LS Swap PCM PROGRAMMING - Everything You Need To Know! + BONUS 4.3 V6 TEARDOWN - UTX 

New drinking game. Have a drink everytime she says “yep” 🥂

I love the way that you explain it so everyone can understand. Very informative!

Excellent breakdown... I even took notes... I am sharing this video on my FB page stat❤😍

you guys are so awesome!! hopefully starting my first LS swap next week!

That impact is a classic😀. Oh and I don't know about everyone else but a quick rundown on your shop heating system is always good content to me.

Thanks for another great video in this series! I glad you said something about the air filter location. Otherwise, I would have made that mistake.

Thank you guys, that was so well done.

Ripley says, " dang dad 40 minutes later to throw a flipping Frisbee for Doggo " May you all have a happy and blessed Happy Thanksgiving. Jerry, Emily, Ripley and Juice. Thank you for bringing us into your lives and shop. I had a life and a shop and Covid took her away. T.S. RACING

Professor Jerry never disappoints

Ok so. I am watching you guys

Happy Thanksgiving to you guys love from Nebraska!!

Awesome series, I'm in the middle of an LS swap, first time, great info. Looking forward to the rest of the videos.

What a great video! Thank you.

Beautiful truck!

One of our service trucks did that same break.

Such great info guys. This will be a great video for your channel. I actually watched your older videos to do my build. You and your wife have been very helpful. I did have an issue come up recently. I had a hard start issue and got a cam position low voltage code. Initially I installed a new Delco cam sensor and just added a new pigtail at the sensor. I am taking it in but wanted to know if you ran into this? This engine is super grounded. Any thoughts? Thanks

Loving your channel, what about just switching to stand alone systems instead of factory ECM and deleting VATS etc?

Enjoying your channel. This one especially to help me understand LS swap, the electronic side. BTW I had a 4.3 with 250k break the crank in the same place. Hm. Maybe a common place?

outstanding thank you

Great video and good information. I just sent my ECM out to a tuner for my LS Swap. I want to run a classic intake manifold and will be doing a MAF Delete. Tuner recommended a Speed Density Tune and adding a IAT sensor to the mix. I'm hoping it runs fine, worried a little without a MAF. I'm keeping my fingers crossed, wish me luck!

Very informative videos there guys! I'll be putting an LQ4 with a 4L80e on my hobby 2000 Astro Van in a couple months, any additional advice and prayers would be appreciated 😅

Love your video's just wondering about with a LS swap if we can use the 01 gauge cluster & how to hook it up!

Hoping to re-flash and tune my 2001 Isuzu Rodeo ECU, after making sure I get a full read of it for later inspection; because it's a P01 that uses a 58x sensor. Be great to have one drive by cable ECU that can do distributors, 24x, and 58x. 58x trigger wheels are used on a lot of vehicles from many brands too, so almost as useful as some holley or megasquirt ECUs. I'm impatiently waiting for the delivery.

The intakes are the same. Its the fuel rails that are different height from LM7 or L59. Swapped them many times

To the question of will he notice the difference between a 4.3l and a 6.0: my friend and I have nearly identical 2002 and 2003 chevy 1500HDs. He pulled up next to a friend of his with a pretty decent freshened 69 or 70 mustang 289 w/ automatic. The completely stock pickup took the mustang by a full vehicle length over about 120 feet. Plus I’ve pulled 20,000lbs with mine. Did 70 mph easily for several hundred miles, I didn’t pass many fuel stops, but essentially trouble free for the entire trip. 😂 keep up the good work! BTW: any more giveaways planned?

THANKS SO MUCH FOR YOUR ASNWER, i GET YOU.

Nice

New sub here, Love the channel, do you have a video on your oil heater?

Awesome video, very informative. Do you have anyone in mind that i might be able to send my ecu to? Thanks

The crankshaft is a common failure point on those older V6s. They were not forged

most people ls swap into a 88-98 truck, OBS, any videos on that style truck?

Do my own with HP Tuners or my Autel IM608. Much better performance without the MAF when tuned properly and takes vacuum leaks, bad MAF etc out of the equation

Couldn't you get away from deleting vats by using the column and bcm from the donor vehicle?

I have a 2010 jeep jk putting a 5.3 Ls out of a 09 tahoe what pcm do I need and do I need the 09 tahoe peddle

Do I have to get ecm programmed if I do a stock rebuild on same engine

how many times does she say "Yeah". or "YUP"..LOL. Great Vids!!

My truck was recently struck by lightning and bought used ecm just wondering if ecm has to match bcm cause bcm got hit as well they sell them already vin programmed just wondering if I have to program to truck vin or new used ecm vin thanks 🙏 for any help

Do you guys prefer drive by wire or drive by cable and if so why would you choose one over the other?

thanx for offer on 3 cyl crank, but the one in my CHEVY METRO is fine, burnt couple valves is all...ez fix only having 3 intake 3 exhaust valves and 3 pistons...although it does have 395K miles on engine, still running, just very rough. was still getting 43mpg highway, 51 when it was new. Q on LS -CPU 5.3 SWAP INTO '81 C-10 Is factory tune from donor adequate/ sufficient to run manual tranny? not building drag truck, will buck n stumble threw shifts until 55mph? does anyone you know have a generic tune for a good starting point ? to be a basic / efficient tune ? motor Q. how bad does oil pan hang below crossmember? is it a must replace? will oil pan from a car a better/cheaper fit than aftermarket ? anything i can do now to remove fuel from injectors as this is a one year project or until needed parts have been allocated ...dont to deal with gummed up injectors after fuel sitting that long...wat are reasonable fees for modifying cpu? i'm still going thru ur vids n taking notes. possible to consolidate a video for.. must have swapping parts... to need to change parts/gaskets...i only ask cuz i really want this swap to be as quick n simple n low budget n satis-factory . this cud be very lucrative in my area . nice abundance of LS engines, not so much qualified cpu tuners tho...maybe simple Q n A video? a sitdown or Live LS square body do's n don'ts with some of your fans like myself, ...N E thots?

Unfortunately being in California I have to have my 85 c10 smog like it is the 2003 escalade I got the engine from which requires literally all smog equipment the caddy came with...lame I know but it can be done

Can u program a computer to fit in 86k5 blazer????

Didn't tack weld the pick up tube to the oil pump. Busted crank is a common issue on 4.3L too much RPM 😂

I wanted your opinion. I go for ugly on outside of vehicle then nice & pretty on inside. I call it ghetto camo do you agree it is natural deterrent of thieves.

What price you guys charge to swap my 2005 Chevy 4.3 l used engine from Yonkers

Great tips guys! Getting ready to pull the tired 350 TBI and 3spd from my ‘87 3/4T Scottsdale 4x4. Donor is a 6.0L 4L65 from 2007 Silverado 2500. Complete with wire harness, PCM, and pedal. Question…how did you connect the shift linkage to the new trans? And cruise control…how did you connect that? Running stock/refreshed 87 gauges with Tach option from LMC Truck. Thanks!

What computer do I need for OBS manual transmission?

do you guys have the videos set up in a series...beginning to end for the swap.

I’m using a 58x e38 ecu and 4l80e t42 tcm. Can’t get 4th gear/overdrive even after changing transmissions. Checked all wiring, any ideas what to look for next?

Yeah 🎉

Hello, how are you? I hope very well, could you please send me the electrical diagrams to make a swap from LT1 Chebrolet to a Chevelle 71. I will be very grateful for this great help from you. Thank you very much.

Yup

So where does a person send the computer to be reset?

Where do u send your computers

Anyone recommend a reputable place to send the PCM out to? 6.0L LQ9 completely stock.

Good evening how's it going

👌🏽👌🏽👌🏽👌🏽👌🏽thanks

Been living on your channel.I am doing a 5.3 ls from a 2006 chev avalanche into my 1985 Silverado.I am using the 700r4trans.have the 5.3 in bolted to trans.purchased motor mounts for the 5.3 that can slide. The driver side fits good the passenger side fits but the mount on the frame is in the way for the ac to bolt in even if I do your mount you did.can not get to the back bolts on the block mount on frame is over those.my truck had a 6.2 diesel.can I move that mount back or what?

For Sale... A one off Bow Tie V Twin engine kit.. All offers considered.

So do you usually go with the no PRND programming option, relying on the hardware switch and relay. Finally approaching the point of putting a P59 on an HSK845 snowblower engine. Yes seriously.

Can I make my factory wire harness which is green and blue with fuse box make it dbc instead of dbw please can you both help me thanks

6:50 going MAFless is known as running in speed density. It is largely based on the MAP sensor tables, I think.

What if the computer , motor and fuse box is all from the same donor truck, everything, Do I still need to program the computer? Apart from deleting the bats

Runs off the map sensor.

Yep! 😂

Long story short I use my hp tuner and turn off vats and rear o2’s. And anything else I don’t need. I don’t send anything out to anyone

Watch this video, but start from the beginning counting the number of times she and he says yeah, yes, and yep.

Please take no offense but what is up with you always saying Yep,Ya,Yep after everthing he says? in this video I counted you saying Yep,Ya 116 times, Its funny and cute but you dont need to say it all the time after he is done just throw in a little more knowledge on the product if anything thats all but love what you guys are doing makes it so much easier to do the swap. keep up the good work.

I wish she wasn’t standing there saying yup after everything you say.

How many times can she say ya/yep its freaking ANNOYING

I REALLY wanted to listen but after the 63th "yup" I couldn't take it anymore.

Yup….yup…..yup…..yup….yup. Kinda distracting.

I absoltely love your videos but the repeaded "yeah" or "yeaps" from the young lady is super distracting and don't add to the content. At the 6:06 mark I counted 40 "yeaps" and stopped counting. I know that I'm being picky but when you have such great content, its the small things make it that much better. Despite my criticism, please continue to make your content. Thank you.

Cut the "yep, yeah" please.

Great video but does she haaaave to yup, ok, yup ok yup.ok. sooooooo annoying. Just film. Let the man talk geeeeeeez
