How to upgrade the JB3 Software

I can't seem to find it.. Looked on n54tech, burgertuning and on here.. I know you have to plug it into the computer and what not but is there a way to upgrade it without taking it out of the ecu? I think I read in a thread a while back having to do something near the battery compartment? Not sure if this is any way related to the JB3 software upgrade though..

Reason I ask is because I have the JB3 and I just bought the chip burner... Kind of getting impatient! ><! But I don't want to have to pull it back out after I install it.. if thats the case, I might as well just wait... -_-

It's not painful at all. You don't have to remove the whole JB3 unit, just the little chip from the unit - no wires involved.

I would advise getting a spare chip or 2 from Terry. It is handy to flash a chip, then do a quick swap.

Get an extension cord. You can then upgrade the chip in one minute.
