My plan for the trigger setup is like this: * Primary trigger VR, 60-2 wheel on the crank pulley |

Trigger setup plans:
* Primary trigger VR, 60-2 wheel on the crank pulley |
| * Secondary trigger HALL, a vane wheel and fork style sonsor on the back of the cam wheel |

* Secondary trigger HALL, a vane wheel and fork style sensor on the back of the cam wheel
** with 60-2 primary trigger, the sectrig pulse can be almost anywhere: keep it min 18 degrees away from the primary trigger tooth that comes after the missing gap. ** the best placement is probably 72 deg ATDC (any cylinder: ign outputs can be rotated easily). reason: this position is also outside the ignition window (typically 45 BTDC-50 ATDC with ALS), a requirement of old 1.0.x firmwares. |

Q: This kind of setup wouldn't be that much trouble configuring for in VEMS right? Look at the middle picture, where should this window be placed? (in cam-degrees)
* one of the crankhome-VR (134 BTDC cyl5 in the original config) pulse should always see high; the other (62 BTDC cyl1 in the original config) should always see low voltage level => the 5-window HALL setup is just as good as the 1-window. Just make sure the crankhome is positioned close to the middle of the tooth (so even with some belt-sloppiness, it's surely there), and you're done |

'If the sensor pulls down to ground, or outputs 0/5V signal (or min 0/3V) than it's easy to use with VEMS, choose sectrig=HALL in webshop.
* if you use 135 tooth primtrig and also crankhome VR: ** one of the crankhome-VR (134 BTDC cyl5 in the original config) pulse should always see high; the other (62 BTDC cyl1 in the original config) should always see low voltage level => the 5-window HALL setup is just as good as the 1-window. Just make sure the crankhome is positioned close to the middle of the tooth (so even with some belt-sloppiness, it's surely there), and you're done * But with 60-2 primtrig you only need camHALL, the crankhome is not needed (only 2 sensors total) |
