MaxxECU Audi S2 / S4 / S6 (AAN, ADU, ABY) RACE Plugin Extra ECM kit 1859

This is a plug and play kit for your AAN, ADU, ABY engine.  For USA, this is for your urS4 or urS6 (or an engine conversion using the factory AAN harness)

We have installed several of these in local customer cars with good success.

This is a plug and play setup.  We provide install and tuning services as well.

We are currently running the RACE ECM in our extreme 10vt build (but with a custom harness).  

This is kit #1859 as found on the MaxxECU website.
