Code 30FC... Flash related?

j1gilles · 06-17-2014, 08:40 PM

Having a pesky issue with a half check engine light that occurs when applying moderate throttle (like to pass a G37). The car continues to run fine and after I restart it the half check engine goes away. I pulled codes and the only code I get is a 30FC Exhaust fume turbo charger density. This started shortly after upload a revised backend flash I was sent to correct another issue. Has anyone else had issues with this code that turned out to be flash related or should I start pulling stuff apart? Thanks!

Boost targeting issue. Could be flash related, altitude related, boost leak related, vacuum line related. Hard to say.

Did you change your JB4 settings to use the flash?

Yes, I think I have it figured out... Wedge emailed me a new flash bin and it seems to be running strong with no check engine light.

I was hitting boost target, not much of an "altitude" issue out here in Chicago and it directly correlated with the upload of a new flash.
