Yep, the XDi box, now tested by Electromotive in Virginia, and deemed trouble-free on testing did not 'see' the VR sensor. Never has in my hands.

You can see the VR sensor output. It looks good to my untrained eyes.
Wires all there and in the right places and connected, tested from the 23 pin plug that would fit to the XDi box through to where the wires go in the system.

What can be wrong?

I am no further forward than i was 44 hours ago/4 weeks and $400 worse off.

The lack of detection has been attributed by Clewett to my installation, so I changed everything to their suggestions, then he starter is noisey, so I added suppressors everywhere and will on Sunday add a direct ground from the starter to the battery.
Then the circuit has been damaged by me because the crank sensor cable routing was too close to everything.

I then at their suggestion returned the XDi to Electro at my cost, and my cost to ship back as it is all my faulty.

The side suggestion is to convert to a Hall sensor.

The conversion lead is in the Clewett kit, bit telling that imho.

Overall, i think the design of the XDi is past it's sell by date, is very sensitive to EMI and why not sell it with the Hall sensor rather than the noise prone VR?

Electromotive gave me a $16 discount mind on the $165 sensor.

Costs so far are around $2500 and not a spark in sight.

If this last step fails, i have an (expensive) plan B.

This will have cost me more than my Carrillo rods!
