my 08 Tahoe and ended up using the pcm of North Carolina harness because I didn’t trust the limited info I could find on the tcm side on my newer vehicle. Do you know of any channels that cover that new wiring well. Thanks for all your great videos.
I'm looking to do an e fan conversion already upgrade rad. Plan to use pcmofnc as well.
If your experimenting with mufflers it would be awesome to hear how a Gibson exhaust sounds with your build.
I had the Gibson super truck exhaust in my 01 Silverado.
I would be tempted to place a heat shield or wrap onto the exhaust section which is closest to the transmission pan.
Drumstick withdraws!😂
oh don't worry, I got more already
Yes sir 🔥🔥🔥
Awesome build as always. In the future before you pull off the LSA. Have it ported and run the same pulleys. I bet the truck will be much quicker just being more efficient.
Port blower and snout. Your effectively increasing the displacement of the blower. Also, spraying methanol pre blower cools intake air temps while adding supplement fuel and helps seal the lobes/rotors to the case. You can gain 1-2 psi of boost by just doing this
You should header wrap your new crossover pipe and keep the heat out of the trans pan!
How do you like the forney tig. I bought the 420acdc but we moved and I haven't ran an outlet for a welder yet so haven't gotten to try it out.
Have you considered getting a magnification lens for your welding helmet?
I noticed you were almost touching your work piece with the lens.
Do you have a link to the bluecat trans tool ? Every time I try one the links don’t work thank you love the content
I fuckinhng love this sorrow for my language. Building or should I say rebuild my own lq4 chevy. I've learned so much Master lol hope all is good 👍
all is good, and thanks for the kind words! much appreciated
You should get you a mini split AC in there. I got them in my shop, they’re awesome, quiet and take very little power, installed myself and best part they were cheap.
That sounds like an awesome idea.
Heard 4L80E takes 30% of hp . Hope you do another dyno pull n tune to see if this is true 🤷🏼♂️😎
I have no comparison but I have a 5.3 4l80 el Camino with a cam and comparing draggy times to what power I should be making it definitely is soaking up some power. As well as the 9 inch rear I put in. But as with lt it’s all for strength when I’m turbo it will hold up.
It does soak up more power, but it’s due to how much more the spinning components internal to the transmission weigh when compared to the 60E.

You talk about a low frequency drone even at idle. I had a very bad issue with that with my LQ9. Turns out it was due to having my muffler too close to the end of the exhaust. Someone called it "muffler echo" and I ended up finding a patent that referenced the issue. Patent # US4501341A if you care to read through it. Here is the section that breaks down the issue. I found that less muffler actually made for a more tolerable exhaust.
"A problem faces the designer of a muffler for a motor vehicle, where the muffler had to, of necessity, be located behind the rear pair of wheels (or behind the rear axle) with a consequentially short tailpipe. In order to silence high frequencies other designers invariably specified a large muffler volume, with a large acoustic compliance, and with internal devices such as a perforated main flow conduit which have a low acoustical inertance at low frequencies and a high inertance at high frequency. Such an arrangement is satisfactory at high frequencies (over approximately 1000 Hz), however, the compliance of the muffler volume is in resonance with the inertance of the gas in the short tailpipe at a particular low frequency, usually in the range 30 to 100 Hz with typical dimensions in practical use. There is thus a frequency range, centred about this resonance for which the insertion loss becomes very poor and the radiated exhaust noise becomes high.
An obvious solution to the problem is to increase the tailpipe length considerably to increase the tailpipe inertance and thereby place the problem resonance well below the operating range of frequencies."
Basically it means the correct Size of the exhaust system and correct distance and baffles in the muffler.
@@shadowopsairman1583 Uhh, of course. Everything should always be correct.
Shorten and balanced drive shaft will be nice.
Flex pipes definitely help over all.
They don't look bad.
Can't wait to see copo on the road.
Be safe.
Put a wet piece of cloat around the flex material. If a welding spatter gets on it it might break.
With big bore exhausts in my experience there is only one way to fully eliminate drone and that is with glass filled mufflers.
At what point are you going to install v bands on the muffler since you change it out so much? like on either side of the muffler so its super simple and small to install and remove
you work very nice and security thumps up,alot work without safety glass,glove or ear plug,
Good job,il your 60ft is less,put nitrous on ;)
Thanks 👍
How did you go about finding the correct OS for your pcm. I have looked for a while and have had a hard time doing so.
Hey Lawrence any way you’d be able to reflash a 4.3 ecu for me
Change the x pipe run a cts v and do equal length from there thats what northern performance did kinda
that would be awesome to do, but the AWD system makes packaging a symmetrical exhaust a challenge.
I believe that's why they say it's good for turbo because they don't come apart on the inside.
You use the pf61 filter ?
LT does hptuners allow user segment swaps now? It use to be you had to contact hp directly and have them perform the swap and then download to the ecm.
yup, its a tool available for users to do on their own, just have to make sure the operating systems are the same from the "donor" tune and your tune
Try black widow mufflers. Their motto is all time and no drone.
Looks good. Get some more ice cream lol
Dose any one know if a 485e has engine braking like a grade shifting my 04 8.1 suburban coast down hill in less manual shifted
Typically those flex couplers have a direction that the flow needs to go. Are yours that way? If they are backwards they can collapse and sling metal down your exhaust. We have something similar on locomotives and they take out the turbo if installed backwards.
there was no directional indication on this kind, but the "bellows" style I have used in my wastegate dump tube on my other truck is directional
👍
Just an observation, but I noticed that you have a nice welding table, but even when you are not clamping the part in the vice, you seem to weld on top of the vice LOL
its at just the right height lol... plus I do need to get some more clamps and fixtures that attach to the welding table to take full advantage of that
Tough break on the drumsticks😔
Did you opt for any gear changes in the tranny itself? Anything to be had there? Corvette or Camaro gears any better?
no, still using the stock 80e ratios, and no real options to change anyhow, except maybe some high-end custom stuff
Hey LT, after the motor mounts, how’s the vibration inside the cab now?
Haven’t driven it yet, but will update in a video once I do drive it
I am curious as well on this one.
How old is the truck tech T- shirt 👕 🤔 lol. P.s. put my ear buds in ( the right way) so wife could watch her show... while I was eating chocolate chunk cookies 🍪... ice cream drum sticks 😋 all the way, j/s. Thanks for the videos LT.
at least two years old lol... just a reminder of the "old days"
What welder is that?
i fuck with this channel
A man has to have his priorities if you want the work done right you need drumsticks in the freezer!
It’s a necessity with these temps
I was curious if the 80e had bigger (diameter) cooler lines. I know there In different locations
nope, same 3/8" diameter lines as the 60e
@@LawrenceTolman ok, I have an 04 escalade I'm thinking of doing the 80e swap
Do u notice more valve train noise with the upgraded cam and higher rate springs?
Oh yeah, lots of clickety clack
@@LawrenceTolman okay good. I used btr torque cam kit and I know the springs were way stiffer than OEM and I got a little more noise.
I was just thinking that on my LS3 with BTR stage 3 cam and springs. Glad I am not that only one hearing that.
Why is the big block not going In the COPO truck!? I don't understand
I should put my spare 8.1 in the AWD truck with a massive Whipple on top
Those flex pipes will fail if there is too much stress on them.
The exhaust mounts need to take all the weight and allow for expansion and contraction.
I’ve seen them fail within a week when poorly fitted holding most of the exhaust up or being too rigidly mounted.
very valid point. luckily my exhaust is mounted in several rubber isolators so the weight is evenly carried and not relying on the flex couplers to hold anything up
I had flex pipes on a 76 chevelle with a 468,and when installing them 5 inches from the headers i also hung the exhaust up with brackets right after in the back of the trans..those flexpipes did their job,and still do 12 years after.Havent changed a exhaust gasket in all those years
@@blazerteam . You did well. I worked as a mechanic in an exhaust shop for a few years and often replaced flex pipes even on factory systems, some still under warranty.
Call it the COPO-RADO
If you want to eliminate drone you need to change the length.
Someone get this man a drumstick asap
You need a lift LT
have you tried the dynomax ultra flo muffler?
nope, never tried an Ultraflo, but have heard good things about em
@@LawrenceTolman I had one on my Rex with a Vibrant resonator 3" all the way and it really cleaned up the exhaust note. Only reason i changed it was because I got a valved muffler for loud or quite.
When you said "drumsticks", I instantly thought of "drumbeats" and this channel: czcams.com/video/q8JRL5kKhHw/video.html
Yeah, when you run out of mojo sticks, it's time for a road trip!
Hey LT, What Vice is that on the work bench?
its actually a Wilton trailer hitch vice on a bracket I made
@@LawrenceTolman Got it, that is what I was thinking when i saw it.
Hey! I’m in SLC looking for a tuner that can do code removal, do you know anyone? Or does anyone here know anybody??
What depinning tool do you use for the trucks?
I was able to do both connectors with just a regular pick and small flat blade screwdriver
@@LawrenceTolman OK, do you think you could possible do a tutorial on a few of the more common connectors?
So just out of morbid curiosity, why not do a 6/8L80E swap... best of both worlds, low 1st gear, and the higher ratio OD
Nah... I'd trade 2 drum sticks for an orange creamy. 🤗
that sounds like a fair deal to me
Why don’t you try corsa they sell individual mufflers. I’ve tried so many mufflers and even with cat deletes and resonator delete only corsa removed all drone. It’s a great company.
Where can I get bluecat tool
I downloaded it ages ago and always saved it on my computer, not sure where it can be found now
Oh no! you can’t be out of drumsticks 😭
Thunder bird San Diego Bridge
Are you worried about the fact that the iss is not a twisted pair
that is a valid concern, but the input speed sensor I added to my other truck is not a twisted pair and it seems to be working just fine, so at least for the moment I'd say it will be OK. but time will tell once we go on the test drive.
👍🏻👋👨🔧✔💯
Good exhaust for a Chevy V8 high flow cats y pipe flow master 50hd maybe 70 or 80 series if you want really quiet
Get those drum sticks
Exhaust iteration #157
Surprised you still have the P01 PCM in it and haven't swapped to a P59. If it works then no reason to really do it I guess.
I have a P59 in a box ready to go for Flex/3-bar but so far I haven't exceeded the 2 bar table (we're close) so it hasn't got switched out yet
@@LawrenceTolman gotcha. I have a P59 3bar 80e flex fuel DBC setup in my truck. If you need any help let me know.
Is your garage high enough for a lift? Im gonna start a gofund me....lol
Dont be mad when you hear of a guy in S Carolina has copied your truck right down to the color.... haha (Im kinda serious tho..) Greetings from the farm in S Carolina!!
hey, copy away, I think the orange is a cool color. Unfortunately my ceiling has a major structural beam right in the center which would prevent any kind of usable height on a lift, but someday we'll get into a proper shop
@lawrence LT Tolman. do you think there will be much of a difference in acceleration since the 4l80 has a taller 1st gear compared to the 4l60
there will probably be some difference, but hopefully the better torque converter will help offset that. we will be doing testing to confirm though
butyl mats on the rear wall and the floor... will make that drone disappear. keep in mind you don't have to cover the entire surface 100% to make it effective
All this complicated computer crap 😆 im screwed if I ever make the jump into the new age technology lol I'm still stuck in the sbc/power glide or Th400 era lol and its obvious why I havnt made the jump into the LS/4l80e days. But its sounded better and better, also more confusing the more I watch lmao
Lay off the drumsticks buddy 🤣
Never!
Why are you running cats ?
What good is the footage of the 4l80e wiring swap if you don't show or tell us what pins to rearrange, I watch CZcams videos to learn or for something I'm planning just like this swap, not just for entertainment. I watch so many videos that just waist my time because they don't elaborate or show enough details to get the job done.
I'm sorry LT I guess this isn't meant to be a "how to" video, things just ain't going my way, I hit a deer and totaled my car so I'm pissed at the world.
17:14 holy shit that was complicated just get a manual
