1990 Mazda Miata turbo
3.3 ECU with Dual VR w/auditrigger, Knock, EGT, LCD, PS2
Mazda has a Dual Optical CAS wheel so the ECU has been converted to dual Hall inputs.
CAS wheel running on the stock engine mangagment looks like this on the scope
My plan is to remove one of the inner slots on the Cas wheel <via TIG welding or similar> and setup the motor as a full sequential capable unit <currently running the stock waste spark coil pack though>
Firing order is 1-3-4-2 and the wheel looks like so, the direction of rotation is marked with the arrow and I've labelled the TDC side of the slot for each cylinders event with its corresponding number <matching the firing order>
If anyone has a suggestion on which slot i should be removing <long or short slot> to make for the simplest config it would help greatly.
