since i have an 01 can i take a 00 ecu and swap it so i can use the j31 file in my car..just a weird thought.

 

Not sure you can. I'd be wary of changing ECU on a DBW car.

 

haha, good luck finding good software,look into dahlback.

 

isnt there a new valve job on the 2001 engines

 

my option is dahlbac or upsolute but i havent decided yet

 

Go upsolute.

 

why would you say them. i have personally talked to them and they seem like they are ahead of the game when it comes to tuning.

 

Hey i am new here but i just got a 2000 A4 1.8T and i put the dahlback chip in with the dahlback diverter valve and a n75 valve and damn man what a diffrence i am looking to do a lot of work to the car so all the help will be appriciated but yeah dude the dahlback ecu is deff worth the 800 bucks

 

2000 ECU's can ONLY be used with 2000 cars. They are different.

 

Yeah I've got a 2000 with the ATW engine... ATW was ONLY in 2000 if I'm not mistaken.
