I did a test on PIN 30 today because I am curious as to what is going on there with my car ie: grounding vs. voltage. At testing I have a constant ground at PIN 30 with my clutch pushed in or out and in gear or out of gear.
Since I did an AOD to 5 speed swap and my car was originally a speed density car converted to mass air, my O2 harness does not have the jumper wire like the later mass air cars do. So I also performed a voltage test @ PIN 30 while cranking the starter and I get 9 volts @ PIN 30. What I understand is any kind of voltage @ PIN 30 can cause damage to an A9L ECU. But I have never had any issues using the A9L other than a temp high idle when pushing the clutch in as I do using a C3W ECM.
Does anyone think there is damage to the A9L regardless of it seems to function just fine? And If I am going to use the A9L should I make that PIN a constant ground with no cranking voltage going to the PIN such was cutting the PIN wire and grounding it or is there something else I should be doing to make it work correctly?
