I recently purchased an accessportv3 and installed it yesterday with the OTS Cobb stage 1 tune. Just figured out how to set the gauges to display on the screen and have read the OAR (constantly at -1), FAR (is good), and the last 4 gauges positive ignition correction on all 4 cylinders. Here is what I discovered after a short trip, 1 and 2 read zero with a little positive correction occasionally but 3 and 4 are a bit all over the shop, both giving almost identical readings which are erratic and high. Like 30+.
Any ideas why 1 and 2 seem good but 3 and 4 are not what would be expected?

I just went to the car plugged in my AP3 and went through and reconfigured the gauges and this time all readings are sweet. I am guessing that perhaps I had 3 and 4 as ignition timing which may explain my readings. So at the moment all seems OK.

Yes you were eyeing total ignition timing, which can be helpful if you know what your looking for.

The only time I have ever checked the ignition timing was when turning the dizzy to set the timing or to check the advanced vacuum unit was operating. And that was done with a hand held light not a digital display.
