Changed:
[image of the fabricated stainless steel mounting adapter] so the VR sensor is more central related to the wheel

* 60-2 factory made crankwheel on pulley (from Opel Astra X16SZR), diameter=140mm mounted on the Daewoo engine (pulley drives air conditioner and alternator)

* 60-2 Opel Astra X16SZR factory crankwheel pulley (diameter=140mm) had to be mounted on the Daewoo engine so the air conditioner and alternator are driven via V-belt as before (the Daewoo engine had multirib belt, and it seemed easier to mate them this way). However, because of this, the 60-2 toothwheel was not centered any longer. Therefore:

* we fabricated a [stainless steel mounting adapter] so the VR sensor is more central related to the wheel. This has been slightly adjusted since than, for smaller gap.

Changed:
* VR sensor mounted with appr 40..43 mm, so it sees the missing tooth earlier than it would from the factory VR sensor location. This is a side effect of the mounting: the reason for the adapter was to make the sensor align (better) with the crankwheel.

* The factory mark was 4 teeth (24 degrees) off because of the Daewoo-Opel hybrid. We checked TDC through an open sparkplug hole (much after the engine had been started :-)

* VR sensor mounted with appr 40..43 mm, so it sees the missing tooth earlier than it would from the factory VR sensor location. This is a side effect of the mounting: the reason for the adapter was to make the sensor align (better) with the crankwheel (read above).

* The factory mark was 4 teeth (24 degrees) off (compared to what we expected) because of the Daewoo-Opel hybrid. We checked TDC through an open sparkplug hole (much after the engine had been started :-)

Changed:
There are signs that gap between 60-2 crankwheel and VR sensor (with the home-made adapter) is too big.

Apparently the distance increased somewhat since original mounting.

Sloppy VR mounting problem - gone

The gap between 60-2 crankwheel and VR sensor (with the home-made adapter) was originally a bit too big. At cranking the signal (low amplitude because of low RPM) was susceptible to noise.

Changed:
* It usually doesn't start on first crank now
* It usually didn't start on first crank
Added:
Since the gap had been made reasonable, it start OK.
