Here is a couple of quick snapshots of a log run I did this morning.
One is with the 2002 Camaro M6 B4309 'zeroed' out. The second log I simply re-loaded the stock 2002 Camaro B4309 Table.
The first decel shows External Wideband readings well below 14.63 AFR. The second shows stoich was hit on decel very rapidly, compared to the first. A few disclaimers. The Pids I selected were primarily for another tune/log goal. Willing and able to log identical IAC DMA pids and do one run down a hill with no TC, another with.
Perhaps the IAC function is simply allowing the RPM/MAP to fall slow enough to allow for adequate STFT switching?
Anybody else had a similar experience?
