1M on track: Threw some codes: 2C3A and 2C39
I'm not sure anyone has had these codes show up or not, but wanted to put it out there for forum input. (Yes, did a search.)
Was on the track at Thunderhill, driving aggressively, but not hitting rev limiter. The two codes appeared on my P3cars ODBII boost gauge (that has other functions besides analog boost) after my second run. No check engine light. Engine ran normally, and I finished the track day and drove home without issue.
Only other mod besides boost gauge is Berk Midpipes.
Can't think of a reason why either of these mods created the codes, which are interpreted as:
2C39 LSU dynamic too slow
2C3A LSU dynamic too slow bank2
Spoke to Bryan at Berk technologies, he said: codes related to the primary O2 sensors located in the downpipes. That would be the forward most sensors, closest to the turbochargers. It is not related to the midpipe/catback portion of the exhaust as everything is happening up closer to the motor. There are no sensors on the exhaust system after the downpipes.
This makes sense to me.
So, I cleared the codes (using the P3 cars boost gauge), and have been driving all day without another code showing up. Engine still behaving normally.
Any thoughts?
