Well what hasn't been explained completely in simple terms is the benefits the C5 ignition brings to the table.


What Gary from PowerArc informed me of in a phone call is the C5 has the capability of selecting retarded curves, 3 of them.

The benefit this brings is we can select retarded curves to compensate for these conditions, like pinging, bad gas, heavy loads etc.

I've asked Paul to post the 4 selectable advance curves so we can see the differences in them as they come, pre-programmed.


I had mine set for the most retarded curve at first. That's also what it was set for in the video I took.


It ran better than it ever had.

I changed it to most advance, which matches the stock advance curve and it was a totally different beast.

It would rev almost instantly to full rpm with NO spit or pop and accelerated out on the road as fast or faster than it ever has.


As I showed in the video, the idle increased.

This tells me there's firing going on where there wasn't before telling me something good is happening.


It's a good system.

I'm looking forward to when I get the flodding #2 carb changed!


I think we all have a really cool ignition system available to us now.

The possibilities are open to us for other things that were impossible before.
