RS Autosport info on ignition drivers

Thoughts? I wasn't aware that VB921s had a habit of dying. But the dwell settings us miata guys are running sound like they're in the danger zone.

I don't want to hit the track for a 20-minute session next year only to have my engine cut out, and find a fire behind my pax seat.

not that applicable to us really,as the standard 'miata' mods don't utilise the MS ignition drivers (the VB921's).

We use the stock ignition drivers.

interesting article nonethless, but in our case, there's no need to worry.
