- In this video I use HPtuners to deactivate the GM Displacement On Demand also known as Active Fuel Management.
When you go to read the vehicle, only read the engine. This will allow the use of only 2 credits by doing this.
This needs to be done after the DOD cheat repair I have shown many of you it also needs to be done when removing the DOD.
If you only need to do this on one vehicle I recommend finding a local speed shop that can do this for you or using LT1swap.com . Don't forget to write the tune once the DOD is disabled.
I have the cheapest option below so check this link out • Pulling Your GM Truck ...

HP Tuners with 3 credits 2 is the most you will need. Seems amazon at time of this link didn't have much for options so see if you can find 2 credit version to save money.

Fixed my tahoe just using the hp tuner, no more lifter problem, thanks!
Picked up the tool from your shop yesterday. Popped it free today with minimal effort. I was fortunate to have this issue about a block from my house so that's all that the truck was driven before fixing. Actually this happened as I was getting off the highway which explains the situation perfectly.
Dougie Fresh are you driving it?
@@grad0n Absolutely. Gave a good couple stomps since it had unspent fuel still in the exhaust. Replaced valve cover gaskets and grommets, intake gaskets and injector O-rings since I already had all that stuff pulled out of the engine bay. It runs great and just took it on a camping trip.
Dougie Fresh you didn’t change out the lifter?
@@grad0n Nope. Just knocked it free. No need to pull the heads if I dont have to.
Dougie Fresh that’s what I did with my Dad’s 2012 Escalade that failed in his driveway. What oil pressure are you seeing at hot idle?
Awesome.im doing 06 impala ss and i was debating on getting custom tune for 1000$ .now im doing hp tuner route
I like it! Scary when you see the word BRICK in red. Thanks for the info.
Must feel so satisfying clicking that button every time. AFM be gone! I did not buy a V8 to drive a V4
absolutely, i don't understand why GM put AFM in those cars.
even C7 corvette which is a sport car
@@irvineoc4804 as for the Corvette who the hell knows. As for pickups, huge marketing sell for fuel economy. When this "technology?" came out, gas was very expensive.
I am here today because i just bought one and i thought something was wrong with my car.. pipes will roar when i punch the gas.. but if i start slow, it will growl and sound as if its straining... am i in the right place?? Im annoyed
@@WSYSlowMoe716 is your vehicle throwing a code?
I believe it is because of Obama. When he imposed more strict CAFE regulations, GM's pushrod V8s were not up to snuff on the new emissions regulations and they had to come up with a way to quickly get their muscle cars to pass. Ford was prepared for this with their modern DOHC engines and GM sadly was not.
Last month I gained intimate knowledge of this afm nightmare on my Dad’s 2012 Escalade with the 6.2L with ~130Kmi. He started it one day and the mystery noise of an afm collapsed intake lifter #6 reared it’s heel. We were able to free it up by tapping it through the oil feed in the lifter valley. I had fun sourcing the 5.3 lifter valley afm gasket(nobody lists the gasket for the 6.2l escalade 😠) and replacing the old one. Dad wants to keep afm, but i’d tune it out like you show here.
I am not sure why anyone would want to keep the system active but if you do, you must address all oil pressure issues. Depending on many factors this might involve a higher than factory volume pump.
CrazedPerformanceRepair I replaced the oil pressure sensor and cleaned out the screen there and the 4 screens on the valley plate, so hopefully it’s in better shape than before. I would delete it if it was mine and uncork that 6.2 in the process.
@@grad0n was the screen under the sensor plugged tight or just a little dirty?
CrazedPerformanceRepair just a little dirty.
@@grad0n just realized I never mentioned if the lifter has failed already your only choice is to release and shut the system off or replace the lifter. Then of course the rest of the conversation still applies. So then the screen is not the source of your issue. You might have a slightly worn out engine. Oil pressure is always why these fail. Loose VLOM bolts causing bad gasket, oil sump o-ring, slightly worn bearings, leaky lifters, the screen is plugged, something made the system activate with less then 27psi at the lifter that failed.
About to pull the trigger on a 2015 Silverado on Monday possibly from a local truck dealership but Truck had stabilitrac & cel light on after about 10 mins into test drive (bummer) but your vids are so helpful and make me more at ease about buying a Chevy 5.3 now. I love the truck so id do the obd2 plug in delete first propably just for peace of mind, but considering doing the full delete if the plug in tuner doesn't solve the issue. Your vids rock! \!Subbed!/
Excellent vid thank you
I have dod disabled but the tuning for dod cylinders is for like 40psi less=less fuel. I have a stock non dod cam but only have dod turned off. Does this put the same fuel to all 8 cylinders? Thanks.
Do the afm disablers that plug in the diagnostic port actually work for disabling the afm/dod? And if so, will it work for the vlom mod instead of a full tune to disable?
I need some help, I am new to HP tuners and my understanding is limited right now. I followed what you where doing and I paid for my credits and thought things would go threw perfectly. Now the truck will not stay running. It will start up and shut off right away. Can you help me?
Will the SUV still pass admissions if I delete it off the software AFM?
I installed an afm delete kit on my 2007 suburban can I just disable with hp tuners even though the connector to the VLOM is not connected
Just wondering, could a Yukon XL with a 6.0 have an air filter housing that says it is 5.3 ?
Pretty sure it is 6.0 because that is what the registration says.
Hi
I took your advice and sent my ecm to lt1 swap to turn of afm/dod. I reinstalled ecm, charged battery, started it and no cel👍🏼
I then drove my 2012 Avalanche LTZ into the sierras, switched through the 2hi, Auto, 4hi, 4lo to see how it performed in the snow.
No problems there. Drove it back home, round trip of roughly 70 miles or so. After stopping for gas the truck went into 4lo without moving the rotary switch. Would not come out, service 4wd light came on and it’s all wonky now. Switch position shows random gears whenever I restart. And code C3098-5A shows up on my xtool A30M scan tool. Would the ecm mod have anything to do with this situation. Or is it sheer coincidence?
Thanks, Mike
can to shut the secrity system off with the hptuner . i did ls swap 2001 tahoe and the S S has it shutdown ?
I just got a 2009 silverado 2500hd crew cab 4x4 6.0l "work truck". I think it's had a DOD/AFM tune done to it already. I don't see have both aft/rear O2 sensors installed and I get no errors with my obd2 reader and my android phone using torque pro app. I read somewhere I can put my gear shifter in "M" and manually press buttons to select how many gears to use and at same time this "M" mode disables dod/after but I don't know how to changes this as my model of truck is the work truck and don't have the volume up and down buttons. When I have the gear selector in "D" I always see a "1" on the right side of the "M". It don't change. Ok now the real question. Does the hp tuner perm program the ecm or can I reset ecm so it loads all factory settings? The guy never said he had a tune done to it so there is no original backup file before any alterations if there were alterations. Nice video btw
2008 impala 3.9 DOD stopped working when the oil pressure senser stopped working no leaks runs great
Can you tell me the number of your hp tuner and where did you Buy it from thanks
Do you need credits just to disable afm ?
So just did a dod delete kit on my 2010 Camaro ss won’t start tho is this what I need to do to get it running?
It should still have ran but this does need to be done as well or it will go into limp mode without a VLOM plugged in. I would be concerned about cam timing or having forgotten something when putting it together.
Can Any one tell Me, please
How much can coast me, to pay someone to due that Tune on my 2008 Tahoe.?
Please,
Thank U in Advance to All
I have a misfire on my #6 cylinder. This is after they replaced the camshaft on my 5.3L. it only gets 10.6 mpg. It has low oil pressure, also. What is it?
Sounds like some sort of clearances have been thrown off. It’s likely that you got your camshaft swapped and either didn’t delete AFM, or the cam you got is too large and your VVT isn’t capable of supporting the bigger cam lobes. Make sure both AFM/DOD was deleted, as well as VVT.
Does disabled DoD prevent lifters from collapsing/failing? Or will dod lifters still eventually fail at some point?
It should unless the VLOM gets plugged up or a lifter spins in the bore.
Kinda off topic but will the HP tune software turn off the EVAP test so my check engine light will stay off?
Why don't you fix the problem instead? Let me guess you have a solenoid control circuit or large leak code? I will be releasing a video very soon on this topic.
I have a truck that appears to have a grounding issue in the ECM that's causing a solenoid to stick open anytime the key is on. After doing the disable can I unplug the vlom without throwing any codes? And have you done any videos on what you have to do to the vlom regarding oil flow to do a disable. Thanks for the video!
Yes you can unplugged it without codes once disabled but why? Here is the VLOM mod that I do currently czcams.com/video/pP7I5tbXsfw/video.html
I've got a contact of a guy who does custom tuning for 450 bucks . A hypertech programmer is the same price . Which one is better in your opinion . Both can turn off DOD and other functions
What else does the tuner do besides delete dod
I have a question if you don't mind. i purchased a 2018 chevy silverodo, it was a fleet truck. well the truck runs perfect. But when reach 70 mph the truck won't go any faster , evven if mash the gas pedal to the floor. it's a v8 with 140 mph on the dash. what did they do to govern it down & how can i remedy the problem.
Most likely something was done in the tune to keep the drivers from speeding to badly. You will need someone to go into the tune and return it to stock or remove the limiter.
I have bought used trucks same thing, companies order new trucks with the programmed governor right in the ecm. Its actually a RPO code in glove box I forget which it is.. But yes anyone with hptuners can use $100 worth of credits unlock the ecm and change the setting in 15 min. I did it myself after buying hptuners and have used it at l3east 6 other times on new vehicles making changes, disabling DOD VATS etc
If the battery is disconnected then reconnected, will it set everything back to factory settings?
No not at all.
Two things: (1) Does anything need to be hard-wired in or remain plugged into the vehicle for this to work? (2) Do I have to do an actual delete kit first (cam, lifters, etc)? I'm trying to avoid the $3000 to replace the lifters if possible (I have what I believe is a stuck lifter and will try your method for releasing it using the pushrod tool first, but would rather try to avoid rebuilding the engine if possible if this tuner and your lifter release trick works and this keeps the vehicle out of DOD mode/prevents the lifters from collapsing down).
Heelix Ranier What did you end up doing?
What did you end up doing. I have the same problem
@@joshuasanchez1120after freeing up the lifter if you can the odb tuner works well. The bad thing about the tuner is at any time it fails or gets unplugged the lifter will immediately fail and it sucks having to tear the motor apart again but it absolutey works. Been 6 months with no problems.
great video. so it works for c7 corvette too? (DOD disable?)
i've heard of that AFM causes T/C problem on c7 vette
and i'm considering getting c7 stingray or GS. so..
Anything equipped with this system I recommend turning it off.
@@CrazedPerformanceRepair thank you! i think i should get the one latest model with very low mileage and turn that off
Question for you. 08 Tahoe, 185k miles, no current problems. If it were yours, besides deleting the DOD in HP tuners and checking the vlom bolts for looseness, what would you do to try to get this thing to 250k Miles?
That is all you need, just keep up on the maintenance. I have seen many of these well over 300K miles.
@@CrazedPerformanceRepair Thanks for the response Sir! One more questions, do you find the updated 2011 and newer driver side valve cover to be worth the $100 price to reduce oil consumption?
@@Toys4Life Yes
@@CrazedPerformanceRepair Thanks, I appreciate your input!!
Do you need to mechanically disable the DOD also. Mine is still working fine but I will be doing a delete and cam in the future. Can I simply turn it off in the ecu to stop the exhaust note when it's on 4cyl
Yes, you can just shut it off and it will stay in v8.
The tuner.you have do they still sell that one or did they make newer ones
They have a newer version
Ive programed new ecu and also new tcm with my autel j2534 & laptop on ac delco site with subscription. Can i also do a afm delete through ac delco or i need a tuner? Thanks
Probably need a tuner. Unless you can flash it with a non-AFM compatible OS from another vehicle. You would have to do your research to figure out what has the exact same features minus the AFM. Might be able to find something from a 2500 if it's a truck you are working on.
@CrazedPerformanceRepair thank for the reply 07 5.3 yukon lifter issue pulling the engine & thinking about doint a afm delete same time or i have a 07 escalade with the 6.2 non afm i can do a swap & just carry over the ecm. I know on ac delco site i can purchase other programs but im a lil rusty on this computer stuff lol
What are your thoughts on the Range AFM disabler.
If the vehicle hasn't had a lifter problem yet it is a good way to prevent a problem.
My GMC sierra Denali 6.2L took 3 credits to unlock the govenor... the site claimed 2 ... just be aware and expect the unexpected 😅 extra $50 sucks but hay I have a fully unlocked system now. Buy once cry once.
🥃chees🍻
Hi there,
I saw that you read all three modules. If am only disabling the DOD can I just read ECM, same with writing. Or you think I might have issue or the tune won't work right. Thanks in advance
Yes you can just read the ecm and save buying the 3rd credit
@@CrazedPerformanceRepair thanks again for replying 👍🏽
@@CrazedPerformanceRepair will be tuning soon 😌
You can disable AFM with a DiabloSport Sprint Chip as well...cost me $200 CAD. Plug it in and drive
Using LT1swap.com is only $50 and shipping to him.
What I am having trouble understanding is if this DOD delete gets rid of the pressurized oil that pushes in those pins, allowing the lifters to collapse, the loud lifter ticking noise before the repair wasn't due to a lack of oil getting to the lifters?
The lifters get disabled by adding oil pressure but if there is not enough pressure for example a plugged screen the lifters will damage themselves.
@@CrazedPerformanceRepair Right, but I wonder why the collapsed lifter results in a loud lifter ticking/clacking sound. Anyway, I tried your method of releasing the lifter using a sanded push rod, and it worked great. Thanks again for your efforts.
@@WILSON.1 that is from the pushrod smacking the rocker.
@@CrazedPerformanceRepair Ah, okay, that makes sense to me now. Thanks man!
I'm going through this, the dealer quoted me for $10,800 for a Jasper engine Diablo tuner with a 4 year warranty but obviously I'm not doing that for an 08 truck that I owe 19k on I'm taking it to a gm tech that works for the county now I'm just curious what you charged for a delete kit and tune out if the afm. He is going to take it apart and see what's going on and tell me what I need if I need new cam and all I need to replace. Thanks been hooked on your videos since my truck did this. Your really good and explaining everything I've learned allot from watching your videos
So a dod kit isn't needed, if I'm installing a cam on my 2008 gmc?
Yes you will need a kit to remove DOD if you currently have DOD. The electronic and mechanical side of the system are separate but work together. This video is only turning of the electronic side of the system.
Basically, the components are still in the engine, doing this HPtuner method just turns them off in the computer. If you want absolutely no chance of the DOD/AFM system harming your engine then you should remove the physical components and replace them with non-DOD parts. This is relatively easy to do, but takes knowledge, time, tools, and patience to do correctly. Most DOD failures happen during the transition from v8 to v4 (or vise versa), so turning them off greatly reduces the chance of failures happening.
Hey I have a question, so I did a DOD delete kit install but I haven’t done the tune yet. I turned it on and it’s slightly misfiring as it should but my oil pressure is not reading at all ( I put a brand new oil pressure sensor), is that what’s suppose to happen until I get it tuned?
No matter what you should have oil pressure.
CrazedPerformanceRepair where should I start investigating ?
If you did a full delete this means you replaced the valley cover, correct?
CrazedPerformanceRepair yes with a smooth non dod one from Texas speed
Btw ... when I removed the sensor from the old dod valley cover, I removed it with a power gun. Could that have broken something inside the sensor?
on the 2011 6.0 hybrid, is this doabul.
I have not got one in yet but I have heard that can not be done.
Can I disable dod/afm before I get any lifter problem? Can I just disable it and I’m done? Or what else would I need to do? It’s a 2014 caprice l77
Absolutely a good idea to turn it off early the only other thing I suggest you do is check the VLOM bolts and make sure they are tight.
CrazedPerformanceRepair so no need to do the VLOM mod?
What I could say is I have a cylinder 8 misfire it does sound like a lifter noise but I believe cylinder eight isn’t that style? Haven’t looked at it yet but will soon and while I’m there I’ll delete that system
@@youngcurls1 Cylinder 8 is not a DOD cylinder. As far as the mod goes, it is optional if you haven't had a DOD failure yet. If you pull the VLOM off for any other reason than at that time it's a may as well do the mod since you are right there kinda of thing. The VLOM mod is kind of like an insurance policy.
CrazedPerformanceRepair ok cool man I really appreciate your help and fast reply
Some shops say you have to do a mechanical components change also.
Truth?
Is it okay to just disable the DOD on HP Tuners even if I dont install a DOD delete kit such as replacing cams, springs, retainers etc?
Yes it's fine to turn off
@@ian_jc isn't that the same question as SrichampooTV?
Can i tune it out in california???
@@CrazedPerformanceRepair can i tune it out and be fine in california???
@@NORCALPYRO_ yes, it will act as if it's a non AFM engine. Just don't tell them you did it and you should be fine.
You don’t have to spend 3 credits on that. Just when you begin to download select just pcm and trans. Then will only cost 2 credits.
That's what I thought too but it wouldn't continue without it unless I did something wrong?
No just select read ECM only and read
@@jcw2002 that's what I am doing now still waiting for a newer one to come in the shop that is new enough I know for sure it was the 3 credits. So far it's been 2007-2010 since I started doing this process about 2months ago
@@CrazedPerformanceRepair i just did it to mine after i the cold startup lifter tick got much worse one day.
I already had it unlocked via hp tuners to firm up the shifting in the 6 speed...
Googled the issue and instant hit for the dod issue.
From my first transmission edit, hp tuners says my vehicle only needs 2 credits.
I believe that's the trick here.
From my reading, the third credit is an extra thing that gives you more options should you wish to go boosted.
Just exclude the third module when doing the read.
If the dod option is missing, then you know it's in the extra module.
so that l increase usage of gas
This was a great video, and I have a question for you. I have a 2012 Silverado, 5.3 4x4 and I just put in new LED turn signals bulbs and they hyper flash. Their is no relay for it and is controlled by the truck computer. Do you know how to and where you adjust this with HP tuners. Thanks again for the good videos.
It's a resistance thing. You need to go to Amazon and buy a 50w 6ohm resistor for each bulb. You wire one side to the blinker wire and the other to the ground.
Would there be any problems if I disabled dod in the ECM but left the OEM hardware in the engine? As in I've got a low tick on startup that stops after a minute or so but no other problems... Yet also can that programmer turn on remote start. I put the remote start fobs in and can see in the ECM when the start button is pressed but I need to get factory remote start turned on.
As long as the VLOM doesn't cause any issues it's fine to disable DOD in the tune. In fact I recommend it. As for the remote start part of things I would have to do some digging (start with google) I'm not sure I never tried it. Perhaps contact hptuners and ask them. I would think the body module would need a flash more than anything and I don't believe hptuners does much in that department.
can i just turn off them afm/dod with no wrenching .....just use the program to turn it off.
i have no lifter noise but misfire on cylinder 1 and 7
2002 5.3
Yes but I suggest you watch czcams.com/video/pP7I5tbXsfw/video.html for your misfire to look into what lifter issue you may have. Cylinder 1&7 are AFM/DOD so you may still have a failure. Also if all you want to do is turn off the system I suggest lt1swap.com he is much cheaper at only $50
Hey man hopefully you can guide me to the right path I have a L77 with cylinder eight misfire no code yet I was able to look at the misfiring data and see it was cylinder eight, engine running rough on lower RPM swapped coils new spark plugs new wires even swap injector compression is good. is it possible that a lifter could be weak causing it to misfire and still have good compression on the gauge while cranking? I could hear valve noise as well
Cylinder 8 is not a DOD cylinder but you might have a wiped out cam lobe. Pull the valve cover and compare cylinder 8 rocker movement to the other cylinders.
No, you would have low compression with a weak lifter or worn out lobe. Your problem is probably electrical, wiring, injector or pcm
Can i disable with hp tuners on a california vehicle and still pass smog???
Yes, smog doesn't check the tune file. It only checks for codes and checked exhaust with a sniffer.
@@CrazedPerformanceRepair ok just wondering cause supposedly california will start checking for tuned ecm thats why i asked
@@NORCALPYRO_ well if they do that one we'll have to resort to vin tag and badge swapping with 2500 hd or something then righting the tune to match that vin. Of course this would make things complicated and false.
Reality is one should just move out of that retched heck hole of a state. I hope not but won't put it past them to implement it. After all they are banning fossil fuel vehicles soon. You know, so that electric cars can add strain to the already overstressed grid because that makes total sense.... 🙄

If it's equipped with AFM, yes.

@@CrazedPerformanceRepair link is no longer working. Is it a tuner device or only a software and license/credit?
is hp tuners a free software?
Software is free but the unit cost money and so do the credits to unlock each vehicle
Does that HPtuners software require yearly updating or a yearly fee or you just purchase once?
I did this a couple weeks ago (after using your patented CPR lifter punch rod to open the collapsed lifter, thank you very much). HP Tuner credits are $50 each and you look up make&model to see how many credits are needed to unlock and reprogram a single VIN. For the 2013 Yukon this was 2 credits. It then took one additional credit for "the file", not sure what this was about but after boofing up another $50 I could then write to the truck. It was made clear that I now have UNLIMITED access to reprogram this truck as many times and for as long as I want. For another 10 credits I would be able to upgrade and write to any 2013 Suburban or Yukon XL.
