What the deal iz fellaz? One quick question. The other day I got an error code P0420 which said it was a Catalyst System efficiency below threshold. I took it to the dealer and the said the computer had to be reprogramed and have the software updated. Now does anybody know what exactly what in the software was updated when updating the ecu? By the way when I got the car back the car felt much peppier.

 

Did they charge you??

 

Yeah man they charged me $85 to reprogram the ECU. They wanted to charge me an additional $85 just to check it but good thing I had my own scanning tool.
