These are some benefits of this setup:
- Expect just about every aspect of the car to feel better.
- Improved throttle response (especially between shifts), little to no cruise partial throttle jerk.
- Stable and smoother idle.
- Acceleration is noticeably smoother.
- Gain HP/TQ (8-20 hp is the norm, mod dependent)
- Increased gas mileage (I get 1-2 mpg better mostly highway)
- Ability to run a bit more gap. It's like driving a new car, you won't believe the difference.
- Handle 650+ HP, tested to 800whp
- Run more boost
- Greatly reduce or eliminate partial throttle cruise bucking.

Thanks for posting this! This kind of stuff is what helps the whole scene move forward 
Now if someone could come up with a kit that was already soldered, with the correct connectors and not charge an arm and a leg... Who would buy it?

Nice work, thank you for sharing with the community.
It's already out there, its called the spoolinup used cop kit.

I love this!!! How big is the gap between the valve cover and the coil? Is there a 3 wire coil that would sit a little lower or did you already look. Thanks for the write up!!!
Wires go to:
- ground
- trigger
- 12V
- tach

I saw that, but those have 4 wires. Is there a write up for the evo? I saw those on a Miata site here
