I recently got a HKS GT supercharger installed on my Z by GTM, and when I got it installed I went for the F-con Vpro with ECU flash. However despite the ecu flash my service engine soon light has recently been coming on, and the codes that are setting it off are: P2A00 & P2A03. I would definitely like the know what the problem could be, since I am getting tired of seeing that light on when I shouldn't be seeing it at all.

 

Bad 02 sensor......

 

do u have to flash the ecu when u go with the vpro?

 

To avoid the codes that you will get when you upgrade to a standalone, yeah. Plus a ecu flash is just an all around good thing to have done when you go FI.

Anyways glad to head that this is only an air sensor problem, I was kind of worried there for a little while. Good to know that I will be fine opening up my car.

 

why would a standalone throw codes when a piggyback wont? Can u explain?

 

You paid GTM a ton to finish your car, why not have them handle it?

I got the same codes a few months ago. They are o2 sensor codes. Mine were caused by a small crack in one of the welds on my Crawford HFC's. You could not hear an exhaust leak, but it was just big enough to suck in some air and freak out the o2 sensor.

Welded it up & reset ECU. No problem since.
