detonating, datalogs show super high advance

[torquefreaks]

so i can hear it detonating on the last few runs after my tuner played with the maps. We blew the headgasket at 5600rpm on the dyno.
specs are ka24det vw vag coils, waste spark, 1000cc inj, hx40 17psi.
tune attached said sata log was too big?

You can't power through detonation, when you hear it LIFT. That noise you hear is the good in your motor going out the tail pipe.

Fix the problem before you hammer it again.

If a headgasket blew you could very easily have other damage. Be prepared for problems after fixing headgasket.

Without any turbo experience I can't speak to the spark map, check some other turbo maps for spark ideas.

Don't tune your motor on kill settings, be conservative and your setup will last a lot longer.

Zip the data log.
Also, why do you have 2 spark tables, if you don't have table switching?

I have already replaced the head gasket with cometic instead of the felpro. I wondered the same thing Hidro as he was tuning not I. I previously had just spark table one. Is it possible the spark table with combine the values and that will cause the high advance. Since replacing the gasket I disabled map 2 and it pulls good no det. He was talking about using the second map for meth inj but like u said and I realized there table switching isn't enabled nor is it wired or setup inside the ms case.
