Is there a manual or tech sheet for the CDI8? I'm after max spark frequency. I know the CDI1/2 units had a max output of 650Hz originally, and that was increased to 1Khz. What is the limit for the CDI8? Is every channel limited to 1KHz say, or is there an overall output spark frequency limit. Just looking at possibilities for a high revving multi-cylinder engine and CDI is one option.

many thanks

From the MoTeC wesite:

Designed to drive up to eight low-impedance CDI coils, the CDI-8 effectively combines an 8 channel ignition expander with an 8 channel CDI module in one compact unit. The circuitry can reliably deliver 450 volt primary voltage at 15 000 RPM (or at 30 000 RPM for 4 cylinders). The output stages deliver up to 200 A into the CDI coil primary.
