Looking at service info, several modules contribute to operation of Exhaust Flow Control Module (flaps).

'08 automatic Vette, flaps opening at idle with procharger tune. Any way yo monitor / control this with EFILive? Don't see a direct PID / chart / map / tab so far in cal.

Will post additional findings. Thanks!!!

Well, I fixed it it was just a bad actuator (leaky diaphragm). And judging from my findings and lack of responses there isn't much in the way of monitoring it, it is a separate module with input from BCM also. Thanks anyway! :)

Boost thanks for posting.

Yet another module... hmmm, with BCM involvement.

LOL, I am taking tons of GM training recently and they keep saying that additional modules are being added for "serviceability and reliability" (?)
