More wacky problems from this same car that will not return to idle routines 100% of the time.
Here's the latest. We took it to the track and were doing some nitrous shakedown passes on a small shot. He made a pass and burned off all but 2 of the straps on the plugs. I look at the log and at about 6K RPM timing jumps from the flat commanded 13* to a solid 29*. First thing I checked was to make sure that there was no modifier table screwing me up. The IAT sensor is tricked to read 73* temp all the time. ECT temp was solid 190-205*. TPS read 100% throughout the entire pass.
There are only 3 tables that show 29* timing in that region of cylinder airmass (0.80 and up). The park and drive idle tables and the max torque table. Only the torque table goes up to 8K RPM. I changed the torque table to 14* and the idle tables to 12* in order to see which one it is. We changed plugs and did a few blasts on the street but it never fluctuated from 13*.
How does this max torque timing table work? Is there a way that I can identify which table is in use while scanning (besides what I already did)?
This is a 99 F-body tuned in Open loop MAF w/ HPTuners. It is a wet direct port shot.
