Title: C5 A6 ECU into B5 S4 Post by: wildwildwest118 on April 03, 2013, 07:55:11 AM I have a 2001 S4 6 speed with an APR chipped H box that I'm wanting to replace. My friend has a 2000 A6 6 speed with a stock K box. What would need to be done to make my ECU work in his car and his in mine? If it can be done.
Title: Re: C5 A6 ECU into B5 S4 Post by: ddillenger on April 03, 2013, 09:16:50 AM Just install the ecu. As the a6 doesn't have an immobilizer, the keyways match and it'll plug right in. If it were a 2001 you'd have to modify the ecu plug. Softcoding on APR chipped ecu's is locked, so if the ecu is for a tip and the a6 is manual (or vice versa) it likely won't work right.
The a6 has a Bosch Maf, the S4 has hitachi. You'll have make sure to install the correct maf for the ecu. Title: Re: C5 A6 ECU into B5 S4 Post by: wildwildwest118 on April 03, 2013, 11:10:44 AM So since both of ours are 6 speed, I should be able to just swap the ECUs plug and play?
