Peugeot 106 motore tu5

GENERAL
1

I’m setting up an ECUMaster EMU Black on a Peugeot TU engine.

Configuration:

  • Primary trigger: 60-2 crank wheel

  • Secondary trigger: single tooth cam sync

  • Full sequential ignition + injection

  • Crank sensor: 3-wire Hall sensor

  • Cam sensor: single tooth

Current settings:

  • Trigger angle: 114°

  • Primary wheel: 60-2

  • Cam sync pulse appears around crank tooth ~26 (counted after the missing tooth gap)

  • Trigger scope signal is clean and stable

Issue:

The engine almost starts, but I’m still getting occasional intake/exhaust backfires, which makes me think my crank/cam synchronization reference may still be incorrect.

Questions:

  1. How should EMU Black correctly determine cylinder #1 TDC compression with a 60-2 crank wheel + single tooth cam sync?

  2. Is trigger angle enough, or do I also need to configure cam phase/tooth position differently?

  3. Is there a recommended way to define the exact cam sync tooth reference relative to the missing tooth gap?

  4. On Peugeot TU engines, what trigger angle / tooth reference are others typically using?

I have clean trigger scope logs if needed.

Thanks.
