Now, what are the chances of my warranty being void with the JB3? No matter why I go to the dealership, I should always take it out?

Then uninstall the JB3, then check for codes again, and if there aren't any, I'm set?

Since I have little to no experience under an engine bay, I'm going to Matt@Camber-Toe to have it installed, then hopefully from him, I'll understand on how to uninstall/install the JB3 by myself.

What USB should I get to update the firmware?

Also..a big one, for the JB3, I read something about how you can only change maps when the JB3 is connected to the computer. I was kinda confused about this. I thought you only need to put the car in AUX mode, then press on the pedal to switch maps. Which way is it?

Any help is appreciated.
Right now the JB3 ships with two maps (map1/map0) and comes default on map1. You need to use the JB3 software and USB to change maps.

Install is VERY easy as there is no need to access the ECU and its 4 plug and play sensors you tap. Its a 15min and probably 5-10min job once you do it once. You will spend more time looking for the sensors then installing

Can't wait to hear your feedback and congrats on the purchase!
