Question about Smarty Jr
 

Years back my diesel tech advised me to buy a Smarty Jr for my '03 3500 truck.



He had the truck, and I left the Smarty Jr with him to look at. He was using the "regular" Smarty

on his 2500.



I don't know if he "tried" my unit on my truck (or another), but I KNOW he did not leave a "tune" on my truck.



Question: If the Smarty Jr was ever used, BUT the programs were restored (stock tune replaced in truck

ECU and the Smarty tune "reloaded" into the Smarty) does that mean my Smarty is "LOCKED" to my VIN number or another vehicle he may have tried it with?



This was a long ways back and I now live half a country away from the tech, so I can't ask him if he played around at this point.



How can I tell? Someone who wants to buy my supposedly unused Smarty Jr told me if I plug it into ANY OBD II vehicle the window will show "###" if my unit is locked, but we aren't sure if just using it once and putting the tunes back unlocks it again so it could be used with another vehicle.



Thanks,

Bob

If it was used and then returned to the stock tune then it should be unlocked. I have returned mine to stock and used it on another truck.

Thanks- I wrote to MADS and they also confirmed that.

On ebay people were insisting otherwise is why I sought the wisdom of this group.
THANKS!

using a smarty Jr on another truck
 

Good info, but does it have to be set back to stock before removing from the original install?
Thanks

If you want to be able to use the device on another vehicle (or re-sell it to someone who does), the device needs to be connected to the tuned-vehicle, and
the original program on the vehicle must be re-loaded.

Once that is done, the Smarty Jr will again be unlocked and ready to be used on another truck just like a brand new Smarty Jr would be.

Bob.

Thanks for the info, I appreciate it.
