For those of you that used this setup. I am just about to upload my ECU file using the Simon tool for the AA tune. Please excuse some of the "noob" questions but I just want make sure I do not damage anything in the process. What is the best and easiest way to connect a battery charger? Is there a particular one I should use? Is it absolutely necessary to use a battery charger? Should the battery charger be connected during the entire process? Anything else I should look out for? I have been real busy lately and I have very limited time to do this. I really appreciate any input from you guys. Thanks in advance.

Yes you should use a battery charger because the tune process can go anywhere from 10-20min, so there is a good chance your car will cut power before the flash finishes.
You hook up the charger to the terminals under your hood. They are on passenger side, the + is covered with a red plastic tab and the - is just a metal rod connected to the side of the car. When you find the + terminal just look slightly below it and to the left, its connected to the body of the car.

Get this charger

DO NOT get the one that plugs into the car lighter port.
And shop around I was able to find the charger for a about $60 new.

I also used the Simon tool to flash my 325. My charger is a CTEK model that works quite well. You can hook up the charger through the jump start terminals, an if you want a nice quick side project get a short metric bolt with "m5" size and use the supplied hard wire leads to install the direct plug-in cable that comes with the charger.

Also see the following link to see where to connect the battery charger / tender if you don't know where to connect it.

How often have you reflashed your car already?

For warranty work? Dealer had no idea?

How many AMPS should I set the battery charger to?
