I have an EEC-IV EFI 434 cubic inch Ford motor with an EDIS-8 setup. I use a 36-1 Crank Wheel and a VR sensor. I set it up to 10 degrees advanced and it runs great. However sometimes when I run the motor hard, the Crank Wheel will slip. Then the timing will be too far advanced. I had to be towed home twice because the ignition timing jumped.
The Crank Wheel is sandwiched between the Crank Danper and the Crank Pulley. There is some clearance built-in that allows me to adjust the Crank Wheel to set the timing. The VR sensor is fixed in place. I lock the Crank Wheel with two set screws through the Carnk Pulley, but it still slips under hard acceleration.
How is the Crank Wheel normally secured into place?

Re: Crank Wheel Slipping
It should be bolted in securely - you probably need to change things so it has no adjustment provisions. You can use the Trigger Angle setting or make the sensor bracket adjustable instead.
Re: Crank Wheel Slipping
Something wrong with the fixing. I assume it is spaced from the boss rather than just touching the 'V' of a pulley?
Mine is bolted in place - the trigger wheel has slots for adjustment - and hasn't moved.
