Budget LS Swap VATS Security Bypass FREE DIY

Budget LS swap, VATS security Bypass no tune required. FREE DIY CPU unlock! How to get your #LsSwap running. No Hp-Tuners, all DIY. Support the channel: 👍🏽💬♥️🔔 Rate, comment & SUBSCRIBE 🙂🛠
In this video we DIY bypass (glitch out) the VATS security system for free on a 4.8 5.3 6.0 gm truck computer using a simple trick, unplugging the BCM while its already running. if it wont run that's ok, we can install your computer into another running vehicle, relearn the key, run it, and then unplug the BCM and confirm it will restart without the BCM.

Dude you get a million likes from me. I have an old spare 1500 I swapped a 6.0 into with the computer and body control module from the donor truck I rolled over and have been wanting to put the whole set up into an 89 S-10 shell I have sitting around but don't want to pay big money so I can do this trick with my original 5.3 computer then take everything out of the 1500. For real thanks. It's just too much beater ass parts and the body of the s-10 for me to spend any money doing it. I also subscribed to. All these know it how channels and you are the one that figured it out mad props.

im glad it helps. yeah every dollar saved counts lol. im not the one who figured it out, im just sharing because when i wanted to figure it out, everyone told me you need a tuner which is $$$, luckily we got it figured without any tuners or any money spent. maybe later i will get a performance tube but im happy to have it running for now. thanks :)

[@613Builds]

Ryan MacEwen thank you sir. I just went for a drive in the car today. I think I’m going to mess around a bit with side pipes and maybe free tuning software also. More to come soon, maybe a posi, definitely needs a posi

[@ryanmacewen511]

@@613Builds Yeah. I'm in the same boat. I need a Posi. My 87 GTA was hit, and I replaced shell with 88 TBI bird. I never swapped the rear, due to time constraints. So, I have a 383TPI T-56 going into a drum rear, that I just did the brakes, and parking cables on. lol. I'm leaning LS swap though. I wasn't paying attention for like 10+ years, so I'm a newb on LS. Like, I thought the LS had different bellhousing than Gen II? I have a T-56 and bell from a 93 Camaro LT1.

[@613Builds]

Ryan MacEwen my previous car was an 87 hardtop , I put a 95 LT1 into that car. This is my first LS swap so it’s kinda new to me also. Same bell housing aside from one bolt. Although all the LS engines have a shorter crank (aside from certain 99-00 engines) so I used a hub spacer for the torq converter. The TPI fuel pumps make the same pressure as the LS but the TBI pump doesnt make enough pressure. Although it’s not uncommon for guys to put a carb on a gen3 engine. However I found the factory stock stuff is cheaper and works so I went the ultra budget route, and I wanted to prove some guys wrong who told me it would cost several thousand dollars to LS swap. I did mine for about $500 on the budget with new headers and new o2 sensors 🤷🏽‍♂️🙂

[@ryanmacewen511]

@@613Builds I saw that there was a missing hole in another LS video. I was under s strong impression that (gearing aside) the bellhousing spacing was different on T-56 bellhousings between 93-96, and LS 97-02 F-bodies. I swapped pumps as well. I went with a Hypertech inline pump on mine. Hasn't let me down yet, despite nay sayers. Fuel starvation was always an issue on my car in corners. I'm thinking of working in some sort of can baffle around pickup in tank. Awesome you were able to do it on a budget. I was one of very first dudes to do 6 spd swap in 3rd gen in 1999 (old news now). Got tranny for $1100 and a clutch disc for $30. lol. I'm looking into an LS swap and was wondering if I can keep my T-56 from the LT1 car. Flywheel mounting may be a bit different.

[@613Builds]

Ryan MacEwen wow that’s cool the t56 is a popular unit now. Yes I know it’s been done before, using the LT56 with and LS engine, I’m not sure what all is involved but it has indeed been done ✅. I think I saw it on sloppy mechanics public FB page or some place online. You probably know more about those than I would. My first firebird was a 5 speed. I’ve had 2 five speed cars but just t5. I’m currently running the classic 700R4 automatic , same as my last 87 LT1 build. The t56 isn’t exactly a budget oriented transmission so I haven’t had my hands on one of those yet but I think they are cool. Being a junkyard budget swap guy I’d probably go toward the NV3500 or 4500 transmissions if I wanted a strong manual gearbox because they are cheap and available in comparison to T56 units

[@613Builds]

awesome. i have access to and family at several bone yards too, i also grew up working at several yards having family into "the business" i wrecked them for 15 years now i look the other way, now i look at which ones can be saved and fixed and restored. but its nice to have access to cheap parts and 6L engines are a great find as they are very desireable due to the LQ9 being rated at almost 400 hp bone stock. i dont even know where to get a tuner locally and most people told me i couldn't beat the security without a tuner. but here we are and i got er running using junkyard stuff and no tuners, no help, no big wallet. just cheap junkyard stuff and hard work. i really enjoy building things myself or doing things myself whenever i can, it saves beer money and teaches you skills when you do it yourself lol.

Got an 03 Envoy XL for $800 a few years back from a trailer park. 220K on it and was not treated well. only straight panel on it was the roof, rest was "abused" with what appears to be a baseball bat. Trans had a stroke I believe, (takes >10 seconds to shift to 2nd). But the hidden gem is the (LS-style LQ4?) 5.3L All Aluminum V8. With your knowledge and a little push from Driveway Engineer, I might just get my money out of that stupid envoy. Will swap it into my 95 C1500 W/T after I pop the 4.3L Vortec with twin T-3 turbos and a FiTech Go-Efi w/power adder kit (~600HP) and MegaShift trans controller. Would just need to figure out how to re-flash the 5.3L Computer for boost.

[@613Builds]

LQ4 is. an iron block 6.0L. the trailblazer had an aluminum 5.3 or aluminum 6.0 (LS2) in the TBSS. bigger injectors might compensate for the air / fuel ratio but yeah 99-06 LS engines are great, and boosted applications should really be tuned anyway.

[@benjaminkeutmann2193]

nice video dude!! thanak you for sharing that knowledge! So let me get it right, if im getting a junkyard engine, can i run the engine with the original ecu, key and bcm (in the original car), disconect de bcm while the engine is runing, and i shoud be ready to take that engine and ecu for a swap? just that? thank you!

[@613Builds]

Yes, technically if you’re fast. but if you have the CPU disconnected for too long you might lose your memory and your bypass. Personally I got my swap ready to run, then I bypassed my CPU by using any old truck that runs and my CPU. Then I know my swap is ready and my CPU is ready and I can take the CPU directly immediately to the classic swap vehicle and plug it and i know it’s immediately ready. That way the CPU isn’t sitting around with power for days and losing its memory. This bypass glitch trick relies on a certain error code “lost communication with bcm, no security signal” . So if you fleet your error codes it won’t run. And if you lose your error codes it won’t run. Have the new swap vehicle ready to run if you can before you do this. That way you don’t have a dead CPU after more than one day.

So can you plug in the body module back in and computer and the van still run properly also can it be backwards like how you had to switch the color connectors would it work the oppsite

[@613Builds]

Yes you can re-assemble the van or truck no harm done ✅ also most of the connectors need co co-ordinate but my green computer came from an 03 express van which is also throttle cable not drive by wire so in my case they are compatible, but most of the green connectors are for fly by wire and they aren’t really compatible with a throttle cable harness and sensors I don’t believe

[@keliimanners6994]

That's good to kno. Can I use my donor vehicle that i will remove engine from plus all parts needed for my swap and do the same process? Would the pcm be disabled still when I pull and drop It in my project truck?

[@613Builds]

Yes you can use the donor , or another running vehicle with the same throttle type . Old Trucks can often be easy to find for cheap. I tried to do it as quickly as possible because it is possible for the PCM to lose memory after some time with no power possibly.

this is the 3rd generation which spanned from 1982-1992 a perfect decade of this body style. bumpers and tail-lamps were changed in 1985 and 1991. this car is a 1983 model. but the GTA hood i mounted wasn't available until 1985, which means that this bumper was never available with this hood from factory, but i think the ram air intake grilles match the bumper grilles nicely.

you can install the 5.3 CPU then do the the key relearn. it will take 30 mins then youre golden. the 4.8 CPU should work but the 5.3 CPU will work after doing a key relearn like i did. it matches the CPU to the BCM :)

for plug wires, use wires from the 8.1L ls engine, the have an angled wire from the spark plug.

[@613Builds]

good idea! thanks for the tips and the input

[@tirbomax]

I had to use the 8.1L wires on a turboed setup that the stock wires would hit the header worse than yours.

[@keepthelikesat710]

I have a running 5.3 I'm planning to put into a 99 tahoe Obs, I'm not switching pcm for another one. Would I still need to do the same thing with the original pcm to delete the vats. 10 min 5sec off x3 then unplug the bcm, and the vats would be deleted and the motor and pcm can just get thrown in the tahoe, and wen ready it'll fire up without security

[@613Builds]

If it’s already running you just need to unplug the bcm while it’s running . Then turn it off and make sure it still runs with no bcm. Once you have it running with no bcm it’s ready

You can typically start the vehicles normally with the key and no harm done to the running vehicle. It’s easy to put things back they way they were.

yeah im following you also thanks. yeah same process but you dont need to swap CPUs like i did, and you don't need to wait 30 mins. just make sure it will run and start again without the BCM and then it will run in a classic swap or stand-alone, without security interuption

this worls with the 99-06 style CPU . ive never tried it with the 07-13 models but the engine is basically the same. i dont know if the 07-13 even have a BCM so im going to assume this would not work on the 2014+ models and might not work on the 2007-13 models. i have labeled this as 99-06 compatibility. 2015 is too new and valuable and expensive, too new no to fix, too valuable not wreck, and too expensive for an old budget build LS swap. this is a budget build under 1k and im afraid i canèt tell ya much about the newer ones because i dont know. im pretty sure if you use the newer block with the older harness and older intake and sensors you could do it, as long as the crank sensors are the same reluctance. a friend recently bought a new chevy truck and it still has the old 5.3 in it so im guessing they are still using the same old block but i couldnt say for sure

just unplug it while its running like i do in this video. you might have to do the middle plugs first (left to right) then the outter ones. thats how i did it , if i remember correctly. the order might not even matter. make sure the truck will start again WITHOUT the BCM and then its good to go

One other question my motor is a from a 06 silverado do u know from what year to what year of a donar I should look for

If you already have an engine what do you require a donor for? If you want to unlock your ECM/PCM/CPU you’ll need a good running truck , rather than a donor. Yours Should be 03-06 with the electronic throttle and 24x crank sensor , if your cam sensor is at the rear like mine. note: Some of the GEN4 engines started in 06-07 but they have the cam sensor on the front timing cover so they are easy to sort out , and they have a different crank sensor with different reluctance and totally different computer . The 99-02 will have a throttle cable, but the 03-06 will have an electronic throttle body. 07+ will have the cam sensor at the front , 99-06 will have the cam sensor at the back.

I think I’m using the 95 firebird 4l60 shaft but all the 3rd and 4th Gen overdrive shafts are interchangeable aside from old early 3speeds which had a longer shaft. I’m pretty sure 700r4, T5, 4L60e, t56 all use the same length shafts from 3rd and 4th Gen camaro and firebird from around 1983-2002 . I’m using around 1” setback on my LS mounts which is pretty much stock bellhousing location for older small blocks .
