I took my car to the track this weekend and noticed that my timing is running about 3 Deg below what I have set in my timing table. I have both the high and low tables the same. It shuld have been 18 deg but the logs showed it to be running at 14.5 and 0 knock retard. Whats causing this?
A ton of things.
Intake temps, coolant temps, torque mngt and many more things can drop timing a few degree's. You need to figure out in your tune what is causing this.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
It is the intake temp table. I totally missed it.
Yeah exactly what 5FDP said. It is 100% going to be your IAT, ECT, or torque management tables. Check them out. Usually the IAT table is the culprit.
