what is different about the last number in your ecu. on my cars year it is C, 8D0 907 559C what is the diff between the ecu with N or P and if i get a ecu with achip in it but the last letter is different wlii it work

 

sorry sorry not the last number ,the last letter

 

N & P might be negative and positive.

 

um dont think so

 

i cant belive nobody knows what the difference is

 

dose anyone know if these ecu are interchangableC,N,P

 

most ppl wouldn't really care about the last letters of ECU...we would go on a site and buy or order a performance ECU that fits our cars make, model, and year...

 

WELL IF ITS CHEAPER THAN WHY WOULDNT I LOOK INTO IT. if your not going to help than fine but i didnt ask for your smart *** remarks

 

i wasn't being a smart *** its just a alot easier to do that...if u go GIAC its $400 which isn't bad at all...i was tryin to save u time

 

On mine, the 018P is for manual, and the 018Q is for tip quattro. On miine which is a DBW car, they are not interchangeable.

Your mileage may vary.
