i just received an apr ecu in the mail... and i would like to try it out on my car tonight .. i dont think i can sleep and wait till tomorrow.. after extensive search.. i really didnt come accross any straight cut article on ecu swaping .. so i was just wondering if you guys would be nice enough to help a brotha out ?.. So what is the absolute safe way of doing this?

2000
6spd
apr ecu only.. without emcs
no vag tool

do i really need a vag.. or can i do without it ?
much TIA

As NIKE says..'JUST DO IT".

Plug it in and start the car.

Went with the APR, huh? I am sure you will love it.
Anyway, unscrew the black box that holds the ECU. Only unscrew the screw in the back half way so you don't have to put it back in. (what a bitch) Lift up the lid of the box and undo the metal strap, take out the old ECU, and unplug it by sliding out the tabs. Plug in the new APR ecu and turn the key to the "on" stage. Let it sit there for 3 minutes. Meanwhile, redo all that crap up above.
Now just start the car up and enjoy.

And if you got the EMCS option... make sure it's on the "chipped" mode and not "stock".<ul><li><a href="http://www.goapr.com/support/ecu_a4_s4_a6_late.pdf">APR's ECU replacement instructions</a></li></ul>

Jim, are you around the W. 7th St. area?? If so, I have seen your car several times...in fact, do you eat at Jubilee Cafe??

Yes, the Borla is up and running. Aside from the killer spider and stripped nut, it went well.

Just to save the time involved with the potential of a bad ecu or chip.
