I got the engine back in the car, everything connected up and checked the settings in the Omex ecu for the new crank sensor. Adjusted the ignition timing by 0.8 due to the different trigger wheel.
B207 first missing tooth is at 117 degrees, the LE5 is at 90 degrees
Cranked it over to build up the oil pressure and noticed no crank signal on the Omex screen. Hmmm, after a bit of internet searching it seems the Chevrolet crank sensor is in fact a 3 pin VR sensor, not a 3 pin Hall sensor
A quick rewire and adjustment of the settings back to a VR sensor, as well as removing the internal link inside the ECU, saw a crank signal detected
But it was a weak crank signal and with a bit of adjustment (so the crank sensor cable pointed to the top of the engine rather than the side of the engine) it was soon sorted out.
Then it fired straight up
I reset the timing with a timing light, due the different trigger wheel and it's now happy at 13.406 degrees
