Re: How do I get spark signal for chassis dyno
This may work: Your engine has COP coils, each held in by a Torx screw. Remove the beauty cover and expose the coil pack, #1 (passenger side, rear bank, first cylinder). Take a 10" length of #16 or #18 insulated wire with the ends stripped about 3/8". Wrap the wire around the coil form twice (the plastic/epoxy squarish thing) and connect the reference signal lead to the wire ends - twisted together. You have just made an inductive pickup coil.
