Hi,
The P8 CAN be done in teh software too, but that means you have to get a new map from someone else if yours doesnt support it, unless your mapper can just enable. Most dont know how to. Also, your rev counter will read half if you just do it in teh eprom.

The weber dwell control is just a switch at low RPM. Why does that concern you? No, it is not removed.

Yes, teh knock control is fully active, why wouldnt it be?
