Stillen HFC vs. BERK HFC

Josh@STILLEN · 04-17-2009, 01:17 AM

Actually Jesse, Berk is dead on when it comes to the function of the secondary O2 sensors based upon my conversation with my R&D guys today on a different application that rolled into this discussion.

My understanding (and I'm in marketing, but privy to a lot of the tech going on) in regards to these sensors (including their function on previous Z's and the G35/G37s) is their drivability control, the secondary fuel trim function, when you're not under hard throttle situations where pre-loaded maps take function. Idle, cruising, CELs can be affected.

I'm not going to comment on your knowledge, obviously I would have no idea, but in regards to this car, engine, and applications, I wouldn't be so quick to discredit some of the people posting on this forum..

X2, but still the 2nd O2s on these cars do not make adjustments to the Fuel trims period. Ask Technosquare or UPREV and they will tell you the same.
