Thanks man! this totally worked for my ls swap. It was popping and banging, lots of weird stuff before I disabled VVT and AFM

Great vid , would love to learn more from you I real wish you give basics LS cam tuning after swap ?would be so helpful thanks

Awesome vid. All info you have given has been awesome. 👍😎👍😎👍😎

2016 Yukon L83 with cam with a 4 degree limiter, ported heads and a 3000 stall. No power from a dig but I thought it was due to the 3.08 gears. Do I follow these steps for my setup as I have a limiter or do I follow a different approach? Turning off the VVT with a limiter bad, good or indifferent? Trying to get it to have better take off as it feels like I'm pulling a trailer out of the hole. Loving your videos!

Love your videos, thank you for sharing your knowledge and experience, quick question, I have 12 Sierra 1500 with a 5.3, I did a DoD delete (sadly after a DoD lifter decided to spin on me) I didn't do the VVT delete when I did the DoD delete, is it possible (and safe) to disable VVT without doing a full deleting, or should I keep it somewhat active, eventually I will do a full delete and up my cam to a stage 3+ for that power and sound every V8 should have, but until then I'm trying to safley squeeze the most out of my 5.3, pretty much everything is stock aside from the lifters and cam,

I currently have a gen 4 6.0 from a 2500 truck. I'm also doing a Swap to a squarebody and going carb. Would changing everything, VVT delete, new cam, new cam sensor be better off? Your videos helps but I'm going carb conversion. Thanks great video.

What about VCP spark tables after you smooth out the VVT high baro table?

I'm putting an LS3 in place of an L92 in my 08 Escalade. The LS3 has no VVT or AFM. This swap will eliminate the VVT solenoid and VVT front cover. I'm assuming I should just zero out the intake cam VVT numbers . Will the PCM set DTCs for the missing solenoid? Can I turn off those codes? Great Video BTW!!

I have an 2007 yukon denali 6.2 with vvt its not an afm motor I tow my car to the track with it do u think it would be beneficial to disable vvt on it for more towing power and a little more power up top?

I have a 2010 silverado with a blown 6.2 in it. I can't afford to buy another 6.2 but I can get a 5.3 cheap. My question is can I put an older 5.3 that doesn't have the vvt in it and have it tuned out on my truck???

Hey there I’m working though your videos and am so bummed it’s taken me this long to find your channel. Something I’ve wondered before, when we are trying to disable any specific function there are often multiple variables than can enable or disable. Like at 7:30 of your video you go though and disable each variable. Would it not work the same to just disable one? Set enable vs oil temp to 400 and then nothing else matters because it’ll never hit that right? I’ve often wondered this, would appreciate any input.

VVT : more overlap -> engine breathe better at high speed but poor performance at low speed (better for higher rpm), less valve overlap: more torque at low speed but low high speed performance as the engine can't scavenge the exhaust gasses with high rpm. So why disable valve timing, when you can stress this value more having a more aggressive toque at low speed as an engine that breath at full rpm? Don't bother with math with a fixed valve timing makes thing easier with less headache, but not as best as using advance technology to get both of the benefits. VVT was probably invented for the emissions purpose, that doesn't mean that if you know how to play with those values, you can have high torque AND high speed breathing engine all together, a surely better choice that giving up one of the two, disabling the VVT

Aren't you opposite on what the VVT system is doing? You stated that the VVT is a system that allows you to advance the camshaft up to a certain amount of degrees...? Then you stated that it's primary purpose was is for emissions...? It's my understanding that the VVT is designed to broaden the Torque curve of the motor by retarding the cam for upper rpm power. The VVT cams have additional advance ground into them for low end power and the phaser retards the cam for upper rpm power so the end result is a wide flat torque curve... right?

@GoatRopeGarage

4 жыл бұрын

It is parked at full advance, I mistakenly said the wrong thing there. And while it can be retarded to create additional cylinder pressure for more down low power, it's more for emissions, you can see that based on the tables and where it does the most changes is in the cruising areas on most platforms. It also crates a layer of complication when tuning that generally is easier is you simplify the adjustments.

Take it to the track, do back to back runs, one with VVT disabled and see what it does. You're comparing two cars, I tested it on the same vehicle, only thing different was the VVT was on versus off and it ran faster off

When vvt is tuned properly and you actually know how to tune vvt it's beneficial for most people to utilize it unless you've done a DOD delete

AFM/DOD has nothing to do with VVT. I deleted afm and kept VVT and also am turbocharged. Using a 6.2l VVT cam in a 5.3l LC9 engine.

It makes no sense removing the cam adjustment. This guy is talking rubbish. If you don't understand how to make the adjustment get a tuner.
