This may be a stupid question, but can you change the tunes on a DSP 5 switch with a V2?
100% yes if you already tune with that V2 as have it VIN lock to the truck you can re-tune as many times as you. kinda whole reason V2 so good. autocal can also does the same but you must have the original tuner do it.

Let me update on my problems with out having my own V2, I have paid 500 bucks for tuning on my truck and a dsp5 switch, I need my tuning changed to run a bigger turbo and supposed to have life time changes on my tunes. Well my tuner has falling off the face of world and can't get a hold of him. So know I have to pay someone else to tune it. I now will be into tunes more then what it would have cost me to buy a v2. So now I am buying my own v2.

Having your own V2 takes all the drama/flaming hoops out of making ECM changes.

No, your factory intake will work good.

Can you access systems such as Airbag or ABS with V2, or is it only ECM and TCM?

exactly right except one V2 can only use up to 220 VINs. 1 vin per truck 220 trucks. idk who ever tune that many trucks unless you were tuner of some sort and very good at it.
Good point. I was being a bit facetious when I said 1,000 but incorrect info is still incorrect info. To fulfill all 220 VIN licenses it would cost you a cool $220,000.

Just to clarify, I'm getting efilive V2 for my 08 LMM, and if I want to tune my wife's 2012 suburban all I need to do is buy a new license? If that's right, how much are the license?

A new V2 comes with 2 ECM and 2 TCM licenses so all you'd need are the tunes for your wifes Suburban and your Dmax.

I just want to say thanks for this post, I had ordered a autocal on friday but after reading this post I was able to change my order to a V2 before it shipped. I have the 03 with a 6.0 gas so it makes sence to be able to tune it as well:gearjamin

Can a V2 with zero licenses left be cleared and start over?

A V2 with no licenses is fine, just buy another license (or as many as you need) from EFI and you're good to go.......V2 price should reflect the lack of licenses though.

I squirreled $650.00 for my used V2 (creative money laundering), had 1 ECM "license" and two TCM "license" left. Now I have to buy another license for my backup ECM which includes one ECM and TCM "license". Most used V2's for sale have only 1 ECM license used.

That part most confused with a license purchased from EFI is it includes the ability to tune 1 ECM and 1 TCM...:rolleyes: My tuner is a private individual and the tune is not locked and can have it changed anytime I want, I did dial in the speedometer and now reads dead on (+1% or -1% OK 2%) with the fuel mileage on the DIC when I hand calculate the mileage.

I do not have the experience to change other parameters but my tuner will if I ask. Just be carful of tunes/tuners that lock your ECM, locking the tune I can live with just not the ECM. To date I'm still reluctant to change/tune my transmission, works great the way it is with just the ECM tune around 90hp and have it run a long life...:thumb

This is what might happen if I change any other parameters..

Just compare it to having sex with your cousin.......it can get the job done.....but the longterm effects can really F%$ something up
