Its been a while since I have been on here... anyways. Im looking to get a chipped ECU but its from a 1999.5 B5 and mine is a 2000. Of course the ECU has a different code as well... just curious is this would work on my A4. The person claims it would.

 

Um don't qupte me on this but i don't think it will work cause the 1999.5 is non DBW and the 2000 is different engine codes also

 

I thought the 1999.5 was DRIVE BY WIRE and the 1999 was non dbw... i mean, why else would they have a 1999.5 model? So that guy was full of it?

 

1999.5 = non drive by wire
00-00.5 = drive by wire

There are plenty of half year models. Well actually there are NO half year models according to Audi. There are only minor modifications made halfway through a production year. You don't go to a dealer and by a "1999.5".

 

what is drive by wire

 

on the pre 2000 A4's, the throttle body was controled by a cable connecting the gas peddle to TB. On the Drive by wire cars, there is no physical cable, the throttle is controlled electronically - "wire".

 

It basically takes information from the position of your gas pedal and controls timing, boost and the throttle electronically.

 

Beat me to it Jared. Hey, check your inbox, gotta question for you.

 

didn't get any mail?

 

So that ECU is a no go then.
