I'm completely new to tuning and looking to start tuning on a friend's project car. I have an AEM wideband kit on the way. In searching some, I found that people have used the EGR Pintle Position Sensor input at the PCM to allow the PCM to report wideband data, so that it can be logged along with everything else from the ALDL. The problem is that I am seeing various different information on which pin this should be.
Here's some specs on the setup:
87 Trans Am (was a 305 TPI car)
Aluminum L33 5.3 V8
4L60E transmission (earlier style bellhousing, not entirely sure of year)
2000 LS1 F-body harness
Custom conversion harness that plugs into the original factory firewall connector and then into the LS1 harness
2000 "0411" PCM - not sure where it came from
LS6 intake and factory injectors off my 2004 LS1 GTO
LS2 cam and timing cover
So, which pins are the ones to use for the EGR or A/C pressure sensor? I have seen stuff saying pins 9 or 55 on the blue plug are the EGR. Any real experience on which is which?
