Relation between ignition timing and cam and crank trigger.

Relation between ignition timing and cam and crank trigger.

If the trigger 2 is set to cam position and VVT angle recognition in a vehicle equipped with VVT, does it have any effect on ignition timing?

Is only the crank trigger involved in the ignition timing?

[Vaughan]

Ignition angle is always relative to the crank position. Engines with VVT from factory have trigger systems designed such that the cam trigger moving within the factory VVT range can't cause issues with crank syncing.

[Yamamoto]

The position of the ignition timing when VVT is OFF is determined in conjunction with the crank timing at the time of the first trigger correction.
When VVT is running, it always monitors how many times it is offset relative to it.
The LINKECU is fine.

I think this question has something to do with this.
The HKS ECU had a problem.
When trigger 2 advanced, the ignition timing synchronized and the engine was damaged.
HKS ECUs should have been modified in the current firmware.

※日本語
点火時期は最初のトリガ更正時に、VVTがOFFでの位置をクランクタイミングと連動させて把握しています。
VVTが動作したときはクランクトリガーを基準に何度オフセットしたかを常に監視します。
LINKECUでは問題がありません。

この質問の意味はこの件が関係あると思いますが
過去のHKSのECUでは問題が発生しました。
トリガ2VVTが進角した際に点火時期が同期して動きエンジンが破損しました。
HKSのECUも今現在のファームウエアでは修正されているはずです。
