Hey guys, I have a 2002 Audi S4, which I bought used. The previous owner left all maintenance paper work in the glove compartment.

I was looking through it and noticed one line that read, "Revo Stage 1 Flash S4"

Does anyone know what this could be?

Search!

It appears to be a tuning company that does flashes for the s4 like APR, GIAC etc. Meaning your ecu has been flashed and your car is hopefully making more power than a stock s4.

 

Does anyone know how to check if my car IS chipped?

 

Assuming there is no markings on the ECU itself.... A boost guage would let you know pretty quickly you dont have one do you? I bet you can find out using a VAG-COM, i wouldnt know how to though

 

check your ECU its self and see if it hasa sticker on it, or you migt be able to get the nuber to the place it was doen at maybe you can call them and give them your vin and see if they could tell you........but thats just a little searching i dont think it has ever hurt anyone

 

good idea! i'm not really sure where my ECU chip is anyway, so I'll probably just give the place a call. thanks!

and no, i don't have any boost gauges...

 

the ECU is under the front cowl cover I hear it is a pain to get to, you have an audi you might want to invest in a boost gauge just and idea
