What is pulling the timing here? (lt4)

[mJolnir]

the car is a c7z06 auto, it has a AFE intake, LT headers, O/R x pipe, 16% lower pulley and borla noisiest exhaust, yesteday we had a 1/2 mile event and the owner said it felt like it was nosing over in the top end so i did a log.

Saw that timing on each gear went less and on 5th i only had 8 degees of timing on it, that was a lot of powe left on the table. its not IAT as the table is set to not pull timing until 133 degees, and its not the ECT as the table is set to not pull any timing until 213.

So, where did my timing go?

you have the basic IAT table and then there is a multiplier for the IAT2

[8850]

You need to log manifold temperature. That is what is pulling your advance. There are two. The one that rises with boost is the controlling.

You need to log "manifold air temp"

Edit: I'm too slow. 8850 is right

i thought that was IAT2 but now i see IAT2 is falling for the whole pass. Looks like its time to add some water injection.
