Questions and Answers

Can use this tuner after the stuff have been removed?

This is the device the you'll need to flash the delete tune, and then remove the physical components after the tune has successfully been flashed.
Can I use the blank efi live to pull my file off the truck and tune it myself or do I have to buy tunes from other tuners

You will need to buy custom tunes if you plan on tuning your truck, the file you pull from the truck with the Autocal would be a stock read, and you won't be able to do anything with it.
I have 2014 Jeep GC diesel. Can I tune and disable the DEF with this?

You will want to look at something like -> THIS.
Do you need a computer to download the tunes and then upload them into this tuner? If so does it come with the required cables to connect to laptop?

This will come with the required hardware to plug into a Windows based laptop for tuning.
Hi, I'm looking to buy one, I have 2 trucks, and 2013 ram and a 2022 ram. Am I able to tune both of them with one device? Granted I buy an additional license? Would I need additional wire harnesses?

You would just need a VIN license per truck and you'd be good to go! You'll need a bypass cable for the 2022 but on the 2013 you'll be able to tune just with the Autocal device itself.
can I get 2018 ecodiesel tunes on this

No. You will need this HERE.
If I already have tubes loaded in and my dps5 switch is broken, can I still navigate my old tunes with a new auto cal

It depends on if you have 1 SOTF file, or all tune levels as single files. If it's 1 SOTF file you will be stuck on level 1 unless you install a new DSP5. If you have 5 single tune files, you can manually reflash the tunes to your desired power level.
Can I tune a 1999 ram 3500 automatic 24v Cummins?

Unfortunately, no. You will need to use an MM3 device paired with CCS tune files.
Can this be used for a 2024 Ram 3500

You can use the Autocal on a 2024 but you'll need to have a swapped 2019-2021 ECM installed in your truck before you can tune.
Will this delete all codes for my truck it is limp mode now

This device by itself will not, you will to pair it with custom delete tunes.
So how much is the tune and license for a 2007 Ram 3500 and a 2020 Ram 3500

If you've got the Autocal you'll just need to purchase 2 VIN Licenses, and your tunes for each Ram HERE. For the 2020 Ram you'll need an extra bypass cable.
Can I check injector balance rates with this tuner?

Yes.
Can you tune a 2020 powerstroke or do you have to send in the ecu??

For tuning a 2020 Powerstroke, you must send in the ECU to be unlocked, as direct tuning isn't possible due to the factory encryption.
Can you put your truck back to stock with this tuner?

Yes, it allows you to return your truck to stock if you have a saved stock file.
Does this device have a preloaded tunes to delete emissions?

This is a blank device, you would require custom tuning along with it.
hi, what happens when you buy a used EFI live autocal v3 and come to find out it was used for a cummins and you wanted to tune a Duramax can it be done by buying a vin and tune from the same tuner or whats the steps if possible to have that autocal v3 be used with a different vehicle and is it locked to that pacific tuner and if so can a person just get tunes from that tuner to match your vehicle and is there a way to find out who tuned that autocal v3 ? sorry im new to this autocal world lol... thanks and hopefully you can help me out cheers!

You can use the Autocal you have, you will just have to get it unlocked from the previous tuner or go onto the EFI Live website and pay the unlock fee of $50. They will provide you with an unlink code. Follow their instructions to unlink it from previous tuner, then you can purchase a new VIN license and tune file package through our website and you can tune the truck. There is no way to tell who previously tuned the truck.
will this do emission off tuning for a 2020 powerstroke

You'll want one of these options HERE.
If i'm just looking to delete my dpf system will this work or do i=I need a preloaded tune for that? Thank you.

The EFI Live Blank AC3 AutoCal requires preloaded delete-enabled tunes to perform a DPF delete. The EFI on its own will not work to delete your DPF.
Will it work on my 2022 high country 3500

Yes!
Does this work on a 1998 k2500 6.5 detroit diesel??

No.
will this delete the regen function and EGR on my 2008 duramax when i remove them?

You'll need to get a delete tune as well that this tuner can load onto your truck.
Can this be used to tune a 2020 6.7 power stroke?

Unfortunately not, the 2020 requires the ECU to be sent in and bench flashed.
I bought an autocal v3 for my 2019 Cummins can I use it on my 09 duramax if I buy a new vin license?

Yes.
Do they have emissions-off tunes for 2021 Powerstroke?

No.
So basically I can buy tunes for multiple trucks and use the same tuner?

That is correct! As long as you purchase a VIN license and tunes each time, you can tune up to 600 separate VIN
Can this tuner save the stock tune from the truck. I want to egr delete and dpf delete my truck is it the tunes or the tuner that will keep the engine light off thanks

Yes it can save your stock tune. The custom tunes will also ensure the engine light stays off after EGR and DPF deletion.
Do I need an unlock cable for my 2016 ram 2500 like other tuners require?

This will come with the OBD cables and USB cables you need.
Do you have to buy every tune? Also since it's blank you buy the first tune?

These are blank, however we do offer V3's with preloaded tunes for 01-16 Duramax and 06-2020 Cummins.
