Ok, If I buy a second ECM programmed with my VIN number (and all the same data as my stock ECM) for my truck, will I still be able to use the current License on my V2 or will it require to get another license.

(also I know the V2 comes wih 2 licenses, but I used the second on another truck.)

Thanks.

Yes you will need another license, the VIN license actually refers to internal PCM/ECM/TCM serial codes that EFILive locks a license to. So once you license it, you can swap it to unlimited cars or flash whatever VIN you want to it.

Remember your unit comes with 2 open licenses, so if you have only programmed your truck then you won't have to buy another.

A license attaches to one PCM/ECM and one TCM... regardless of VIN.

Why are you getting another ECM, is it a spare...?

Thanks Ross, I knew that. Also you get my email about the EGR on LMM?


I am getting another ECM that I will tune Different. So I can swap it out without re flashing my Race ECM. I can pull my ECM and replace it in less than 5 minutes and dont wanna always carry the laptop and re flash.....For right now atleast......:hihi:

My other license is used up on my buddies truck, because his tuner died on him at the track, so I just converted him over to something a little better....

No I mean CAN, if you take your ECM and throw it into another LMM and reprogram that trucks VIN you wont have to burn a license. The license it locked to that ECM, nothing else and nothing more.

ah, I got you, I was thinking you were saying I'd program my NEW ecm with my vin, then flash a tune into it with another vin and never use a license.

I got it now guys, Thanks.
